Hi,
Sorry for what may be a simple question. What is the best way to manage PW when the grid is out. Specifically when to shut down PW to preserve enough power to start up inverters.
I have 3 PW 2s and we had worse case scenario a couple weeks ago and PWs were completely drained and grid was off. Solar could not generate power till grid came on.
Background:
Snow storm shut grid down in morning. I didn't have storm tracker on the night before (hard lesson learned) and the PW were at 20% when grid went off. There was no solar being generated because of snow storm and PW ran down to 0. Eventually The sun came out and panels were cleared but the PWs did not charge until grid was restored days later and inverters could come on.
If I understand other posts, my problem was because there was not enough power remaining in the PWs alone to get inverters started. I did try manually switch the PWs on and off... but that was done too late.
The situation:
-grid is off
-PWs are getting depleted (assume the draw is being managed)
-solar can not generate power to charge PWs (night time, cloudy weather or snow cover)
Question:
Is there a setting that would automatically shut down PWs to preserve enough power to later start up solar inverters. Or is this a manual step.
I know this means being without power for a short time - but this is just until solar can charge PW again. If this is manual, at what % Power should I do that. If there is a hidden reserve % - it's not enough to start my inverters. (3 PW2s, 2 inverters, 19Kw solar panels)
I hope this makes sense because I am right now looking out our window at a second snow storm that started a couple hours ago....making ice for my Gin and tonics in advance because.... priorities.
Currently PW are at 100% and I will likely manually turn off PW at some point if grid goes off. But I want to know what the right thing is to do.
I will be downloading the data to see what is shows for the outage two weeks ago.
Thx in advance for any help or gin recommendations
