You plug in your new GaN charger, and it immediately tilts and falls out of the wall. This is a common frustration for many of us who expected a compact, lightweight device.

Why is the Step 2 Description of Leds on My Solar Charge Controller Misleading?

by Bernard Ryan

When your solar charge controller’s user manual says the LED is in “step 2,” it often means the battery is charging but not fully full.

Why is Solar Charging on My Foldable Solar Panel Ineffective when the Battery Overheats?

by Bernard Ryan

You plug in your foldable solar panel, but the battery barely charges. This happens often when the battery gets too hot during a sunny day.

Why is My Solar Panel Producing Only a Few Milliamps Open Circuit?

by Bernard Ryan

Seeing your solar panel output only a few milliamps when the circuit is open is frustrating. This reading is far below normal, and it means you are not getting the power you need from your system.
