Solis S6-EH3P(30-50)K-H 30/40/50kW Three Phase High Voltage Hybrid Energy Storage Inverter | Commercial PV Storage Inverter with 4 MPPT, 200% PV Oversizing & Generator Support

The Solis S6-EH3P(30-50)K-H series covers 30kW, 40kW and 50kW power ratings, a professional high-voltage three-phase hybrid inverter designed exclusively for commercial & industrial solar energy storage systems, integrating grid-connected PV generation, high-voltage battery storage, emergency backup power and generator coupling in one robust unit.

Built with IP66 full outdoor waterproof and dustproof enclosure, this hybrid inverter adopts a 4-MPPT architecture supporting 8 PV strings with 20A per string, compatible with modern high-power bifacial solar modules. It allows up to 200% PV oversizing to fully maximize rooftop solar yield and boost self-consumption rate, with maximum conversion efficiency reaching 97.8%.

Two independent high-voltage battery ports are equipped, supporting a total max charge/discharge current of 140A (70A per channel), wide battery voltage range 150–800V, and compatible with mainstream high-voltage lithium battery modules from 100Ah to 280Ah for flexible capacity expansion and lower system cost.

It realizes UPS-level seamless on/off-grid transfer within <10ms to guarantee uninterrupted power for critical industrial loads. The off-grid backup port provides 160% short-term overload capacity for 2 seconds, stably starting heavy inductive loads such as air compressors, water pumps and production machines. It fully supports three-phase unbalanced loads and half-wave loads, plus a dedicated generator input port to extend backup runtime during long grid outages, with both self-use and generator peak-shaving modes available.

For large-scale commercial energy storage expansion, up to 6 inverters can be paralleled together to form a combined system up to 300kW, meeting the power demand of medium and large factories and commercial complexes. A 7-inch industrial touch LCD screen is embedded for local parameter setting and real-time status monitoring, paired with Solis Cloud remote monitoring via WiFi/4G cellular modules for 24/7 intelligent operation, fault diagnosis and TOU peak-valley arbitrage control.

Comprehensive multi-layer safety protections including DC arc fault protection, surge protection, overcharge/over-discharge protection and anti-islanding protection are standard. With stable performance, strong expandability and flexible multi-scenario adaptability, the Solis S6-EH3P(30-50)K-H becomes the optimal high-capacity hybrid inverter solution for commercial peak shaving, new energy matching, industrial backup power and off-grid microgrid projects worldwide.
