Solis EverCore System 120kWh Standard Version, Includes S6-EH3P60k-H(21A)-NV

Solis EverCore System 120kWh Standard Version, Includes S6-EH3P60k-H(21A)-NV is a commercial energy storage solution designed for installers who want a clear specification, predictable site planning and a strong customer value proposition for European C&I projects. The system combines a 120.6 kWh rated energy capacity with 108.5 kWh usable capacity, paired with the included S6-EH3P60K-H hybrid inverter delivering 60 kW rated output power and 60 kVA maximum apparent power on-grid.

For your customers, the EverCore platform supports cost reduction and resilience: it provides fast backup switching with a back-up switch time of under 10 ms, helping maintain supply during grid disturbances. It also supports scalable deployment, with system expansion noted up to 1.25 MW and 15.66 MWh for larger sites, and off-grid parallel capability up to 10 units (with a recommendation for a Solis power distribution cabinet when more than six inverters are paralleled).

For installers, the physical and environmental specification makes planning straightforward. The cabinet dimensions are 1750 × 2250 × 1450 mm, or 1350 × 2250 × 1450 mm without the inverter, with a listed weight of 1940 kg for the cabinet plus 73 kg for the inverter. It operates from -25 to +55°C, up to 95 percent non-condensing humidity and up to 4000 m altitude, supporting a wide range of project locations. Ingress protection is IP55 for the cabinet and IP66 for the inverter.

Battery performance is built around LFP cells (3.2 V / 314 Ah), configured as 1P120S with a rated voltage of 384 V and an operating voltage range of 336 to 432 V. The system uses six battery packs, each 20.1 kWh and 140 kg, with a stated cell cycle life of 8000 cycles to 70 percent state of health under the stated test conditions. Maximum cycle rate is 0.5 P and maximum cycle efficiency is listed at 89 percent.

PV integration is designed for high-yield commercial arrays. The inverter supports 250 kW recommended maximum PV array size and 250 kW max usable PV input power, with 10 MPPT and up to 20 strings. DC limits include 1000 V maximum input voltage, 150 to 950 V MPPT voltage range, maximum input current of 4 × 42 A and maximum short-circuit current of 4 × 60 A.

Safety and protection features are specified for compliance-led projects: lightning protection Type II (AC port) and Type II (PV and battery), plus protections including anti-islanding, residual current detection, insulation resistance detection, AC overcurrent protection and AC cable connection protection. Fire suppression is listed as default aerosol with explosion relief valve and fire water inlet, with optional gas detection, alarms and ventilation equipment. Remote monitoring and OTA upgrades are supported via SolisCloud, helping you reduce call-backs and offer ongoing optimisation as a service.
