⚡ Function in the Photovoltaic System

The Solar King SLK-6000 converts direct current from the photovoltaic panels into single-phase 230 V AC, synchronized with the electrical grid. It is therefore a grid-connected inverter, not designed for standalone off-grid operation or direct battery management. The manufacturer's documentation identifies it as a grid PV inverter.

☀️ PV Input and MPPT

The inverter features 1 MPPT tracker with a range of 150–600 V DC. The nominal PV generator voltage is 360 V DC, while the operating range indicated on the nameplate is 100–600 V DC, with 600 V DC as the maximum permitted voltage. The maximum input current is 30 A. The series documentation also indicates up to 6.5 kW maximum PV input power for the SLK-6000 model.

🔌 AC Output and Grid Connection

The output is single-phase 230 V AC, with a frequency of 50/60 Hz and a nominal/maximum current of approximately 26.1 A. The system integrates grid control and protection functions during connection to the public grid. The Solar King series also provides monitoring possibilities through a serial interface, with remote communication options depending on the configuration.

⚠️ Main Faults and Diagnostics

The main fault conditions that may affect this inverter family include DC overvoltage, insufficient or abnormal DC-Link voltage, absence/fault of the AC grid, overtemperature, internal power electronics faults, and faults in the earth leakage detection system. Protection against overcurrent and abnormal PV field conditions is also provided.

🏭 Construction and Installation

The Solar King SLK-6000 features an IP65 enclosure, natural convection cooling, and a structure designed for installation in technical/outdoor environments according to the conditions specified by the manufacturer.

🛡️ Safety and Product Condition

New product. The inverter contains potentially dangerous voltages up to 600 V DC and 230 V AC: connection, inspection, and maintenance must be carried out exclusively by qualified personnel.
