Ah rating as shown. If a smaller size battery bank is used, set the current rating to a lower value to match with the battery bank size. Normally, the minimum battery bank capacity is based on a C5 rating of the battery for charging. DMT1230 Current Setting (“h”) Battery Bank Size...
5A/7A/10A 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.

Recommended Fuse Protection From Alternator Battery 50 amp (DMT1230) or 70 amp (DMT1250) Fuse or Circuit Breaker no greater than 20cm from source battery PLEASE NOTE: Automatic re-settable circuit breakers are NOT recommended. From Solar Panels Fusing recommended no greater than 20cm from input to DC2DC+ Charger.
Over Voltage Recovery 15.5V Input Battery System Reset Voltage < 7V < 7V (Note C) Maximum Input Current DMT1230 DMT1230: 30A DMT1230: 30A DMT1250: 50A DMT1250: 50A Note A: When the battery is charging through CH3 with normal operation (not through Ignition or override setting), the charger will charge for 3 minutes, it will then rest for 5 seconds to verify the Input voltage.

“overdrive” the MPPT controller. Please note that doing this is partially an economic decision. 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). On cloudy (or intermittent sunny) days there will be little or no power shaving and the extra power will serve the battery well with more energy harvest earlier and later in the day.

CH2 icon flashes when the input voltage is above the Flashing Voltage (> 14.5V) and it is not the source to charge the battery. It will change to solid when it becomes the source to charge the battery. During normal operation, every time when the ‘INFO’ button is pressed once, the display will scroll through and show ‘CH1’, ‘CH2 &...

more than 5 seconds to force the charger into Equalize Mode and it will start equalizing the flooded battery. Please note: the battery has to be set to ‘Flooded’ battery type in order to have this function activated. • During the charger Setup Menu, this button is used to change to the next available setting. •...

greater than 2.5Vdc. Re-charging a dead battery requires extreme care and attention. It is best to re-charge using short frequent cycles rather than one long bulk cycle. Battery damage or failure may occur if the battery is discharged so deeply. Understanding the Display 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...
• If the Batteries/Terminals are still cool or only warm, you may have a bad temp sensor. Unplug the temp sensor and call KISAE. CH1 Output Short Circuit This means there is a Short Circuit on the DC output to your Main/House battery.
