Solis S6 15kW 3 Phase Hybrid Inverter

Three Phase Low Voltage Energy Storage Inverter

The Solis S6 Pro 15kW is a three-phase, low-voltage hybrid inverter purpose-built for three-phase South African properties homes, farms, small commercial premises, and light industrial facilities. Built on the S6-EH3P15K02-NV-YD-L platform, it delivers 15kW of continuous three-phase AC output with dual MPPT inputs, two independent battery ports totalling 290A of combined charge/discharge capacity, and a high 1,000V maximum PV open-circuit voltage for large-array compatibility.

With IP66 weather protection, NRS 097-2-1 certification, sub-10ms UPS switching, and support for up to 10 units in parallel, the S6 Pro 15kW is an ideal solution wherever three-phase power, high capacity, and reliable backup are all required.

15kW Three-Phase Output with Dual-MPPT Solar Input

• Rated Output: 15kW continuous three-phase AC output (3/N/PE, 380V/400V). Two independent MPPT inputs allow solar strings in different orientations or at different tilt angles to be managed separately, optimising energy yield across the full array even with complex roof configurations.

Max 24kW PV Array - 1,000V Max Voc

• PV Input: Accepts up to 24kW of solar input across 2 MPPTs (2 strings each, 4 strings total), with a maximum open-circuit voltage of 1,000V and an MPPT operating range of 200–850V. The elevated Voc ceiling supports longer string runs and larger array configurations compared to lower-voltage LV hybrid inverters.

Dual LV Battery Ports - 290A Combined Charge/Discharge

• Battery Compatibility: Two independent battery ports accept 48V nominal (40–60V) lithium-ion or lead-acid battery banks, with a combined maximum of 290A (150A per port) continuous charge and discharge. Dual-port architecture supports greater battery flexibility and higher system power throughput. CAN and RS485 battery communication supported.

Sub-10ms UPS Backup & 200% Overload Capacity

• Backup Performance: Transitions from grid to battery backup in under 10ms;  effectively uninterruptible for most sensitive loads. Delivers 200% of rated power (30kW) for 10 seconds in backup mode, enabling reliable three-phase startup of motors, pumps, compressors, and HVAC equipment.

Generator Integration, Peak Shaving & Parallel Operation

• Advanced Functions: Supports generator integration with automatic start/stop control across a wide generator input range (6–30kVA). Built-in peak shaving reduces maximum demand charges. Up to 10 units can be stacked in parallel for scalable three-phase systems (systems beyond 6 units require a Solis power distribution cabinet).

7-Inch LCD, Bluetooth & SolisCloud Monitoring

• Monitoring & Control: 7-inch LCD display with Bluetooth connectivity to the Solis Home app. CAN, RS485, and Ethernet communication support the SolisCloud platform for remote monitoring, AI-assisted energy optimisation, and fault diagnostics. Optional Wi-Fi, cellular, and LAN modules available.

IP66, NRS 097-2-1 & 5-Year Warranty

• Compliance & Protection: IP66 rated for full dust and water-jet protection. NRS 097-2-1 certified for South African grid connection. 5-year manufacturer’s warranty. Operating temperature: -40°C to +60°C. Dimensions: 430×660×295mm, 42kg.
