Here’s my PW2+ installation. Note that the new PW2+ Does allow the solar array to do net-metering (back feeding the grid) while supplying power to both home use and battery storage.
Looks great, thanks for sharing! Do you know if stacking PWs is allowed in your locality? Did your installation crew mention anything about stacking a PW on top of the PW+? I wonder if your two PWs were installed separately by design, or whether the crew was just unfamiliar with how they're meant to be stacked.
