5 Solar Charge Controller Problems (What Causes Them?)
To prevent this issue, it''s essential to pay close attention to the charging parameters and make sure they''re set correctly. Regulate Current: The controller must effectively manage the flow of current to the battery to prevent overcharging. Voltage Control: Monitoring and controlling the voltage levels is essential in avoiding overcharging …
Overcurrent
Possible causes for overcurrent include short circuits, excessive load, incorrect design, an arc fault, or a ground fault. Fuses, circuit breakers, and current limiters are commonly used overcurrent protection (OCP) mechanisms to control the risks. Circuit breakers, relays, and fuses protect circuit wiring from damage caused by overcurrent. [1]
