Need help setting up solar electric system on our converted bus/motor home
I really would appreciate your detailed installation technical advice.
I'm using "cable distance" as the measurement of one positive or negative cable.
The bus/motor home is presently being supported by a 120 volt 20 amp electric line. We have to be careful not to overload the line.
We have purchased three 175 Watt Monocrystalline solar panels, one 60 amp MPPT controller, and a 3000watt pure sine wave inverter
We also have a transfer switch to disconnect the 120 volt line power from the system when transferring to the solar/battery energy.
1. We have (5) 12 volt batteries mounted in the bus/motor home: (2) 135 AH deep cycle lead acid, (3) group 31 100 AH lead acid
2. The cable distance from the (3) group 31 batteries to the controller location is presently 20', with 20' of 1awg gauge copper cable. ( This once was used to start a air conditioning compressor motor )
All batteries are using bus frame for negative "ground" and 1awg copper cable for positive charge.
All batteries are connected in parallel
3. The cable distance from the (2) 135AH deep cycle batteries to the controller will be 3'.
4. The cable distance from the inverter to the controller will be 3'
5. The cable distance from (3) 175watt ( wired in series) solar panels to the converter will be 100'
The controller, inverter, and connect-disconnect switch will all be mounted in a separate well vented compartment under the present location of the 12volt fuse panel and 120 volt circuit breaker panel.
The bus is located in a shady spot and the panels will be mounted 10' above the ground in a sunny spot..
I have been researching a lot and am frustrated and somewhat confused.
