Good explanation. Bus Bars are the way to go when making multiple connections, much cleaner. You most likely mentioned this previously, a good source for bus bars is Midnight Solar. They seem to have a good selection for different types of situations.
And also I'll really like you to do a video on how you program the inverter after wiring the system. What are the things that need to be set on the inverter.. and am sorry if these questions are basic am just starting with solar installation and am trying to learn as much about it
I have a theoretical question.. I have a goal zero lead acid battery invertor charge controller combo box 1250 yeti.. it has 10 external batteries connected in parallel.... can I just connect up a external invertor as well.. goal zero seems to say they don't know how the goal ero box would react and could.cause a failure... .. any ideas
Nice short tutorial. My question goes thus: which among the inverters are we gonna connect the output wire/ load wires to. Or are we connecting the output on just one of the inverters
That all depends on the inviters. Some you can parallel the out put and some you can't. Mine have a coms board in them. So they can work as a master and slave for the out put. Hope this helps some.

Thanks Bobby. Wouldn’t it still be the same amount of power going into the battery regardless of how the PV is wired. If it is all going to one charge controller or two or three charge controllers for that matter, isn’t all of the power flowing to the same common battery? The exception would be as you noted , if different sized PV existed and wired to different charge controllers.
Yes your right. But as you know. This is just needed when you have different sized PV going to one bank. It's not ever the best thing to mix PV. On the same CC. Unless the electric values are all the exact same of the PV. If not the lower value panel will pull the rest of them down to it. Seen this happen where guys had 255 watt PV mods and a 245 watt mod on the same CC. He just had 2 of the 245 and 6 of the 255. The max he could get ever was 245. That's with ice and temps of 15F.. At that temps there should have been his max PV going in. But max we could see was the 245. In the case he had 2020 watts of PV. on a average sunny day he would see max 1400 ish watts or so. When we removed the 245 out of the setup. He was getting 1350 + watts on a average sunny day. That's just one that I can recall this min. But seens all kinds of things like this. That one too where so close in watts and Volts. You would think it woulf not been that big of a deal but it was. When we got him a new CC and added those 245 guys on that one he was seeing 400 ish watts from them a day. So just by this few sets his power had gone up about 500 watts + and hr.. That's a crap load of power when your trying to live 100% off-grid. Sorry for all this LOL.. Hope that helps..
NO !! This will allow them to both run off the same battery Bank! The AC side will not be tide together. You can do that with high-end inverters. But not the one's that you just plug in an appliance directly to ! Hope this helps some. God Bless
Yes sir !! Nailed it!! LOL But yes I have not ever had a bit of trouble running them. Maybe back when using lead batts and they where low on charge. Not with lipos. God Bless brother.
@@AGhostInTheMachine From what I know it's this in short and from what I know. May not be right on this. It's when one inverter is pulling a lot of amps and the next one is left with out the amps its needing to do it's job. That's from what I recall.
This is way you keep the inverters the same size. Also size your battery bank to handle the max loads you can place. I do 120%. So If I know I need to do 4500 watts. Than I size the bank to do like 14KW or more. Even knowing that can't ever happy. Like to have LOADS of head room ..
@@AGhostInTheMachine As the story goes having 2 inverters on the same battery causes the ripple effect. Ripple is wasted power, and has many undesirable effects in a DC circuit: it heats components, causes noise and distortion, and may cause digital circuits to operate improperly. ... Ripple may be reduced by an electronic filter, and eliminated by a voltage regulator. Or capacitors
I have two inverters and two sheds each has it's own inverter and do not mix AC output, can I connect to the same battery bank for input volts to the inverter?
Yes ! As long as the DC volts In for each is the same and the AC is not mixed. Your 100% fine I did this for 8 years. It's it's very common. Hope this helps. God Bless.
This is great! Very easy to understand! I am working on a off the grid style house and am just getting started on upgrading my solar, any thoughts on running the inverters into a regular fuse box and to house wiring?
