You would think that this is a well-designed system, WRONG! This conguration will
be safe from exploding into a ball of ames, but the VOC is so high, chances are the
panels may not warm up enough during the day to drop below 150V. Remember the
Classic will not turn on when the PV input voltage is above 150V. Since the nominal
25
O
C VOC was already 147.6V, you can see it won’t take much cold weather to go
over 150V. Heck you probably wouldn’t even need a sweater, but your system will
not be charging due to cold temperature.
The charts below display the upper maximum HyperVOC limit based on the nominal battery
bank voltage.
Important: HyperVOC is the maximum input voltage plus nominal battery voltage. The maxi-
mum nominal battery bank voltage allowable is 48V, even if the battery bank being used is
higher than 48V.
