  • Page 18: Features

    The Conext XW+ is a self-contained DC to AC inverter, battery charger, and integrated AC transfer switch. It is configurable in a hybrid system to operate with generators and renewable energy sources.

  • Page 19: Available Conext Xw+ Accessories

    Operation Bidirectional Theory of Operation The Conext XW+ is a grid forming device consisting of a bidirectional inverter/ charger. It is capable of inverting DC power into AC power and controlling the voltage and frequency of its inverter output. It will power external loads attached to AC OUT (See Figure 1-2, “Inverting of DC to AC Connected to AC OUT”...
  • Page 20 K2, Conext XW+ can facilitate advanced interaction with the utility grid to optimize the utilization of renewable and non-renewable energy sources. Because the Conext XW+ is a device capable of forming an AC grid signal (AC voltage and frequency) it is also ideal for use off-grid.

  • Page 23: Surge Performance

    With permission from the utility, the factory settings may be changed to allow the Conext XW+ to operate over a wider grid voltage range. These settings must only be changed by qualified service personnel using a special software application (Conext Configuration Tool, Order # 865-1155-01) provided by the manufacturer.

  • Page 24: Ac Coupling

    To enable the PV inverter to provide power during a grid outage the Conext XW+ is retrofitted in front of the PV inverter. The PV inverter is rewired from the grid connection to a critical load (sub) panel and the AC Couple is on the Conext XW+ AC Output port.

  • Page 25: Multi-Unit Operation

    Three Conext XW+ units can also be configured in a cluster for three-phase operation using a single PDP (PDP is optional). Up to three clusters of three Conext XW+ units can be installed in a three-phase configuration when using an external AC contactor.

  • Page 26: Auxiliary Output

    Introduction AC Transfer Multiple Conext XW+ units monitor each other to determine the quality of AC input. If AC input is deemed to be bad by any of the paralleled units, no transfer to AC Out occurs and the AC LED continues to flash on each unit’s information panel until the AC is qualified by all.

  • Page 27: Monitoring The Conext Xw

    Operation of the Conext XW+ can be monitored using the factory-installed inverter information panel or the optional Conext System Control Panel and ComBox.

  • Page 30: Monitoring Operation With The Inverter Information Panel

    Monitoring Operation Monitoring Operation with the Inverter Information Panel The inverter information panel on each Conext XW+ monitors a single Conext XW+. The Conext XW+ information panel displays basic information and performs start up, shut down, equalization and standby functions. LEDs on the information panel indicate AC input status, Conext XW+ status, battery condition, and charging and equalization status.

    This cycle is used to restore battery capacity when battery life has deteriorated due to sulphation. After the button is pressed the Conext XW+ begins a full charge cycle, which is automatically followed by an equalization cycle.
  • Page 34 Note: In a system where more than one device is capable of equalizing batteries (such as a system including multiple Conext XW+ units and/or Conext 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.

  • Page 35: Using Startup/Shutdown/Standby Modes

    Conext Solar Charge Controllers continue to operate if Xanbus network power is removed, but they do not continue to communicate with each other. Furthermore, the Conext Combox will not collect harvest data while it is off, even though MPPT is still functioning and collecting data.

    If the battery voltage exceeds this limit for more than 1 minute, the Conext XW+ displays a fault message (F49) and shuts down. The inverter will not support AC loads when in this condition. If a qualified AC source is present, the unit passes AC through to the loads.

    Otherwise – in both of the scenarios above – inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the Conext AGS from starting the generator or result in the Conext XW+ cycling on and off multiple times before the generator automatically starts.

    Inverter Applications Inverter Applications The Conext XW+ performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section. Resistive Loads Resistive loads are the easiest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another.

  • Page 129: Conext Xw+ Overload Capability

    Conext XW+ Overload Capability Loads connected to the inverter are seldom constant, and large loads are often operated for short periods. To accommodate larger loads, the Conext XW+ can temporarily exceed its continuous output power rating. The graphs below illustrate approximate operation time versus load. Inverter operation time during overload is limited by both inverter internal temperature protection and by the product of AC output current and elapsed time.
