I'm guessing it's an azimuth Wattsun, given that only one linear actuator is visible, and the earlier tilt'n'roll had two. I sent William a 2009 AZ-125 manual in pdf. Allan On 7/21/2020 8:37 PM, Dave Angelini Offgrid Solar wrote: Not enough resolution to id. Best guess is pre AZ-125 which is

Friends: If anyone has a manual for this tracker, I would really be grateful to receive it. Pretty sure it’s some form of Wattsun tracker. TIA William Miller www.millersolar.com___ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.

I'm not a fan of this strategy. What happens when the coil fails? It's not a failsafe solution IMO. Jason Szumlanski On Tue, Jul 21, 2020 at 10:52 AM wrote: > Larry, > > Connect the coil of a 240 VAC contactor to the output of the generator > circuit. Have the contacts of the relay break the

Whoever drew that up made it look like the generator is the common pole. I know what they were getting at, but it's a pretty poor way of depicting it. On Mon, Jul 20, 2020 at 6:15 PM la...@starlightsolar.com < la...@starlightsolar.com> wrote: > This, from a Nov 03, 2017 Powerwall 2 document, ma

Sorry - Automatic Generator Start. What I'm wondering now is how does it manage PV inverter output and generator power operating simultaneously? I think they are saying the generator will not automatically start if there is PV inverter input output present. If that is the case, what happens when t

Jay, The Tesla Gateway has a 12v input terminal for boot up. To startup my off grid Powerwall we wired in a 12V power supply to the input terminals and plugged the other side into a grid-connected outlet. Some version of this is part of their off grid process. We’ve been running a reasonable

Connecting a generator output to the inverter output has the potential to damage the generator control board. Another way to go is to put a diode on the output of the generator and parallel it into the DC input to the GT inverter. Preferably you’d want a larger generator than the GT inverter.
