Solar trickle charger help
A few months ago, we traded our truck camper for an 18 ft travel trailer. Our plan is to spend 60% of our summer vacation time on our un serviced country property & 40% of the remaining time on the r...

Hi Boon Dooker,
150 watts X .98 MPPT =~ 147 / 12.6 volts =~ 11.6 amps when using an Mppt controller. When panels were $5.50 per watt this made great sense.
I do harvest up to 21 amps from 256 watts of solar wired in series/parallel for 33 volts input to a Blue Sky 3024 controller. That is with a flat fixed installation.
The harvest would be lower with PWM. With panels as low as $0.24 cents per watt, adding more panels is today's solution.

I don't think you are going to get 12.5 amps from a 150 watts of solar, seeing as the average amperage for a 100 watt panel is around 6 amps. To get 12.5 amps you would need 200 watts of solar. Plus you have to take into consideration that the sun is not always shining at 100%
