Calling on Solar Techies
I have been thinking of going solar for some time and decided to pull the plug. My wants are a 400 to 500 watt system. I have four 12 volt batteries with 340ah. I am not planning on changing b...

I am planning my storage compartment which is within 5 feet of my Battery box for my solar control center. I need to make room for the Charge controller which is very small and the 2000w inverter which will be big plus various switches and fuses.
Each device will need to connect to the battery bank. Is there any problem putting in a positive and negative Buss bars for connecting the inverter and Charger Controller OR does each one have to be connected directly to the battery separately?
I plan in putting disconnect switches between the solar panels and Charge Controller and a 50 amp breaker between the charge controller and battery.
I plan on a cut off switch and 200amp fuse between the Inverter and batteries. A positive and negative Buss bar would make things easier
You can run your controller output wires over to the inverter so the inverter's input terminals are acting as busses. Your monitor's shunt on the neg side holds all the neg wires at one end and has just the one fat wire to the neg battery post. You could need a neg bus when there are too many wires "stacked" on the shunt.
The various pos wires to a pos buss bar are each fused to their own gauges. Then the fat wire from the buss has its own fuse for its fatter gauge. The fat wire out must have the ampacity of the total amps of all the input "branch" wires to the bus.
You cannot run the converter output wires to the input wires of the controller. Keep them separate until they get to the buss or battery.
