I probably wouldn't leave the terminals exposed, but otherwise yes. Some of the pre-packaged inverter systems actually store the batteries inside the unit, so you'd be covered there. If you were cobbling your own system together from separate components, there are battery boxes you can use, and they can be secured closed with straps.I've seen the option for an inverter and marine battery. Are those child safe to leave connected at all times (setup so that power from the wall outlet runs through the inverter to the pump when power is working, and switches automatically to the backup when the power goes out)?It should work, but make sure you get one that's large enough. A 1/2 hp sump pump will draw around 15 amps (~ 1,700 W) at startup, and just under 9 amps (~1,000 W) while running.Anyone here use an EcoFlow or Jackery battery backup for a sump? I think Anker has similar items, too.
For example, the Jackery Explorer 2000, based on spec, should be able to handle such a pump, and manage around 2 hours of pump runtime on a full charge. Which is probably 4+ hours of total elapsed time even in a heavy storm, more like a day in good weather.
Do note that a traditional deep cycle lead acid battery will provide significantly longer run protection time. Mine will manage a little over a day during a heavy storm, or several weeks in good weather. That may or may not be a concern.
