Solis S6 HV 125kW 3 Phase Hybrid HV Inverter

The Solis S6-EH3P-125K10-NV-YD-H 125kW Three-Phase Hybrid Inverter

The most advanced large-scale C&I energy storage technology brings Solis' technology to Southern African commercial and industrial installations. Designed to manage 125kW of three-phase output alongside high-voltage battery storage and a solar array of up to 250kW, it gives factories, warehouses, agri-businesses, and data centres an intelligent, scalable tool to eliminate Eskom dependency and take control of peak-demand costs at scale.

Key Features & Specifications:

Ten Independent MPPTs with 2× PV Oversizing

Ten dedicated solar trackers independently optimise energy harvest from large commercial arrays. With support for up to 250kW of PV input and a 21A max string current compatible with high-power commercial modules, the S6-EH3P-125K10-NV-YD-H accelerates daily battery charging and maximises solar self-consumption.

Dual High-Voltage Battery Ports (200A Total)

Two independently controlled battery connections deliver a combined 200A charge/discharge current, with compatibility across 100–314Ah HV battery modules. Independent ports allow flexible configuration and easy capacity expansion, reducing total system costs over the installation's lifetime.

Sub-10ms Backup with 200% Overload Capacity

On-to-off-grid transition in under 10ms keeps critical equipment and production processes running through loadshedding. The backup port delivers 2.0 times rated power for short durations handling the start-up surge of large motors, HVAC compressors, and industrial machinery.

Generator & Multi-Source Integration

A versatile three-in-one input interface accepts on-grid PV, wind, and diesel generator sources with battery reserve management and intelligent load prioritisation; ensuring critical loads stay powered through extended outages and weak-grid scenarios.

Parallel Scalability up to 750kW+

Up to six units operate in parallel for a combined 750kW output, with further expansion toward 1.25MW using the Solis STS cabinet; making the S6-EH3P-125K10-NV-YD-H the right long-term platform for Southern Africa's most demanding C&I energy storage projects.

SolisCloud Commercial Monitoring

SolisCloud delivers AI-optimised remote management, peak-shaving control in self-use and generator modes, dynamic reactive power compensation, instant fault diagnostics, and real-time generation and consumption data; all from anywhere.

Patented Cooling Technology for All-Weather Reliability

Proprietary thermal management ensures reliable operation under Southern Africa's high ambient temperatures and demanding industrial conditions; keeping the inverter performing optimally during continuous heavy commercial loads.

Warranty Protection:

• 5-year standard product warranty
• 10-year extended warranty available — purchasable via the SolisCloud app or through your authorised Solis distributor
• T&C may apply.

For large commercial buildings, industrial facilities, agri-businesses, and demanding C&I installations that need scalable, intelligent battery storage at the 125kW scale, the Solis S6-EH3P-125K10-NV-YD-H Three-Phase Hybrid Inverter is the purpose-built solution. Compatible with a broad range of high-voltage battery systems and scalable to 750kW and beyond.
