110722/1124h PST 🇺🇸 This is the 3rd time, I’m watching your instructional video. The narration is simple and very understandable for lay man. You gave me the idea of using 2 CCs in multiple PV array configuration. Thank you and best wishes.

OMG!!! Thanks for the presentation sir. You just clarified me on the biggest confusion I had on this topic. Thumbs up

Oh my gosh - Thank you so much for this video. I just spent an hour with a guy ranting at me that this couldn’t be done. So, so glad to have found your video! I currently have four 200 watt panels that I am planning on putting on my RV. But then I also got a diy mini-split ac unit to replace the roof air. The 800 watts will run it - but probably not 24 hrs a day, 7 days a week. So I am now looking at adding an additional four 200 watt panels for a total of 1600 watts. I have been stressing over the charge controller, the larger ones are so expensive. This just solved that problem! You just brightened my day! Thank You!

Finally! I've been watching videos and all I wanted was simple explanation and a simple diagram that I could understand and this video delivered and answered my questions. Thanks for a great video!

I think you explained this before, but it's good that it is now a separate video (more searchable). Having a separate video about this, and the contents of the video itself: very helpful! Thanks, Bobby!

I really needed to hear this. It was a blessing to me. I was about to get a whole extra battery bank!

I really appreciate the clarity of your explanation. Straightforward and easy to understand. Thank you.

My wife and I are in Northern Nevada and preparing to go fully off grid. We would like to charge (2) Absolyte GX (2,000 Amp hour battery banks/48 volt). We are looking at (2) Schneider Electric 865-1034 Conext MPPT 100 600: 6kW Solar PV Charge Controller for charging w/ (20 XW PRO 6848. We will be using 30+ LONGi 545 watt solar panel in two arrays. Thank you for posting your video.

Thanks for the advice, waching all the way from Fiji island

Thank you for the wonderful walkthrough.

Great Video, Bobby! I'm a new subscriber and just added 2 400w panels and another charge controller,.... so this was great. Love the idea of the buss bars, too!

I simply connected my chargers this way 2 years ago, all fine, just saying the advice in this video is right.

Excellent. Thank you so much for the down to earth explanation!

This is exactly what I was looking for. Thanks!

I did not know this was possible. Thanks.

Simple and effective explanation!

This is very helpful, and educative .❤

You. Are. The. Man. Thx so much for this upload.

im working on an rv application with renogy products and this is one of the few channels that doesnt assume your using victron (i cant afford) and your the only one to tell me to use a bus bar not some victron tied in hardware that talks to the rest of the victron products (again dont have, cant afford) i appreciate the consideration 😀

Great explanation with the diagrams helped. Liked and subbed, thanks for sharing your expertise.

Thank you, awesome so much great info, in one video!!!

Good informative video Bobby!!

you did a great job and on top of that look like John Belushi, who I love!

Awesome, eye opener for me!

Think you learn something new because of you bless you and family

You have an awesome set up there.

tnx for the video Sir, the content is so informative. i learn a lot. new subscriber from philippines.

I use charge controllers and grid tie inverters with dual mppt trackers to have multiple arrays facing in different directions

Fantastic information

Thanks so much!!! Very helpful

Good video. You can use different brands of charge controllers as long as, as you say, that they are programmable. I've even used a Schneider/Xantrex PWM C40 CC with a Morningstar MPPT, but I had bulk, absorb, and float settings the same. As for different voltages/amperage panels, in Series the amps should be about the same because voltage adds. While in parallel, the voltages should be about the same as the amperage is added together. Like you say in parallel a lower voltage panel will pull down a higher voltage panel, least common denominator basically. In series, a lower amp panel will pull down a higher amperage panel. It's a bit complicated for most, so it's best to keep like panels together on the same CC.

Thank You for the info!

very helpful, thank you!

112822/0521h PST 🇺🇸 Good day to you, My friend. I'm watching your presentation for the 4th time. I will be using 2 CC for my PV systems, that has been redesigned to charge 24V EVE (2X12.8V series) Previously the system was in 12V configuration. Thanks again and best wishes. 73s...

Great Video!

Thumbnail sold me

052321/1131h PST 🇺🇸. Thank you for the informative video on the subject. It was explained in simple and clear language for any one to understand the importance of the subject. In fact, for me it was. Thanks again. 73s...

Hey quick question Can i connect two controllers but one will deliver power from parallel 8 x 100 w panels and other deliver power from series connection 330w x3

Hi Bobby, I wish I had you here in UK, We are building a Motor home from scratch and I want to go big with solar. Ive had sooo much advice in Uk and everyone contradicts each other, Ive found the panels that will fit on the roof... 4x 365W Canadian Solar Mono Half Cell Panels - Super High Power Mono PERC HiKU and have no idea now how to complete it... Thanks for your Video, really helpfull....God Bless.

