Just another question on Solar

[huron52]

I have read a lot of threads on solar installs and I have a question or two.

I am thinking of adding solar to my toy hauler. Planning on about 500watts. Also planning on two 6 volt batteries to start then adding another two 6 volt batteries to the mix.

I am not interested in running my air conditioner but might want to have 120 volts to maybe watch TV or something like that.

So, correct me if my thought process is wrong here.

I plan to install solar on the roof, line down to switch then to controller and then to battery bank.
Controller not installed in with the batteries.
Then connected to the batteries, separate line off to a inverter away from batteries to get 120 volts in the cabin area.

I have dry camped for long weekends with just the batteries so 120 volts is not a biggy at this time

To save some money: use your house batteries.

Modern TV's use about 250watts leaving 250watts to charge batteries.

I work with solar. 🙂

Just remember once the sun goes down limit TV use.

Edit: I have a 60watt system that runs my laptop all day. Hence a 250watt system will run a TV all day.

Sounds good. Just don't let the existing batteries get too old before adding more. About 1 year max.
