Hello, I would like to add the following DC circuit breakers to my solar system. I have researched and worked out what I think is safe , but I would appreciate any opinions :
12 v System
440ah Lead Acid Batteries
*I understand Fuses and Breakers are there to protect the cable
Inverter Breaker (Battery to Inverter) (40amp Breaker)
10mm2 Cable
375 Victron Phoenix Inverter (12v)
(375/12 X 1.25 = 39 amps)
Solar Panel to Charge Controller (20amp Breaker)
4mm2 Solar Flex (55amps)
2 x 250w Panels in Parallel. Voc = 37.3v . Isc = 9amps
2 x 9amps - 18 amps x 1.25 = 22.5amps
Charge Controller to Battery (40amp Breaker)
Tracer 40amp Charge Controller
6mm2 Solar Flex (79amps)
Thank you for your input
