CHARGER CONTROL restricts the total AC power level and all the AC Sources (if any) from which the
battery is being charged. The settings under Charger Control are active until the Battery SoC drops to the Start
SoC setting under Charger Override, at which point the settings under Charger Override become active. The
Charger Override settings will remain active until the battery SoC reaches the Stop SoC setting.
The settings below apply to both the Charger Control and the Charger Override.
Battery Charging
sets the charging source. The three options are:-
Charging On:
The SP PRO will comply with the requirements of the “Charger” Settings unless they exceed
the Restricted Charge Limit setting. If the rating of the inverter is less than the Restricted Charge Limit
setting then the inverter’s rated charge power will apply. This will reduce as temperature of SP PRO increases.
The Grid Input Limit setting can also affect the charge power as this cannot be exceeded when charging from
the grid.
In summary the max charge power is the lesser of the following:
• The Charger settings limit.
• The Restricted Charge Limit setting
• The inverter Charge power rating (temperature dependent).
• Available power from all charging sources (Grid Input Limit –Load power + renewable
Power).
The Charge Limit is displayed in the Data View > Now tab and is the lesser of:
• The Restricted Charge Limit setting
• The inverter Charge power rating (temperature dependent).
Renewable Only:
The SP PRO maximum charge power will be the lesser of the following
limits.
• The Renewable Power available for charging = Renewable – Load power
• The Charger settings limit.
• The Restricted Charge Limit setting
• The inverter Charge power rating (temperature dependent).
The Charge Limit is displayed in the Data View > Now tab and is the lesser of:
• The Renewable Power available for charging = Renewable – Load power
• The Restricted Charge Limit setting
• The inverter Charge power rating (temperature dependent).
It should be noted that Charging On setting with a Grid Input limit of 0kW
operates the same as Renewable Only. This is because nothing can come from
the grid during charging so charging can only come from renewable sources.
Charging Off:
Battery recharging disabled. This option will be overridden by any DC
coupled solar charging sources when the AC Source (Grid) is disconnected or the Inverter is
disconnected. It will be overridden by any Generic AC coupled sources when the AC Source
(Grid) is disconnected.
CHARGER OVERRIDE settings become active instead of the Charger Control settings
when the Battery SoC transitions down though the Start SoC setting. They revert back to
the Charger Control settings when the Battery SoC transitions up through the Stop SoC
setting. Override Charge Limit settings have the same function as the Restricted Charge
Limit settings.
AC Source limit during Override allows an alternative AC Source limit to be used when the
battery Charging is in Charger Override.
Selecting Grid Input Limit (default value) means there will be no change to the AC Source
Limit during Charger Override.
Selecting AC Source Power means that the AC Source Limit will change to the AC Source
Power setting in the Quick Start section under the Configurations Settings tab.
POWER OVERRIDE only operates when the Allow Power Override is enabled in the Installer Only
Service settings. When set, the
SP PRO exports a constant power from the battery bank into its
AC output port. (feeds the AC loads then exports any excess to the grid).
