Winter break? Glad Gentle Giant is still keeping an eye on me.

still working ok?

I’m glad I’m not the only one!

Thank you!

Well that’s obnoxious!

Not to mention both the MSB and PowMr had higher output than the EP ever,, so his "efficiency " rating is nonsense and missing critical data, EG; solar input on each unit

Yes I noticed a discrepancy in my shunt that threw the numbers off by a certain percent. Hence the adjusted numbers on the screen compared to the video footage.

@@BeeneEnergy did you have a theory as to why the numbers are off from the charge controller screen?

@@jasonbrown467 from my tests I believe they are measuring the input power from the panels. Not taking into account efficiency losses before power goes to the battery. I have seen some that are so optimistic though that a 400w panels shows 430w. That’s just some miscalibrated something inside. Has to be...right?!

Yes it’s massive!

I currently want to run a 12v system since I lost a 48v inverter after 5 years. Either of these should be fine with a string at 72v. The thing is I may only be able to put 2 or 3 250 Watt panels on a 60A CC since I'm running at 12v correct? I'm shooting for the cheaper units as I could get 2 vs 1 epever. Do you recommend the blue or powmr after a few months.

@@cutweldngrind I haven't gotten finished testing the 60a version of the MakeSkyBlue. At the moment it appears the only reason to go MSB is if you want the features. Such as wifi monitoring. If you just want a simple charge controller PowMr seems like a reasonable choice.

The powmr? Yes it can charge 36v packs.

@@BeeneEnergy Great, thanks.

Yep. Specs should state about 80voc max when using a 12v battery. So two 24v panels in series usually works too.

@@BeeneEnergy thanks very munch i can use my pure sign wave inverter i have 10 230 watt panels 24 volt panels

My PowMr fan burned out in 2 months under max solar panel loads, the MSB is still going strong. PowMR is just a MSB prototype, version 113, older, less refined, and prone to overcharging , especially on smaller battery banks. MSB is just better.

Connect your panels in series to the powmr mppt ....you will get more power that way....am in Ghana and I use the same mppt and it's very great

I’d go for the epever of these three as it’s passively cooled and a tad more efficient. Aka won’t bug you by making noise and will make the most of the limited panels you can install.

@@BeeneEnergy thank you, what about epever duoracer? What you think? Looks like it's a ready for double battery setup

@@campervan-vlad I have not used one of those but it looks slick. Looks like primary use case is keeping starting battery topped off and healthy while also charging leisure battery.

@@BeeneEnergy thank you mate

Thoughts: This converter does have current limiting built in. So it shouldn’t self destruct in that scenario. It’s designed to use the battery as a buffer load of sorts, so it will have a hard time keeping voltage at 48. Might fluctuate too much especially when adding loads to the inverter. I wouldn’t recommend it. But it might be possible.

Thought of another piece. The charge controller needs a 48v battery connected in order to auto detect what voltage range to output. Otherwise it might default to 12v?

@@BeeneEnergy Thanks for your input. Doesn't look like I could use it as a buck converter then. Do you know of any 72v to 48v bucks that can handle at least 40A output? I have a 48v inverter and a pair of 48v ebike batts I'm using for backup power, would like to use my collection of ryobi 40v batts in series as well with the inverter.

Wow I forget how far we’ve come in such a short period!

I have had the Optimistic readings with this style of controller. Could you tell me about your setup? Voltage of panels, series or parallel, battery voltage, etc?

@@BeeneEnergy 12v reliable 3000w inverter. 2 120ah lifepo4 in parallel. 2 x 325w solar panels wired in series. Total voc 80v, but usually stays between 55-75v. My msb flickers between program/setup and regular display when it starts producing more than 300w of pv input. My msb is wired with dual pole dc breakers. Since I am using lifepo4, I set the controller at 14.4v on both D01 (float) AND D02 (max). D03 low voltage @ 12.2v. D04 disabled. I calibrated the D06 to match my battery bank.

@@ilingwang1168 That all seems well within spec. Crazy that you are having trouble with your second unit.

@@BeeneEnergy update. It’s still doing that LCD flickering back and forth thing. But it’s been performing a lot better the last 2 days. It’s been doing 3.3kw per day the last 2 days. I guess I’m going to keep monitoring, until I have to replace it. There’s someone selling a used/like new Victron 100/50 for $200 locally. I’m considering buying it.

I do indeed, why do you ask?

@@BeeneEnergy I just want sure if the cheaper one was an mppt or a pwm.

@@moldycupbleachpower6782 all three of the ones in this video are MPPT. They all have dc to dc conversion happening internally. I can hook a 49voc 10a isc panel up to the powmr and get 300-400 watts of charging. If it was pwm I’d be limited to 120w max.

