I'm not going to lie that would be something new for me...

So I'm building an off-grid house... At about 25 ft from the house I will have a shed that houses the following equipment 4x MPP solar lv6548s 1x 304ah eve cells 16s with jdb 200a smart bms 1x 280ah eve cells 16s with jdb 200a smart BMS Eventually I will add a third and a fourth battery...

1.) Yes but it's not ideal... It'll probably get you to 80 or 85% charge 2.) they should work fine but if you can fit a fourth that would be better 3.) EP ever makes a great 40 amp charge controller but you need to make sure that it's compatible with 36 volts... If not they make a 50 and 60...

I want one

Oh yeah I see I had that confused I was thinking of inverter 1 and inverter 2 as a split face pair but really it's inverter 1 and inverter 3 as a split phase pair

Now what happens if I want to shut half of the system down during part of the year... Can I just shut off inverters three and four on the right... Or do I need to completely reconfigure the system?

I'm not sure if I found the correct configuration I have four LV6548s I would like to configure them split phase 240 volt... It should be a little over 100 amps I think I found the correct configuration in the manual

Appreciate it. I think this makes more sense. Thank you so much for helping me confirm what I was thinking... It almost makes me want to overbuild it a little further and have a huge safety margin

But then there's another thought... Do I really need to carry the full load of all the inverters or even of all the batteries for that matter? Let's say that I have a bus bar that is rated for say 300 amps, so, 50mm wide and 5mm thick... And theory if I placed The battery terminal of battery 1...

So I'm really trying to understand best bar sizing... I've seen a couple different ways to look at it Some people say that you need to look at what your maximum current of all items put together could possibly add up to Other people say you need to keep in mind which direction current is...

Hey y'all... I hope everybody's having a great day. Where do I go to get busbar material... I don't want to get junk but I don't want to be broke either Thanks in advance everyone

Kind of thinking about just building bus bars... I have a nice drill press... So it wouldn't be hard

I'm getting ready to start planning my build with 4, MPP solar lv6048's These are 48 volt, 6500 watts So I figured each unit will pull up to 160 amps 6500w ÷ 0.85 = 7647w 7647w ÷ 48v = 159 amps So we could call that 160 amps per unit... I think this is a conservative rating as the unit is...

Wouldn't crimping with a terminal do the same thing?

What's the trick to fitting 0 gauge wire on this breaker It's so close...
