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. 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 PVI5000 for use with 1 kW to 5.3 kWPV arrays per

inverter.

The PVI5000 inverter is designed to cover solar electric power into

utility grade electricity that can be used by home or local power

company.

PVI5000 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 checking mode and then stay at CNTing mode

because the pre-set threshold value is not reached yet. At this time,

the PVI5000 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
