The SolarHotty’s intelligence comes in when DC (solar) power becomes insufficient and the unit switches over to AC (grid) power ensuring you always have hot water. It’s a peak saving device for your hot water tank and effectively turns it into a solar battery where the energy generated is stored for later use as hot water.

What this means in simple terms is that DC power from solar panels can be used to directly power the element that you find in your existing hot water tank, effectively converting your 50, 100, or 200 litre hot water tank into a hybrid green heater.
