HyperVOC ™ Origins
HyperVOC can be useful in overcoming an industry shortcoming in charging 48 volt battery‘s with
standard panels. For example let‘s take a sample system with Solar World 165‘s that have a VOC of
44.1vdc. The industry has limited us to 2 of these panels in series making it hard to charge a 48vdc battery
on hot summer days. With the Classic we designed in Hyper VOC to allow you to run 3 of these in series.
3 panels at 44.1vdc will give you a total VOC of 132.3vdc. When temperature compensated for cold
climates to 125% gives you 165vdc. This is above the maximum safe limits for most controllers but falls
well into the Hyper VOC range of the Classic. We do have to use Hyper VOC wisely though if we abuse
it the Controller will never wake up in colder weather.
