I discovered that the AC outlets are wired incorrectly when I could not use the Andes 1500 as a power backup for my furnace - even when in AC pass-through mode - due to reverse polarity of the outlets generating a furnace error code to that effect, which I confirmed with an outlet tester. The AC works for polarity-insensitive devices (eg the thermostat and blower fan function) but any sensitive electronics (eg the ignition system) may not function correctly.

This review is for the ECO-WORTHY 100 watt portable solar panel. If you have a few 100 watt portable solar panels, you know they fall into a few design categories. This panel breaks that mold. First, they are very light compared to my other 100 watt panels. They have a rubbery feel. There is an obvious wire that goes between the two panels. It looks more robust than other solutions. The kick stand are unique in my experience. They work well in firm ground. I don’t think they would do well in sand or soft ground. The legs have a dedicated slot to hold them which also helps protect the solar panel when stowed. If you don’t like that location, they will fit in the water resistant zipper bag that is attached to the back of one of the panels. I tested the panel in full sun and with clouds. With full sun, I got 79 watts (after the panels warmed up). With lots of clouds, I got 10 to 36 watts depending on how much the sun peaked through the clouds. I did not spend a lot of time fussing over the setups. I angled the panels toward the sun and called it good. Overall, I’m impressed! I hope to see more of this innovation.
