Max Charge Voltage is the absolute maximum voltage produced by the charging section of
the inverter in any charge stage.
Hi Battery Alert
initiates an alarm when the battery voltage exceeds this level.
When either “Generic AC Coupling” or “String Inverter” has been set (in System tab. See
page 24) this setting has an additional protection function. When the Hi Battery Alert voltage
has been exceeded for a few seconds indicating a fault in the AC coupled installation, the
SP PRO will ramp the frequency of its AC output to 55Hz to disconnect all connected AC
coupled grid inverters thereby removing all AC coupled charging sources.
When the battery voltage falls to the value set in
Hi Battery Alert Clear the alarm stops.
AC Coupled Trip is the battery voltage at which the SP PRO will trip any Managed AC
coupled Solar to zero output. This is a legacy setting and is not used in firmware versions
greater than 9.09. This is replace by the
Over Target Charge Voltage Trip
setting.
Over Target Charge Voltage Trip is the percentage over the battery charge target voltage
at which the SP PRO will trip any Managed AC coupled Solar to zero output. This setting
is used for Lithium battery or similar technologies that have an absolute maximum battery
charge voltage.
Over Target Charge Current Trip is the percentage over the battery charge target current
at which the SP PRO will trip any Managed AC coupled Solar to zero output. This setting
is used for Lithium battery or similar technologies that have an absolute maximum battery
charge current.
Trip Delay. When the charge voltage or the charge current exceeds the Over Target Charge
Voltage Trip or Over Target Charge Current Trip respectively for this time, then any
Managed AC coupled Solar will trip to zero output. These setting are used for Lithium battery
or similar technologies that have an absolute maximum battery charge voltage or current.
Float Voltage Adjust Only functional when a BMS is used. Some lithium batteries need to
have the charge target voltage reduce slightly when the battery reaches full charge. This is to
prevent over charging the battery bank and tripping the BMS shutdown.
Current Target Scale Only functional when a BMS is used. Scales the BMS target charge
current to account for any calibration errors in the battery BMS. Particularly useful when the
shutdown function in the BMS does not tolerate even the slightest over target charge current.
Battery Settings
The Battery Tab contains settings intended to protect and maintain the batteries.
Please note that you must comply with the requirements of the batteries specifications, failure to
do so may void the battery warranty. When in doubt, consult the battery supplier.
