Fault Diagnosis First
We confirm the inverter is genuinely the fault, not an isolator, string, or comms issue, before you spend anything.
Maintenance · Inverter Replacements
System down? Get generating again.
Failed and end-of-life inverters replaced with correctly specified units, fully tested, commissioned and reconnected to monitoring.
The inverter is the hardest-working component in a solar system and usually the first to fail, typically after 8 to 12 years. A replacement is straightforward when it is specified properly: wrong voltage window or MPPT configuration and the array will never produce what it should again.
The process
Diagnosed, specified, replaced, proven
Correct Specification
Replacement matched to array voltage, current, string layout and MPPT configuration, not just to kW rating.
Hybrid Upgrade Option
Where it makes sense, replace with a hybrid inverter so battery storage can be added now or later.
Safe Isolation & Install
Full DC and AC isolation, correct protection, tidy terminations and compliant installation throughout.
Testing & Commissioning
String testing, performance verification and monitoring reconnected so you can see it working.
Documentation & Warranty
Certification, updated system records, manufacturer registration and DNO notification where required.
