CV 24/48-25 BE

Application

Used to connect a 24V windmill to a 48V battery bank. The most common situation is when a user upgrades from a 24V system to a 48V system and still wants to use the existing 24V windmill.

Basic Operation

The 24V windmill will connect to the midpoint or 24V section of the 48V battery. The windmill will operate using the current windmill charge controller or dump load regulator as if connected to a regular 24V battery. The CV 24/48-25BE controller hooks up across the 48V battery as well as the 24V midpoint. When the windmill puts power into the 24V section of the battery the CV unit will detect it and transfer power to the upper section at 48V making sure that the battery is charged equally. While operating similarly to an EQ or battery equalizer, the CV only works in one direction or boost mode.
