Product Title

Solis S6-EH1P8K-L-PLUS 8kW Single-Phase Hybrid Inverter IP66

Short Description

The Solis S6-EH1P8K-L-PLUS is an 8kW single-phase, low-voltage hybrid inverter designed for residential solar-plus-storage systems. It supports 40–60V lithium-ion or lead-acid batteries, two MPPTs with four PV string inputs, an 8kW backup output, generator and AC-coupling functions, IP66 protection, and local control through a 7-inch colour display and Bluetooth app connection.

Long Description

Built for flexible residential energy storage, the Solis S6-EH1P8K-L-PLUS combines an 8kW grid output with an 8kW battery charge/discharge stage and a dedicated backup output. Its two MPPT trackers accept up to four PV strings, while a maximum usable PV input power of 12.8kW allows a 1.6 DC-to-AC ratio for stronger solar harvesting across changing conditions.

The inverter works with compatible 40–60V lithium-ion and lead-acid batteries and supports up to 190A charge/discharge current. A dedicated smart port can be configured for a generator, smart load or AC-coupled grid-tied inverter. Backup transfer is rated below 4ms, and the backup output can supply twice rated power for 10 seconds to accommodate demanding starting loads.

For system management, the S6 platform provides a 7-inch colour LCD, built-in Bluetooth, RS485 and CAN communication, with optional Wi-Fi, GPRS or LAN monitoring through SolisCloud. Its IP66 enclosure, intelligent cooling and comprehensive electrical protections make it suitable for indoor or outdoor installation when installed in accordance with the official manual and local regulations.
