All,
Someone help me understand this. A lot of the stories I read about battery storage have a disclaimer along the lines of "limited to 4-6 hours". And that longer duration storage is needed (see below article).
If someone builds a site with (for example) 100 powerpacks that all charge during the day, what is to prevent that site from discharging 20 of them for 4 hours, the next 20 for the next 4 hours, etc, and then having a total discharge period of 20 hours using lesser output versus discharging them all during the first 4 hours?
If you need 12 hours of battery discharge, just build a battery that is 3x larger and stagger the power output, right?
