Hot water is one of the best places to store excess solar energy. It’s cheaper to store it here than a battery and better than sending it back to the grid.
Fronius has come up with the Ohm pilot. This clever device can read exactly how much power you are about to send back to the grid, then instead put it into your hot water cylinder.
It doesn’t just switch on and off the cylinder, it will only put the spare power into it.
This device will really help utilise your solar production. It will reduce the amount of power you send to the grid, or draw from the grid.
Don’t ever worry about running out of hot water. This is one of the only hot water diverters that monitors the temperature of your water. If it gets lower than you have set it, then it will heat from the grid. Ensuring you don’t ever get that surprise cold shower in the morning.
On top of all this, you can also follow the temperature of your cylinder on Fronius’ monitoring platform Solar.Web.
