Planning Solar Panels
Hi everyone, I'm working on my very first DIY camper conversion, using a 2010 extended Ford E250. I was looking at solar panels yesterday, I was going to make the move eventually but maybe soone...

MPPT will be getting close to being on par with a PWM in the 700w area. Above 1000w go with MPPT (usually)
Again, its a cost game.
With my array 500w, I tried the following controllers, because I got in a debate with a fellow camper, who just had his friend install an array on his camper. He had the TS-MPPT-45, and I have the PWM version.
Nothing else changed:
Morningstar (PWM) TS-45 Retail price $150
Actual amperage to batteries 27a
Morningstar TS-MPPT-45 Retail Price $450
Actual amperage to batteries 23a
So... for $300 more, I could lose 4a. That's an amazing deal just because people think MPPT is better all around.
For arguments sake. Lets say the MPPT did give 4a more than my set up. I could still spend the $300 I saved on two additional panels, and be back on top.
The charge controller is very important. I went with the MS TS 45 because all its voltages are programmable. Most golf cart type batteries perform much better if you can adjust the voltages to what the mfr suggests. The TS-45 allows this, as well as voltage AND temp sensing at the battery to ensure proper charge.
