  • Page 3: Introduction

    1. Introduction 1-1. Overview This PV inverter is designed to convert solar electric (photovoltaic or PV) power into utility-grade electricity that can be sold to the local power company. This inverter is embedded with smart MPP tracker to allow the PV inverter to operate at optimum power output voltage. PV module 1 PV module 2 (only for 5KW)

  • Page 4: Important Safety Warning

    Important: The inverter will reduce its output generation to protect its electronic circuits from overheating and any damage under high temperature environment. For maximum power output in high temperature, it’s recommended to mount the inverter in a shaded location with good ventilation.
  • Page 5 WARNING! Before installing and using this inverter, read all instructions and cautionary markings on the inverter and all appropriate sections of this guide. WARNING! Normally grounded conductors may be ungrounded and energized when a ground fault is indicated. WARNING! This inverter is heavy. It should be lifted by at least two persons. CAUTION! Authorized service personnel should reduce the risk of electrical shock by disconnecting both the AC and DC power from the inverter before attempting any maintenance or cleaning or working on any circuits connected to the inverter.

    5. Grid (AC) Connection 5-1. Preparation Before connecting to AC utility, please install a separate AC circuit breaker between inverter and AC utility. This will ensure the inverter can be securely disconnected under load. NOTE1: Although this inverter is equipped with a fuse (F1 point on PCB, 3KW: 250VAC/20A; 5KW: 250VAC/30A), it’s still necessary to install a separate circuit breaker for safety consideration.

    6. PV Module (DC) Connection CAUTION: Do NOT connect battery or DC source to PV connectors. Otherwise, it will cause inverter damage. CAUTION: Before connecting to PV modules, please install separately a 2P circuit breaker for 3KW, 4P or two 2P DC circuit breakers for 5KW between inverter and PV modules. NOTE: Please use 600VDC/15A circuit breaker for 3KW and 600VDC/17A circuit breaker for 5KW.
  • Page 13 Positive terminal connection Step 2: Check the input voltage of PV array modules. The acceptable input voltage of solar inverter is 125VDC - 500VDC. If this system is only applied with one string of PV array, then please make sure that the maximum current load of each PV input connector is 13A for 3KW and 15A for 5KW.
  • Page 14 WARNING! It's very important for system safety and efficient operation to use appropriate cable for DC connection. To reduce risk of injury, please use the proper recommended cable size as below. Suggested cable requirement for DC wire Model External Conductor cross-section AWG no.
