5/7/10 Note: The battery will start the full recharge cycle again when the battery terminal voltage drops to 13.3Vdc on DMT1230/DMT1250, and 26.6Vdc on DMT2430. If a DC load is always ON and connected to the battery bank, a higher Absorption-Float charging current is recommended.

4. INSTALLING THE CHARGER WARNING: KISAE Technology recommends that all wiring be done by a certified technician or electrician to ensure adherence to the applicable electrical safety wiring regulations and installation codes. Failure to follow these instructions can damage the unit and could also result in personal injury or loss of life.

You can install more power than the controller can use and this will contribute to better power availability. KISAE suggests a total maximum overdrive of 20% (total 600w). The extra solar panel power can compensate for cloudy (or intermittent sunny) days and around the dawn and sunset of all the days, so as to harvest more solar energy.

Digital Display • During the charging process, the display shows ‘CH1’ charging voltage, current, and status repeatedly, and ‘CH2’ or ‘CH3’ is solid to indicate the recent active input source. If the other input channel (‘CH3’ or ‘CH2’ respectively) is available and its voltage is above its corresponding ‘Start- Up”...

The MPPT Solar function may provide enough time for Equalization, but the best recommendation will be using an AC powered battery charger. KISAE does manufacture a line of smart AC battery chargers, please consult www.kisaepower.com.

1) For DMT1230, 1250 using CH 2 (Solar Array/Panel): Turn unit off. Use a proper jumper to temporary connected CH2 “+” to Ch 1 “+”. Remove the jumper when CH 1 is above the unit start up voltage (8Vdc) and restart the unit.

CH1 High Input Voltage Shutdown This means the unit has detected that the CH1 Main/House battery has gone above 16.0V/32V on DMT1230-DMT1250 / DMT2430 respectively. This error will clear once the input has dropped below 15.5V/31V respectively. This may be due to charging from another charging source (i.e. Another solar controller or AC battery charger) with either an excessively higher voltage regulation setting or a malfunction.
