Note: To comply with anti-islanding requirements, in a grid tied AC coupled system, change the AC1 Transfer Delay setting under AC Transfer Configuration to 300 seconds. Sell Block The sell block feature halts the export of energy to the grid connected to AC1 for a period of time each day.
Configuration Conext XW Pro Owner's Guide In a ‘fixed’ battery voltage system configuration, the Conext XW Pro manages the battery voltage to the Grid Support Voltage setting. This is done by converting the available DC power to AC power to support the AC loads attached to the inverter output or exports to the utility grid (AC1).
Conext XW Pro Owner's Guide Configuration 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.
Configuration Conext XW Pro Owner's Guide For PLS to be effective, all loads must be connected to the inverter. For large loads, multiple (or stacked) inverters may be required. To help the batteries supplement the power requirements of the connected load, an additional source of power (solar, wind, or hydroelectric) is recommended. The default PLS setting for Time in Float is zero. In this case, PLS is only entered/exited as programmed within the time window.
Conext XW Pro Owner's Guide Configuration When using the system for time-of-use metering, the system should be designed with a battery capacity large enough to support loads during the entire peak rate period without reaching the Low Battery Cut Out or Low Battery Cut Out SoC setting.
