The UPS was delivered this morning. Very fast delivery, as I only ordered around 5pm yesterday.

It was 27% charged, so I fully charged it. It absorbed 1.58kWh and took just under 2hrs.
I did a FULL discharge with a load of around 650W.
It lasted about 2h50 and delivered 1.74kWh. Very good, considering battery is specced at 1.997kWh.
The fan came on very little, and I couldn't really hear it. VERY QUIET!!!
There was no alarm at 10%, only at 0%, there were 3 beeps, then it shut down.
I then charged it
without a load, started at 1100W and it reduced to 550W and then 300W and down to 0W,
within 2:15.
It absorbed 2.16kWh to fully recharge from 0%.
Again, no fan noise.
This thing is QUIET!!!!
When I compare this R20k UPS to my trolley (R26k), it's obvious my trolley will be backup no. 2, before my generator.
I can recommend this GEEWIZ UPS without any hesitation!
For the folks interested, with a fully charged battery, in UPS mode, the UPS only consumed 10W more than the load, so 10W losses.
My trolley was running at 55W losses. That's a waste of an extra R100/month.
Now if anybody can tell me where I can buy an Anderson plug, I'd appreciate it
