Old home solar system fails completely: replace the relay or upgrade?

📍 Reddit SolarEnergy October 8, 2026 at 08:07 AM

Unconfirmed: a Reddit user in South Australia describes that the home solar system in their house, an older installation, began to fail. A manual reset (cutting the power and turning it back on) temporarily restored it, but afterward it stopped working completely. The post, classified as community discussion and not as news, asks other users two things: how much it costs to replace the relay in that region, and whether this type of failure is usually resolved by changing a part such as the relay or whether a full system upgrade is advisable.…

Manual reset gave a temporary fix; afterward the system stopped working completely.
Query from South Australia: cost of replacing the relay versus upgrading the system.

🔎 Why it matters: No official confirmation: this is a query from a Reddit user, not a verified fact. It is claimed that the solar system stopped working after a temporary reset, and the central question is whether a relay failure is fixed by replacing it or requires upgrading the whole system.

📈 Upside: Not applicable.

📉 Risk: The reset that only worked temporarily suggests an intermittent fault that the post does not yet have a diagnosis for.
