Switchboard Upgrade for Solar Perth Homes

Solar does not always force a new board, but on Perth homes still running their original board it often does. The inverter (the unit that turns panel power into household power) needs its own protected circuit. The electrician can check whether your board has the space and protection for the inverter you plan to fit.

An older board usually falls short on one of those points. A new board or a partial upgrade fixes it. Which one depends on what is already there, and a licensed electrician can tell you after one look.

Air conditioning and a car charger follow the same logic. A board that is already full has no position left to give them.

A few things on the board point to trouble before any new gear arrives. Ceramic fuses or rewirable fuse wire instead of circuit breakers is the clearest one. Missing or unclear main-switch and supply-isolation arrangements also need assessment.

No spare breaker positions, or extra circuits squeezed in beside others, means the board is already near its limit. So does a panel behind the fuses that looks old, brittle or scorched. Adding solar panels or a heavy appliance on top is where tripping and overheating start.

A board can also look fine and still be underprotected. An older board with no RCD (safety switch) is worth fixing whether or not you add anything.

Solar adds a second source of power to the board, so the layout matters more than it does for a plain appliance. The inverter circuit needs its own breaker. The electrician identifies and isolates every source of supply before working on the board.

When the board offers no clean place to connect, a solar job often stalls and an upgrade gets added to the bill. Sorting the board first keeps the installer on schedule.

If you smell burning, see scorch marks or hear buzzing from the board, turn off what you can and call 000 if there is any sign of fire.

The electrician isolates the circuits, swaps the board, tests each one and restores the supply. Plan for the power to be off for a good part of the day. The electrician can give a firmer window once they have seen your board.

If the meter side needs work, Western Power handles disconnecting the supply first. The electrician can tell you whether your job needs that, so you can plan the day around it.

Older panels can contain asbestos. A qualified electrician stops, keeps the panel intact and has it dealt with properly before carrying on.

The price follows the size of the job rather than the label on it. A few extra breakers and safety switches cost far less than a new board with rewiring behind it.

The main drivers are how many circuits the board carries, whether the old wiring is sound, how much new load is going on and whether the meter side needs attention. A board that was never designed for more than lights and a few power points sits at the larger end.

Solar quotes do not always include this work, so a board that needs replacing can appear as a separate cost. Getting the board looked at before you sign keeps the numbers clear. You should see a clear price before any work begins.

WA homes that are sold or newly leased need at least two RCDs protecting power and lighting circuits. A board upgrade is the natural time to add them.

After installation work, the contractor must give you an electrical safety certificate within 28 days. If it never arrives, ask the contractor first, then contact Building and Energy, the WA electrical regulator.

Keep the certificate. A solar installer, a buyer or a tenant may ask to see it.
