To start equalizing the batteries:
◆ On the device Setup menu, highlight Equalize and select Enabled.
Using Charger Block
The Charger Block feature halts charging for a period of time each day. This
period of time is defined by the Chg Block Start and Chg 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 Chg Block Start and Chg Block
Stop, AC 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 occurs even if the batteries discharge below the ReCharge
Volts setting. However, a Solar Charge Controller may charge batteries during
the Charger Block period.
If the charger is operating (that is, in Float, Absorption, Bulk, or Equalize stage) at
the Chg Block Start time, charging stops immediately and the charger enters
an idle state identical to No Float (see “Two-Stage” on page 4–17). When the
Charger Block period is over, the charger does not resume the charge stage that
Chg Block Start interrupted. Instead, if the batteries are above the ReCharge
Volts setting, the charger remains idle. If the battery voltage falls below the
ReCharge Volts setting during the Charger Block period, the Conext SW
Inverter/Charger begins a new charge cycle with the Bulk stage after the
Charger Block period has expired (at the Chg Block Stop time).
NOTE: Only flooded or vented batteries should be equalize-charged.
Hydrogen and oxygen gases are produced when batteries are equalize-
charged. See warning below.
WARNING
EXPLOSION HAZARD
Provide adequate ventilation for the battery and remove all sources of ignition
to reduce the risk of explosion.
Failure to follow these instructions can result in death or serious injury.
IMPORTANT: In a system where more than one device is capable of equalizing
batteries (such as a system including multiple Conext SW units and Solar Charge
Controllers), there is no system-wide equalization command for all devices. To
equalize with multiple devices, each would have to be enabled individually.
Alternatively, equalization can be performed using only one device. During the
equalization process, one device applies the equalization charge while the other
devices continue to operate in synchronized charge mode, typically in float
(three-stage charging) or no-float (two-stage charging).
