Page 15: Operation Modes
6.2 Operation modes EA33/40KTLSI supports unattended monitoring, automatic operation and judges if grid-connection power generation is required according to the output power of PV arrays. The system operation process includes five work status: startup, grid-connected operation, standby, sleep, shutdown and troubleshooting. Figure 6 presents the operation mode conversion process for EA33/40KTLSI grid-connected inverter (Vpv means the DC output voltage of PV array) Vpv <... -
Page 16: Monitoring Mode
When the output power of PV arrays is low and less than 100W in consecutive 5 minutes, and no demand for SVG scheduling in night, the system will access to shutdown mode. When the system detects a failure, it will separate the inverter from the power grid under any circumstances. In this state, LED fault indicator flashes giving alarm prompt. -
