Solar Hotwater

Green CATCH is a device that utilises your existing solar installation to heat your hot water.

Taking control of your solar energy
CATCH will divert the solar energy that is excess to your home and use it to heat your hot water. Forget about constantly changing tariffs.

Save hundreds of $/year!
There are significant savings to be made by making better use of your solar electricity.

Intuitive programming to improve efficiency
CATCH is always assessing how much off-peak has been used and adjusting to maximise the use of your solar.

How does it work?

Green CATCH is simply a diverter of solar power that is excess to your household.


  • CATCH is installed in the meter box.
  • CATCH monitors power coming and going from your premises; when the diverter senses power leaving it redirects that power to your hot water service.
  • The CATCH Control Pad gives the owner greater control of their hot water heating allowing for shorter days in winter, or an extra boost if required.
  • The Control Pad can be adjusted to heat water immediately (from general tariff electricity), to never using the mains at all. Great if you are going on holiday!
  • Green CATCH will automatically adjust the timer set to make the best use of your solar. It learns every day.

What our Clients Say

I ended up looking into solar as an off grid solution when the price to get power to my house block was much more than expected. After doing some research and speaking to a few different solar providers I decided to go with Donnas Electrical. Hoping that by going local follow up service and quality of products would not be an issue, I had read plenty of horror stories. To be honest I could not be happier with my choice. Kane was able to supply a system to the budget I had in mind (which was quite a strict budget), on par with other quotes I had received and half that of getting the house connected to grid power. The installation was done to my time schedule and most importantly everything was very neat and tidy. Follow up service has been magnificent and I have no concerns that if I'm ever to have an issue they will be contactable. Every thing has worked exactly as it should and to the quality I expect. I would recommend dealing with the team at Donna's Electrical to anyone.

Having read information in the Advertiser and online, and having compared all the batteries available we decided that the Telsa 2 was the best battery for our 5kw solar system, A friend recommended Donna's Electrical to us after his installation, as he couldn't be happier with it. Donna's did all the paper work for the government subsidies etc and turned up and had the new battery fitted, wired to the internet and even put the app in our phones before they left. We are very happy with our system and are counting the savings using our own solar rather than having it go into the grid for chicken feed. We have already recommended Donna's to a neighbour who will have a new installation shortly.

Having solar panels installed was definately the best investment I have ever made and getting the Tesla Battery was the icing on the cake.  Finally in credit, yay one happy customer!

Thank you to Kane and the team at Donnas Electrical for the supply and installation of our solar and battery at Bordertown.  Your service and communication from start to finish was fantastic.  Loved also that the person who quoted did the installation.
