Help with an existing solar or battery system

An inverter fault, lost monitoring connection and low generation can look similar from the electricity bill but have different causes. Unisol assesses service and repair enquiries across Hamilton Hill, Fremantle and Perth metro. Send the equipment and fault details first so we can confirm whether the work is within our service scope.

Start by telling us what has changed. An inverter error code, monitoring screenshot, recent bill or photo of the equipment often narrows the likely cause. Parts availability, warranty status and support for older equipment can determine whether repair is practical.

Common reasons people contact us

Service and repair questions

What details should I send with a service enquiry?

Send the system brand, approximate age, fault message and any monitoring screenshot. Those details help us confirm whether the equipment and fault are within our service scope before arranging the next step.

What problems can you assess on an existing solar system?

Enquiries commonly involve inverter faults, unexpectedly low production, monitoring issues, shutdowns, or questions about adding a battery. The cause and repair options depend on the equipment and the condition of the installation.

Should I repair or replace an older solar system?

That depends on the fault, equipment age, warranty status and how well the system now meets your needs. We explain the practical options before you decide between repair, component replacement or a new system.
