Operating Instructions for Installers and Operators

General Notes About this documentation WARNING Improper handling of the inverter can be hazardous › You must read and understand the operating instructions before you can install and use the inverter safely. Other applicable documents During installation, observe all assembly and installation instructions for components and other parts of the system. These instructions are delivered together with the respective components and other parts of the system. Some of the documents which are required for the registration and approval of your photovoltaic (PV) system are included with the operating instructions....

Safety DANGER Lethal voltages are still present in the terminals and cables of the inverter even after the inverter has been switched off and disconnected. Severe injuries or death if the cables and/or terminals in the inverter are touched. Only authorised electricians who are approved by the supply grid operator may open, install or maintain the inverter. › Keep the inverter closed when the unit is in operation. › Do not touch the cables and/or terminals when switching the unit on and off. › Do not make any modifications to the inverter. The electrician is responsible for observing all existing...

Protection features For your safety, the following monitoring and protective functions are integrated into Powador inverters: • Overvoltage conductors/varistors to protect the power semiconductors from high-energy transients on the grid and generator side • Temperature monitoring of the heat sink • EMC filters to protect the inverter from high-frequency grid interference • Grid-side grounded varistors to protect the inverter against burst and surge pulses • Islanding detection according to VDE 0126-1-1 Additional information NOTE The EU declaration of conformity can be found in the appendix....

The inverter converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid. The feed-in process begins when there is sufficient sunlight and a specific minimum voltage is present in the inverter. If, as it gets dark, the voltage drops below the minimum voltage value, the feed-in operation ends and the inverter switches off.

PV generator The PV generator, i.e. the PV modules, converts the radiant energy of sunlight into electrical energy. DC terminal point Options for parallel connections of several generator strings: • To a DC terminal point between the DC generator and inverter, • Directly to the inverter (plug connectors for 4 (2 x 2) strings are provided on the inverter) • Directly to the PV generator with a positive and negative lead to the inverter DC disconnect Use the DC disconnect to disconnect the inverter from all power sources on the PV generator side. Grid fuses gL safety fuses or automatic circuit breakers...

Electrical functions Fault signal relay A potential-free relay contact is integrated in the inverter. The contact closes as soon as there is a fault during operation. Country-specific function 3.2.3.2 Fault signal relay/Powador-priwatt A potential-free relay contact is integrated in the inverter. Use this contact for one of the following functions: • Fault signal relay (see above) • Powador-priwatt Powador-priwatt Paragraph 33 of the German Renewable Energies Act (EEG) includes compensation for personal consumption of self-generated PV energy for systems up to a maximum of 500 kWp. The energy...

Mechanical components DC disconnect The DC disconnect is located on the bottom side of the inverter housing. The DC disconnect is used to disconnect the inverter from the PV generator in order to carry out service. Disconnecting the inverter from the PV generator Switch the DC disconnects from 1 (ON) to 0 (OFF). Connecting the inverter to the PV generator Switch the DC disconnects from 0 (OFF) to 1 (ON). The inverter has the following interfaces for communication and remote monitoring: • RS485 interface • Ethernet interface • USB interface • S0 interface You configure the interfaces and the web...
