SolarEdge and Enphase Remedial Works
​
If your SolarEdge or Enphase system isn’t performing as it should, you’re not alone. Many homeowners and businesses experience issues after their original installer has ceased trading, leaving them without support. At Solar Plants Maintenance, we specialise in diagnosing, repairing, and optimising SolarEdge and Enphase PV systems across Swansea and South Wales.

Our Diagnostic & Repair Process
System Assessment – We begin with a full on-site inspection and monitoring check using manufacturer tools (SolarEdge SetApp, Enphase Toolkit).
​
Fault Identification – Our engineers locate the root cause of inverter or communication faults quickly and safely.
​
Component Replacement or Repair – We use genuine SolarEdge and Enphase parts and ensure correct firmware and grid profiles are applied.
​
Performance Optimisation – Once repairs are complete, we test and verify system performance to restore full generation.
​
Monitoring Reconnection – We’ll reconnect your system to SolarEdge Monitoring or Enphase Enlighten and provide full visibility again.
Multiple services
We offer discounts when combining multiple services, making system upgrades and repairs more cost-effective. If you require an optimiser replacement or microinverter replacement, we can also install bird protection while we are on-site. If your system already has pest prevention fitted, we can carry out a full panel clean or a solar health check during the same visit, saving you time and money.​​
