Installation and Operating Manual
1. Introduction 1.1 General Thank you for choosing Darfon PVI5000 inverters as your power conversion devices in the solar power system. This document contains important information for the installation and settings of this product. Therefore, before you start the installation and settings, it is highly recommended to read this manual carefully. The use of string PV concept significantly reduces the cabling costs on a photovoltaic system.
other conditions necessary for grid connection are checked and fulfilled for a certain period of time, the PVI5000 inverter goes into the Grid with MPPT mode that turns the AC relays on and begins feeding the AC voltage into the grid steadily. When all of the input DC voltages fall below the initial voltage setting which is 100Vdc, the PVI5000 inverter will then shut itself down.

2.Safety 2.1 Safety Notification The PVI5000 inverters may contain high voltages and the risk of electrical shock, even when no external voltage is present. Only the trained qualified electrical personnel are allowed to perform the electrical installation, wiring, opening, repair, and modification of the PVI5000 inverters. The temperature of the heat sinks outside of the device can reach over 70°C in normal operation. There is risk of burn injury when these parts are touched.
2.2 Safety Symbols To reduce the risk of injury and to ensure the continued safe operation of this product, the following safety instructions and warnings are marked in this manual. Warning, risk of electric shock The lighting flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of dangerous voltage with in the product’s enclosure that may be constitute a risk of injury or death to users and / or installers.
2.3 Wiring the Inverter The following three sections describe the connections of wirings for the DC, AC, and communication ports. The PVI5000 has two (2) pairs of DC connection terminals, string A and B. The DC connection terminals are used to connect to PV strings through circuit breakers. Each pair of the DC connection terminals shall be connected to one PV string with the maximum rating value of voltage and current.
2.3.1 DC Cable Connection The PVI5000 is designed to support two independent PV strings, string A and B. Each PV string shall provide a DC input voltage with maximum power of 3000 W and maximum current of 12 A. The are two (2) terminals, labeled as “+” and “-”, DC voltage input located on the bottom of the inverter used for the DC cable connections. Fig. 3.3.2.1 DC terminals for DC cable connection Connect the Positive (+) wire from the #1 PV string to the PV1 (+) terminal.
! CAUTION! The DC voltage must be less than 550 V in any condition. WARNING! Route the DC connection cables to the PVI5000 inverters away from any possible hazards that could damage the cables. WARNING! Allow at least 5 minutes for PVI5000 inverter to discharge energy completely, since the hazardous voltage will remand on the device after disconnecting all PV DC input. 2.3.
2.4 Operation Feature (1)Independent / parallel mode automatic detection: PVI5000 can provide two inputs in connection with PV arrays, and it can detect automatically the connection type of PV arrays; that is parallel or independent mode. Through this convenient method, we give more flexible connections of PV arrays for system installers. It lets the system installers match the PV arrays with more appropriate and optimum solutions and get more power efficiency.
