Time to finalize some things, and I keep banging my head against the wall in an attempt to make one final parts order. This is in an RV w/ lead acid batteries. Diagram (incomplete) attached. So, a few questions I've been unable to find answers for:
- Way too many things attached to the most-positive battery terminal. Time for busbars.
- On the positive side I have a 150A ANL fuse between battery and inverter. I think the busbar should go in between the fuse and the inverter, right?
- Devices connected to the positive busbar would be include two SCC's - one is 4 100w panels in 2s2p configuration. One is 2 100w panels in serial. Would an MRBF fuse at the busbar work for these?
- Also connected to the busbar are an Iota DLS-55 charger, the power cable for the shunt bluetooth circuit, and an exhaust fan thermostat. It has two 30A fuses but I think those are for reverse polarity. Does the charger need a fuse at the busbar? If so, would an MRBF fuse work there as well?
- On the negative side:
- I think the busbar would need to be off of the shunt opposite of the end connected to the battery, right?
- Need to move the Iota charger negative and vent fan negative to busbar.
- Both SCC negatives would go to the busbar as well, correct?
- The two new solar panels are portable, but probably too big to hinge together. I will be connecting them in series w/ Anderson Powerpole connector. This will be just one red and one black wire, and I can't find any sort of weatherproof boot for just one wire. Any ideas? I'll be connecting black to red, which seems to not be something these connectors are made for.
- Each time I set them up, I'll need to take the other two wires and connect them to my PV extension cable w/ an SB50 connector. Can't figure out how to do that and keep the connection weatherproof... any ideas there?
