Putting together an emergency backup with a UPS takes a lot of research. Converters come in vaious types. First you have to take a look at what your trying to power. Look at the your pump and determine if it's AC or DC powered. All AC powered pumps have trouble with the step wave frequency that ordinary converters put out. Once you have figured out which type you need, you then need to figure out how big and what type of battery you need to power it. You will also want something that has a UPS and charger built into it as well. This is a complicated and somewhat difficult task (unless your an electrician or engineer) and it will take you a while to get all the info you need. I put mine together years ago so there are probably better products out there for you. I would do a search here using key words like UPS, converter charger, and true sine wave. I know the calculation for determining how big of a battery you will need is here somewhere also. Take your time and look at all the options. There are some good DIY plans to be found here in the forums too.
