We just bought this and like it except it keeps making a random beeping sound?? Every 5-8 minutes it seems (although might be longer). Annoying, and at night most annoying when you are trying to sleep.
We came close to picking one of these up from a friend selling his, but he told us about the beeping noise. Which happens to be the reason he was selling his. If you have solar plugged into his, the low voltage warning will go off and keep going off. Hard pass for us.
