I'm working on the design of my residential solar system. The Growatt SPH 6000 seems like a good fit. I'm aware of the service issues and I'll be getting from a local supplier that will enable warranty claims directly to him under the local jurisdictions (I'm in Bulgaria). All other options cost twice and over, so I'm likely going for it.
The question that I'm unable to answer is can I use It with a custom LiFePo4 16S battery (EVE 160Ah cells) and what are the drawbacks if the battery BMS doesn't communicate with the inverter.
In the manual, I see that I can adjust a few parameters for lead-acid batteries that are likely to enable the use of LiFePo4 batteries. There are CV, LV, and CC params. If I'm correct these are max charging voltage (CV) battery cut out voltage (LV) and max charging current (CC).
What would be the drawback if I use a 16S LiVePo4 battery configured as lead-acid with CV of 56V (3.5V per cell), LV of 48V, and CC of 60A. The PV power will be at most 3000W, so 60A charging current is unlikely to be a problem. The voltages are a bit on the safe side, but I'll try to cycle the SOC from 10% to 90% with a goal to extend the battery life.
