Page 6: Introduction
1. INTRODUCTION Thank you for purchasing the KISAE 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, boat, RV, caravan, 4WD or commercial vehicle. - Page 7 WARNING: FIRE HAZARD. When choosing the Lithium Battery type, you can set to a wide range of charge/float voltages. Please consult the battery manufacturer for the values. Using the wrong voltage setting may overcharge and damage the battery and may cause a fire. DMT12100 Charging Voltage Setting (See Note 1 for DMT2450) Battery Type Bulk/Absorption...

- Page 9 House Battery Charging Mechanism Setting There are 5 user selectable settings. Select the right setting based on the scenario listed below: P1 (Solar Priority): The unit house battery will be charged from Solar Input (CH2) as priority and Alternator Input (CH3) as second priority. If Solar Input is not available, the house battery will switch to charge from Alternator Input if available and in operating range.

Page 10: Installing The Charger
Local rules and regulations should be followed when installing this unit. 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. - Page 11 Wiring the Charger: DC Inputs and Output Wiring (CH3, CH2, CH1 and Common Ground): WARNING: The DC wiring used must be of an appropriate size. An individual over-current protection device such as a fuse or circuit breaker usually within 7 inches (17.8cm) of each battery bank is required.

Page 13: Unit Operation
5. UNIT OPERATION Unit ON/OFF There are three ways to turn ON the unit: • Using the unit ‘On/Off’ switch located on the “Remote” panel: Press and hold the ‘On/Off’ switch for a second to turn ON the charger. When the charger is not in use, press and hold the ‘On/Off’... - Page 14 Operating from a PV Solar Array/ Panel (CH2) Normal Operation PV Solar Array/Panel (CH2) PV Input Voltage Range 14.5 - 55V PV Input Under Voltage Shutdown < 14.5V PV Input Under Voltage Recovery 15.0V PV Input Over Voltage Shutdown > 55.0V ≤...
- Page 15 Understanding the Silent Mode Silent Mode is in used when a quiet environment is required. When this function is activated, the ‘Auto’ icon on the display will turn ON. The fan speed will be reduced to 20% of the normal operation and the charging current will be reduced to a maximum of 25A.
- Page 16 Understanding the Digital Display Function Digital Display House battery is being charged and is in Bulk charging stage House battery is being charged and is in Absorption charging stage House battery is fully charged (with Lithium battery type setting) House battery is fully charged (with GEL, FLOODED, AGM, Program battery type setting) Flashing: Equalization process is in progress Solid: Equalization process is selected and is waiting for the process to start.
- Page 17 Understanding Three-Stage (Mode 3), Two-Stage (Mode 2) Charging The Three-Stage Charging (Mode 3) consists of Bulk, Absorption and Float stages. During the Bulk stage, the house battery (on CH 1) accepts the maximum constant current from the charger as per the setting.
- Page 18 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 19 Understanding the Display and Error Warning Code Codes will show on the display when either a function or internal warning / fault, such as high internal temperature or DC out-of-range is detected, and the charger may shut down to protect itself until the fault has cleared.
- Page 20 CH1 High Input Voltage Shutdown This means the unit has detected that the CH1 Main/House battery has gone above 16.0V on DMT12100 or 32V on DMT2450. This error will clear once the input has dropped below 15.5V on DMT12100 or 31V on DMT2450.
