SOLIC200 WIRELESS SOLAR IMMERSION CONTRL

The SOLiC 200 Wireless Solar Immersion Controller from Earthwise Products Ltd is designed to maximise self-consumption of your solar PV by diverting surplus generation to your hot water cylinder. Instead of exporting excess electricity to the grid, it automatically feeds just the spare power to your immersion heater, helping reduce energy bills and make better use of your renewable generation.

The wireless setup separates the sensor at the meter/consumer unit from the controller at the hot water cylinder, reducing cable runs and simplifying installation. The system continuously monitors household demand and PV export, then proportionally adjusts power to the immersion heater so household appliances always take priority.

With smooth, automatic operation and no changes needed to your plumbing, the SOLiC 200 Wireless provides a simple, low‑maintenance way to produce hot water from energy that would otherwise be exported. It is suitable for standard resistive immersion heaters and typical single‑phase solar PV systems.
