Can an HF kit be connected to a 12V battery, then a second HF kit be connected to a second 12V battery, then the two batteries connected in series to yield a 24 VDC system ? Will each battery be…Continue

Harbor Freight 1200/3200 Watt Inverter shut off

The user guide indicates a low voltage alarm at 10.5VDC on the battery, with an automatic shut off at 10.0VDC. Another thread indicates battery damage will occur below 11.9-12.0 VDC. Is the HF…Continue

"short answer is no that won't work. When you series the batteries together the HF controllers will see it as a 24v battery and either they will burn out or just have a fault. Might just blow a fuse. If you are going 24v then you need a setup…"

24VDC using two 12VDC batteries

Can an HF kit be connected to a 12V battery, then a second HF kit be connected to a second 12V battery, then the two batteries connected in series to yield a 24 VDC system ? Will each battery be regulated independently by the HF controller (If this is even possible)?See More
