That's the price to the installer. They'll mark it up, and then you have the necessary accessories and installation.

This looks more like a $6,000-$8,000 item once it's all up and running. Gonna have to run some math here to figure out the ROI.

Yeah this doesn't factor in Solar Panel Costs and the cost to install this power pack.

I'm intrigued at the backup possibilities, because we live in a forested area of the northeast where outages are common during storms. But at 3Kw a single unit isn't large enough to power our entire home, and I didn't see a figure for how long it can operate at peak load. If I need two then we're getting closer to the cost of a natural gas fired generator. This analysis, of course, is completely ignoring the environmental benefits.

I thought he said the wall unit was 10 kwh?

EDIT: Unless you mean it's limited to a 3 kw power draw - looks like it's 3.3 peak and 2 continuous.

can we just try living without electricity for 2 days? millions of humans did it for hundreds of years prior to us and they managed just fine

During hurricane Sandy our family was without power for 12 days. What's the longest you've gone?

10kWh and the details will be forthcoming I am sure.

3kW is the power, 10kWh is the energy. Your 10kWh battery would discharge in 3h20min at peak power.

Or, you could listen to music on your 250W sound system for 40h.

My power bill is rarely more than $60/mo. ROI just isn't going to happen. Am I missing the point of this product?
