Solis 20kW Three Phase High Voltage Hybrid Inverter

This 20kW three-phase hybrid inverter — the Solis S6-EH3P20K-H — steps into Solis's high-voltage line, built for large residential and small commercial properties with serious power demands. Unlike the low-voltage models in Greenvion's range, this is a high-voltage, lithium-only battery system (120–800V) — a different, more advanced battery architecture than the 40–60V low-voltage line, worth confirming with our team before committing if you're comparing against a lower-capacity low-voltage model.

With 4 MPPT trackers accepting up to 20A each and supporting up to 32kW of usable PV input, it's built for large or complex roof layouts with multiple orientations. It runs at up to 97.7% max efficiency with 99.9% MPPT tracking efficiency, switches to backup power in under 10ms, and can operate as a grid-tied inverter without a battery at all if you want to phase in storage later. Smart features include SG heat pump compatibility, VPP and EMS platform integration, and AI-driven battery charge/discharge management based on time-of-use tariffs. Up to 6 units can be paralleled for genuinely commercial-scale capacity. Every unit Greenvion sells is warranty-backed, and our EPRA-licensed team can install and configure it as part of a complete solar system — book a free site assessment to confirm whether 20kW high-voltage or a lower-capacity low-voltage system fits your property better, or request a quote for current pricing.
