The cabinet is complete and simply resting on top of the barrel. I'm no cabinet maker, but it's functional.

We are due for a big storm tonight, so I thought I'd drain the barrel.

Not much sun right now - 0.0A charge from the cells. Battery voltage looks good, and we can see the pump is drawing 5.8 amps. (The display isn't burnt out, it's just how the camera captured it.)

The 50 gallon barrel was drained in 25 minutes to a sprinkler with 50' of hose. That's 2 Gallons per minute.
