What Our Customers Say




We fitted one of your PowerFlow units as a result of a visit to discuss power-saving measures with someone from Greenshop Solar. This was over a month ago, and as a result of the surplus energy that would have gone to the grid being diverted to our immersion heater, we have not had to use our gas boiler for water heating since. In addition, we have much more and much hotter water available. Fitting was quickly completed by Tim, which is all very compact and does not involved any major works and a very minimal amount of cable. We would strongly recommend this unit to others who have solar panels.



Excellent money saver

The PowerFlow ERS Mini monitors your main incoming power cable, your side of the meter. It detects any exported power from your solar panels and diverts the major part of that power to (in my case) the electric immersion heater in my hot water tank. So far, I have had access to hot water for over a month and have only used mains power on two occasions, thus saving on the cost of water heating. My daily consumption has fallen from 8kWh to under 3kWh per day.



I've not used the gas boiler for water heating since

E.R.S has fit seamlessly into my setup and is running with my battery storage. I now have lots of energy control that I was previously lacking. A brilliant product.

Peace of Mind Guaranteed

If you're not happy with any non-customized products, you can return them in the original packaging and new condition within 2 months hassle free.
