The immerSUN is our ‘state of the art’ energy saving device. It helps you to self-consume the green energy produced by your microgeneration system, and is compatible with all renewable generation technologies, including solar PV, wind turbine and hydro systems.
The device is essentially an automatic power controller that diverts surplus power to a designated load, normally a hot water heater, to save energy and minimise your utility bills.
Compatible with all inverters, smart meters and energy monitoring systems, the immerSUN boasts an extensive range of additional features. This controller really is the perfect addition to any PV or wind turbine installation.
Once installed, the next-generation system will reduce an average household's energy bill by up to £250 per year by diverting microgen-generated electricity directly to an immersion heater, storage heater, and/or electric underfloor heating.
This helps users to significantly reduce utility bills, lower mains reliance and improve the eco credentials of their property, without affecting FiT payments.