Morningstar has an interesting point paper on why their CC's don't need to talk to each other. Not sure if I can dig it up any longer. Cool subject I love having multiple CC's. For me it's all about virtual tracking and easing the load on my battery bank. I only do power hungry stuff during the day and if I always have an array facing the sun I basically always run straight off the panels and don't cycle the batteries. I don't think I've ever had my batteries depleted lower than 94 or 95% full.

Very nice video thanks for taking the time to make. I would have also liked it if you would have added in your diagram where to put the fuses. You just said in all the cables. There are lots of cables in the diagram.

Thank you.

Good info sir..

awesome info

Thank you. Thank you.

I have an Off grid Solar system. The Internal charger can not fully charge the battery , when on full load. Can I add a separate MPPT charge controller with its own 500w panel in parallel to cumulatively charge the battery.

Good information

I am trying to understand the wiring control map. You appear to have the negative busbar connected to 1) the negative battery pol 2) and the negative inverter pole. You connect the positive bus bar to the positive battery pol and the positive inverter pol. Then you connect battery 1 positive pole to battery 2 negative pole.

Very nice, detailed schematic and to the point. A similar video was done at the AltE store in 2019 but it was difficult to follow what was going on, since items used in the schematic weren't labeled. My only question is: can two mppt controllers, different brands but both 24 volts with same amp rating, work in this parallel configuration to one battery bank?

Great video. I am thinking of doing this with my small array so that I can flatten the curve and have more consistent power production throughout the day I'm thinking of facing 2panels facing SE and 2 panels facing SW. This would mean morning sun max And evening sun max and combined power at noon. Of course my power output will be less but it will be continuous instead of only peaking for 2 or 3 hours a day. This should allow my freezer to run directly from solar most of the daytime hours and only rely on the battery at night.

I want to add more panels that will exceed the capability of just one Renogy Rover CC. So, I bought a second 20amp Rover. Renogy says I can't do it. What do you say? Thanks.

Can you clarify programable? For example two pwm controllers set to charge a lead acid bank, most other settings are not like an mppt.

Thx !!

Hey that is a good idea, on muti CC! I'm going to make a play list on my other channel! Thanks Bobby on the information, GB!

Thanks!

Can you wire in controllers from different sources like hydro and solar?

Do each charge controller need to have equal amounts of amps? If one charge controller PV array is lower amperage will the lowest take precedent organ they be different amp outputs and both charge with it's full power input available?

Thanks for the video i have a question if i run two separate 240w strings to two diff charge controllers to one battery do i only have 240w total or 960w total how does that work

I get very confused when systems with different voltage AND amperage are somehow tied together. in the first diagram 6:30 would you say that the two series connected systems are connected to the battery parallel? What voltage range would the battery bank need to be in order to allow both systems work in optimization?

Hello there. Thanks for the awesome video, very clear information. I have a situation here that I don't know if I will be able to make it work. I have a RV that has a couple of batteries inside and a solar panel on the roof, and they charge through a DC-DC charger that has a MPPT controller and also allows me to charge the batteries while the engine is running. Now when the RV is stopped, with the engine not running, I rely only on solar. The solar panel on the roof, that the DCDC with MPPT is connected to, has 170w, and that sometimes is not enough for my appliances. So I was wondering if I could connect another solar panel to the batteries when I need more power. The second solar panel I want to connect is a portable one, has 200w and has a PWM controller. I would connect it directly to my batteries through some wiring I made, as you depict in your video. Given the differences on the controllers, do you think that could work? I don't think thay the controllers are programmable. Could I end up damaging my batteries? Thank you again!

thanks for the vid, lots of good info. one question ref multiple cc, can i use an 1 MPPT and a 1 or 2 PWM seperate panels on each but feeding the same battery bank ?

Would using two different charge controllers (CC) work in a setup where one CC is attached to a PV array and a second CC is attached to a wind turbine, then both CCs going to one battery bank via bus bars?

Bobby - would a combiner box work to do what your bus bar configuration is showing? Hoping to keep the system configured where a breaker or fuse will trip prior to the inverter. Our problem is setting up a (2) Absolyte GX 48volt/2,000 Amp hour (AGM) telecom battery banks and keeping them full. We will have well above 12kw-15kw in solar panels/strings and knowing if a string of panels is not going to shut the entire system down is worrisome.

Hi, thanks for your videos. Can i connect a (litium )battery battery bank to a solar charge controller and wind charge controller at the same time? I have 24v solar charge controller and 24 v wind charge controller.

Wouldn't the biggest reason be more amps in solar array than charge controller can handle like an arry putting out 120 amps on 2 60a controllers?

Excellent video fella, your really helping me understand how to setup my little solar project, i,m just so confused with the fuse side of things, your diagrams explain a lot but is there any chance you could include where the fuses are to be put regards to the battey and solar panels and charge controller, i know this is quite rude of me to ask but I'm at a loss

I have a 1500watt inverter with a 100 amp controller. Will these work together? I am just setting it up. Will a 12v 200ah battery work with this as well? I am not running a whole house just some small appliances and 3.3c refrigerator and 110 air-conditioned, just enough for a small room.

