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 ...

Now that you mentioned MPPT, here are the salient points:
1. Watts do matter! This is different from the Isc/PWM situation.
2. With MPPT and a 200W panel and 14.4V charge, you calculate charge Amps as 200W/14.4V = 13.8A. If the MPPT is 96% efficient the result to the battery is 13.8 * .96=13.3A.
3. MPPT simplifies panel selection because it allows you to focus on fitting panel(s). You might want to look at 24V panels on solarblvd.com. You will be amazed at the $/W difference from 12V panels. This is where MPPT shines.
