Note: The cheaper of SolarMax's two 1.28 kWh units, and the difference is in the case and the life rather than the capacity. ABS instead of metal, floor standing only, 3500 cycles against 6000, and a one year product warranty against three. Same cells, same Bluetooth, same 100 A ceiling. Worth comparing the price gap against the cycle gap before choosing: 3500 cycles is roughly half the service life for the same stored energy. The datasheet states no IP rating.
