How to find and repair ground faults in solar PV systems
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.

hybrid high/low resistance grounded system. In this case, the generator has (2) parallel grounding paths, one at 5A and one at 100A. For ground faults external to generator, then the ground fault current is 100+5=105A. For generator internal ground faults, the 100A resistor path is tripped off-line with the generator main circuit breaker.

When to use chassis and when to wire to battery neutral?
If you can find an easy spot to mount on the chassis, this is the best place to run the ground to for three reasons. First, it''s usually a lot more convenient than running your ground to the battery. Second, it''s a really good grounding place (as in solid and works well). Thirdly, you run a lot less wire, which helps in cost and clutter.
