So far I have the PV array installed, the combiner box installed, and the CC mounted. I have already wired and tested the PV array circuits to in the combiner box and they are attached to DC circuit breakers. So far so good.
From the positive bus bar in the combiner I will loop into a Ground Fault circuit breaker inside the combiner box and then out to the CC array positive in. From the negative combiner bus bar it will connect to the CC array negative in.
The CC also has a positive and negative connection for the battery bank which seems straight forward if all I was going to do is connect a battery.
Between the Battery and the CC, however, I will be connecting a 48v inverter, and possibly tying in a Anderson Power Pole fused distribution strip in case I want to make direct 48v DC connections to the battery bank.
I know I need to fuse the positive lead off the battery bank and want to be able to disconnect the CC from anything on the load side so I can isolate it when needed. The array side of the CC, as mentioned above, already has breakers to isolate it on that side.
What is the best practice to connect these components on the battery side of the CC? Positive and negative bus bars? fused bus bar? Another circuit breaker box using that bus bar to make the connections? Or something totally different? Should I put a fuse/breaker next to the battery and also next to the CC with the inverter some how tied in the middle?
Any suggestions are welcome.
