3ph manual switchovers backup package for power cuts

Package includes a manual switchover with necessary re-wiring for full house back up during outages.

Please note: This is only available to purchase together with an installed system.

A manual switchover setup for backup power involves installing a manual changeover (transfer) switch at the main power supply point of a home or business. This switch enables the user to physically disconnect the property’s electrical load from the public utility grid during a power outage and connect it to an alternative power source, such as solar-generated power with battery storage or a generator.

How Manual Switchover Works

• Normal operation: The changeover switch connects the home load to the main utility grid, supplying electricity as usual.
• During a power cut: The user manually flips the switch to the backup mode. This action physically isolates the home’s wiring from the grid connection to prevent back-feeding electricity into the utility lines (which can be dangerous).
• Once isolated, the switch connects the home electrical circuits to the backup power source, which could be an inverter fed by solar panels and batteries or a backup generator.
• The inverter detects the grid failure (no voltage on the grid side), then starts supplying the house with stored solar/battery power.
• Switching back to the main grid after power restoration requires manually flipping the changeover switch back to line power mode.
