User Manual

NOTE: The equalisation function although included in the ePOWER DC2DC+ 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.
