Boost Solar Hot Water Efficiency With the Catch Power Relay
If your home has solar power, one of the smartest ways to improve your return is to use more of that solar energy during the day instead of sending it back to the grid.
For many Brisbane, Gold Coast and South East Queensland homes, hot water is one of the biggest controllable energy loads. That makes it a strong candidate for smarter solar timing, especially if you already have an electric hot water system or are upgrading to a solar-friendly hot water setup.
The Catch Power Relay is designed to help manage when your hot water system runs, so more heating can happen when solar production or cheaper tariff periods are available. For the right home, it can be a practical add-on to improve solar self-consumption, reduce wasted export and make your hot water system work smarter.
Quick Answer
The Catch Power Relay is a smart hot water control add-on that helps shift electric hot water heating into better energy periods, such as when your solar system is producing or when off-peak electricity is available.
It is best suited to homes with solar power, electric hot water demand and a suitable installation setup. JR Gas & Water can supply and install the Catch Power Relay as part of eligible hot water or filtration installation packages, helping customers across Brisbane, the Gold Coast and nearby South East Queensland make better use of their solar energy.
What Is the Catch Power Relay?
The Catch Power Relay is a smart energy control device designed to help manage electric hot water operation more efficiently.
Instead of letting your electric hot water system heat at less ideal times, the relay can help control when the system runs. This means your hot water can be better aligned with solar generation, off-peak electricity windows or programmed energy settings where suitable.
For homeowners already investing in electric hot water systems, heat pump hot water systems or broader energy upgrades, this kind of control can be a useful way to improve how the home uses power.
Why Solar Homes Should Care About Hot Water Timing
Solar panels are most useful when your home can use the energy as it is being produced.
The problem is that many households generate the most solar power during the middle of the day, while a lot of hot water use happens in the morning and evening. If the hot water system is not controlled properly, the home may export solar during the day and then draw from the grid later to reheat the tank.
That is where smart hot water control can help.
A better-timed hot water setup can:
Use more solar power inside the home
Reduce unnecessary solar export
Help shift heating away from higher-cost periods
Make electric hot water more solar-friendly
Improve the value of an existing solar system
Support future energy upgrades
For solar homes, the aim is not just to produce energy. It is to use that energy in the right places at the right time.
How the Catch Power Relay Helps Improve Solar Self-Consumption
The Catch Power Relay helps manage hot water as a controllable load.
Hot water systems are well suited to smart control because they store heated water for later use. This means the system can often heat during the day when solar output is stronger, then provide stored hot water for normal household use later.
This can be especially useful for homes where the electric hot water system is one of the largest power users.
Better Use of Daytime Solar
If your solar system is producing more power than the home is using, smart control can help direct more of that energy into hot water heating.
This can reduce the amount of solar power sent back to the grid and increase the amount used by the household.
Smarter Hot Water Scheduling
Depending on the setup, the Catch Power Relay can help manage when the hot water system operates.
That may include timing hot water heating around:
Solar production periods
Off-peak electricity windows
Household demand
System settings
Tariff structure
Energy goals
The right setup depends on the home, solar system, electrical arrangement and hot water system.
Reduced Grid Reliance
When more hot water heating is handled during solar production or cheaper energy periods, the home may rely less on grid electricity for water heating.
Actual savings depend on the system, tariff, solar production, household usage and installation setup.
Catch Power Relay and Electric Hot Water Systems
Electric storage hot water systems can be simple, reliable and affordable, but they can use a lot of power if they are not managed well.
The Catch Power Relay can help make electric storage hot water more solar-friendly by improving when the system heats.
This can suit homes that:
Already have solar panels
Have an electric storage hot water system
Want to use more daytime solar
Are replacing an older electric unit
Want smarter control without moving to a full battery system
Have suitable electrical and installation conditions
For homeowners comparing replacement options, JR Gas & Water can help match the right electric hot water system with suitable control add-ons where appropriate.
