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
