Solar, Alternator/Starting Battery and Lithium Solution

Fifty amp limit to charge batteries is not a heck of a lot. It's an attempt in the right direction but 200 amp-hours delivered in a 4-hour drive doesn't tweak my beakie. Especially if that includes solar input. A gross limit in other words. A net limit, alternator only, plus the ability of a 40 or 50 amp panel addition would be a lot better IMHO.
