Goal Zero Pro 4000 battery keeps beeping

[Jared McDaniel]

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.

It means low power input.

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.

Bought this and returned it for that exact reason. Beeping is very annoying at night and will wake you if you are a light sleeper.
