1. INTRODUCTION Thank you for purchasing the KISAE Ultimate Battery Charger. With our state of the art, easy to use design, this product will offer you reliable service by 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 current (as per the setting) until the battery reaches its selectable Constant Voltage (CV) values. In this step, around 80-90% of the battery is recovered. Stage 2 – Constant Voltage (CV mode): With the charger voltage held steady, the remaining 10-20% of the battery is replenished with the charger allowing the current to taper off as the battery approaches full charge.
- Page 8 Choose the Current Setting for GEL/AGM/Flooded Battery Type The Bulk/Absorption (Bulk/Abs) and Absorption-Float (Abs-Float) Stage current settings are based on the House Battery Bank size. Typically, and for maximum lifespan of the sealed and non-sealed lead acid battery banks, it is recommended the maximum Bulk/Abs (“H”) current setting should not be more than 1/5 of its total capacity in Ah (e.g.
- Page 9 There are 6 user selectable settings for the DC Charger. Choose the appropriate setting that fits the needs: P1 (Alternator Input with Ignition Start signal as high priority): The unit house battery will be charged from Alternator Input when ignition start signal is provided and is in operating range. If Ignition Start signal is not provided or if Alternator Input is out of operating range, the house battery will switch to charge from Solar Input if it is available and in operating range.

Page 10: Installing The Charger
Note: This diagram is for reference only. No cables, fuse/breakers, batteries, or solar panels are supplied with this unit. 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: Chassis Ground Stud Connection: DANGER: The unit chassis has to be grounded properly. Never operate the Charger without proper grounding. Failure to do so will result in death or serious injury. Ground connection to the charger must comply with all local and application-specific codes and ordinances.
- Page 12 • Connect the solar array’s positive terminals to the unit’s CH2 “+” port and the negative terminal to the unit’s “Common Ground”. • Tighten all the bolts of the charger terminals to 4.0-5.0 N-m (35-45 lb-in) of torque. Do not over-tighten as this may result in damage to the charger.

5. UNIT OPERATION Unit ON/OFF There are three ways to turn ON the unit: • Using the unit Power push button switch located on the main unit and on the Display Panel: Press and hold the green Power push button switch on the main unit or ‘Power’ push button switch on the Display Panel for approximately one second to activate the charger. - Page 14 Note B: During the 3 minutes charging process, if the measured CH3 terminal voltage drops below the Under Voltage de- rating voltage (11.5V for a 12V Input system or 23V for a 24V Input system), the charger will start to de-rate the output current.
- Page 15 Trickle Charge Alternator battery (CH3) by Solar Power (CH2) ‘STC’ This unit comes with a unique reverse charging feature that uses CH2 Solar Power to trickle charge the Alternator battery connected to CH3. This function will only work with P4 (Solar Input Only) setting.
- Page 16 Understanding the Display function during normal operation Digital Display Display shows House battery’s battery information voltage (V), charging current (A), charging status (BUL – Bulk stage, Flo – Float stage) Solid: PV input CH2 is charging the house battery Flashing: CH2 is in standby, PV input CH2 is available and is in operating range. The house battery is charging from the other channel Off: CH2 is out of operating range or is not connected.
- Page 17 Understanding Three-Stage (Mode 3), Two-Stage (Mode 2) Charging for GEL, AGM, Flooded battery & Program Mode battery The Three-Stage Charging (Mode 3) consists of Bulk, Absorption and Float stages. During the Bulk stage, the house battery (on CH1) accepts the maximum constant current from the charger as per the setting.
