When installing a solar system in a campervan, it’s important to size the breaker for the solar shutoff correctly. The breaker is a safety device that protects the electrical system from overcurrent, and it needs to be sized appropriately for the amount of current that the solar panels can produce.
To size the breaker, you need to know the maximum amperage that the solar panels can produce. This information can be found on the solar panel’s datasheet. Once you know the maximum amperage, you can use the following formula to calculate the minimum breaker size:
