Re: [RE-wrenches] Tesla Powerwalls

Jason, They announced that Tesla Direct would stop offering standalone Powerwall installs, and would only take orders for PV+Powerwall. That announcement has confused just about everyone because Tesla marketing is very LOUD and generally ignores the existence of non-Tesla certified installers

Re: [RE-wrenches] Tesla Powerwalls

Tesla continues to maintain their Certified Installer network. Tesla Direct sells direct to the consumer/homeowner in a number of geographic territories. marco On Tuesday, July 20, 2021, Jason Szumlanski < ja...@floridasolardesigngroup.com> wrote: > Didn't Tesla explicitly cut off it's dealer

Minor update, I got word from Snapnrack that: "The new protocol established with UL eliminates the need to include the wattage ranges for each module type" Still a pain and the manufacturer/model should be on the rack manufacturer list - but not down to the precise wattage - so slightly less of a

Re: [RE-wrenches] Tesla Powerwalls

Didn't Tesla explicitly cut off it's dealer network and essentially tell the world that they are only selling Powerwalls direct with purchase of PV from Tesla? I thought Powerwall was essentially dead to smaller independent dealers. Jason On Tue, Jul 20, 2021, 8:13 PM Marco Mangelsdorf wrote:

Jay Even if you that sell limit setting is low, I’d drop the grid and load up the inverter a bit, and force bulk just to be sure the CC and PV are functioning correctly. You could even amp clamp the PV strings to make sure each string is correct. Good luck! Maverick Maverick Brown Off-Grid
