Your point about Romex is a good one, but hardly worth the cost of an inverter I would think... I'd have to do that math... Yes, I meant 1741, and forgot that covered standalone inverters as well... Been away from off-grid too long!
To Larry's point, I agree that the cost posted online is unworkable, but I was under the impression that dealers could get discounted pricing from what's shown online. When you look at the cost of a standard tank, microinverter, and PV, it should be much, much less.
