Hey doc. I’ve also got two 40 what EPEVER 40 w solar charge controllers.

Which investor should I use. Now I’m completely confused. Do I need more pv panels or batteries. I’ve got a set of 4 lifepo4 200 ah cells. Can I use these along with my 16 90 ah lifepo4 cells. I can put more panels in but ordering more cells from China concerns me with what alls going on there...

I’ve still got it. acdoctor. The older SCC the one in the picture will use 12 volts through 96 volts. 120 volts. I have provided a picture of the spec. I’ve sent a text to the eBay seller to see if they will exchange it for one I can use. Sir what would you suggest. Alan

So what do I need to. Do I have to install more panels? Or more batteries

I know this is over built but I didn’t really have a need to do it. I started buying equipment. But I have a shed that doesn’t have ac power. So I decided to put my solar project in the shed. Mainly I need power every now and then. Allot of our lawn tools used A/C. Also I’ll use a sump pump to...

No I have a SPF 3500 ES. What is a 3000TL?

If your correct about the European ground what will that mean for me

ACDoctor, I think after seeing the advice you and the forum provided I think 4 panels in series will be ok. Maddy to answer your question of how I came up with the idea of 4 in series would be over voltage, now I have no idea. But with your help and me rethinking it though again I can see your...

The problem is my lack of know how. But I’m trying. Thanks to the forum I might get this correct

450 VOC

Inverter growatt SPF 3500 ES, has a limit of pv voltage of 450 volts. Max Amperage input is 18a. Max charge current 80a. 4 pv panels. 305 watts each growatt spf 3500 ES. I have 4 pv panels. 305 watts, max voltage 36.8, current 8.30 amps, VOC 45.6.

Yes sir. I’ve purchased a growatt 3500 inverter 48 volts. With four panels in series I’m over voltage. With 2 in series and 2 parallel. I’m over amped. With the 4 panels, I want 3 panels in series and 1 panel in parallel. That configuration will be just right as for the V and amps for my...

Your suggestion is appreciated. But that would over amp the system and I would be over voltage. I have four panels. I want to hook 3 in series and 1 panel in parallel. I have a48 volts system

I’ve got 4 panels. Thanks for your help

I’ll have 3 in series and 1 in parallel.
