Wrenches This customer with an orphan PW, not to compromise the factory warranty on the batteries, it would be safest to just grid tie any additional PV and not touch the existing system from the gateway down. Jerry NABCEP PV Inspector On Fri, Apr 16, 2021, 8:38 AM Kirk Herander, VSE wrote: >

Hello, I hope this helps. I have very little PW experience, the one i was involved in had a 1741 transfer switch with grid monitoring on the mains. When the grid failed the switch would disconnect from the Grid and connect the PW to the panel or sub-panel. The PW charges from the AC source when

Hi Kirk, the maximum actual charge rate is 5kW per Powerwall. When you exceed that, or start getting full batteries, the Gateway tells the Powerwalls to frequency shift to 62-66 Hz. This takes the UL 1741 listed inverters out of the sweet spot, and they stop or curtail production. However,
