HOT WATER ELECTRICAL & SOLAR ENERGY CONTROL
New 20A Hot Water Circuit with RCBO, Isolator & CATCH Control
This Installed Today electrical package provides a new dedicated 20 amp circuit for a suitable electric hot water system together with switchboard protection, local isolation and a CATCH Control device for intelligent load management.
The package includes up to 15 metres of electrical cabling from the switchboard to the hot water system, a new 20A RCBO, a weatherproof isolator at the hot water unit and CATCH Control — the product previously known as the CATCH Solar Relay.
CATCH Control can manage a dedicated hot water circuit according to conditions such as available solar export, schedules and other supported energy-management settings. This can help shift hot water heating into more useful periods rather than relying only on a fixed timer.
The final circuit design, switching arrangement and suitability for the connected hot water system are confirmed by the licensed electrician at installation.
Package at a glance: up to 15 metres of cabling, a new dedicated 20A hot water circuit, 20A RCBO, weatherproof isolator and CATCH Control smart load-management device. Additional cable beyond the included 15 metres is charged at $20 per metre installed.

CATCH POWER
What Is CATCH Control?
CATCH Control is CATCH Power's current name for the device previously sold as the CATCH Solar Relay.
CATCH Power describes it as a universal energy meter and multifunctional solar load-control device. It can monitor site energy behaviour and control a dedicated electrical load according to configured conditions.
For an electric hot water application, CATCH Control can be configured to switch the hot water circuit according to criteria such as:
- Available surplus solar
- Time-of-day schedules
- Minimum run-time requirements
- Supported energy-price signals
- Remote load-control settings
- Compatible inverter or battery integrations
HOW IT WORKS
How Does CATCH Control Manage Hot Water?
CATCH Control measures energy conditions at the property and can switch a connected hot water load according to the settings established during commissioning.
For example, the system can be configured to operate the hot water circuit when sufficient solar export is available. It can also use scheduling and a top-up period to help ensure the load receives a required minimum operating time.
The exact control strategy depends on the solar system, connected appliance, electricity tariff, inverter or battery arrangement and commissioning settings selected for the property.
CATCH Control is a switching controller, not a proportional solar diverter. When a controlled load is switched on, it operates according to its normal electrical demand. It does not continuously vary the power delivered to the hot water element in the way Green CATCH does.
CATCH CONTROL VS GREEN CATCH
What Is the Difference Between CATCH Control and Green CATCH?
CATCH Control
CATCH Control switches compatible dedicated loads on and off according to solar availability, schedules and supported energy-management rules. CATCH Power lists hot water, heat-pump hot water, air conditioning, pool pumps, irrigation, underfloor heating, lighting, fans and other dedicated circuits among potential applications.
Green CATCH
Green CATCH is a dedicated solar hot-water diverter for suitable resistive loads. Instead of simply switching the full load on or off, it can progressively divert available surplus solar into a standard resistive electric hot water element.
The correct CATCH Power device depends on the hot water type, solar size, tariff, battery arrangement and the control outcome required.
SOLAR SELF-CONSUMPTION
Why Use Solar to Control Electric Hot Water?
A standard electric storage hot water system can represent a significant controllable household load. Where a home already has rooftop solar, shifting suitable heating periods into solar-production hours can increase the amount of generated energy used within the property.
CATCH Control is designed to help coordinate loads with available solar and other operating conditions rather than relying solely on a simple fixed timer.
The actual financial benefit depends on the solar system, hot water demand, electricity tariff, feed-in tariff, household consumption, weather and control settings. Savings are therefore property-specific and should not be represented as a guaranteed annual dollar amount.
REAL-TIME MONITORING
Can CATCH Control Monitor Household Energy Use?
Yes. CATCH Power provides live energy monitoring and remote load-control features through its current monitoring platform.
CATCH Control can provide visibility into site consumption and generation data, helping homeowners understand when energy is being imported, exported and consumed by controlled loads.
For compatible installations, CATCH Control can also perform functions normally associated with an inverter consumption meter while adding smart load-control capability.
WI-FI & CONNECTIVITY
Does CATCH Control Need Wi-Fi?
CATCH Control includes Wi-Fi and Bluetooth connectivity.
Wi-Fi is required for online monitoring and is also important for applications involving dynamic or flexible export requirements, remote functions and supported wholesale-market integrations.
CATCH Power states that ordinary local load control can continue from local CT measurements if Wi-Fi temporarily drops out, depending on the commissioned configuration.
