Solar PV String Combiner Box # Solar Panel Installation Guide # Solar PV system protection

Why we need a Solar PV String Combiner Box, what are the components available inside the Solar PV String Combiner Box

[@rizgarla3187]

Thanks for the vedio. If you have an inverter with two MPPTS the input current from the panels is 27 AMPS each . And if you combine all the strings together in the combiner box that would be more than 27 amp amps. Is that safe?

In general, 27 amps is safe. However, you must check the wires are capable of carrying 27 amps.
