Guardian 12v Charge Controller by Goal Zero

If you have any of the Goal Zero Solar Panels you will need this controller to charge any 12 Volt batteries that are NOT built by Goal Zero (per the "NONE-Goal Zero Batteries" in the subject title). The 12 Volt Battery list includes: Home/Business Security backup batteries; Basement Watchdog (sump pump) batteries; AGM Batteries; Flooded batteries, etc.

Note that the maximum input wattage (from the banked Solar Panels) to this charger is really 90 Watts and not the 150 watts that is misprinted on some Goal Zero brochures. This means that, for example, the controller can handle three (3) Goal Zero 22003 Escape 30M Solar Panel Briefcase at one time. My review on the Panel Briefcase (and other Goal Zero products) is found elsewhere on these Amazon pages. (As a side note, Before knowing about the printing error, I have successfully charged batteries using four Briefcase Solar Panels without any problems, but do not recommend doing so for an extended period of time.)

This unit is compact enough and self-contained to include in your Go Bag, too. I recently purchased a second unit. REDUNDANCY is important in critical asset management--except for when it comes to a wife.

Since goal zero batteries have built in charge controllers I use the guardian when I park my camper in the shade, and put my boulder 30 panels in the sun with the 30 foot extension cable and the guardian connected directly to camper batteries

This completely new design works great (from late 2013-early 2013), does what I was looking for, in a nice compact, light unit that is reasonable in cost. They even have two input ports so both sizes of connectors from their solar panels work without having to have another adapter. The unit input and output wire connections are very tight and would seem to protect against moisture at the fittings. I use two of the Goal Zero briefcase solar 30w panels to keep my rugged outdoor support TrueNorth trailer's two 12v batts topped up, while camping in remote areas off the grid and away from regular campgrounds. The 4 stars is only due to the fact that I have not tested it over a long camping trip yet. If all works out, I will come back and upgrade to 5 stars.

This is so disappointing because I have given goal zero such praise. Using their products in north and south America for work. This product is deceptive and will not work with my goal zero solar panel or my brunton. They speak of adapters but their ate none. Other than the fact that it's useless to me I like the idea of it and design. Just sucks that I can't use it.
