Thanks for all the time and effort in this thread. I'm trying to do this right now.
I have a 12v 7a battery connected to the jumps, and when I connect it, there is a flashing red+blue light at the reset button of the inverter.
I turned on the general duty switch, inverter breakers, and DC disconnect switches on both SunPower inverters then turned on PW.
PW flashed green leds for a few seconds and now it's solid green.
Inverters still say waiting for grid voltage. How long should this take? Anythiughts to troubleshoot?
Thanks
