Solis S6 10kW 1 Phase Hybrid Inverter with DC - 2 MPPT for LV Batteries
SKU: S6-EH1P10K-L-PLUS
The Solis S6-EH1P10K-L-PLUS (21A) is a 10kW single-phase, low-voltage (40–60V) hybrid inverter designed for larger residential and light commercial systems needing high PV input capability, strong battery performance, and reliable backup. It features 2 MPPTs with support for up to 21A PV input current (future-proofing for modern high-current modules), <10ms on/off-grid switching, 200% overload for 10 seconds in off-grid mode, generator integration, and parallel expansion up to 6 units.

The Solis S6 10kW 1-Phase Hybrid Inverter (S6-EH1P10K-L-PLUS 21A) is built for high-output self-consumption and backup applications, combining flexible PV design, LV battery compatibility, and robust off-grid behaviour in one platform.
PV input (2 MPPT – high current, oversizing supported)
The 10kW model supports substantial PV capacity, with a recommended max PV array size of 20kW and max usable PV input power of 16kW. It operates with 2 MPPTs / 4 strings, offering a wide MPPT range of 90–435V (start-up 90V, max DC 500V, rated 330V) for versatile stringing. It also supports up to 21A PV input current (model variant noted as 10K(21A)), helping with compatibility for newer, higher-current module formats.
Low-voltage battery storage (40–60V) with high power charge/discharge
Designed for low-voltage batteries (40–60V) including Li-ion and lead-acid, the inverter supports CAN / RS485 comms. On the 10kW model, battery performance scales to 10kW max charge/discharge power and up to 210A charge/discharge current—ideal for high-demand homes, small businesses, and backup-critical installations.
Backup power that can start heavy loads
For outage operation, the S6 hybrid platform offers:
<10ms backup switchover
2× rated apparent power for 10 seconds (backup overload)
Stated 200% overload for 10s in off-grid mode, supporting motor starts (pumps, air con, etc.)
Smart load management and a customisable battery backup level to extend runtime for critical circuits
Generator and system expansion options
The inverter supports generator input (up to 10kW on the 10kW model) with multiple connection methods and auto control options, enabling flexible backup strategies. For larger systems, it supports parallel operation up to 6 units, allowing scalable capacity growth.
