Emergency plan for power failure of solar power supply system

If the rainy days of solar system exceed the design range, there will be power failure when the system stops the load output. If the system cannot be charged in time for a long time, the battery life will be reduced. In order to prevent this phenomenon, there are usually two emergency measures.

Direct solar panel

Turn off the load, connect the positive and negative output terminals of the solar panel with the positive and negative poles of the battery directly, and charge the battery through the controller when the battery voltage reaches the recovery voltage of the system. And pay attention to the weather forecast. If the weather is fine next, you can turn on the load. The connection of load can be handled according to weather and actual demand.

Direct solar energy connection mode, for emergency use, it needs to be guarded or regularly inspected to prevent the battery from overcharging and damage.

Charger emergency

If the battery cannot be charged for a long time, the gasoline generator and charger can be used to charge the battery. Because of the small volume and convenient transportation, the gasoline generator is more suitable for emergency charging. When choosing charger, try to choose automatic charger to prevent battery damage due to excessive current. Charging mode of charger: for emergency use, it needs to be guarded or inspected regularly to prevent over charging and damage of battery.
