There are 2 models of LG Chem, the low voltage LV model which is 48 volts and the high volume HV model which is 400 volts. LG do not make inverters so you need to rely on a third party inverter for managing the charging and controlling of the battery. This has its advantages and disadvantages, as it gives you choice of inverters, whilst also providing challenges at the same time with communications and after sales service issues. LG manufacture the cells in house and the unit is Korean made to high quality standards.
LV; The LV model is compatible with Sungrow and Goodwe inverters, and is the most popular model, due to the cheaper price of the inverters.
HV; The HV model is compatible with SMA, SolarEdge and Fronius. The cost of the batteries is significantly higher than the LV model and combined with these inverters is a larger price than most other products on the market.
