Solis 15kW Three Phase Hybrid Inverter

This 15kW three-phase hybrid inverter — the Solis S6-EH3P15K — is the highest capacity in Solis's low-voltage three-phase series, built for properties with the highest power demands that still want the flexibility and lower cost of a low-voltage (40–60V) battery system rather than stepping up to high-voltage lithium. It supports up to 24kW of usable PV input across dual MPPT trackers, and a max charge/discharge current of 290A — the highest battery throughput in this series.

It shares the same core reliability features as the 12kW model — dual backup ports for critical/non-critical load control, under-10ms backup switchover, 200% overload capability for 10 seconds, and support for unbalanced and half-wave loads across both grid and backup ports. Multiple units can combine to form a microgrid, and generator connectivity extends backup during longer outages. Running at up to 97.6% max efficiency and IP66 rated, 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 15kW is the right capacity, or request a quote for current pricing.
