Conext XW PRO 6848 6,800W 48V Installation

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.
When the Time in Float is different than zero, PLS shall start only if the battery amperage
remained at the specified level for the configured time.
Example Settings
Load Shave=Enabled, LoadShaveAmps=10 A,
LoadShaveStart=6:00pm, LoadShaveStop=9:00pm, Time in Float=60
min, Peak Load Shave Delay = Enabled.
With these example settings, the Conext XW Pro would enter PLS within the configured
window of time only if the battery was charged from MPPT in Float (including Absorption)
for 2 hours.
NOTE: When actively operating, the Conext XW Pro compensates for active power as a
reference for controlling the total current as specified in the Load Shave Amps setting.
However, there is also reactive power that is not compensated for by the Conext XW
Pro. For example, if Load Shave Amps is set to 10A, the inverter will only start
drawing power from the batteries at a current level which would measure approximately
11A which is 1A higher than the Load Shave Amps value to meet the demand of the
loads.
Time-of-Use Metering
Utilities use time-of-use metering to determine utility charges during peak usage hours
and to impose a surcharge. The Conext XW Pro can be configured (using the Load
Shave Start, Load Shave Stop and Charger Block settings) to overcome
these peak charges by using utility power to charge the battery bank during the
inexpensive energy hours and consuming the battery energy during expensive energy
hours.
For example, if Charger Block is set between 9:00 AM and 10:00 PM and Load
Shave is set between 6:00 PM and 9:00 PM, charging on AC1 stops at 9:00 AM and
continues to pass through utility AC to the loads. If charging is required during the charger
block period, and AC Priority is set to AC2, the Conext XW Pro can use any AC
source connected to AC2. Loads will transfer to the AC source on AC2 as well.The
inverter connects to the utility grid at 6:00 PM and supports loads using the batteries. The
inverter continues to run until 9:00 PM. The Conext XW Pro then stops supporting the
utility grid and passes utility AC through to the loads. At 10:00 PM utility AC begins
maintaining the batteries based on the battery charger settings.
The above example allows an external renewable energy source to be utilized as a
primary charging source during a desired time window. The charger (usingutility AC
connected to AC1) can then be used to supplement the battery charging when the utility
rates are low.
