Connecting an uninterruptible power supply to a car inverter?

Question

Do it yourself

I put an 800w inverter on the wheelbarrow. The question arose, will it pull an uninterruptible power supply (in particular, powercom vanguard VGD-1000)? It is written on the uninterruptible power supply that the maximum that it can eat is 10A, but I wonder how much it really needs when charging?

Answer 1

Maybe it means the maximum current passing through the UPS = 10A? He can't eat that much while charging.
Battery power inside the UPS = 7A*12V=84W
On average, the battery takes 6 hours to charge, i.e. 14W/h or 14W/220V = 0.06A/h. Let's add a little to the heat loss and add the current required for the functioning of the brains of the UPS, we get A = 0.1 A or 22W.

Answer 2

and if you throw out the battery in the uninterruptible power supply and connect it to the car, then the inverter is not needed

Answer 3

From the local forum 220 in auto
, this is a continuation of the comment above

Answer 4

10A*220V=2200W

Answer 5

They wrote you correctly based on the available data, but if you don’t believe me, take an ammeter and measure the real current during the charging process.
