Product Title

Solis S6-EH1P6K-L-PLUS 6kW Single-Phase Low-Voltage Hybrid Inverter

Short Description

The Solis S6-EH1P6K-L-PLUS is a 6kW single-phase hybrid inverter for residential and light-commercial solar energy-storage systems. It combines dual MPPT solar input, 40–60V lithium-ion or lead-acid battery compatibility, 6kW backup output with under-4ms transfer, generator support, IP66 protection and a 7-inch LCD with Bluetooth app access.

Long Description

Designed for flexible solar generation, battery storage and backup power, the Solis S6-EH1P6K-L-PLUS integrates grid-connected operation and dependable backup functionality in one weather-resistant enclosure. Its two independent MPPT trackers support up to 9.6kW of usable PV input, while the low-voltage 40–60V battery interface delivers up to 6kW and 135A charge/discharge capability.

During a grid interruption, the dedicated backup output transfers in less than 4ms and can provide 200% of rated apparent power for 10 seconds, helping support demanding inductive loads. Generator input, AC-coupling capability, smart-load functions and parallel operation make the inverter suitable for new installations and energy-storage upgrades.

The IP66 enclosure supports indoor or outdoor installation, while natural-convection cooling reduces routine fan maintenance. A 7-inch LCD, Bluetooth app interface and RS485/CAN communications provide clear system control and battery integration. Optional Wi-Fi, GPRS and LAN monitoring interfaces are supported.
