From 1 Ah to 2000 Ah. It all depends on how long it needs to operate from the UPS. Example calculation here.

Inside there is a 4A fuse, will anything happen? This connector can be connected to a battery directly, without an uninterruptible power supply. "It ensures normal operation with the TUNZE® power supply, but in case of a power outage, it can also automatically connect the battery or another source of direct current."

Who will charge the battery? Manually charging and monitoring? Nothing will happen with the fuse.

I will provide for myself. I have an inverter, but I don't want to put it in the room because the fan is noisy. In the SAM (it's behind the wall), the inverter can only be placed on its end, which is inconvenient. It's better to supply 12 or 24 V directly than through the inverter (220-12 (24)), which consumes a lot of energy for its fan when operating from the battery, and will use as much energy as the pump. Or am I missing something?

Well, the fan consumes about ten times less than the pump, so it's insignificant. One person wrote that after experiments, they ended up powering it from the UPS. Directly from the battery doesn't work very well.

If it's through the UPS, then the connector is not needed, right?
