  • Page 3: Introduction

    1. Introduction 1-1. Overview The EnerSolar 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 allowed for 2 arrays of PV modules. Embedded with two smart independent MPPTs, the EnerSolar PV inverter can operate at optimum power output voltage.

  • 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.
