Page 5: Introduction
1. INTRODUCTION Thank you for purchasing the KISAE Abso DC to DC Battery Charger. With our state of the art, easy to use design, this product will offer you reliable service for providing a multi-stage, multi-input battery charger to charge the different types of batteries you have installed in either your home, boats, RV caravan, 4WD or commercial vehicle. - Page 6 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.
- Page 7 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. - Page 9 Recommended Cable Length, Size and Fuse Protection: Recommended Fuse/Circuit Breaker Size, Wire Length and Size Unit Connection DMT1230, 2430 DMT1250 CH 1 House Battery Bank 40A, <5 ft, AWG #8 / 10mm 60A, <5 ft, AWG #6 / 16mm CH 2 Solar Array/Panel 12V/300W: 20A, <20 ft, AWG #12 / 4mm...

Page 10: Unit Operation
Input Battery System Reset Voltage (Note D) < 7V < 7V Maximum Input Current (CH3) DMT1230/2430: 30A DMT1230/2430: 30A DMT1250: 50A DMT1250: 50A Note A: When the battery is charging through CH3 with normal operation (not through either manual or automatic override setting), the charger will charge for 3 minutes, it will then rest for 5 seconds to verify the CH3 Input voltage. - Page 11 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.
- Page 12 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”...
- Page 13 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.
- Page 14 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.
- Page 15 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.
