Solis S6 6 kW 3 Phase Hybrid Inverter with DC – 2 MPPT for HV Batteries (WIFI/LAN)

The Solis S6 6 kW 3 Phase Hybrid Inverter with DC – 2 MPPT for HV Batteries (WIFI/LAN) is a transformer-less, IP66 power hub that blends 9.6 kW usable PV, high-voltage storage and seamless backup into a compact 600 × 500 × 210 mm aluminium chassis. Two independent MPPT trackers operate from 200 V to 850 V and accept 16 A each, enabling 160 % PV oversizing—ideal for roofs that can generate more power than the inverter’s nominal rating during winter or low-irradiance days.

Core electrical capability

PV input – 1 000 V DC max, 12 kW recommended array, 9.6 kW continuous to the inverter; MC4 connectors for rapid termination.

Battery interface – 120–600 V lithium; 6 kW / 50 A charge-discharge with closed-loop CAN/RS-485 control.

Grid output – 6 kW / 6 kVA at 3 N PE 400 V; handles 100 % phase imbalance and up to 50 % of rated power per phase—ideal for mixed single-phase loads.

Backup output – < 10 ms switchover, 6 kW continuous, 9.6 kVA surge for 60 s; THDv < 2 % keeps sensitive electronics stable.

Efficiency & protection

Max PV→AC efficiency 97.00 %; EU efficiency 97.10 %.

PV→battery round-trip 98.45 % and battery→AC 97.34 % reduce lifetime losses.

Integrated DC switch, reverse-polarity, PV over-voltage, battery reverse and Type II AC/DC surge arrestors; optional AFCI 2.0 arc protection.

Night self-consumption < 25 W preserves stored energy.

Smart-energy features

AI scheduler matches charge/discharge to time-of-use tariffs.

Native hooks for virtual-power-plant and EMS platforms.

Parallel firmware allows AC-coupled expansion or multi-inverter systems without external PLCs.

Built-in Bluetooth commissioning plus Wi-Fi/LAN connectivity feed live data to SolisCloud for remote diagnostics and firmware updates.

Mechanical & environmental

Weight 27.6 kg – single-person lift onto supplied wall bracket.

Natural-convection cooling keeps acoustic output below 46.9 dB.

Operates –25 °C to +60 °C; up to 4 000 m altitude; 0–95 % RH.

IP66 ingress rating ensures reliable outdoor or plant-room installation.

Installer benefits

160 % PV oversizing cuts inverter count and balance-of-system hardware.

Quick-plug AC and battery connectors slash onsite wiring time.

Screen-free design reduces ingress points; LED indicators give clear status, while the app provides full configuration.

Certified to IEC/EN 62109-1/-2, EN 50549-1, VDE 4105, G99 and other European grid codes for fast DNO approval.

The Solis S6 6 kW 3 Phase Hybrid Inverter with DC – 2 MPPT for HV Batteries (WIFI/LAN) delivers efficient solar harvest, rapid battery cycling and UPS-grade backup—giving installers a future-proof solution for smart, resilient three-phase self-consumption systems.
