Technical FAQs 4

What breaker do I need for a transformer isolating inverter?

For transformer isolating inverters you will need a DC breaker or isolator that is double pole (breaks negative and positive simultaneously) and is rated to break 1.25 x the Short Circuit Current (Isc) rating of the solar PV array AND 1.2 x the Open Circuit voltage (Voc) of the array. For transformerless, see ‘4’ below.
