Solar Charger for 24 volt batteries

[M20S Driver]

Is anyone using a solar charger for the 24 Concord batteries?    I have a battery minder but no power at the tie down at KPAO.   I saw this used on a Cessna 182 with 24 volt system

My hangar does not have power and I use Solar Battery Minder for my Bravo (24V dual battery system).

I have a 4 prong connector nest to the O2 port to connect the charger, but I do not charge both batteries at the same time (have a selector switch at the charger to pick which battery will be charged). There is a schematic published somewhere on MS for a connector that let;s one charge both batteries, but I decided to do one battery at the time to avoid any issues caused by different charge levels of the two batteries. The panel is pretty compact so you could probably use it at tiedown.

Works quite well so far.
