This series is about using DIRECT DC solar (PV to Load) power for heating. No battery or inverter required. This is PART 2 of the DIY PV2L space heater series - I hope it helps you to gain a basic understanding of PV2L heating concepts.
NOTE #:1 If you a beginner and find this video a bit overwhelming, don't worry. Check out this more beginner-friendly version of this concept at: • Simple PV Solar Heatin...
NOTE #2: this video does not show the electronic safety controls which are mandatory for such a project. That would require a separate video.
Did you know solar panels can heat your home or shop directly? This is called PV-to-load or PV2L for short. Right now it's more of a DIY venture, but perhaps will become mainstream. Part 2 shows some of the basic modification work to convert an AC quartz infrared tube element space heater to 24 / 36 /48V DC operation PV-To-Load directly off of a solar panel array. Direct solar electric heating is more efficient than other setups.
This video shows how to work with Quartz Infrared heating tube elements, including basic demonstration of heating element re-wind. Ohms formula calculations (commonly referred to as Ohms Law) is covered. 12V is possible but deserves its own video.
There wasn't room in the video to cover all the details. If there is sufficient interest, I can continue the series to cover more topics. Due to massive video editor failure, this video could not be made any longer than it is, at least not 1080p. I almost was unable to get it to process, took dozens of attempts.
NOTE modifying space heaters requires the utmost care and attention to ensure safety. Educational purposes only.

Background:
I heat my home and workshop with several modified space heaters powered directly by DC solar panels. The solar panels connect straight to the space heater with nothing in between. I thought I should share the concept as it might help a few people. What prompted me to do so was a recent winter storm we had, we needed all the heat we could get.
It's possible to make a DIY Solar Electric Space Heater (Quartz infrared for example) by modifying off the shelf heaters. Due diligence is certainly required, this type of setup could burn down your house with solar panels.
This video series is about building PV-To-Load (PV2L) quartz infrared heaters which directly utilize solar panels to heat a home or
building. I currently heat my home and also my metal building (solar workshop) using this method. PV2L bypasses the traditional method of charge controller / battery / inverter and gives a new option for efficiently operating appliances directly off of solar power. If you're using a grid tie inverter with heating loads, it makes more sense to put the power straight into the heating appliance and save wear on the grid tie inverter.
PV2L does not mean the appliance cannot accept a normal DC input. Batteries can still be used for this type of heater.
The first video in the series ( • Heating my home with s... ) is a quick introduction and a look at one of my most recent heater builds. It uses custom infrared
Quartz Tube elements which are configured to run directly off of the DC power from a solar panel. I have several custom quartz and standard resistance heater prototypes working at this time.
High voltage DC carries a severe risk of electrocution, so my heaters always use safer low voltage DC to power them. However even low voltage DC creates arcs and poses several technical challenges vs AC. The components of an AC space heater are not suitable for DC at all. Starting with PART 2 we will delve into the issue of converting space heaters from AC to DC safely and retaining their built in safety devices which were never intended to switch Direct Current loads.

i tried this out prior to getting batteries and inverters for my solar panels. Had good success with it. Essentially take out all the regular safety equipment as thats going to make it dangerous and keep your voltage low and the amps high and it seems to work alright. Had a max of 450watts going in to a 750w heater and none of the cabling got warm and and ran fine for quite some time.

Overall great video, with really cool ideas presented in a compelling way. My only slight complaint is that it seems no one recommends soldering to MC4 connectors. A good crimp is all that should be needed. No? There was some talk of insurance people being overjoyed to find solder on even a single MC4 connector when investigating a fire, as it allows them to lay blame on the installer.

@orangezeroalpha Thanks!!! Believe me I know those insurance people :D I usually solder my MC-4s after a good strong crimp to improve overall conductivity. If I leave the solder out I always worry about resistance over time. It's a choice I make for myself, others will surely do the same.

I already managed to 'convert' a dehumidifier (500ml ~26w) to run on a 50w panel but that doesn't work as well as i hoped, i need to further optimize and automate it but i am REALLY intro "PV2L" systems in general. I also tried PTC heaters but could not get it to work (almost at all), it seems to be much more complex since it self regulates and needing much more power initially before settling in it's intended power usage range (more difficult via small PV?). I however already had some quartz dual tube (2x 400w/240v) heaters laying around.. One had a burned out tube and this video helped me to "salvage" that (cut it the inside in half). Now it E-X-P-L-O-D-E-S heat within seconds and only is able to run """"safely""" for about 3 seconds lmao. Absurd, but a fun experiment how Ohm's Law works in practice. I would love way more direct solar heating / PV2L content.

