Yes. 2 serial and 4 in parallel. web page states "4P2S" for a max of 30.72 Kwh. There are laser welds.. not sure I want to do a dissection and resurrection.

You are correct. I will edit my post.

I am upgrading from a growatt 24v inverter to an eg4 6000xp 48v inverter. I've order 1 48v EG4 LL battery ( 100ah) as well. My current system consists of two 150AH 24v batteries in parallel ( 300AH). I want to serialize these into a single 150AH 48v battery, then put the EG4 battery ( 100AH)...

I can't add these to my current strings. I would need to make a new string, but I'm not ready yet. Keep me in mind -- I have another charge controller I'll be adding once I get the two I just bought installed. Thanks for posting these.

It was already set. I think user ( was user2) amd setting both voltages to 27.4 is what fixed it.

I have it dialed in now

Are you using lifepo4 batteries and 'user 2' on the growatt 3000?

So Solar/Battery/Utility is not really solar first. It does not use solar first -- it uses Battery if it's above the 'float' voltage, and only pulls solar if it trying to charge the battery.

Understood.. but why won't the growatt AIO switch to solar when there is an AC load? At the end of the day, my battery is down 10 or 15 percent, even.though the sun has been out all day. I would expect the day to end with a larger charge.

I have a growatt 3000 SPF LVM with 6.5 KHW battery. I have my inverter set to 'Solar/Battery/Utility' but when my battery hit's 100%, I don't think it's trying to pull any solar, because it reports '0 W' solar PV on solar assistant. Does it draw on the battery and not use solar when the...

I also live in Clayton. I am interested. Six would be perfect.

What panels are recommended for a growatt 3000 24v which has voc of 145 and mppt of 125? Currently, I have six 175w panel form renogy ( 3s2p ), but I am thinking of adding a second growatt 3000 for split phase ( to support my well pump). I'd rather go with another vendor which may be...

I've added a new battery to my 24v solar charger/inverter, and I have two weize 12v 100ah batteries. I'm considering tearing the batteries apart to create a 24v battery with a smarter BMS. I've seen the teardown by Will Prowse and believe the batteries to be welded to the bus bars, so I need...
