Item Description
The Battery Balance function is disabled by default and is
Batt_Balance
intended for use with inverters drawing power from a single
battery bank. The Battery Balance function should be
enabled when Conext XW+ units are used in multi-cluster
systems with multiple battery banks. When enabled this
feature helps balance the power draw across multiple battery
banks.
This feature is used in a multi-cluster configuration with
EXT_CONTACT
external contactor for off-grid applications. Further details
regarding the use of an external contactor can be found in
the Conext Multi-Cluster Planning Guide (document part
number: 975-0648-01-01).
This feature controls an External Transfer Switch according to
EXT_LOAD_SW
the status of the power source's AC voltage in AC1 (Grid).
When this feature is Enabled the following occurs:
•
•
When enabled, PLS (Peak Load Shave) mode is delayed by 2
PLS DLY 2h
hours to allow the MPPT solar charge controller to charge the
battery bank first, then when the timer of 2 hours expires, the
unit enters PLS mode for AC load support.
The TOV (Transient Over-voltage) disconnect feature is used
TOV_DISCNCT
for utility interconnect requirements (e.g. HECO - Hawaii
Electric company, Tariff Rule 14H - Supplemental requirement
- Transient Over-voltage fast trip).
While in sell mode, the Conext XW+ will disconnect within one
line cycle when the grid voltage is above 120% of its nominal
value.
When voltage source is qualified at AC1 port then the
AUX Port generates 0V (across JU-1 and JU-3).
When there is no voltage source qualified at AC1 port
then AUX Port generates 12V (across JU-1 and JU-3).
