The Solis S6-EH1P3K-L-PLUS is a compact and versatile 3kW single-phase low-voltage hybrid inverter designed for residential photovoltaic and battery-storage systems. It combines solar generation, battery management, backup power and smart energy control in one flexible platform.

Part of the Solis SOLARATOR Series, the inverter supports both lithium-ion and lead-acid batteries operating between 40 and 60V, providing broad compatibility with low-voltage storage solutions. The 3kW model supports up to 3kW battery charge/discharge power and a maximum charge/discharge current of 70A.

On the PV side, the inverter supports a recommended solar array size of up to 6kW, while the maximum usable PV input power is 4.8kW. Two independent MPPT trackers, a 90–435V MPPT range and a maximum input voltage of 500V allow flexible string configuration and efficient solar harvesting.

For backup applications, the S6-EH1P3K-L-PLUS switches between grid and backup operation in less than 10ms, helping maintain continuous power to critical loads. In off-grid mode, it can provide up to 200% of rated power for 10 seconds, supporting the startup of demanding appliances such as pumps, motors and air conditioners.

The inverter also supports generator integration, smart-load management, PV-only off-grid operation and parallel connection of up to six units for increased system capacity. A large 7-inch LCD display, Bluetooth and app connectivity provide convenient local operation and monitoring.

With IP66 protection, natural cooling and an operating temperature range from −25°C to +60°C, the S6-EH1P3K-L-PLUS is built for reliable residential energy management in a wide range of environments.
