There is a good chance that you may see there is voltage but no amp (which means current). Why? Solar panels having voltage and no amps are mostly caused by an open circuit. In simple terms, it means your circuit is incomplete or flawed. Causes include using wrong voltage, wrong Connection, problems with panels or solar charge controller.
This occurs when the incoming voltage from the solar panels drops below a certain threshold, indicating a potential issue. Low voltage can be caused by shading, poor panel orientation, or a faulty connection. In such cases, the inverter emits a beeping sound as a warning sign. 2. Self-Test Failure:
If your solar panel, inverter and charge controller are not faulty, the most likely reason for no voltage output is poor connections. Use a multimeter to check the connection points at various areas of the solar system. You should get a reading if the connection is stable. Also look for signs of frayed or loose wires. There might also be a blown fuse somewhere.
This is the most suspected cause of this issue. When the circuit is incomplete, or in other words, configured improperly; the current can’t flow as it should, causing zero amps even while having voltage. The open circuit typically occurs due to higher load voltage, solar panel shading, reversed terminal connection, etc.
Start by setting the clamp meter to measure DC amps. To do that, turn the clamp meter’s dial to the correct amps setting. Then measure the Solar Panel’s current. Finally, compare the current reading to the panel’s max power current. That’s all about the matter when your solar panel has voltage but shows zero amps.
Two common reasons for a solar panel to register no voltage are a faulty inverter or charge controller. Other possible causes include a damaged PV module, poor wiring, shading, and temperatures higher than the ideal operating range.
