Solis S6 20kW 3 Phase Hybrid Inverter with DC - 4 MPPT for HV Batteries (WIFI/LAN) - Without Display

The Solis S6 20 kW 3 Phase Hybrid Inverter with DC – 4 MPPT for HV Batteries (WIFI/LAN) – Without Display is the highest-power model in Ginlong’s S6-EH3P range, purpose-built for large residential clusters, farms and light-commercial rooftops that demand serious PV oversizing, fast high-voltage storage and seamless backup. Four independent MPPT trackers each accept 1 000 V / 20 A, letting you connect up to 40 kW of modules and harvest 32 kW DC in real time for maximum winter output. ​

Performance that pays

True three-phase hybrid – exports 20 kW / 20 kVA to the grid while tolerating 100 % phase imbalance; no costly load-balancing panel required. ​

Heavy-duty battery port – charges or discharges at 20 kW (50 A) on 120–800 V lithium packs, ready for premium liquid-cooled stacks and VPP contracts. ​

UPS-grade resilience – transfers to backup in < 10 ms and surges to 32 kVA for 10 s, starting 4 kW heat pumps or 11 kW compressors without tripping. ​

Efficient by design – 97.7 % peak / 97.5 % EU conversion, 98.5 % PV-to-battery, and < 25 W night draw keep more kilowatt-hours billable. ​

Installer-friendly features

Front DC isolators, MC4 inputs and OT lugs slash first-fix time.

LED indicators + Bluetooth app replace a vulnerable LCD, cutting penetrations while keeping commissioning simple.

Generator input sensing prevents reverse feed and extends backup autonomy for rural estates.

IP66 aluminium body, smart-fan cooling (< 65 dB) and –25 °C … +60 °C rating suit UK barns, plant rooms or wall-mounted outdoor installs. ​

Commercial upside

160 % PV oversizing boosts module sales without extra inverter SKUs.

SG heat-pump and peak-shaving support create lucrative cross-sell opportunities.

SolisCloud remote diagnostics shrink O&M site visits and safeguard SLA margins.

10-year warranty & G99 certification reassure DNOs and finance partners alike.
