MK4+ Hybrid Charge Controller User Manual

braking function.
So, unlike typical systems, the MK4+ has 3 set-points: 1) a dump-load set
point, where it begins its step-less PWM regulation and constant-voltage
charging; 2) A full-charge set-point, where it recognizes a full charge, stops
charging and begins 100% dump loading; 3) An over-current/over-voltage
set-point, which will automatically brake the wind generator rotor, which also
stops the charging.
Two DC Output Modes (for controlling other loads like lights, etc):
If you do not intend to use your controller as a lighting controller, you may skip
this section, but please note that when this user manual refers to “load(s)” it is
referring to the loads it is controlling with this function, rather than other
external loads not being controlled directly by this controller function. Note
that for the light-sensitive (dusk-to-dawn) DC load control functions to work,
you must also have a solar panel attached to the controller.
There are two separate DC outputs on the controller, which we reference as
Output #1 and Output #2. For each of the two outputs the user can set three
output control modes using the LCD and keypad buttons: 1) The dusk-to-dawn
function - where the lights come on, and go off, based on ambient light level
sensing from an attached PV panel); 2) Dusk-on, elapsed time off - where the
off time is based on an elapsed on- time; 3) Constant on
– the lights stay on for
24 hours or until the battery is low.
