Pre-Installation Checks

Important Notice

Due to changing circumstances, from 1 July 2026, we will no longer support the commissioning of new sites with the Wattwatcher Classic solution. Where WIFi is available, the CATCH Control is our recommended solution.
Existing sites with Solar Analytics and Wattwatcher branded devices will continue to operate and receive support as usual. Existing sites can continue with their subscriptions and renewals, and all sites will continue to receive Solar Analytics dashboard and support, and warranty for Solar Analytics branded hardware.

Please review the following pre-installation checks before you install the Solar Analytics Smart Monitor

Check the contents of the Solar Smart Monitor box for completeness and any externally visible damage. Contact Solar Analytics if any product received is incomplete or damaged.

Current Transformer Considerations

The Solar Analytics Smart Monitor uses current transformers to report measurement data of PV energy production and energy consumption of the home or business. When CTs are clipped around a live wire, the current going through the live wire induces a current in the CTs primary windings – which in turn induces a current in the CTs secondary windings. The current in the secondary winding is directly proportional to the current in the original live circuit and this is used for making the accurate measurements.

CTs intended to measure solar PV production can do so through a connection at the solar main supply switch.
CTs intended to measure the energy consumption of the home/business can do so through a connection at the AC main supply switch.
Any spare CTs on the Solar Smart Monitor can be used to measure sub-circuit information through a connection at the respecting load circuit breaker. Typical choices for other sub-circuits are pool, heating, air-conditioner, battery etc.

NOTE: If you are installing a multiphase application, the CTs measuring the multiphase loads need to correspond to the voltage reference frames powering the device.

The standard Solar Analytics Smart Monitor comes with 60A current transformers with 10mm internal diameter clearance. Additional sizes are available as well. Below is a list of the CT sizes available. For additional information on the current transformer sizes, refer to the Current Transformer (CT) Selection Guide.

NOTE: Rogowski coils (3000A) options only come in specifically calibrated 3CT devices and are on special requests. As there is a waiting period for these specially requested devices, please allow sufficient time to order these devices.
