Some of the most common issues we see include:
Inverter fault codes or unexpected shutdowns
Reduced solar generation or zero output
Battery systems not charging or discharging correctly
Communication errors between system components
Damage caused by weather, age, or incorrect installation
Renewable systems combine high-voltage DC, AC power, and sensitive electronics. Guesswork can make problems worse. Proper fault finding allows the issue to be diagnosed safely, quickly, and accurately — whether that leads to repair, replacement, or reconfiguration.
We assess each system individually, checking:
Inverter performance and error logs
Battery health and compatibility
Cabling, isolators, and system protection
Overall system configuration
This allows us to identify whether a fault is minor, repairable, or part of a larger system issue.
If your renewable system isn’t performing as it should, getting it checked early can save time and money.

Solar inverters are essential to any solar power system, but like all electronics they can develop faults over time. This guide explains how to diagnose common solar inverter problems, from error codes and grid issues to overheating and connection faults.
We’re pleased to announce the launch of the new South West Renewables website.
As renewable systems evolve, more homeowners and businesses are upgrading to battery storage. However, inverter and battery compatibility is one of the most overlooked aspects of system performance.
