I think of it as having the right power elements to drive the pv.
A decent 4 bay charger plus two rotations of batteries can be had for less than the price of the pv. I'm talking LG/Samsung/Sony batteries, Xtar charger.
If a person doesn't already have the proper batteries and charger, isn't willing to invest the $ to get good, safe, power equipment, they are a bad candidate to be using such a device.
The sales literature for the unit should be very clear about this, I expect it will be.
