A 12V backup system is worthwhile in case of pump failure though the battery won’t last long nor will the pump be high volume in case of big rain.
A smallish generator will keep your 120V pump system running for quite a while and you can rotate the power to other systems like fridge, TV’s or window A/C units if the rains let up.

Don’t run it indoors!

I’m thinking I want something that gives me piece of mind. When our pit filled, it took several hours so I think if I put in a two battery system, that would give me ample time if the pump isn’t running all the time. A generator with cutover is fairly expensive solution and having a portable generator does me no good if I’m not home. Thanks for the feedback.
