Reduce your electricity bill

The most affordable way to reduce your monthly electricity bill. Convert your existing geyser to Solar PV power with our new GeyserTECH+ Pi²R Micro and GeyserTECH+ Pi²R iX geyser solar units.

The geyser is one of the average household’s highest consumers of electricity and also one of the most difficult to connect to a solar system due to the high current draw. Our modules will fill that gap in your energy planning by feeding directly from solar PV panels to the existing geyser element - no need to change your geyser’s element.

The GeyserTECH+ Pi²R Micro and GeyserTECH+ Pi²R iX GSU’s are both AC and DC connected. This means one can set when grid power should be used to top up the temperature - typically early morning and late evening. This is achieved by means of a timer on the Micro and standard iX and by the programmable touch screen which comes with the iX SMART.

The use of photovoltaic (PV) solar panels means that the longevity of the system will be considerably better than that of thermal solar systems due to the lack of perishable piping.
