4 FAQs about Huawei PV Inverter Startup Procedure

Why is Huawei fusionsolar smart PV management system not working?

Huawei FusionSolar Smart PV Management System shows that the communication with the inverter is interrupted. The RS485 cables among inverters are loose or disconnected. The PV string is not properly connected, and the inverter has no DC input. The baud rate or RS485 address of the inverter is changed. The Smart Dongle is faulty.

How do I start my sun2000 inverter?

The inverter can start normally after the fault is automatically cleared. Step 2 Set DC SWITCH 1 (MAIN SWITCH) at the bottom of the SUN2000 chassis to ON. When you hear a click sound, the switch is ON. Page 75 SUN2000- (196KTL-H0, 200KTL-H2, 215KTL-H0) User Manual 6 System Commissioning Step 3 Check the status of LED 1.

Why is my smart dongle not connected to Huawei fusionsolar smart PV management system?

The devices connected to the Smart Dongle are not connected to the Huawei FusionSolar Smart PV Management System properly. Check whether the inverter software version meets the requirements. If not, upgrade the inverter to a specified version or later. Check that the RS485 communications cables are connected properly.

How do I Fix my sun2000 power grid failure?

Turn on the AC switch between the SUN2000 and the power grid. If the DC is on and the AC is off, the SUN2000 reports a Grid Failure alarm. The SUN2000 starts normally only after the fault is automatically rectified. (Optional) Remove the locking screw from the DC switch. Turn on the DC switch (if any) between the PV string and the SUN2000.

Powering On the Inverter

Off The inverter is disconnected from all PV strings, or the DC input voltage of all MPPT circuits is less than the minimum startup voltage. Steady red If the alarm/maintenance indicator is red, an internal fault on the DC
