I have decided to go with 40%.
For my system, 16 kW, even if it is a partly cloudy day the next day, it should recharge to full status.
Only a really overcast rainy day might prevent a full recharge.
I figure if we always have at least 40%, we can likely handle a grid outage no matter when it happens.
If it is middle of the day, fine ... my system is likely at 100%.
If it is middle of the night, fine ... the sun comes up in a few hours.
Florida based, two PW2 units.
What is your Self-powered percentage set at and why?
Hopefully something to be learned from this topic by others sharing their strategy.
