Note: For PV inverters and grid code settings that only allow partial curtailment, there is a
possibility of PV inverter cycling at the end of the absorption charge cycle. If this occurs, the
Conext XW+/SW Absorb Time limit can be reduced to trigger an earlier transition to Float,
where the PV inverters will remain disconnected until the batteries need to be re-charged
(triggered by the ReCharge Volts parameter).
NOTICE
RISK OF EQUIPMENT DAMAGE
For PV inverters and grid code settings that only allow partial curtailment, reduce the Conext
XW+/SW Absorb Time limit.
Failure to follow these instructions can result in battery damage.
When setting the frequency, use the same start frequency as the PV inverter (i.e. 50.2 or
60.2 Hz). Then set the maximum frequency 0.1 Hz lower than the frequency corresponding
to zero power production on the PV inverter. In this example, the setting would be 51.2 or
61.2 Hz.
To access off-grid mode, see the respective product manuals for the PV Inverters. Example
inverter PV settings:
n Set the frequency for start of power reduction. We recommend using VDEAR-N 4105
default for start (50.2 Hz), but any other setting can be used. For 60 Hz systems, use
60.2 Hz.
n Set the frequency when PV inverter power output will be zero. We suggest at least 1 Hz
higher, 51.2 (or 61.2) Hz.
n Set the high frequency disconnect on the PV inverter about 0.3 Hz higher or 51.5 (or
61.5) Hz.
