lowest $/W grid-tie string inverter?

[nerdralph]

So far the best price I've found is on Solis inverters. Growatt seems to be another low-cost manufacturer, but I haven't received a pricelist yet. Is there any other low-cost producers of 5-7kW split phase 240V/60Hz grid-tie inverters that are certified for use in the US & Canada?

I don't know how it will compare to those, but check out the price on APSystems QS1 quad microinverters. They are sold by many dealers and prices vary, so you can do well by shopping around.

If your shopping based on price alone you're on a fool's errand.

When it comes to inverters, there are three criteria to shop by:
1) Reliability
2) Reliability
3) Reliability

I don't want to put electronics on the roof. I'm only interested in string inverters that mount on the wall.