Bluetooth is also used during configuration and provides a local method of communicating with the device.
SOLAR & INVERTER INTEGRATION
Does CATCH Control Work With Any Solar System?
CATCH Control can perform dedicated load control without requiring direct integration with every inverter.
For more advanced functions — including inverter control, battery orchestration, export management and deeper system data — compatibility depends on the specific inverter, battery and equipment installed at the property.
CATCH Power maintains a current integration and compatibility list covering supported equipment. Compatibility should be checked before relying on an advanced integration feature.
HOT WATER SUITABILITY
Which Hot Water Systems Can Use This Package?
This particular Installed Today package is based on a new dedicated 20A circuit. The connected appliance must therefore be suitable for the electrical design confirmed by the electrician.
Electric Storage Hot Water
Suitable resistive electric storage systems are a common application for solar-aware load control.
Heat Pump Hot Water
CATCH Control can be used with compatible heat-pump systems, but the control method may differ from a conventional resistive element and can involve signal or demand-response control rather than simply switching the appliance supply.
Other Electrical Loads
CATCH Control can support many dedicated circuits, but this Installed Today package is specifically scoped around a suitable hot water circuit.
A 20A circuit is not automatically suitable for every hot water system. Appliance rating, manufacturer requirements, existing wiring, circuit arrangement and control method must be checked before installation.

15 METRES INCLUDED
What If the Hot Water System Is More Than 15 Metres From the Switchboard?
The standard package includes up to 15 metres of cabling between the switchboard and hot water system.
If the required installed cable run exceeds 15 metres, additional cable is charged at $20 per metre installed.
The final cable route is determined on site. Actual cable length can differ from the straight-line distance because the electrician may need to route wiring through ceilings, wall spaces, external paths or other accessible areas.
ELECTRICAL SCHEDULING
When Is the Additional Electrical Work Completed?
Where this electrical package is purchased in addition to a standard like-for-like hot water installation, the additional electrical component is scheduled separately.
Within 48 Hours
Installed Today's supplied service terms state that the electrician will provide a confirmed electrical installation time within 48 hours of order processing.
Within 5 Business Days
The additional electrical work is scheduled to be completed within 5 business days of the order being processed.
Separate From Hot Water Installation
These electrical scheduling timeframes apply to the additional electrical work and are separate from the standard hot water system installation appointment.
Where the standard hot water installation can be completed independently of the additional electrical upgrade, the hot water installation can proceed while the extra electrical component remains separately scheduled.
CATCH CONTROL FEATURES
What Else Can CATCH Control Do?
CATCH Control is broader than a simple hot water timer. CATCH Power's current platform can support several energy-management functions depending on the installation and compatible equipment.
Solar-Aware Load Control
Loads can be controlled according to solar export conditions rather than only a fixed clock schedule.
Advanced Scheduling
Different operating schedules and minimum-run requirements can be configured to suit the connected load and household energy plan.
Remote Load Control
Connected and commissioned systems can support remote control of compatible loads through CATCH Power's monitoring environment.
Energy Metering
For supported inverter systems, CATCH Control can perform energy-metering functions and provide consumption and export information.
Battery & EV Integration
Compatible systems can support additional battery and EV charging functionality beyond basic hot water control.
Dynamic Export Support
CATCH Power lists CATCH Control as supporting dynamic and flexible export applications in relevant Australian jurisdictions when correctly configured.
2-CHANNEL OR 6-CHANNEL
When Might a Different CATCH Control Configuration Be Required?
CATCH Power currently offers different CATCH Control configurations for different levels of site complexity.
The standard device can be used for applications such as energy metering and control of a dedicated load. CATCH Power's 6-Channel CATCH Control is intended for more complex single-phase, split-phase and three-phase sites requiring additional measurement, control or DRM functionality.
A multi-load, complex battery, three-phase, EV or advanced demand-response installation may therefore require additional equipment or a different CATCH Control configuration outside the scope of this standard 20A hot water circuit package.
SMART HOT WATER CONTROL
Why Add CATCH Control to a New Hot Water Circuit?
A new dedicated circuit creates the electrical pathway required by the hot water appliance. Adding CATCH Control introduces an additional layer of energy management.
Instead of treating the hot water system as an uncontrolled load, the system can be commissioned to operate according to solar conditions, schedules and other supported control rules.
For a solar household, this can help increase self-consumption by moving more controllable energy demand into periods when suitable solar generation is available.
