New Sump pumps save power..

Found these new 1/3 HP pumps that only use about 300 watts..

Basement Watchdog BW1033 - 1/3 HP Submersible Sump Pump

Since I was adding 3 new sump pumps, I looked around for some that
wouldn't be power hogs. I should be able to fire all these up for less than 1kW..

3200 GPH is about 53 gallons a minute. So, no problem keeping up..

The float & control is separate from the pump (for easy replacement)
and has a 10-12 second ON delay after the float drops.
Meaning it's going to get down to the bottom of the barrel..

~~~

I've got a little 12VDC to 120VAC inverter that has:
Maximum Continuous Power 400W
Surge Capability( Peak Power) 800W

I wonder if it has the guts to start up and run one of these little 1/3HP pumps?

I'm thinking about using the two big LA 12V batteries that I have on my solar chargers..

Humm,