I watched your video with your big solar array, and why they should be sized together for the different output's and shading zones. Very informative. I will be building im thinking 2 battery banks for a offgrid boondocking cargo trailer. Ill have enough room to put 4 panels on the roof, with a diy tilting frame. I don't think ill need to put them on seperate controls for shading, but want to make two banks for the weight issue. Ive watched a few videos on building banks, im thinking the bms and smart shunt will be the way i go for battery safety. I have 8 lifepo4 280ah 3.2 batteries coming, do you have any advice on if they should be/and how to wire the banks 12v banks and wire together for 24v? I am a newbie on solar and this will be my first build. So i don't want to waste money on going 2 12volt systems and controls if i should be building two boxes and wiring them as one with one set of charge controls for a 24v system. If that makes sense lol. I spent to much time watching videos, i had to take a break. But if i remember correctly all the systems were 12v i watched, and remember something about 24v being more efficient. Thanks if you have any suggestions, God bless brother!
For clarification. I will be putting a pvc pipe system on roof around the solar array frame for shower water, washing clothes, dishes ect. If im not parked near a flowing water source, ill be taking water jugs and a battery bank with a pump and filter for water collection instead of hooking up trailer and moving to it to fill the 40 gallon pipe storage system. It may turn out it'll be easier to just have a agm battery for that, instead of un hooking a bank, but will still be making two banks for the weight issues. If i have a failure in one bank of any kind it'd be nice to still have one working if say a controller or shunt went down.
@@yankey4 My battery bank is 24V. One charge controller is an Outback Flex60 and the other is an AIMS 12V. I should have realized that wouldn't work. Thank you, Bobby! (Both CC are MPPT)
Question I have 2 PowMr 24v hybrid inverters 3000w each I have 24v 600ah Lipo4 battery bank can I connect both inverters to the 1 battery bank? But can I connect 4000w solar panels to 1 Inverter to charge the batteries ? The reason why because I don't want to split the panels in half and run another set of wires from my roof down to the garage it's to much work
Yes !00% that is fine. You do not need solar on both inviters. As long as your inviter can take 400 watts of PV it's fine. You can run them both off the same Bat bank. Just can't combine the AC out put of them. With that some can be AC combine. Like mine have 2 PCB bords I can install. This will then combine there AC out put. Hope this helps some..
@@yankey4 each inverter has its own AC output but they are not combined they are separate going to a sub panel on separate legs L1 and L2 but will both be pulling from same battery bank is that ok?
Hi Bobby I have 15kv solar system installed.5kv 3 inverter with one power bank but there is issue on 2 inverter.every time 2 inverter beep for overvoltage busbar
@@zulqikhan592 Sorry I was using my phone to send last reply. Not saying it's a sound thing. It sounds like to me that you have a bad inverter. Or your wiring is not right.
@Bobby's Solar Homestead cool, so can I do more the inverters? I bought a portable classroom and want to wire a couple of them to the breaker box that's on the building so I can have power on all the outlets in the building. Do you think that's possible?
@@kylecampbell6953 No you can't have 2 inviters feeding into one braker box. You can but there is a LOT more to this. But if you don't know how to do it you will blow up one or both. Best way to do this is to have 2 braker box. One for each inviters out put. The DC in put from the battery back can be the same as long as they have the same input DC volts..
I wish I could show you a picture but it has the 2 hot poles that come down to the busbars/breakers. I can't do one inverter on the left pole and then another on the right?
5:57 you said if we want to add another charge controller to the system, we put up another set of solar panels and wire to number 2 controller. Did you mean to say if we want to add another set of panels? Probably is an obvious misspeak, but i don't know enough to be sure lol. And im guessing if you meant another set of solar panels, and wire them to number 2 controller you'll want to make sure the controller is able to handle the extra volts? Not trying to be a smart butt, im just trying to learn from your videos for my knowledge bank!!

Yes why not. I run all kinds of stuff from solar. 90% of my 120 volt loads run 24/7 off-grid. Thanks and God Bless.
Just to make sure I got it right- so if I have for example two inverters of 1500w each, that allows me to use , let’s say, a 2000w appliances?
