   I received the product in March and so far so good!
   I got 22kWh of LiFePo4 batteries and the only complain is that from time to time it looses connection with them (I get the error 61). The battery Seplos BMS does not communicate with the inverter. Obviously. the battery manufacturer says that there is an issue with the inverter insufficient RAM memory.
   I have two photovoltaic panels strings of roughly 8.6kW, but I cannot “order” more sun during the winter cloudy days. Obviously the real power is less and the Voc < 450V AC.
   Other than that, it is working great for the price. It is covering the house consumption with no issues. Now I am thinking if to buy another one just the same, and put it in parallel. The alternative is to buy a newer model and extra panels (at least another 4kW. The idea is that one device will power the house while the other will only charge the batteries.
   Soon I will complete a DIY battery 15kWh with a different BMS (Apexium) and I am curios to see if this one will communicate better with the inverter.

     Thanks for your feedback. Seplos is NOT a recognized protocol MPP Solar inverters support (we support Pylontech, Weco, Soltaro, or batteries that adopt MPP Solar protocol – which they can apply the “LIB” setting) so that may explain why you’re having difficulty using BMS to communicate with it. I don’t think RAM is an issue as we don’t have this issue when working with supported BMS protocols. If you have further questions relating to the use of BMS, feel free to reach out to MPP Solar support (support@mppsolar.com). thank you.
