The Solis RHI-3P10K-HVES-5G is a 10kW three-phase hybrid solar inverter built for high-voltage lithium battery systems, including the Pylontech Force H2. Running the battery bank at 500-600V rather than a conventional 48V cuts current through the circuit, which lowers cabling losses and lets the battery connection run without a fan. Maximum efficiency reaches 98.4%, and the unit includes dual MPPT tracking, AFCI arc-fault protection, and an intelligent energy management system.

Key features of this three-phase hybrid inverter

• Output, 10kW three-phase, for on-grid, off-grid, and backup operation
• Battery input, high-voltage DC, 500-600V typical, suited to Pylontech Force H2 and similar
• MPPT, 2 trackers with 4 DC inputs, up to 26A per MPPT
• AC backup, up to 10kW continuous, 16kVA peak
• Source switching, automatic transfer within 40ms
• Protection, integrated AFCI arc-fault detection

How the energy management works

The EMS coordinates PV, battery, grid, and load in real time, with three operating modes: self-consumption, time-of-use, and off-grid backup. On a time-of-use tariff it can draw from the battery when grid rates are high and recharge from the grid when rates drop, alongside standard peak shaving. The 40ms switching time keeps disruption to critical loads short when the source changes between grid, solar, and battery.

Applications

Aimed at commercial three-phase installations pairing solar generation with high-voltage battery storage, particularly where time-of-use optimisation or peak shaving is part of the design. It also suits larger residential or commercial systems built around Pylontech Force H2 or equivalent HV battery packs.

Installation notes

This is high-voltage DC equipment and must be installed by a qualified electrician or MCS-accredited solar installer, in line with BS EN 62619, IEC 62619, and local wiring regulations. Three-phase grid connection requires a G99 application and DNO approval. Cabling, isolators, and protection devices must be rated for the battery system voltage in use.
