It is now available, for all GV-5 and GV-5-MOD controllers, the new Genasun Overdrive (GO) feature. This feature can be included in the firmware with the Custom Voltage (CV) version, part numbers GV-5-Pb-CV, GV-5-Li-CV, and GV-5-MOD-CV. This feature is in addition to all the other Genasun capabilities that make the GV-5/-MOD unique products in the off-grid market.
The GV-5 and GV-5-MOD are still rated with a max output current of 5 A, but GO allows the charge controller to be paired safely with panels/arrays providing up to 15 A of current without reducing the charge controller’s efficiency or performance. Oversizing your panels/array will ensure more energy delivery to the battery when you need it most, for example, during months with lower solar irradiations or in the early and late hours of the day.
Most of the charge controllers on the market can shave power off oversized solar panels for a limited period by over-warming the controller, which affects their performance and longevity. GO allows the GV-5 and GV-5-MOD to handle “unlimited power” and keep the controller in a safe condition and operating at full efficiency. While this means that larger panels will be significantly limited, there are situations in which GO can provide important advantages:
With the introduction of Genasun Overdrive, the GV-5 and GV-5-MOD monitor the input current every 5 ms, slightly increasing its self-consumption to 190 uA, which remains the lowest self-consumption on the market by far. A few other changes have been applied to the manual with the introduction of GO, as well. For example, the LED status indicators work somewhat differently in units with the GO update. Please refer to the latest manual for more details.
