ST-BJ single phase hybrid grid solar inverter delivers pure sine wave output with seamless grid interaction, maximizing self-consumption and lowering electricity bills. Advanced CPU control and high-precision SMT ensure outstanding reliability and reduced after-sales costs for distributors. Users can switch between Utility, Eco, and Battery modes while the LCD touch display and WiFi remote monitoring via the NASCCLamp app enable complete energy management. Integrated overload, short circuit, and over-temperature protection with automatic alarms safeguards against downtime, making it an adaptable, low-maintenance solution for residential grid-tied systems.
The ST-BJ series 4-6kW single phase hybrid inverter delivers 97.5% max efficiency with SiC technology, supporting off-grid operation, dual battery branches, and wide grid compatibility. Below are the core technical parameters for your reference.
