R3 Note Series User manual 1. Introduction 1.1 Introduction This manual describes solar inverters: R3-4K / R3-5K / R3-6K / R3-8K / R3-10K-A / R3-10K / R3-12K. 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 connecting it to the utility AC grid.
The inverter incorporates an input power limiting device, which automatically keeps the power at levels that are safe for the inverter. 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.
