Learn more by watching our CATCH Power CATCHSOLARRELAY-2CT | CATCH Solar Relay with 2 CTs video.
The CATCH Power CATCHSOLARRELAY-2CT is a solar relay rated 230VAC, 50Hz. It has two current transformer inputs for measuring power flow and switching loads up to 4 amperes. The relay combines load switching, timer control, and inverter management. It includes Bluetooth and Wi-Fi connectivity for monitoring and remote control.
Solar installers and electricians need flexible load control to boost self-consumption when solar export is undervalued. The CATCHSOLARRELAY-2CT manages hot water, air conditioning, and pump circuits by switching them on when surplus solar is available. This cuts reliance on grid power and improves system efficiency. Installation is simple with standard DIN mounting and 1-metre current transformer leads, fitting single and three-phase systems.
Licensed electricians value the CATCHSOLARRELAY-2CT for its compatibility across inverter brands via MODBUS and Wi-Fi. The Monocle app and remote on-off control let customers optimize load timing from their phone. This adds value to the service and improves customer satisfaction. The relay pays for itself by reducing grid exports on systems where export pricing is poor or restricted by network operators.
The CATCHSOLARRELAY-2CT is not suitable for external, wet, or damp installations. It cannot directly switch loads larger than 4 amperes; larger loads require an external contactor rated for the load, with the relay controlling the contactor's coil.
Verified Sparky Direct customer reviews: CATCH Solar Relay with 2 CTs (CATCHSOLARRELAY-2CT)
"Great product." — Steve D
"Easy to program, great app, successfully load shifts." — Hoffy
"Great device to benefit from your solar to heat your hot water." — Mick
(CATCHSOLARRELAY-2CT)
Yes, the CATCHSOLARRELAY-2CT operates on 230VAC single-phase supply but can monitor and control loads across 3-phase systems if the current transformer leads are positioned on the appropriate phase. For full 3-phase monitoring, CATCH Power offers alternative models designed specifically for 3-phase measurement and export control.
The relay is rated to switch loads up to 4 amperes, making it suitable for controlling hot water relays, pool pump contactors, air conditioning controllers, underfloor heating relays, and similar devices. Larger loads (above 4A) require an external contactor or relay rated for the full load current, with the CATCHSOLARRELAY-2CT controlling the contactor's coil.
The relay monitors power flow via the two current transformer leads and switches loads on when excess solar is being exported. This reduces grid exports at times when export prices are low or when the distribution network restricts exports, allowing customers to use more of their own solar generation instead of selling it back at poor rates.
The CATCHSOLARRELAY-2CT works with most major inverter brands (Fronius, SMA, Tesla, Victron, and others) through MODBUS, RS485, and Wi-Fi communication protocols. Some inverters have native compatibility with the Monocle app, while others may require manual configuration of communication settings.
The CATCHSOLARRELAY-2CT comes with a 5-year manufacturer warranty covering manufacturing defects and component failure. CATCH Power provides Australian-based technical support via email and phone, with documentation available on their website and through the Monocle monitoring app.
The relay uses standard DIN rail mounting (35mm width) and measures 35mm wide by 85mm high by 65mm deep. It fits into any switchboard with standard DIN rails, and the compact size makes it easy to install alongside circuit breakers, RCDs, and other protection devices without requiring panel modifications.
Installation must be carried out by a licensed electrician in accordance with the relevant Australian electrical standards (AS/NZS 3000 and AS/NZS 3017). The relay connects to the mains supply and controlled load circuits, so professional installation is required to ensure compliance and safe operation.
The CATCH Power CATCHSOLARRELAY-2CT is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
