Advice on deep cycle setup?
Hello, I have a Safari van that I've converted into a camper. I replaced the starting battery with a Duracell Ultra Dual Purpose (Starting/Cycling) Battery that cost $105 (got it at batteries ...

7.3 The influence of irradiance
The output of a solar panel is approximately proportional to irradiance, but Vm remains nearly
constant as long as irradiance exceeds 200 W / m². Irradiance therefore does not materially
influence the MPPT / PWM performance ratio as long as irradiance exceeds 200 W / m² (see figure
16)
"But at low irradiance (overcast sky, wintertime) Vm drops rapidly and an MPPT controller connected
to an array with a much higher nominal voltage than the battery, will perform far better than a
PWM controller."
