If you deal with your solar panel circuit breaker tripping all the time, you want to know the reason behind it. At PES Solar, our technicians deal with all sorts of solar panel issues. So we created a list of five common reasons your circuit breaker might trip.
Why Your Solar Panel Circuit Breaker Trips
Each solar panel circuit breaker has a current limit. Once a circuit current higher than that limit surges through the system, the circuit breaker trips. Overloading occurs when you have too many appliances plugged into an outlet at once.
The circuit’s break prevents damage to the amp fuse, which can melt when a high current flows through it. You can mitigate this issue by unplugging any unnecessary appliances from shared outlets. You may also need to change the fuse size.
#2 Malfunctioning Combiner Box
Sometimes, the combiner box malfunctions while delivering solar power from the panels. Combiner boxes merge the power of your solar panels through solar strings. Your combiner box might not work for a couple of reasons.
First, you may have a low-quality product. This issue requires professional replacement and installation. Another common problem involves a lack of maintenance.
Since combiner boxes remain exposed to moisture, dust, and fluctuating temperatures, like most electrical appliances, it degrades over time. Regular maintenance and inspection prolong a combiner box’s function and longevity.
#3 Panel Issues
Most solar panel manufacturers provide high-quality panels that last for years. However, errors can occur. For example, a panel might endure more damage during shipment than it usually would, causing panel issues.
Additionally, solar panels are exposed to outdoor elements year-round. As a result, debris, temperature changes, and extreme weather contribute to the equipment’s degradation.
#4 Wiring Problems
Sometimes, the electrical circuit breaks; the electricity then finds a quicker way to ground itself. The grounding occurs outside your solar system, causing your solar panel circuit breaker to trip. You may need to replace your circuit box to solve such wiring problems.
If you suspect wiring problems of any variety, seek assistance from an electrician or a solar panel specialist. Exposed, frayed, or damaged wires posit serious risks like electrocution.
#5 Problematic Inverter
If your system undertakes AC at a higher voltage than DC, it may translate into problems with your inverter. When this occurs, the uneven voltage will trip your circuit breaker.
A battery-operated system uses charge controllers rather than an inverter. The charge controller regulates battery charging functions.
