Solar controller question
I just bought a 100 watt RV solar kit from Amazon made by Renogy. It has a 30 amp controller but all that came with it as far as instructions is a quick start guide which ,in places, says to see th...

NinerBikes and BLF13, Thanks guys. I now see that I need around 400 rather than 100. I am just trying to find a cheaper solution to running my Honda eu2000i. We usually have 120 volt shore power except when we go to QZ.
Do you want really simple? Have a spare ladder you can lash these two panels together to to chase the sun, and a couple of hinges to pair them together and a scrap piece of carpet or astroturf to throw under them?

Basic simple PWM charge controller.
basic 15 amp plug and play charge controller.
Little more advanced and programmable, with adjustable voltage. It is second generation version, ie v1.2, which is programmable for voltage in bulk mode. 14.4 +- .9v plus programmable for various battery chemistries, lead acid, gel, AGM, Li Ion Fe, etc.
programmable 20A charge controller.
Add some wires and some ring terminals or battery clamps, and you are OK for a while. Need more? buy a 3rd panel, bump you up to 300 watts and 16.5 amps instead of ll.
Short run from the PWM controller to the batteries, mount them close together, 5 feet or less, 10 or 8 gauge wire, and 12 gauge from the panels to the controller should give you efficient low losses charging.
Put it together, and you can save yourself some fair dinkum.
So you aren't ready to build your own system, and want plug and play? How about 160 watts of portable solar panel. But this, and just add carpet underneath the panels before setting it down.
9 amps at 7 hours in the winter will put a dent in your battery charging. 63 amp hours.

Don't forget to first change out all your lights for LED's that draw a lot less current.
