RV Solar

The info about our 258 Watt Solar Set-up for our old trailer is here:


Here's what we have now on our new motorhome:

The system:

Two 160 Watt Solar Panels (320 Watts Total)
Four 6 Volt batteries
A Sunforce Charge Controller with Readout Screen
A 600 Watt Modified Sine Inverter connected to the batteries for most of our AC (plug in outlet) needs
A 300 Watt Modified Sine Inverter in the cigarette lighter in the back of the coach to run my laptop and charge cell phones.

The inverters aren't ideal, but they're what were available at the store when we first started boondocking and needed a quick off-the-shelf solution, so that's what we're sticking with for now. If the 600 modified sine ends up being too much trouble I have it set up on cables that can handle a 1000 watt inverter.  I can swap it out myself by just unscrewing the leads and screwing new ones in.  We did this on purpose just in case.

The inverters both have fans that go all the time.  I'm fine with that.  We're talking very few amps and the ambient noise helps drown out background noise.

I did not get a tilt system for the panels.  I'm not going to climb up on the roof anymore.  x_x It's just too hard for me.  They're fixed in place.  The price for everything was $2,100.

Right now with clouds and wind we're at 13.1 on the charge controller.  I'm good for as low as 12.1 according to the installers.  So far it hasn't gone below 12.3.

We got our solar done at the 'Solar' place by the Christian Service Center on Ferguson Rd., Winterhaven CA.  I highly recommend them.  If you call the places in Yuma during winter you're probably going to have a few week wait.  These guys saw us right away.


We now have a 1000 Watt Pure Sine inverter.  The little ones broke and weren't suitable for our needs.  We also added another 160 watt panel and two more 6 volt batteries.  We just couldn't get through the evening comfortably before.  We were limping by bed-time.

So now we have 480 Watts of solar panels and a battery bank of six batteries.  This is on an 80amp fuse since we blew the 30 amp fuse pretty quick.  This is giving us all the power we need now.
