Charger Block
The charger block feature halts charging on AC1 (Grid) for a period of time each day. This
period of time is defined by the Charge Block Start and Charge Block Stop
settings. In areas where the utility charges variable rates for electricity, it is preferable to
use utility power for charging only during non-peak hours. Charger block can prevent
utility power from being used for battery charging during peak billing periods.
During the time period set between Charge Block Start and Charge Block
Stop, AC1 (Grid) input continues to be passed through to the loads. Inverter operation
remains unaffected during the charger block period.
During the charger block period, no charging on AC1 occurs even if the batteries
discharge below Recharge Voltage/SoC setting. However, a generator connected to
AC2 (in the absence of utility/AC1 power) or a Conext MPPT solar charge controller may
charge batteries during the charger block period. AC priority must be set to AC2 to charge
batteries with a generator connected to AC2 during the charger block period.
If the charger is operating (that is, in float, absorption, bulk, or equalize stage) at the
Charge Block Start time, charging on AC1 stops immediately and the charger
enters an idle state identical to no float (see "Charger Settings" on page59). When the
charger block period is over, the charger does not resume the charge stage that was
interrupted. Instead, if the batteries are above the Recharge Voltage/SoC setting,
the charger remains idle.
If the battery voltage discharges below the Recharge Voltage/SoC setting during the
charger block period, the Conext XW Pro begins a new charge cycle with the bulk stage
after the charger block period has expired (atthe Charge Block Stop time).
For example, charger block is set to start at 5:00 PM and end at 8:00 PM. If the Conext
XW Pro is charging from AC1, charging stops at 5:00. When charger block ends at 8:00,
the Conext XW Pro does not automatically resume charging. The unit first measures the
battery voltage.
n If the voltage is below the Recharge Voltage setting, or if the state of charge is
below Recharge SoC, then the Conext XW Pro starts a new charge cycle from
bulk.
n If the voltage is above the Recharge Voltage setting, or if the state of charge is
above Recharge SoC, then the Conext XW Pro remains idle and continues passing
through AC to the loads.
TheConext XW Pro also keeps measuring the battery voltage as before to determine
whether to start a new charge cycle.
Peak Load Shaving (PLS)
Many utilities impose a surcharge on their customers based on the peak load used by a
facility. To reduce utility peak demand charges, the inverter can be configured (using the
Load Shave Amps setting) to help limit the maximum draw the AC loads place on the
utility. The inverter can be programmed to provide power above a specified level to avoid
the surcharge. When the utility current draw reaches the maximum level, the inverter
assists by sourcing power from the batteries to the loads.
