1.2 Applied designations
1. Introduction
This manual describes solar inverters ：
R3-30K / R3-36K / R3-40K / R3-50K.
These inverters are transformerless based inverter.
1.3 Importantsafety information
1.4 System sizing
1.1 Introduction
Before installation:
Installation:
Disconnecting the inverter:
Operating the inverter:
should be used.
Functional safety parameters:
When dimensioning a photovoltaic system, it must be ensured that the open
circuit voltage of the PV string never exceeds the maximum permissible
input voltage of 1100V DC. The PV string open circuit voltage during parallel
string operation is 1000V. Higher voltages may result in permanent damage
to the inverter.
