just be cautious, my AIO sungrow battery output is not isolated from mains input so DC coupling might not work the way you want

That's not the point.. When the battery is disconnected from the inverter it's just a battery, it has no AC on it. no tingles, nothing measures 52VDC as you expect.. The issue is when it is connected, it still measures 52VDC but there's also about 110V to earth. (when measured across the...

Nothing on CEC website yet, but this would be good, I am looking to go with a Multiplus, but legal connection is a problem in Australia.

Measures 52V DC. As it should. There's definately AC there. It's enough to give a tingle / buzz. But I will replace the batteries in the meter anyway it's possibly time. The main thing I want to avoid is frying the MPPT when I connect it.

Hi all, I have a first generation Sungrow SH5K inverter - First generation meaning no firmware updates and limited functionality. it's almost 8 years old, so it has been a reliable system. I originally had it running a 48V lead acid battery, but now have a DIY LiFePO4 using Voltax 302Ah cells...

They're LiFePO4. 3.65 is not the resting voltage. All 4 batteries were charged before removing the cells from the casing, but in each battery there was a cell that reached HVC before the whole battery got to full charge. The other cells would have a pretty high SOC I imagine. It's all good...

Hey all... First post... I've got 16 X 300Ah cells pulled from a 12v battery module, the BMS wasnt doing much of a job in balancing, so I stripped the cells out and removed the BMS. In each battery module one cell was tripping HVC. My question is: When I parallel the cells to balance, what...
