abd7 Posted March 30, 2022 Posted March 30, 2022 (edited) To prevent PCs restarting during the slight dip in power as the inverter switches between SUB etc, we have multiple small ups on our pcs. Say there's 10 of these. The input current rating on the sticker shows 10a each. That's 2.4kw each, 24kw just on the UPSs. Although the devices behind the upss are rated around 400w max. What would be a reasonable kw value to use in calculating loads for the inverters, obviously 24kw is way too much Edited March 30, 2022 by Hansa Quote
P1000 Posted March 31, 2022 Posted March 31, 2022 Personally, I would get an inverter that does not require the use of UPSs. Failing that, the max load of the devices behind the UPSs plus the max charging load of all UPSs. Quote
Bobster. Posted March 31, 2022 Posted March 31, 2022 Can you not run 2 PCs off a single UPS. That way you cut the load you have to deal with by 50%? Then wait until load shedding starts again and sell the others - demand and price go up when Eskom starts shedding. Quote
