Thanks Gerlach I’m nearly persuaded. Now all I need is to make decision on Li batteries: Pylontech, SolarMD ??? 🤯

On the WRND MPPT I can adjust float volts, current limit, equalize voltage (also duration and frequency), boost voltage (also duration), boost equalize end amps, and PV 60.0Vmp. The MLT Nomad MPPT looks like it would make things simpler

I have To replace my old bank of batteries (Dixon 105Ah - 3 string of 4). I was thinking of getting the Pylontech US3000 3.5kWh (hoping to get away with 2). I have 2 x MLT Oasis 448 inverters (working in parallel) and believe the batteries will work with them. However, I’ve been told that my WRND Proseries 48 (150V, 120A) might not work properly with the Pylontech. Can this be so? If so, why? What do I need to know about MPPTs charging lithium batteries? I know WRND does not have a great reputation, but I have not noticed any problems with it and don’t want to spend on a replacement if I don’t have to. any advice?

Pylontech 3000

Thanks for the pointers and advice. Much appreciated. I have been quoted R147 k for 6 x Pylontech Lithium-ion batteries (is that reasonable?) Are these quite distinct from LiFePO4 batteries What kind of lifespan do they have?

I’m learning the expensive way and don’t want to repeat my mistakes. 2.4 kw panels, 2 x MLT Oasis inverters, bank of 12 Dixon 105Ah batteries. After 33 months apparently the batteries are shot and need replacing. Each each inverters serve different parts of the house which have separate distribution boards. In nearly three years I haven’t noticed any savings on my electricity bill. I’m looking for someone to properly evaluate the installation of my system and advise on batteries. I live in Hilton KZN, but the only experts I can find seem to be hack battery salesmen in a hurry. Any recommendations?
