5. Installation and Operating Manual 1 Introduction 1 1 General Thank you for choosing Darfon PVI4000 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 The use of just two parallel strings of PV modules in series has proven advantageous by delivering a high operating voltage to the solar inverter This advantage is primarily reflected in a higher efficiency of the inverter Careful optimization of the overall inverter system s cost and efficiency lead to the choice of a 550V DC maximum system voltage for the PVI4000 for use with 1 kW to 5 3 kWPV arrays per inverter The PVI4000 inverter is designed to cover solar electric power into utility grade electricity that can be used by home or local power company PVI4000 inverter is designed to support two 2 PV strings and operate automatically without any configuration once it is installed and commissioned according to the technical specifications When at least one of the DC input voltages generated by the photovoltaic module goes above the initial voltage setting and under the pre set threshold value the embedded controller is then waked up and goes through the
6. checking mode and then stay at CNTing mode because the pre set threshold value is not reached yet At this time the PVI4000 inverter would not feed the AC power to the mains utility instead it keeps watching the input DC voltage Once the input DC voltage goes up above the pre set threshold value and all other conditions necessary for grid connection are checked and fulfilled for a certain period of time the PVI4000 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 PVI4000 inverter will then shut itself down The PVI4000 inverter will be waked up automatically when one or more of the input DC voltages go up above the initial voltage setting Maximum power point tracking The PVI4000 inverter use Darfon proprietary maximum power point MPPT tracking technology to get the maximum amount of energy form the solar array which helps your arrays to have maximum output at all times 1 2 Specification Table Model Name PVI 4000 AC Nominal Voltage Range AC Grid Frequency Nominal Output Power Maximum Output Power Maximum Output Current Waveform Power Factor H Phase Maximum DC Power Maximum Input Voltage MPP Voltage Range Peak Power Tracking Voltage Maximum DC Input Current Number of MPP Tracker Euro Efficiency Consumption Operating standby Night lt 20W
