Solar iBoost
What is the Solar iBoost
The Solar iboost is an immersion diverter, that allows you to enjoy free hot water powered by your Solar Panels. Cutting the cost of your water heating, and reducing the strain on your boiler. By installing a Solar iBoost+ you will be simply maximising your use of free solar energy generation by your solar panels. Making your home more green.
How does the Solar iBoost work?
The Sender is clamped to your electricity meter. It monitors the electricity being generated by your solar PV system and the amount of electricity you are using. This information is then sent to the Solar iBoost+.
When the Solar iBoost+ receives information that you are generating 100W more energy than you’re using, it automatically sends the surplus solar energy to power your immersion heater. The Solar iBoost+ automatically adjusts the amount of power going to your immersion heater depending on your levels of excess energy. The Solar iBoost controller is usually installed in an airing cupboard adjacent to your hot water tank.
This excess energy then heats up your water during the day according to the immersion heater’s maximum thermostat’s setting.
