We’ve done one, have one in the shop ready to go, and another on contract. Great solution for future expansion and clean installation. All mods are in parallel, but installation (with adapter cord) is end to end. No main inverter, no DC disconnect, no service or “grouped” AC disconnect required. It’s just one (or more) branch circuit to a 15A DP breaker. We’ve estimated that for systems <2.5 kW it’s more cost effective, than using a string inverter. That’s with no shading. If you have partial shading or different orientations the cost-effectiveness improves dramatically for larger systems. <BR>
<BR>
Our inspectors want a partial-cover array inspection (to check inverter listing and mounting), which is a bit of a hassle to arrange. Hopefully that will ease up once they see a few installs.<BR>
<BR>
Enphase gets the customer with the web-based, subscription, system monitoring. For small systems the production will barely cover the base cost + annual fee (free for the first year).<BR>
