1. SONAR can work as traditional off grid inverter or as a hybrid inverter. When disable PV&AC
Take load Jointly, it will work as a traditional off grid inverter, otherwise it will work as a hybrid
2. Working as a traditional off grid inverter. In this situation, inverter either use (solar+battery) to take load
or use AC take load. Related settings
AC First: During the setting time, system will use AC to take load first, use solar power to charge the battery.
If the battery is full, solar power may be wasted. When out of the setting time, system will use battery and
solar to take load until battery voltage/SOC is lower than cut off voltage/SOC
3. Working as a hybrid inverter
Related settings
3.1 AC First: During this setting time, system will use AC to take load, use solar power to charge the battery
first. If there is extra solar power, extra solar power will take the load. When out of the setting time, system
will use solar and battery to take load first until the battery voltage/SOC is lower than On Grid EOD settings,
then it will use AC to take the load.
3.2 Export to Grid/Export Power percent: Users can also enable export function, it is allowed and set export
power percent
3.3 AC Charge function Disable: The system will not use AC to charge the battery(except Li ion BMS set
force charge flag )
According to Time: During the setting time, system will use AC to charge the battery until battery full and
battery will not discharge during the setting time.
According to Battery Voltage: During the setting time, system will use AC to charge the battery if battery
voltage is lower than AC Charge Start Battery Voltage and will stop when Voltage is higher than AC Charge
End Battery Voltage. And battery will not discharge during the setting time.
According to Battery SOC: During the setting time, system will use AC to charge the battery if battery SOC
is lower than AC Charge Start Battery SOC and will stop when Voltage is higher than AC Charge End Battery
SOC. And battery will not discharge during the setting time.