Catch Power Relay vs a Standard Hot Water Timer
A basic timer can be useful, but it is limited.
A standard timer usually turns a hot water system on and off at set times. That can help if your energy usage is predictable, but it may not respond as intelligently to solar production, energy settings or changing household demand.
The Catch Power Relay is designed for smarter control.
| Feature | Basic Timer | Catch Power Relay |
|---|---|---|
| Fixed time scheduling | Yes | Yes, depending on setup |
| Solar-aware control | Limited | Better suited |
| Hot water load control | Basic | Smarter control |
| Remote management | Usually no | Available with supported setup |
| Solar self-consumption support | Limited | Stronger |
| Future energy flexibility | Limited | Better |
For some homes, a basic timer may be enough. For solar homes wanting better load control, the Catch Power Relay can be the more useful long-term option.
Is the Catch Power Relay the Same as a Solar Battery?
No. The Catch Power Relay is not a solar battery.
A battery stores electricity. The Catch Power Relay helps control when certain loads, such as hot water, use electricity.
However, hot water can work a little like stored energy because the system stores heated water for later use. Instead of storing solar electricity in a battery, the home can use solar power to heat water during the day and use that hot water later.
This does not replace a battery for the whole home, but it can be a practical lower-cost step for some households wanting better solar efficiency.
Who Is the Catch Power Relay Best Suited To?
The Catch Power Relay is best suited to homes where hot water timing can be improved and where the existing or new system is compatible with the control setup.
It may suit:
Homes with rooftop solar
Homes with electric storage hot water
Homes upgrading from older electric hot water
Households wanting to use more daytime solar
Customers with suitable installation packages
Homes looking for better hot water energy management
Properties with high daytime solar export
Customers not ready to install a battery
Homes comparing smart hot water upgrades
It may not be the right fit for every property. The setup needs to be assessed based on the hot water system, electrical circuit, solar setup and installation requirements.
What Are the Main Benefits?
More Solar Used at Home
The biggest benefit is improved solar self-consumption.
Instead of exporting excess solar power during the day, more energy can be directed toward heating water when conditions are suitable.
Better Hot Water Energy Control
The Catch Power Relay gives the home more control over when electric hot water heating happens.
This can be useful for customers trying to manage energy use around solar, off-peak periods or household routines.
Practical Add-On for Hot Water Upgrades
If you are already replacing or upgrading your hot water system, it can make sense to consider smart control at the same time.
JR Gas & Water can help customers compare hot water options, including heat pump hot water systems, electric hot water systems, and suitable control add-ons like the Catch Power Relay.
Useful for Solar Homes Without Batteries
Not every household wants or needs a full solar battery.
For some homes, smarter hot water control can be a more practical first step toward using more solar energy during the day.
Better Future Energy Flexibility
Energy tariffs, feed-in rates and household usage patterns can change over time.
A smarter hot water control setup can give the home more flexibility than a basic uncontrolled electric hot water circuit.
Important Installation Notes
The Catch Power Relay is not a DIY product.
It involves electrical integration and should only be installed by appropriately licensed professionals. Customers should not attempt to wire, alter, bypass or modify hot water circuits, solar equipment, switchboards or electrical controls themselves.
JR Gas & Water can help with eligible installations as part of suitable hot water or filtration installation packages. If the property has non-standard wiring, switchboard limitations, difficult access, old electrical components or unclear hot water controls, a written quote may be needed first.
Brisbane and Gold Coast Solar Hot Water Considerations
Solar conditions across Brisbane, the Gold Coast and South East Queensland can make smart hot water control especially useful, but the right setup still depends on the property.
Local factors can include:
High daytime solar production
Lower feed-in tariffs compared with older solar plans
Hot water systems located outside
Older electric storage systems
Switchboards needing assessment
Townhouses with access or body corporate constraints
Homes with solar PV but no battery
Families using most hot water morning and evening
