Question:
We do a lot of summer camping in Missouri where the voltage really s in the evenings. Would both the HU84ZR and HU74ZR kick in automatically when that happens, or do you have to flip a switch?
asked by: Derk
Expert Reply:
Derk, both the # HU84ZR 30A and # HU74ZR 50A handle it automatically. If park voltage sags below about 113V, the Power Center adds about a 10% boost. You don’t have to do anything - it senses the drop and corrects it so your A/C compressors and appliances stay safe. If the power gets dangerously low below ~104V, the unit will shut down altogether until voltage comes back into range.
If you have any other thoughts or concerns, let me know! Have you used any units like this before?
