A: First, what is Hyper VOC?
Hyper VOC refers to the non-operative VOC safety zone over and above the maximum input voltage.
Your classic charge controller has this safety feature (shut off) to prevent damage to your system.
This indicates that the input voltage has exceeded the operational voltage of the Classic. If this is happening now and then on rare occasions when it is really cold, then it is normal. If this is
happening all the time this indicates the PV array was wired for too high a voltage. Contact your solar installer.
Prevention is key to this, please also feel free to use our String sizing tool on our website to help calculate this in your system!
Notes - see below for our classic charge controllers range of on operational Hyper VOC ranges
at 12Volt battery bank
CLASSIC 250 over voltage is at 262Volts
CLASSIC 200 over voltage is at 212Volts
CLASSIC 150 over voltage is at 162Volts
at 24Volt battery bank
CLASSIC 250 over voltage at 274Volts
CLASSIC 200 over voltage at 224Volts
CLASSIC 150 over voltage at 174Volts
at 48Volt battery bank
CLASSIC 250 over voltage at 298Volts
CLASSIC 200 over voltage at 248Volts