Can it work on a different watts panel like 250watt 4 on a different charge controller and 180watt different charge controller let me let know if it’s okay to connect

Hi Bobby. Thanks very much for your video. I am from Tanzania. I have 9 PV of 100W, 5 PV of 200W and 6 batteries of 200Ah 12V. Plz need your advice on the best way to connect them and what kind and size of charge controller and inverter I should use to make it safe and work properly.

Bobby if i can't find anymore chevy volt batteries im gonna sell mine if you or you know someone let me know i need more batteries keep it up brother

You're the absolute GOAT man!

WOW! You're.like my twin brother. We look identical!

Do u have to hook positive to one end of battery bank and negative to the other end of battery bank

I have a hybrid inverter working already. Can I add 2 independent solar charge controllers connected to their 2 solar panel arrays to the existing system, following your wiring diagram?

Bobby, educate me. If my battery has a bulk charging limit of 30 amps, normally I would apply a 30 amp charge controller and know that I won't exceed that limit. BUT, if I hook up a number of independent charge controllers in parallel, what is going to limit the current? If I hook up a couple of 30A (or even 20A) charge controllers at the same time, with the same programming I will exceed the bulk charging rate by a long shot.

I have a charge controller that states it is only rated for 500 watts and 40 amps. Since 500 watts equals about 5 amps why am I limited to just 500 watts? Just thought you might know. It is EPEver brand..

While one CC is charging the battery, the other CC may be trying to read the Voltage of the battery, but instead it will be reading the value of the paralleled CC giving a chance that the reading CC will stop charging. Right?

Hey Bobby, quick question about the PIP inverters. The low voltage battery disconnect has a default of 21V, but I change mine to 23 V in the settings. If the batteries run down to 23V at night, the inverter shuts off, but when it gets back to daylight, the inverter switches back on to start charging and it will eventually start producing power again when the batteries get a bit of charge. However, the low voltage battery cut off defaults back to 21V. So the next time the battery is getting low the inverter shuts off at 21 V instead of 23V and this is not good for me because my batteries tend to get out of balance at the lower end. The low-voltage cut off seems to be the only Setting that goes to default whenever the inverter turns off, everything else seems to be saved in memory except that. Have you or anyone else had that experience or know how to solve it?

It appears that your batteries are wired for 24 volts, as the left battery has its positive side on the bottom, wired to the negative on the bottom right side battery. Should be made clear for newbies looking to wire a 12V battery bank with 2 CC's. Or, am I reading this incorrectly?

good video its looks like battery bank is 24 volts im using 5 batteries 12 volt with different size panels 2 controller so the panel with the lowest power will win out over others correct ?

I am looking at running more than one charge controller because I need to feed divergent voltages. I need a six volt system and a twelve volt system and a 24 or 48 main system. Because of my security and other systems. Have found I can feed a load of tv and computer gear from a regulated 12 volt system

Can you run 2 charge controllers from the same solar array and charge 2 separate battery banks?

If battery is charging with 20A with one charge controler when you connect the second charge controller is it charging with 40A?

I Hello is this wiring diagram a parallel or series controller setup? I'm confused? I've been looking for videos and most only show what's called wiring two controllers in parallel. What is this called that you are doing compared to the so called parallel videos I have come across? Thanks for your time.

Hi thanks How to wire two mppt controller to a 12v system? You have caption it one battery but show 2 batteries.

One solar panel one agm battery one lithium battery used separately ,my question is can I use 2 charge controllers with the one solar panel

Then I have an issues I have 2 60a 48 v controller and my inverter is 96v while the battery 8 batteries of96 v also but controller can't charge

I am still puzzled some say there is no 12, 24 or 48 Volt panels and that how you hook them up is what determines the volts and amps coming to CC.

Great information. I just wish you would’ve taken the time to draw out switches, breakers, fuses, and a Shunt in your drawing. maybe you can find one and put it in otherwise great information.

💪🏼🤙🏼👍🏼

I have 5 batteries and 2 charger controllers atm not connected to a buss. Should i have them connected to 2 different batteries or the same one? Or even on opposite ends of the bank?

Awesome video. I have mixed panels on my system. 3 200 watt panels an 4 100 watt panels in parallel. Then 3 200 watt panels an 3 100 watt panels to 2 charge controller's a 50 and a 60 amp. Am I loosing much power that way.??

Morningstar can I charge without program on a computer

Can you come to missouri and help meeeeee, i live off grid , cant seem to get my solar kit to work correctly & all the numbers (amps, volts, etc.) make my brain hurt. Living on a generator, cant afford the gas to keep it powered .

Starts at 6:26.

All good man just bring on the sun lol

can you show us the fuses.

Im confused. This shows 2 batteries not 1 like title states.

Dude! Take a chainsaw to them trees!

I really need an answer
