NOTE: THE BATTERY BANK MUST BE FULLY CHARGED TO PERFORM THIS TEST, AND THE DIVERT
LIGHT MUST BE OFF LONGER THAN 10 SECONDS AT A TIME. IF THE DIVERT LIGHT IS NOT OFF LESS
THAN 10 SECONDS, COVER SOME OF THE SOLAR PANEL(S) WITH A BLANKET OR CARDBOARD TO
SLOW THE CHARGE RATE.
All Flexcharge controllers are 100% tested and calibrated at the factory.
a) Connect an accurate digital voltmeter on the terminals of the battery you are charging.
b) If you are only checking the unit, skip this step, and step "d". Turn the adjustment most of the
way towards "+". The dot in the case near the adjustment is the factory setting of 2.375V per cell .

c) Watch the voltmeter for the highest voltage you wish the batteries to charge to.
d) SLOWLY turn the adjustment towards "- " until the DIVERT indicator comes ON (steady red
or orange).
e) Allow the controller to cycle a few times while watching the voltmeter, and fine tuning the
adjustment for the exact upper switch voltage you desire. Remember the controller will
switch ON and OFF (Charge to Divert then back to Charge) while you are performing this test,
and if it is switching too fast your voltmeter readings will be inaccurate which could cause
you to set the controller at the wrong voltage.
Easier Calibration Method
Note: The peak voltage setting on the NC25A is set to 2.375V per cell (14.25V for 12V systems only) at
the factory. This voltage setting is ideal for sealed gel batteries that recommend a 14.10V constant
voltage setting (see the charge process graph). The factory setting will also work with vented lead acid
and AGM batteries, however setting the peak voltage at 14.35V will give the batteries a more active
charge. You may use the method described in step 6, or an easier way may be to start your engine,
and allow the engine alternator to charge your batteries up to about 14.4 volts. Then simply turn the
adjustment on the NC25A towards "+" until the DIVERT light turns OFF then slowly turn it back until the
DIVERT light comes ON. The NC25 will now regulate the battery voltage at the same voltage as your
engine alternator, which is usually about 14.4V
Coat the battery's terminals with battery terminal grease to prevent future problems caused by
corrosion.
NC25A controllers are available for 12, 24, 36, 48 volt systems with charging capacities of, 60 & 100
amperes. Special order units with 60 ampere up to 2000 ampere charging capacities.
