Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues. Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off.
Solar panel fault-finding guide including examples and how to inspect and troubleshoot poorly performing solar systems. Common issues include solar cells shaded by dirt, leaves or mould. Check all isolators are all on, and the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues.
Use a current clamp, like the Fluke 393 FC Solar Clamp Meter, to verify zero current in each PV circuit string before opening the fuse holders. Verify that no current is present, then open the touch-safe fuse holders to isolate each PV circuit string. Warning: Never measure current in a PV installation with the probe tips of a multimeter.
The System Power Components are equipped with a ground (GND) leakage current monitor. In general terms, we can understand Photovoltaic Riso faults as short circuit faults, that lead to electrical current flow in the grounding gear connecting the DC power generation and the System Power Components, see Figure 1.
While there are many advanced tools available, beginners can effectively monitor their systems with a few essential and user-friendly devices: Solar charge controllers are a crucial component in any off-grid or battery-based solar power system.
These costs are complex in nature and vary from system to system, but one driver is ground faults on the DC side of the PV array. Isolation resistance (Riso) faults are the most common DC faults in solar PV arrays. About 50 % of all PV Riso faults go undetected.