Hi, very cool projects, you're right the elements are tough to match to PV and let's say I melted and burned up some stuff in the process. I was able to get some PTCs running nicely off of a solar array last winter, but they are finicky and frustrating due to the reasons you mentioned. My first attempt was some truck cab heaters years ago, but they are loud due to the fans. So I started modifying space heaters. Really hoping to do some more PV2L heating stuff soon, will post as soon as I can :)

Enjoyed this one very much. I did not realize quartz heaters used resistive wire to generate heat. A bit disappointing actually, hoping there was some cool quartz vs electricity physics thing going on. a) You mentioned the wire (that brings current to the element) is thin. I suggest verify it can handle the current. At same power out current can increase 120VAC/24VDC = 5x b) When winding own element, is it easier to measure wire resistance & cut to length before winding or would it be unwieldy c) Thinking get most efficiency at max power point resistance Rmp=Vmp/Imp. However that is resistance when hot. Could calc R_hot by measuring Voltage across a hot tube and get current from an in line meter or current clamp. After taking a couple data points of R_room temp & R_hot, could create an equation that allows one to take the desired R_hot then map it to R_room. That way you know where to cut wire at room temperature to get the desired R_hot. d) Wondered how an AC switch can select 4 power settings, excluding off, with just 2 elements. Had to go back to 16:54 to get my answer! Looking forward to DC safety measures. I suppose DC maintains arc more easily because it does not disrupt current flow with zero crossings 2*60Hz (or 2*50Hz) times a second where the air breakdown has time to recover.

Thanks, music to my ears, glad you liked this one :) Too bad video editor wouldn't let me go up to an hour. Tried 3 programs trying to get this video to render. For some reason I just love the quartz elements. Yes they are rather simple. I have parabolics, PTCs, conventional heaters but keep coming back to quartz for the infrared glow. So far I haven't had problems with the wires overloading, I am extremely cautious and careful to avoid fire. The last thing I need is more suffering. Also I am able to stay near MP on the panels - until the neighbors' trees shade the panels that is. You are right about DC. It wants to keep going and going, AC has 50/60 chances to interrupt, so they are very different animals IMO

i'd like to see how you control these safely when DC power is being used. i live offgrid with a 14.4kwh lfp battery bank and 2000w of panels. i'd like to run a space heater from the 48v nominal battery. rather than through the 2500w inverter. i'm in the mojave, so "winter" is almost over. still want this knowledge for the future though. the only diy system i know how to use for heat presently is having an element in an old water heater, remove the insulation, let the steel tank radiate into the room. the guy who invented and sells the electrodacus BMS/charge-controller has an interesting experimental heater. he uses old solar panels "run in reverse" as indoor flat plate heaters.

@solarpoweredge Жыл бұрын

Sounds like fun. Bypassing the inverter makes a lot of sense. After I move to a bigger property I hope to go off electrical grid. Or at least get a lot more panels :) Part 2 got very little traffic, I'm thinking folks don't want to do all that work. But I may record a video later on the safety controls, (there are many ways to do it). I was very careful to emphasize safety because I didn't have ability to do any more recording. And didn't want people to disable them and risk their homes. Have you tried PTC heaters? I've used small cab and PTC heaters for years. They are quite cheap and just work. PTC is safer. 48V elements are available. Matching them to the battery and/or solar panels and wiring up may be the only chore. Made this video of the small ones kzfaq.info/get/bejne/rbFjks-DuNTYgpc.html I've seen electrodacus' work, starting with his solar BMS from way back. Very impressive. A guy named I think, Edison Electric, made a heater you paint on the wall and run wires to. Pretty neat stuff.

I found some 48V resistance-style heaters for sale online, but not too cheap. The cheap semi-DIY option is 48V PTC heater cores (searching for "48v ptc heater" gives results). Now I'm thinking about getting a couple. These need a fan to push air through them. For example there's a 200w 48V, only 15 bucks to try it. 4 of those could be a 200/400/600/800w variable power heater. Mount securely with 80mm DC brushless fans blowing through, hook up to a circuit breaker and away you go. They have plastic mounting frames to attach a fan to, I use M3 standoffs for mine to keep the fan farther away. Maybe I'll get a few of these 48v models to make a video, they should be a pretty easy setup.

What about creating a movable element that can change from big to small as you have more or less power. This could simplify the systems ability to be safe and adaptive. I’ll be doing some things this summer with solar and will be running some tests and putting together some builds.

@solarpoweredge 5 ай бұрын

@Nofukzgiven Sounds good! one way to do this... using multiple heating elements, and combine them according to level of solar power available. 2 of my heaters use this setup. If the sun is dim, I switch out the other element. Recently I found "diode chains" could be part of the solution too. Because they can practically track the max power voltage of the solar panels. Last few videos covered that. Anyway I hope to test diode chains combined with existing resistance-based solar heaters. If I can get a chance to finish that project I'll make a recording.

