Multi-Stage Charging Process

The charging cycle is a multi-stage process. Whenever qualified AC power is

present at the AC1 or AC2 input, power runs through to the connected load and

begins charging the batteries in parallel.

NOTES:

When the charge cycle is interrupted, the charger will restart charging at the

beginning of the multi-stage algorithm.

Note: Using the Conext SCP, make sure that every XW+ unit in the multi-unit

configuration is set to Charger = Enabled under the Setup menu for each

inverter.

Note: If Cascading is Enabled in SCP, the charger settings will cascade to

other Conext XW+ units with the same DC Associations. However, they will not

cascade to other device types such as MPPT solar charge controllers and the

Battery Monitor even if they have the same DC associations. Make sure that the

charger settings are configured correctly on the other device types.
