Xtend is designed to work with Solar PV inverters as it has a consistent and low draw of only 2kW’s. 

Using Xtend elements, we developed affordable kits that offer great alternatives to conventional solar hot water systems and heat pumps.

These systems produce electricity to heat the geyser first, and then focus any spare solar power on the day loads in the property, thus increasing the efficiency of the system.

You can use bigger inverters if you want to further target the day loads and can add panels accordingly.