Good info! There are small inverters used on individual solar panels which, as I understand, converts the output to 110 vAC from each panel which avoids high voltage DC from a PV array. Would appreciate your comments regarding whether this type of system would be able to be used for the direct solar heating you are investigating. Thanks.

@solarpoweredge 6 ай бұрын

@davidwalker2942 Thank you sir! 100% it can work. What you could do is use a transformer and inverter circuit. As long as the voltage output did not exceed 110vac for the space heater. It doesn't have to be pure sine wave. It does not have to be perfectly regulated either Previously, I looked everywhere for small inverters (not like the tiny one I showed on the channel running small stuff, but upwards of ~500-1000 watts continuous) for this purpose. But I could not find anything satisfying off the shelf. However I once heard of some folks building larger inverters that connect straight to the solar panel to run appliances. I believe there is a guy on yt doing that but cannot remember his name at all. It works - problem is where to get the inverters. And many people don't want to build inverters or get into major electronics projects. If I ever run across a good option for everyone that's very DIY friendly, I'll sure post it here.

@orangezeroalpha 4 ай бұрын

Look at the cost and complexity of those small microinverters that appear to be all the rage in the US right now. Often, microinverters work with only one or two panels per microinverter and cost more than my charge controller which can utilize 10-12 panels. They often are installed on the roof, the hottest part of your house, which helps to explain their long=term reliability. I'd say any advantage from directly converting to AC or running many panels in series to get high DC almost entirely disappears if you design a system without huge cable runs. Long cables aren't cheap either... Any of these direct solar heating options would likely work best with one or two panels by themselves, mounted on a wall near where they are used connected by a short cable. If someone gives you ten microinverters for free maybe it is a different story, but sit down before you get the price of that stuff. Affordable it is not. I believe some of them need to all link with another expensive box elsewhere so they are all synced to the grid, which in direct DC heating would also be pointless.

Nice video! :) You are very skilled in both the lab. and editing room! In Northern Sweden, during the dark and cold winter, it is mostly too cold to run solar thermal heaters (even vacuum tube systems can't produce usable heat when it is sunny but -30°C / -22°F ). So that is why I am considering powering 240Vac 2kW hot water tank heating elements directly with 6 panels 450W_STC each in series, yielding approximately 2 kW NOCT @ 240Vdc. :) I know about the safety considerations, but since the submersible heater inside the water tank can't tip over, or catch fire, I am more worried about electrocution, or solar panel fire. What more than correct DC-circuit breaker, correct thermal fuse, and some kind of "DC-ground fault protection device" do you recommend from your experience? My friends that are electricians ain't too keen on installing such systems without adressing the "dynamic nature" of running panels without inverters and such, but that is mostly due to practical inexperience with this setup, and no official "electricians code" to follow :)

@solarpoweredge 5 ай бұрын

@walp86 Hello in Sweden and thank you for the kind feedback :) you are right this is unfamiliar territory and most professionals shy away from anything so "unconventional". It's up to the DIY'ers to advance the state of the art in many cases. The system you are building sounds very exciting indeed! I would suggest that with high voltage DC, there is zero room for error. Margins (meaning extra consideration in case of an oversight) should be designed in everywhere, from breaker ratings to wiring and connections. And to consider dropping system voltage and raising current if possible. Thicker wires are reliable and have no moving parts, they cost more short term but lower the chances of electrocution. That said, the most important part of handling HV DC is understanding insulation requirements and preventing various faults (like arcs which can start fires) and hazards to human life. My opinion or recommendation is to protect the wires themselves with conduit when possible and use proper wire rated for ~1000vdc. All connections should be crimped and clamped so they can't move. Arc fault, thermal protection and proper breakers for sure. Prominent warning signs and labels for HV DC are a good idea, hopefully they will keep anyone from assuming this is a normal system and being careless. I've found a common error to be assuming 240vac is same as 240vdc - nothing could be farther from the truth. They are very different and have different requirements. An appliance or device rated for AC cannot at all be expected to pass high DC voltage safely. Unless specifically rated for DC (which is rare). Unfortunately, heating elements fall in this class. It can certainly work, but all caution is advised! On top of that I recommend thinking through failure modes. For example, what happens if water leaks out of the tank and pools on the floor. Will it be "live"? What if someone steps in it? If the tank accidentally runs dry or the thermostat "sticks closed", what will happen? I try to imagine different ways the system could fail and harm someone, and then figure out how to prevent it or protect others from harm. Well I hope you have a good day and will find some or all of this writing useful :)

