This Off-Grid type All-in-one ESS Battery with Inverter combines a 5KWh/10KWh energy storage battery and an off-grid AC 230V 5kw inverter. The battery module is a lithium iron phosphate battery (LiFePO4 technology) with high safety and high reliability. The output voltage for the pure sine wave inverter is AC230V, and it can support photovoltaic access at the same time, very convenient for users to install and maintain.
