Skip to content The ST-GP Series is a high-frequency off-grid pure sine wave inverter designed for demanding residential, commercial, and industrial applications. Available in 8.2kW and 10.2kW models, this inverter features dual independent MPPT solar charge controllers, supporting two photovoltaic inputs for higher energy harvest. It delivers 99.9% MPPT efficiency, operates with multiple battery types (including lithium with EMS communication), and offers time-of-use charging/discharging to reduce electricity costs. Built with comprehensive hardware and software protections, the ST-GP Series is a reliable choice for off-grid sites, rural factories, telecom towers, and large homes across Southeast Asia, Africa, South America, and the Middle East.
The ST-GP-48 series 8.2kW-10.2kW single-phase off-grid solar inverters employ dual independent MPPT charge controllers, supporting off-grid operation. The following are its core technical parameters for your reference.
