Fridge nameplate is 11.6A but my kill-a-watt measures 0.9-1.0A when running.
The SUA1000XL easily started the fridge, but oddly only ran for three hours before having a low battery warning. This matches the 100W run graph with no external batteries connected. I inspected the external 35AH battery pair and discovered the inline 25A fuse I added was blown. Evidently the 35AH pair got the compressor started just as the fuse blew, and it continued running on the 18AH pair.
I inspected the APC inline fuse on the 18AH pair and it was 100A? No way the battery wires are rated for that. Also at 25V = 2500W on a 800W UPS? Now I am wondering what I should fuse the 35AH pair. Might move the 100A fuse to the 35AH pair and fuse the 18AH pair at 50A.
I inspected the inline fuse on my SUA3000XL and it was 140A? At 50V = 7000W on a 2600W UPS? APC sure isn't shy about fusing their XL UPS’s.
