The Solar System Troubleshooting course you will learn to work backwards from a faulted electrical condition to discover the root cause of your electrical problem. Your primary tools are a digital multimeter and megohmmeter, plus your powers of observation. You work through a wide variety of faulted conditions, including no DC power coming from the solar array, no AC power coming from the utility side, and a ground fault indication. You also deal with a system that is fully operational but is producing too little power. By systematically looking for and eliminating typical mistakes, you eventually get to your root cause.