I must be reading something different than you. I tested these with a single 400w panel and with two, hence two readings for each. Epever did better in both situations. MSB tied in one and did better in another compared to powmr. What conditions were you In where the MSB did amazing?

@@BeeneEnergy Spring, winter and Fall cool weather production from 800 watts in panels into a 12 volt battery bank produces constant 90-100 % solar panel input on the 60 amp, at max load. But your video is putting 800 watts on a 40 amp MSB, on a 12 volt bank? It cannot handle that, sorry, your missing so much data, seems you set it up to promote your website PowMr, and EPever sales, and skew MSB, which beats them both , easily in long term. The EPever overheats and goes to pwm, and uses pwm in shaded conditions, so many flaws in it, your not considering at all

@@BeeneEnergy PowMR is just a version 113 Make Sky Blue and kept overcharging my AGM, going over 15.1 volts and triggering my inverter to shut down . The PowMr fan blew out in 2 or 3 months, my MSB under same load is on its 4th year now, never overcharges, and completely destroys the EPever in cloudy, or max input situations due to efficient cooling system. These things matter.

@@affordablesolarguy Hmm I’m still not understanding. I measured how much energy the charge controller would pull off the panel(s) vs how much made it to the battery to get my efficiency number. How would you suggest I do it? The MSB actually did best when it had 800w of panels available to it.

Wow that’s nasty, I have had a source from China not have any of a product in stock and I had to wait a couple weeks for manufacturing to keep up. So it’s possible the testing comment is true. But they really shouldn’t have the product listed on eBay if it’s not available :(. Yes I sold a bunch of those 305w Jinko’s. We have some 310w REC right now that are about the same size, but none of those Jinko’s since that batch. I’ve been playing with Growatt inverters and they seem like good units.

@@BeeneEnergy Sweet, are they 72 cell? BTW I'm the guy that wrote the code, and developed the BMS unlock for Jehu Garcia's scooter batteries. featured here: kzfaq.info/get/bejne/i9OImqigtNOZqWw.html I'm going to start doing some reviews myself, trying to find the time.

@Brad Cagle Yes they are 72 cell modules. Oh yeah I don't watch all his videos but I saw that one, knew there was someone watching out for him! How did you find what the BMS needed? Did you get a hold of a bike/scooter that used those batteries? I love recycling like what Jehu does with batteries. I've purchased a lot of batteries from batteryhookup but nothing where I had to trick the BMS to get going, always kept it simple.

@@BeeneEnergy I don't remember which forum, but there was some scooter forum where a guy had a complete scooter and he monitored the data being sent to the BMS. I just wrote some code for Arduino that would send that that data to the BMS. I do the same kind of reverse engineering a lot at work, I'm a software engineer and we have to integrate with existing systems that customers may have. What are you asking for the panels?

@@BradCagle very nice! One of the things on my list is figuring out how can communication works with inverters and BMS’s to see how it can be better utilized. We are asking $110 for the 310w panels. They are new old stock, sat on pallets in a field for a bit.

I've actually got another couple videos where I was surprised to see the opposite. Efficiency went up when I ran with a higher voltage!

@@BeeneEnergy Thank you for your response! That is really strange, but happy to hear. This was the only reason why I was considering wiring 2x455W, 50voc panels in parallel in my 24V system, but that makes no sense now. Still a bit afraid of the 105V max input for a 24V system on the PowMr 60A. Not sure if that is 105Vmpp or 105Voc. Any experience with this?

@@DrenImeraj If you’re that close you should keep it in parallel. 105v is voc so you’ll be bumping against it in cold weather. I realize that depends on your climate too but here in Texas I wouldn’t recommend it in series :).

@@BeeneEnergy Ahh, makes sense, thank you! Do you know the behavior of the controller when that is exceeded? Is there potential for a catastrophic failure?

@@DrenImeraj Potential, yes I'm sure. I've observed it go just barely over voltage and the controller just stopped charging and threw an error for high PV voltage. I'm sure if it was high enough it'd burn something up.

I mean LiFePo4 battery

@@szekerespista3758 yes it would be normal to drop to 0 when full.

@@BeeneEnergy thanks!

I’ve got my 60a v119 in, just have to find time to run some tests on it. Will find out soon!

@@BeeneEnergy is it the wifi version I want to see what the app and connectivity is like

@@joshuabest100 yes it’s WiFi. I agree, I am excited to see how good the UI is.

@@BeeneEnergy looking forward to it i have my notifications on

It is possible with pwm but you lose 2/3 of the panel that way. With mppt I still get the full wattage of the panel. Also it’s hard to find a pwm controller for a 12v battery that won’t implode with a 48voc panel.

