Solis S6 15 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display

The Solis S6 15 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display extends the proven S6-EH3P platform to larger self-consumption and backup projects. Designed around four independent MPPT trackers and a high-voltage (120–800 V) battery port, the unit couples up to 1 000 V DC of solar with low-voltage (3 × 230 V) grid output, delivering seamless energy management for farms, small businesses and prestige homes.

PV and battery architecture

1 000 V DC absolute input voltage; MPPT window 200–850 V for flexible string design

Four 20 A inputs handle today’s high-current bifacial and n-type modules

160 % PV oversizing capability maximises yield during low-irradiance months

High-voltage lithium interface (120–800 V) charges and discharges the battery at up to 50 A, controlled via CAN / RS-485 closed-loop communication

Grid, backup and generator support

Three-phase 133 V / 230 V output with 100 % phase-imbalance tolerance—ideal for mixed single-phase loads

Sub-10 ms transfer time keeps IT, lighting and heat pumps energised during outages

Built-in generator input accepts automatic two-wire start/stop commands for extended autonomy

Harmonic distortion kept within < 3 % (THDi) on grid output and < 2 % (THDv) on backup output, protecting sensitive equipment

Smart-energy functions

AI scheduling charges and discharges the battery according to time-of-use tariffs

Native hooks for virtual-power-plant and EMS platforms enable revenue stacking

SG-ready heat-pump relay and zero-export control ship as standard

Bluetooth app commissioning plus Ethernet connectivity; Wi-Fi or cellular optional

Installation advantages

MC4 connectors for PV and OT lugs for AC / battery speed first-fix wiring

Parallel firmware allows future inverter or AC-coupled PV expansion without external PLCs

Display-free design reduces ingress points; LED indicators and the mobile app provide clear status and fault codes

All certifications—IEC 62109-1/-2, EN 50549-1/-10, VDE 4105—are in place for straightforward DNO approval

With high-voltage storage, rapid backup switching and advanced tariff optimisation in a single IP66 enclosure, the Solis S6 15 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display gives installers a robust, future-proof solution for large three-phase solar-plus-storage projects.
