Solar - anyone regret getting PWM charge controller?
Looking to do a solar installation and have been studying up. Think I'm pretty good on most of it, however, still struggling with the charge controller. As I understand it, the PWM kind of "chops off" power above the battery charging voltage, where MPPT is covering almost all the power down to the charging voltage, thus giving as close to all the power available.
MPPT sounds great, but comes at a cost, more than double. Enough to buy almost 200 watts of panels. I read about plenty of people that share that they are fully charged by noon or 1pm, with their MPPT controller. That means that the system has quite a bit more power than is required.
To me, it seems like a WPM could still charge the batteries, but may not do it till a little later in the day.
Is my thinking flawed?
Or am I just trying to be too cheap?
