In the process of putting together a 200w system for my work service van. Complete newbie to Solar so I will probably ask a lot of dumb questions. But I also like to read so I will be searching the forum for answers as well.
 
Hi there.
1. Fix the panel/ panels securely with some air underneath to keep them cool. (mine are elevated 75 mm.
2. Thick wires from the panel to the solar controller inside the van.
3. Use wills advice for a good mppt controller - get a larger one as you might want to expand later (you cant have too many solar panels) I have enough so the freezer can still work on a cloudy day (3 amps needed)
4. Get a good battery -go Lifepo4 if you can afford it but see what you can get in your local area cheap.
5. If you have enough solar you might not have to connect your second battery to the starter one.
6. Have a joining wire so you can charge the starter if you need to. If you join them with a really thick wire you can use the house battery to help the starter when it is tired.

Thanks. My first solar system. I purcjased a 200w Renogy kit with the Rover 20amp controller, and their 100ah Lithium Battery, Leaving room to install a second battery later. Also purchased a 2000w Renogy pure sign inverter. I wont be using it for much to start with except for running battery chargers for my Milwaukee cordless tools when needed on job sites.
 
I got given a Milwaukee drill but the battery pack was gone - old nicads. I just soldered up new batteries inside the pack - NiMh. It goes a long time now. Nice tool! Makita seem to be the big one here in Aus.
 
If you want to start with a cheaper battery go to an automotive store and ask for "old stock" batteries and see what they will sell you. I normally start small until I get some more knowledge about all this. Then I expand later.
