Adding Solar.
Hey guys, I just got my first RV! My RV is a 97 Winnebago adventurer. I already own 150 watt solar panel array that charges a 110AH costco deep cycle. The RVs coach batteries are two 75AH deep cycles....

Best practise is
A. two volt cells in series (not often possible in an RV)
B. all jars identical in make, age and capacity, wired in a balanced manner
Ideal charge controllers have adjustable set points, a temperature sensor at the battery bank, and battery voltage sense wires.
Folks who have done real world testing find about an 8% improvement in harvest using mppt under perfect solar conditions. The jury is still out about NON ideal conditions such as low light or partial shade.
I chose to do series/parallel with mppt, but that was when cheap panels were $5.50 per watt. I got lucky and my system works extremely well. With cheap panels, if there is sufficient unshaded room on the roof, it maybe more cost effective to use an ideal pwm controller.
Some folks here use the Tracer which appears to be a 'knock off' of Morningstar.
ebay controller unlikely to be true mppt
I figured it was probably too good to be true ;)
Thanks for all the info!
What about wind turbines?
Seems then that I could also just plug one of these on? Where I camp usually it gets pretty windy, so when its cloudy, could this take over charge duties?
Wind turbine
It appears to be using a solar charge controller also.
I assume its better to get a wind/solar hybrid charge controller, but can you just use two seperate ones to start?
