Solis S6 15kW 3 Phase Hybrid Inverter with DC - 4 MPPT for HV Batteries (WIFI/LAN) - Without Display

Engineered for large residential and small-commercial jobs, the Solis S6 15 kW 3 Phase Hybrid Inverter with DC – 4 MPPT for HV Batteries (WIFI/LAN) – Without Display gives professional installers the flexibility to handle oversized PV, high-voltage storage and demanding three-phase loads in one IP66-sealed package. Four independent MPPT trackers accept 30 kW of modules and harvest up to 24 kW DC continuously, while the battery port moves 15 kW charge or discharge at 120–800 V HV—plenty of headroom for today’s liquid-cooled packs. ​

Installer-driven power electronics

True three-phase hybrid: delivers 15 kW / 15 kVA to the grid and supports 100 % phase imbalance and half-wave loads—ideal for UK sites with uneven consumption. ​

UPS-grade backup: dual backup ports supply critical and non-critical boards with < 10 ms switchover and 1.6 × rated power for 10 s to start heavy motors. ​

Generator-friendly input: automatic voltage-sense prevents reverse feed and lets you extend autonomy during long outages.

Peak-shaving & SG-ready: built-in EMS schedules battery cycling to flatten demand charges and drive Smart Grid heat pumps.

High-yield, low-noise design

One-visit commissioning

Front DC isolators & MC4 inputs cut roof wiring.

OT terminals for battery and AC save gland time.

LED indicators + Bluetooth app replace the front LCD, reducing penetrations and failure points.

SolisCloud remote diagnostics, firmware pushes and export-limiter settings via Ethernet, Wi-Fi or RS-485.

Commercial upside for EPCs & electricians

160 % PV oversizing means you can quote larger arrays than competitor hybrids, driving module revenue without extra inverter SKU.

Unbalanced load support eliminates expensive load-split panels and keeps customers’ single-phase EV chargers on a three-phase supply.

Generator integration and dual backup ports translate into lucrative rural and light-commercial upsells.

10-year warranty, G99-certified firmware and European spares hub keep O&M risk low and margins predictable.
