Solis Inverter S6 15kW Three-Phase LV Hybrid 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.
