I would recommend them.

Never had a problem with them. You need either a control card or a master
inverter in each rack.
I prefer the control card so all the inverter modules are the same.
I also like the transfer switch so it will cut over to commercial power if the
inverter rack dies or if you need to shut it down for some reason.
1000 watts per module. Add as many modules as you need. Up to 20kW for single
phase.
Sine wave.
I note that that particular rack I gave the link to on ebay is 24 VDC.
They do not charge the batteries.
I use Eltek for battery charging. If you keep your eye peeled you can get some
bargains.
Just bought a whole Eltek shelf for about $495 yesterday off of Ebay.

Chuck, Would you recommend them? How solid are they? What is the wattage of the
configuration on ebay? Do they charge the batteries?
