Solis S6 12.0kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid - Without Display

• Manufacturer Solis
• Phases 3 Phase
• Inverter Type Hybrid Inverter

The Solis S6 12 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display combines high-voltage battery support, fast backup switching and AI-driven energy management in a single IP66 chassis. With four independent MPPT trackers and 160 % PV oversizing, the inverter lets designers connect up to 24 kW of modules yet still harvest 19.2 kW continuously—ideal for large residential or light-commercial roofs where winter yield matters.

Key performance highlights

PV input: 1 000 V DC max; MPPT window 200–850 V; 4 × 20 A input current; integrated DC isolator and optional AFCI 2.0.

Battery interface: 120–800 V lithium, 12 kW / 50 A charge-discharge, CAN / RS-485 closed-loop control.

AC output (grid): 12 kW / 12 kVA, three-phase 230 V; supports 100 % phase imbalance and delivers up to 40 % of rated power per phase; THDi < 3 %.

Backup port: < 10 ms switchover, 12 kW continuous, 1.6 × overload for 10 s; THDv < 2 % guarantees motor start stability.

Generator input: 12 kW / 30.1 A with auto-start contacts.

Smart-energy features

AI algorithms schedule battery cycling around time-of-use tariffs.

Native hooks for VPP and EMS platforms and built-in SG-ready heat-pump control streamline future upgrades.

Parallel firmware enables capacity expansion or AC-coupled retrofits without external controllers.

Commissioning via Bluetooth app; Ethernet standard, Wi-Fi or cellular optional.

Mechanical and protection data

IP66 aluminium enclosure, fan-cooled; operates –25 °C…+60 °C at up to 4 000 m altitude.

Dimensions 563 × 546 × 235 mm; weight 32.6 kg—one-person lift onto wall brackets.

Night self-consumption < 25 W preserves battery charge.

Safety suite includes anti-islanding, DC reverse polarity, battery reverse, PV over-voltage, short-circuit and Type II AC/DC surge protection.

Installer benefits

MC4 PV connectors and OT terminals for AC and battery minimise on-roof wiring.

0-display design reduces penetration points; LED status plus app keep diagnostics simple.

160 % PV oversizing, phase-unbalanced output and generator port give unmatched design flexibility.

Meeting EN 50549-1/-10, VDE 4105 and IEC 62109-1/-2 standards, the Solis S6 12 kW 3 Phase Hybrid Inverter for HV Batteries, LV Grid – Without Display is ready for European DNO approvals out of the box.

By deploying this inverter, installers deliver seamless whole-site backup, tariff-aware battery management and future-proof integration—all from a single, compact unit.
