User Manual

Note 3: Charger is acting as a power supply with selected constant output voltage and
preset maximum output current.
NOTE: The equalisation function although included in the ePOWER DC2DC 24V will rarely
be used. To activate, the battery bank must be in oat, and manually activated. A typical
drive will not be long enough for the DC2DC function to complete the process. The MPPT
Solar function may provide enough time for Equalisation, but the best recommendation
will be an AC powered battery charger.
Battery Bank Size Recommendation
The battery charging current rating is based on the battery size. The battery bank should
meet the minimum 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.

5. INSTALLING THE CHARGER
WARNING
Enerdrive recommends that all wiring be done by a skilled technician to ensure adherence
to the best practice standards for on-board DC electrical installations. Failure to follow
these instructions can damage the unit and could also result in personal injury or loss
