  • Page 3: Introduction

    1.Introduction 1.1 Introduction This manual describes solar inverters: NAC4K-DS/NAC5K-DS/NAC6K-DS/NAC7K-DS/NAC8K-DS. These inverters are transformerless based inverter. Please read the safety instructions in this manual first. Throughout the manual it is assumed that the reader is familiar with AC and DC installations and knows the rules and regulations for electrical equipment and for connecting it to the utility AC grid.

  • Page 4: Important Safety Information

    The limitation depends mainly on internal and ambient temperatures. The limitation is calculated continuously and always allows the maximum possible amount of energy to be produced. Please use the tool supplied by Renac Power when dimensioning a photovoltaic system.

    3. Installation and startup Warning！ Before installation and maintenance, AC and DC side doesn’t carry electricity, but if DC side is just disconnected, capacitance still contains electricity, so please wait for at least 5 minutes to ensure the capacitors completely release the energy and inverter is not electrified.

  • Page 10: Installation Position

    Please do not install inverter under direct sunlight, rain and snow. Figure 3-2 installation environment 3.3 Installation position The installation method and mounting location must be suitable for the inverter's weight and dimensions. Mount on a solid surface. Select a well-ventilated place sheltered from direct sun radiation. Figure 3-3 installation position In consideration of heat dissipation and convenient dismantlement, the minimum clearances around the inverter should be no less than the following value:...