@@BeeneEnergy then i am good if i have 3* 24v panels to charger 3s battery with powr 60A

Yes just don’t use more than 80voc when at 12v battery. You might need to run those panels in parallel.

​@@BeeneEnergy I have been puzzled by the parallel layout of solar panels. Let's say one has 2 parallel branches. One at ~60v with three 100w panels and another branch at ~70v with 2 larger 250w panels. What would happen at the charger controller? Obviously this can happen in reality even when the panels on the two branches perfectly match, because the site can get shade and clouds. The panels has blocking diode so the higher voltage can not flow to the lower branch.?.

awesome info bro

Having had both PowMr and Make Sky Blue, I absolutely agree with what you're saying based on my data. The MSB v118/119 firmware is better than their clone (PowMr).

I'm a big fan of the EpEver - The unit modulates should it get near full rated current and fethers down the charge to ovoid overheating - mine goes into PWM mode only when the solar falls below 10watts to reduce internal driver loads - mine charged 0.6a on a clear night from a full moon - as mined located in a cubard i did fit extra vents

Internally they are not the same, even though they appear identical on the outside. There are videos that show the internals of them.

Yep lots of 30v panels (60 cell) around. I had someone else saying this as well. My plan is to do a similar video/tests with a 24v battery so that the panel voltage is much closer to battery voltage. I also have some 60/120 cell panels to try as well as these 144 cell panels.

You are over excited and making accusations. If you calmly came to me with claims or suggestions I’d be happy to address them. What makes you say my epever can’t handle a 48v battery for example? That’s asinine. Ever heard of over paneling? The Chinese manual for a powmr doesn’t address it but in my observation it’s a current limiting device so having more than 720w is ok if within the voltage range. The powmr even has circuitry to shut down if voc is too high. I’ll say the epever I blew up didn’t! Of course with the epever I sent 90v in when its max was 50. Please explain your claim that the MSB will blow the epever out of the water. I’ve got a 60a v119 now along with a powmr and epever. And a whole assortment of batteries I could connect! I will say, I plan to run these tests with a higher voltage battery to see if efficiency really does go up when the panel voltage is closer to battery voltage.

@@BeeneEnergy Ok, here is the issue, you don't know anything about solar, your an actor, your deceptive, you just showed people how to do what the manual specifically states to NEVER do, and that puts people homes and lives in danger of burning down. You showed them how to properly blow up their equipment, and you did not show the line loss connections you had on any of the equipment, and you had HUGE line loss on the MSB and PowMr. Your lack of attention to detail, and inability to follow directions makes you dangerous to aspiring do it yourselfers. If your focus was to help people instead of make money, you would follow directions and demonstrate safety and compliance with user manual instruction. The Make sky blue and Powmr out perform the EPever easily , especially when you realize you can buy 3 for the price of 1. So dollar for dollar, buying the EpEver is like throwing money away for people trying to create clean energy on a budget. 60 amp MSB is 100-120 bucks, PowMr 60 amp is 60-80 bucks , and mine are 4 years old, still cost less than the lowliest Epever, and can run over 3000 watts without ANY issues. If you know what your doing.

@@affordablesolarguy This is where i’m confused. Out perform in what way? I ran and grabbed my 24v battery so I could test your arguments. I am all about learning. The only thing so far is that you claim my efficiency numbers are off since the panel voltage was so high. So with a 24v battery my panels will be right below 2x the battery voltage. (25.6v nominal LiFePo4). Right now I have four 400w panels in parallel and I’m testing with the MSB. About to hook up the powmr. Also you seem to be implying I like the epever better. I bit the bullet and bought it to test with, all my setups are using PowMr charge controllers. That’s what I started with and I haven’t been convinced to go with anything else. Unless I’m wanting a hybrid inverter in which case the charging is taken care of. Let’s have a conversation. Let’s go back and forth and figure out the best way to do this. Let’s not yell at each other. That ok with you?

@@BeeneEnergy efficiency is how much of your pv potential makes it to the battery. In your own video , both the MSB and Powmr pull in MORE energy and beat the EP, when they are withing the instruction manual specifications, and beat it substantially. Your loss is due to your shunt, shaudy wiring, and incompetence , in the form of LINE LOSS. Strange how your Epever doesn't suffer this at all, maybe you should show your wiring job , since anyone who owns these units knows , the loss is completely your fault, and probably deliberate. You get bigger bonus's on more expensive units I'm sure. I get constant , 90%+ solar input during cold season, and 75% when panels are hot. Sometimes, I get more power than the panels are rated for in the cold season, because my wiring is correct. DO YOU GET IT? Efficiency is NOT a measure of your incompetence in wiring, its the percentage of pv potential that the controller can harvest.

Troll

I guess the powmr just squeezes into the weight qualification at 1.1kg then!
