865-1030 (Xantrex XW MPPT Charge Controller)

865-1030.01_05_00.BN0006

1. The charge algorithm was modified. See the accompanying diagram that

shows precisely how the algorithm operates now:

Figure 1 Xantrex XW-MPPT60-150 Charge State Diagram

Notes:

1) When the charge cycle is interrupted, the charger will restart charging at the beginning of the multi-stage

algorithm.

2) Exit Current Threshold can be effectively disabled by programming the amp hour capacity to zero. In this

case, Absorption will only exit once the Max Absorption timer expires.

3) Charge current during Equalize state (optional state not shown here) is normally limited to 10% of the

programmed amp hour capacity setting. If this setting is programmed to zero Ah, the charge current during

equalize is instead limited to whatever is programmed for the max current limit of the unit (default is 60A).

4) Synchronized charge states are active when more than one charging device (MPPT or Inv/Chgr) is connected

in the system via the Xanbus network.

i. The first unit to enter Bulk, causes all other chargers to enter Bulk.

ii. The first unit to enter Absorption, causes all other units to enter Absorption.

iii. The last unit that is ready to exit Absorption, triggers all units to exit Absorption and enter Float
