FAQ

Disconnection Detection
Rapid Shutdown
Replacing an Optimizer
Checking the PV string resistance

Perform disconnection detection on optimizers and locate the disconnected ones.

Method 1: Disconnection Detection on the FusionSolar App  >

Method 2: Disconnection Detection on the WebUI of the FusionSolar SmartPVMS  >

Method 3: Disconnection Detection on the Local Device Commissioning Screen  >
When the output is disconnected or the inverter shuts down, the optimizer can adjust the module output voltage to a safe range to ensure the safety of the construction and O&M personnel as well as firefighters.

Method 1: Turn off the AC switch between the inverter and the power grid.  >

Method 2: Turn off the DC switch on the inverter.  >

Method 3: Connect a switch to the DI and GND ports of the inverter to form a circuit. (For details about which DI port is used, see the corresponding inverter user manual.) The switch is turned on by default. Turn off the switch to trigger a rapid shutdown.  >

Checking the PV string resistance

Checking the PV string resistance Click to view >

The measured PV string resistance must meet the following requirement: PV string resistance (R1 + R2)/2 kΩ ≈ N x 1 kΩ. For example, if there are 16 optimizers in a PV string, the PV string resistance should be about 16 kΩ. If the measured PV string resistance is abnormal, rectify the fault by referring to this section. Click to view >
