Solar charging

[Robo]

where is the Engel if in the Patrol? I would suggest either parking in the shade and running a lead to your Panel,
or darken the cargo area with either that silver foil sheet, or black perforated stick on.
Out of interest how many AH does the 150 panel produce on a sunny day.
You may have been better with two 80 Watt panels, I'll wait
Edit its 8.5 AH ,You might get 9AH running a twin 80 panel marginal

Thanks for the input.
engel sat under vans annex in the shade, in its genuine transport cover.
it was that humid/warm condensation was forming under the cover.
did take it with us a few times, mav's cargo area is well shaded, and aircon was running.
settled on larger 150w single panel as dc/dc reg max's out at 300w.
so 2x 150w panels suit nicely if 2nd is required.
otherwise 3x100w getting bulky etc, did consider smaller but that falls short etc so I thought.
this reg can be upgraded to 80 amps charging for over 400ah and then max out 800ah.
I'm very new at solar, so hope I'm getting it right hate wasten time and $$.
my only regret so far is reg has no status gauge, bat level ah etc, but is mppt.
may have to get a monitor of sorts later down the track.
or put dc/dc reg in car for dual bats, and a different reg in van.
will see.
Boss wants larger van, and looking at weights I may have to step up to GU towing capacitys.
GQ Hayman bar 120 kg ball weight falls short on vans we have looked at so far.
I've spent a small ship load of time/money on GQ mav and now short capacity wise.
any improvements are on hold till I sort vehicles now.
always something.
