AC200MAX and water pump

Hello, I would buy an AC200MAX to power a WATER PUMP in my house.
At the moment the pump is connected to the home electrical system, but sometimes the power goes out for works or something else. If the water pump has no power, there is no water in my house.
So the idea was to connect the AC200MAX to wall charger and the water pump to the AC200MAX. In next months the idea is to connect a couple of photovoltaic panel to the AC200MAX for total of 800W, so the water pump maybe covered totally by the AC200MAX through PV panels.
So the question is…is it possible to leave always connected the AC200MAX to the wall charge and use it for the pump, and in the future wall charger and PV panels?
Here there is the datasheet of the pump too.
Thanks a lot!

The pump specs you list show it as requiring 230 volts AC and the AC200 Max is limited to 120 volt AC output
