Technical FAQs 4

Do solar panels need a breaker?

Solar panels are grouped into strings, and each string needs a breaker to protect the wiring between the panels and the inverter. The inverter, which converts DC power from the panels to AC power for home use, requires breakers on both its input (DC) and output (AC) sides.

How to choose the right circuit breaker for a solar PV system?

Choosing the right circuit breaker for a solar PV system is critical. A circuit breaker protects the system from overloads and short circuits, preventing fires and damage to panels, inverters, and wiring. Using a breaker that is too small can cause it to trip constantly; one that is too large won’t trip when needed, risking danger.

What size fuse or circuit breaker for a solar panel string?

To determine the normal fuse or breaker size use this equation: String circuit ampacity = Short Circuit Current (Isc) X 1.56=Fuse Size. For the DC side of the circuit, the short circuit current (Isc) is used for this calculation.

Do I need a breaker for a 500 watt solar panel?

For 500-watt panels, a string of 4 panels has a maximum current of around 14.0 amps. 125% of 14.0 amps is 17.5 amps, so a 20-amp breaker is required. The same applies to a string of 6 panels with 500 watts each, which also has a maximum current of 14.0 amps, needing a 20-amp breaker.
