Solis S6 5kW 3 Phase Hybrid Inverter with DC - 2 MPPT for HV Batteries (WIFI/LAN)

• Manufacturer Solis
• Phases 3 Phase
• No. of MPPT 2

The Solis S6 5 kW 3 Phase Hybrid Inverter with DC – 2 MPPT for HV Batteries (WIFI/LAN) is purpose-built for small commercial and large-residential projects that need high-voltage battery storage on a 400 V three-phase grid. Two independent MPPT trackers accept strings from 200 V to 850 V and allow 160 % PV oversizing, letting designers connect up to 10 kW of modules yet harvest 8 kW continuously. With a transformer-less topology and natural-convection cooling, the inverter delivers 96.5 % peak efficiency and night self-consumption below 25 W, maximising lifetime yield.

PV & battery architecture

1 000 V DC maximum input, 16 A per MPPT, MC4 connectors for fast termination

High-voltage lithium interface (120–600 V) charges and discharges at 5 kW / 25 A with closed-loop CAN/RS-485 control

98.4 % PV-to-battery and 97.3 % battery-to-AC efficiencies reduce round-trip losses

AI engine schedules charging and discharging around time-of-use tariffs and integrates with VPP/EMS platforms

Grid, backup & quality

5 kW / 5 kVA export at 3/N/PE 380/400 V; supports 100 % phase imbalance and up to 50 % of rated power per phase – perfect for mixed single-phase loads

Backup port supplies 5 kW continuous with 8 kVA surge for 60 s; < 10 ms switchover keeps IT and heat pumps online

THDi < 3 % (grid) and THDv < 2 % (backup) protect sensitive electronics

Protection & compliance

Built-in DC switch, reverse-polarity, PV over-voltage, battery reverse and Type II AC/DC surge arrestors

Optional AFCI 2.0 arc detection for rooftop fire-risk mitigation

Certified to IEC 62109-1/-2, EN 50549-1, VDE 4105, G98/99 and other EU grid codes

Mechanical design

Compact 600 × 500 × 210 mm IP66 aluminium enclosure; 27.6 kg single-person lift

Operating window –25 °C to +60 °C, 4 000 m altitude, noise < 46.9 dB

Quick-connect AC and battery plugs shorten onsite wiring; Bluetooth app completes commissioning in minutes

Standard Ethernet plus Wi-Fi/LAN dongle provide remote firmware updates and SolisCloud monitoring

Installer advantages

Two-MPPT architecture suits rooftops with east-west or unequal string lengths

160 % oversizing cuts levelised cost of energy and reduces inverter count per project

Grant-ready safety suite and screen-free design lower failure points and speed DNO approval

The Solis S6 5 kW 3 Phase Hybrid Inverter with DC – 2 MPPT for HV Batteries (WIFI/LAN) gives installers a robust, tariff-aware solution that blends solar, high-voltage storage and UPS-grade backup into one IP66 package—ideal for customers who demand reliability and future-proof scalability.
