Sick of high electricity bills?
Electric hot water represents 1/3 of the average electricity bill!

With rising cost of living, saving every dollar matters. 

The average family of four uses on average
8-10 kWh's per day, to heat their hot water.

With recent electricity price increases this can cost as much as
$0.25 /kWh
 which could add up to $2.50/day!

meaning the average family of four can be paying over $700 every year to heat their hot water.

"At first we didn't understand the importance of offsetting our hot water usage, I guess we thought it would 'magically' be taken care of with the solar. It wasn't until we got our first bill after the solar was installed that we realised just how much our hot water was costing us. It worked out to be about $170 a quarter! 

I found out about Green CATCH on a solar forum and reached out, they were friendly and helpful and answered all my questions. 

Once the Green CATCH was installed we quickly saw the savings, we have the unit in "Solar Only" and haven't paid a cent for our hot water since!" - Jo

* CATCH Power has developed this helpful savings calculator to give you an idea of your potential savings when using our system. Please note that the figures provided are based on a 90% offset and are intended as estimates only.

While we have gathered information from reliable sources and past experiences to ensure accuracy, it's important to understand that your actual results may vary. There are several factors beyond our control that can affect your savings. For instance, if your hot water consumption exceeds the capacity of a single tank, there may still be a heating cycle that relies on Off-peak or mains electricity.

We aim to provide you with a useful estimation, but it's essential to consider individual circumstances and usage patterns when assessing the potential benefits of our system.*

Protect yourself from rising energy costs by using more of the solar energy your system produces! 

Introducing Green CATCH - the smart solution for maximizing your solar energy and optimizing your hot water usage.

Green CATCH is installed in your meter box and is constantly monitoring your exported energy. Our advanced algorithms detect when you have excess solar power and seamlessly redirect it to heat your everyday electric hot water tank. Don't send your surplus solar to the grid for a low feed in Tariff, offset one of your largest loads within the home.

And the best part? Green CATCH is compatible with all new and existing single phase solar systems, making it a hassle-free addition to your existing solar system.

On a typical 5 kW system Green CATCH will offset a  staggering 85-95% of your hot water usage. 

We know that not every day is a perfect solar day and some days you just might not have enough solar to fully heat your hot water. Green CATCH allows for your off- peak to be hard wired into your unit, so any boosting that may be needed can be done on the cheapest tariff. *some network exclusions apply*

No Off-Peak, No Problem!

Green CATCH is smart enough to recognise this and will schedule any boosting during your off-peak times for properties with Time of Use Meters. We've got you covered!

I have a Green CATCH and it works perfectly as described. I have a 8 kW 3 phase system installed therefore I only ever give 2.6kW's to the hot water, I have disabled my off peak supply and I'm running completely from solar, it heats my 315l tank and provides all my hot water needs 100% solar (I did balance my phases to the only thing on that phase is the hot water)


I have a 10.73kW solar system and a 10 kWh Battery and are part of a VPP. I DIDN'T REALISE THAT MY HOT WATER DREW FROM THE GRID! With all the increases in tariffs my control load is now averaging over $90-$100 a month. I had a Green CATCH installed by Ecolectrical and the control load on smart meter hasn't moved since. I love the options to change settings, for example to heat hot water on solar only which basically puts my in off grid or I can boost if family come to visit. Their aftersales service has been fantastic, polite and great helpful advice. A great investment that I highly recommend.

I recently had a Green CATCH device installed and have been delighted with the results. Now my hot water is being heated during the day by my generated solar. This has resulted in minimal usage from the grid. I whole heartedly support the installation of a CATCH Power system to gain the best value from the installation of solar panels.

Service is second to none, very knowledgeable staff. is a great device to work with your solar system. Highly recommend.

First I had solar installed 12 months ago and it reduced my electricity bill enormously and then I realised that my hot water was heating during the night and my bill was still $85 a month, I had a Green CATCH installed 3 months ago and now my electricity bill is $15 per month!! Best thing I ever spend my money on!!

Green CATCH vs. CATCH Solar Relay for Hot Water Heating

Green CATCH is our most efficient method of heating hot water. It can send small amounts of energy to the hot water system and closely match the hot water load with surplus solar power. This helps optimize energy usage and increase savings.

On the other hand, the CATCH Solar Relay operates differently. It doesn't have the capability to send small amounts of energy to the hot water system. Instead, it can only turn the hot water system on or off. Hot water is a significant energy-consuming load in a home, second only to air conditioners. Therefore, it's crucial to ensure that the solar system size is large enough to support the hot water load effectively.

It's important to note that when considering the CATCH Solar Relay as a solution, it's not just about finding a cheaper option. If the solar system size is insufficient, it may lead to dissatisfaction.
We generally recommend a minimum system size of 8 kW to adequately support the hot water load, with the CATCH Solar Relay.

Green CATCH offers greater efficiency by matching the hot water load with surplus solar power, while the CATCH Solar Relay provides on/off control but doesn't provide the same level of energy optimization for hot water heating. It's important to consider the system size when choosing the appropriate solution to ensure your satisfaction.

Green CATCH and CATCH Solar Relay are two separate products.  The Relay is not required to work with Green CATCH, and vice versa.  It could be that both products are installed in a customer’s home, but it is not necessary.
