Zendure Ace 1500 is an AC control unit with no battery of its own: on its own it stores no energy, and it always needs one or more Zendure AB1000 or AB2000 batteries connected separately to work, both as a portable power station outdoors and, together with SolarFlow, as the control unit of a balcony storage system. When power fails it switches to emergency power so fast that connected appliances don't notice.
During an outage it prioritizes the fridge or any other directly connected appliance, to keep it running continuously rather than intermittently. It also charges from a solar panel, not only from the home outlet, though charging from the outlet stays relatively slow. How much power it can actually deliver depends on how many batteries are connected: with a single battery from the smaller series it stays below its maximum, and reaching the full amount needs a second battery, or one from the larger series.
It's built for anyone who already has, or is about to buy, an AB1000 or AB2000 battery and is looking for the control unit that makes it work while camping or on the balcony: not for anyone looking for a device that stores energy on its own, straight out of the box.
Highest technical score among the 7 sheets in the Compact category (outlet-sized tier): 86/100.

The rest of the data comes from one page on the manufacturer's site, cited row by row in the table above.
A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.
These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.
Chosen by the declared use tier and footprint, not by price: we don't publish prices.
