Product description

The Solis S6-EH3P12K-H-EU(21A) is a three-phase high-voltage hybrid inverter rated 12 kW, for residential and small commercial PV-plus-storage. It carries 4 MPPTs with up to 21 A input current per MPPT — suited to multi-orientation or partly shaded roofs and compatible with higher-power modules — and accepts PV input up to 160% of rated DC power (24 kW recommended array, 19.2 kW max usable) across a 200–850 V MPPT range, 1000 V max. The battery port is high-voltage (120–700 V) with 12 kW charge/discharge at up to 50 A over CAN/RS485. Grid output is 12 kW / 12 kVA at 380/400 V 3/N/PE, with three-phase unbalanced output (each phase up to 50% of rated power) for uneven loads. Backup transfers in under 10 ms and sustains a 160% overload for 60 s off-grid, starting motors, pumps and air-conditioning; a customizable backup reserve and PV-only off-grid mode are supported, and up to 6 units run in parallel to expand capacity. Max efficiency 97.85% (EU 97.51%, 98.31% battery-charged-by-PV). Rated IP66 for harsh outdoor conditions, −25 °C to +60 °C, natural cooling, <46.9 dB. Quick-connect plugs for battery and AC and MC4 for PV speed up install; monitoring and AI optimisation via SolisCloud over CAN/RS485 (Wi-Fi, cellular or LAN optional). DC Type II surge protection integrated (AC Type II optional), with integrated DC switch. Certified to EN 50549-1, VDE-AR-N 4105, G98/G99, IEC 62109-1/-2 and more. Dimensions 563 × 412 × 230 mm, 34.5 kg.
