6.2 Operation modes
6.2.1 Normal charge mode
When daytime with abundant sunlight, energy storage machine can work in normal charge mode.
● When DC voltage is more than 150V,The energy storage machine detected the inverter has countercurrent
power flow to the grid, The machine would transform the redundant energy exist in PV panel into electric and
store into the battery, the green LED light will be lighten at the moment
● When DC voltage is less than 130V, The energy storage machine will quit the normal charge mode
automatically and turn into standby status, until the PV voltage up to grade again and there is countercurrent
power, the energy storage machine would turn into normal charge mode automatically.
● When DC voltage is more than 150V,while The energy storage machine fail to detect the inverter has
countercurrent power flow to the grid, the energy storage machine won’t start charge, and in the standby
status.
NOTICE: Must connect to AC, or the energy storage machine won’t start up.
6.2.2 Normal discharge mode
When the solar energy is shortage at night, though battery capacity is completely over plus, then the energy
storage machine can work in normal discharge mode.
● When DC input voltage is less than 100V, The energy storage machine detected the inverter has downstream
power flow from grid to load, the energy storage machine will extract energy from the energy storage battery
side, and provide it to inverter as the photovoltaic panel’s mode, meanwhile the inverter transform the DC
current into AC current and feed it to load, the green LED light will be lighten at the moment.
● When DC voltage is less than 100V, The energy storage machine fail to detect the inverter exist downstream
power flow from grid to load, then the energy storage machine will be standby state, and won’t provide any
power.
● When DC voltage is more than 120V,the energy storage machine will transform discharge state to standby
state.
NOTICE: Must connect to AC, or the energy storage machine won’t start up.
6.2.3 Fault mode
The energy storage machine’s intelligent control system could monitoring and adjustment system’s status
continuously, when energy storage machine monitoring anything unexpected happen, such as system fault or
machine fault ,the LCD will display the fault information, in fault mode, the LED light will be lighten.
NOTICE:
a）The detail’s fault information please refer to 9.1
b）Some fault information is in order to remind users that might have some faults occurred in inverter side.
