by the PV modules into AC power and supplies them to the grid.
When the DC voltage is lower than 180Vdc, inverter will enter into "waiting" state
and try to connect to the grid, at this status, inverter consume very small power to
check the internal system status.
Note: only when the PV modules supply enough power(voltage＞195Vdc) then the
inverter will start automatically.
7.2.3 Fault mode
Inverter intelligent control system will continuously monitor and adjust system
status. When there is a fault detected, LED will show the fault message.
Note: Please refer to section 8.2 to check the fault message and take corrective
measures.
7.2.4 Off mode
When the sunlight is weak or no light, inverter will stop working automatically. When
it is off, inverter will not consume gird power or PV module. At the same time, the LED
of inverter will be turned off.
Note: When PV string DC voltage is too low(≤ 150Vdc), inverter will be off.
7.3 LED Display
Inverter current operation status can be visually checked from LED display directly.
