6 FAQs about [Photovoltaic inverter dry contact function]
What is a PV inverter?
Product Description System Introduction The inverter is a transformerless 3-phase PV grid-connected inverter. As an integral compo- nent in the PV power system, the inverter is designed to convert the direct current power generated from the PV modules into grid-compatible AC current and to feed the AC current into the utility grid.
What is included in a photovoltaic system manual?
About This Manual The manual mainly contains the product information, as well as guidelines for installation, operation and maintenance. The manual does not include complete information about the photovoltaic (PV) system.
How to remote shutdown over dry contacts?
Log in as Special User and set parameters for remote shutdown over dry contacts. Set this parameter to the DI port connected to OVGR signals. The value can be Open or Close.
How do I shut down a solar inverter over ovgr signals?
The SmartLogger shuts down the solar inverter over OVGR signals. When setting this function, ensure that the user-defined DI port is not occupied. Otherwise, the setting will fail. Log in as Special User and set parameters for remote shutdown over dry contacts. Set this parameter to the DI port connected to OVGR signals.
What is effective dry contact status?
Effective dry contact status can be set to Close or Open. If OVGR Shutdown Setting is set to Enable and Effective dry contact status is set to Close, the SmartLogger sends the inverter remote shutdown command only when the DI port specified by connection port is closed. OVGR Shutdown Setting can be set to Enable or Disable.
What happens if a solar inverter is configured with optimizers?
When all PV modules connected to the solar inverter are configured with optimizers, the PV system shuts down quickly and reduces the output voltage of the PV string to below 30 V within 30 seconds. If optimizers are configured for some PV modules, the rapid shutdown function is not supported. Perform the following step to trigger rapid shutdown:
