• Range Solis PrimePower
• Manufacturer Solis

The Solis PrimePower 109kWh + C5 Combo - Expandable Master- Standard Version + C5 - Includes All Standard Model Items, C5 Environmental Protection and S6-EH3P50K-H combines a high-capacity battery cabinet with a 50kW three-phase hybrid inverter into a single, pre-engineered commercial storage system. With 109.7kWh total energy and around 98.7kWh usable, this all-in-one package is ideal for C&I sites looking to cut peak demand, maximise PV self-consumption and improve resilience.

As an integrated battery storage and inverter platform, it allows installers to deliver bankable, repeatable energy storage projects without having to design every element from scratch.

PrimePower Integration and Operation

At the heart of the system is the S6-EH3P50K-H hybrid inverter matched to the PrimePower battery cabinet. Together they provide:

50kW three-phase AC power for charge, discharge and backup

Up to 96kW PV input with four MPPTs for flexible string design

Fast transfer from on-grid to off-grid in under 10ms to protect critical loads

The Solis PrimePower 109kWh + C5 Combo - Expandable Master- Standard Version + C5 - Includes All Standard Model Items, C5 Environmental Protection and S6-EH3P50K-H is engineered as an “Expandable Master” unit, forming the core building block of larger commercial storage systems up to 500kW / 6.5MWh through parallel cabinets and inverters.

High-Performance Battery Technology

The PrimePower cabinet uses LFP cells from CATL (306Ah) arranged in a 1P112S configuration with seven 15.67kWh packs. This delivers robust cycle life (up to 10,000 cycles under manufacturer test conditions) and a 0.5C charge/discharge rate suitable for most C&I profiles.

For your customers, that means a long-lived storage system with predictable performance and strong round-trip efficiency. For installers, it provides a standardised battery storage platform from a leading global manufacturer with clear ratings and certifications.

Durability, Safety and C5 Protection

Designed for demanding environments, the cabinet offers:

C4/C5 anti-corrosion options for the battery and C5 for the inverter

IP55 cabinet and IP66 inverter ingress protection

Industrial-grade air-conditioning for the cabinet and natural cooling at pack level

Integrated fire protection with aerosol suppression, explosion relief and fire-water inlet

These features make the Solis PrimePower 109kWh + C5 Combo - Expandable Master- Standard Version + C5 - Includes All Standard Model Items, C5 Environmental Protection and S6-EH3P50K-H a compelling commercial storage choice for coastal, industrial and high-pollution sites where long-term reliability is critical.
