Solar battery minder recommendation
I looking for a basic trickle charge solar panel so that the batteries are maintained while in storage. Could be in storage for a week or two, or several months over the winter.
I suspect that I will roof mount, flat, just above the power closet.
4x 12v , 80amp

BatteryMinder is the most frequent hit on the internet , but clearly states that mounting solar panel flat will result in water damage and failure.
I have to assume that the boon dockers have their panels up on the roof.
What should I look for?

80 amp? maybe you mean watt... if left flat in snow country they will not work as the snow will cover the panels.. they need to be tilt-able.
when I read trickle charge I came up with these

OH OK... you would be better off with 2 Trojan T105's (6 volt wired together for 112) this would give you 220 ah and much longer battery life.

Yup - but they are new, so Im sticking with the 12 volt array for now.
4 x 80 = 320 amp hour.
In the end a solar changer, I think, is more concered with amp charge rate, that if the 12 volt array is in series or parrellel.

Re-posting in hopes of any feedback from anyone using a 15 watt Solar panel with a BatteryMinder ( brand ) product.
It appears to produce about 1 amp float charge.
I think the math says that it should at least maintain the natural loss within the batteries while in storage.
Anyone?
