12kW 48V SRNE HESP48120SH3 Solar On & Off-Grid Hybrid Inverter (3-Phase)

The 12kW 48V SRNE Solar On & Off-Grid Hybrid Inverter – Model HESP48120SH3 (3-Phase) is a high-performance solar inverter engineered for commercial, industrial, and large institutional power systems across Kenya.

The HESP48120SH3 is designed to operate seamlessly in on-grid and off-grid solar environments, intelligently managing solar panels, battery storage, utility grid power, and generator input. This ensures reliable three-phase power availability during grid outages while maximising solar utilisation during normal operation.

With a 12kW three-phase output and a 48V battery architecture, the inverter delivers balanced power distribution, high efficiency, and stable pure sine wave output—making it ideal for machinery, motors, pumps, lifts, refrigeration systems, and other three-phase loads. Its advanced MPPT solar charge controller ensures efficient solar energy harvesting even under variable sunlight conditions.

Each HESP48120SH3 supplied through Macire is verified for performance, safety, and compatibility with Kenyan operating conditions. Macire also provides professional system design guidance, installation support, and long-term after-sales technical assistance.
