Great product for maximising solar savings
Great product for making the most of solar power by using surplus generation to heat your hotwater.

Needs re-engineering.
The unit is prone to overheating; the cable end terminals are too close together to be of different polarity, and too small for 13A stranded conductors and the fan is noisy. I have had a microprocessor misbehaving, and no constructive support from the maker. Read full review

Free hot water everyday
If you have solar panels & an immersion heater, we have 1 in our unvented water tank, this nifty little box will constantly top up your hot water. It works by sensing when you are exporting excess electricity back to the grid, it then transfers that excess into your water tank/immersion heater and you will have a constant supply of free hot water. Even in the dark dingy days of winter you will get some hot water. Obviously the more light/sun the quicker and hotter it warms up. A fantastic bit of kit 👍Read full review

Battery
A good controller would have liked cable clamps easy to install and set up. Using the water tank as a battery to store the electrical energy.

A Solar PV Essential
Uses excess electricity to heat the hot water cylinder. We now have hot water without having to run the gas fired boiler.
Simple to install.