Ran across this researching. I just got a 200w AC Lasko mini heater and a Gaiatop 500w. Why do these heaters have a wattage surge when first turned on? Is it because the cold heating element conducts better, then as it heats the current flow drops? My Lasko (on my Bluetti EB70 meter) started out well below 200w, then rose up to about 280w over a few seconds, then after a few more seconds settled at 192w. No safety switch, just on/off. The other settles in at about 450w. Got them for the camper I live in since we`ve had very bad winter storms down to zero degrees here in Louisiana two years in a row. I have 11 mostly small solar power stations and an Ampere Time 12v 300ah battery with 2000w inverter, plug-in 20 amp charger, and 60 amp MPPT charge controller. But after moving to this lot I discovered winter sun is very limited and trees limit sun in summer to less than 6 hours. That`s not an issue for anything except trying to power a small window AC or heaters. So I`ve basically used it for emergencies only...and we had five extreme heat emergency power outages since June. I was called names for buying this stuff by relatives nearby...but guess who had air conditioning and a working fridge, freezer, microwave, lights, WIFI, etc each time the power failed? HA!

As far as the heating, they absolutely vary in power draw, temperature can affect them and even the way the heating element is constructed. It gets even worse when trying to run off of solar panels which constantly vary their power output and voltage. Fyi Part 3 to this video will be uploaded soon addressing some of the safety issues. I intend to do some more heating related videos as soon as POSSIBLE. Right now I've been to doctor 5x and on 3rd antibiotic plus a hundred other things, which has slowed video production waaaay down.

I bought cookers that can run off these and 12v rice cookers that can be powered by the 10 amp DC cig ports of my tiny power stations. My power doesn`t go off now. It`s so great to not worry so much because I`m in the boondocks, in a camper, physical disabilities, no car, so I had to set things up here far differently than a normal person. We were without power for nearly three weeks in 2020 after hurricanes Laura and Delta. Then the bad winter storm in Feb 2021. I could literally die without what I have.

I was wondering if a direct solar connection to a 100w DC 12 to 24 volt rice cooker would be safe. It has a fuse in it. I have to parts to try it but never have. In theory my 100w panels that actually produce 90 to 102 watts are a perfect match, but I typically use it with my little Golabs r300 because it has safer LiFeP04 cells. Scared my lithium ion power stations might go into thermal runaway amping the 12v port to near max levels or needlessly reduce their cycle life. I keep an Onite LED bulb running off battery power so it doesn`t go dark when the power fails. Our power grid here in Louisiana is garbage. If thunderstorms or any winds over 30 happen...power`s gone...or we start getting surges and flickering lights, so I always have to switch to batteries before storms and disconnect my camper from the grid to avoid bad problems. Lost a laptop in June because of a weird surge and heard a loud crack of a spark in my fuse box that damaged my DC system. Afterwards my 12v lights flickered even when off so I had to disconnect the DC. I have plenty of Onite bulbs and can run lights where I need them from USB power banks or my 100w folding panels during the day. They`ll power a 5w light hanging in the shade under my roof to avoid UV damage. @@solarpoweredge

PV is unregulated, so caution is always advised. I ran a netbook from a panel in another video. Unregulated and risky... but it survived and actually worked. The rice cooker might be just fine who knows. I will certainly end up buying one and test it, probably will try to get that recorded. When running off the solar generator, you don't have to worry about voltage. But if you are in a state where batteries are scarce, there is PV-to-load as a last resort.

Hi if you want to try electric heat, a few 12-volt car truck cab heaters might help. They need to be placed on something fireproof (like cement board) as they are not quality units. A safer alternative is 100w 12V PTC heater elements, but you will need several. To heat a bedroom in an RV, probably need at least 500-1000 watts depending on climate, and that takes a larger battery (5-10kwh+) to get through the night. If you run a 500w heater for 8 hours a night, that's 4 kw/h and most RVs don't have a lot of battery. Here's a video about the cab and PTC heaters if you want to see examples: kzfaq.info/get/bejne/rbFjks-DuNTYgpc.html If money will not allow, you could use a smaller system to provide "supplemental" heat from solar and batteries. And use normal methods (propane perhaps) to get the rest of the heat. If you have for example 250w of electric heat, that's less propane burned. If you have access to a 120v outlet, even a single space heater can make a huge difference in an RV. All of this is just my opinions, but I hope it can help in some way. DD

… dude would you please build a direct solar connector to a heater box. You’ve obviously put a lot of time and energy into this. Why don’t you build a product that you can sell?

You are absolutely right, we need such a safe plug and play box. Most folks don't want to hack up their heaters for good reasons. I did work on such a design with a microcontroller but it's not done. Right now the number one obstacle is my health. These videos were excruciating to make. Nothing I can do about it. Health is true wealth, wish I had it.
