Battery ... powers stuff like the water pump , lights , power winch for roof etc etc
120v will power stuff like Microwave , Television , 120v outlets + a converter (battery charger)
Fridge can be powered by electric 120v , 12v or propane
and Furnace fan is 12v the heat being produced by propane
Converter is rated in .... 12v amps OUTPUT 35, 45, 55 etc
so it can power any combination of devices upto it's maximum output
any left over output will be sent to battery so it can charge up
If battery is full ... it won't accept a charge from converter or solar
Solar will send power directly to the battery.... lets say it produces 5 amps
IF all the 12v devices are OFF the solar input is stored in the battery
BUT if you got the furnace running and charging your phone ... this might be using 6amps ... so you have a draw on the battery of 1 amp battery is getting slowly discharged
Adding MORE solar where possible will allow the battery to charge up MORE
keep in mind to turn OFF anything not required to allow the charging to go faster
7 pin connection from truck
will also provide some power .. how much power is debatable... but you will get some power from the 7pin while motor (alternator) is running
you can have MULTIPLE power sources running at the same time
Converter (shore power) + solar
7 pin + solar as you drive
they all contribute to keep battery charged
Lead acid is SLOW at charging
BUT perfectly adequate if you only camp at weekends etc
allowing enough charging to occur during the week, via
a) your current solar could take several days to top up the battery
or
b) connected to 120v to converter (use a extension cord at the house)
When your battery dies look hard at replacing it with Lithium (lifepo4)
for moderate power usage you can get a battery for around 200.00 and it will have TWICE the capacity of your old battery, It will greatly increase you camping ability.
If you like solar and want to boondock a lot
a) invest in lifepo4 battery for faster charging and more capacity
b) get as much solar on roof 2 x 200w panels
c) 200w of ground panels
a well designed solar and battery system will allow almost unlimited camping
Have camped Florida and UPTO Ohio with just solar to keep batteries happy
