⚡ Function in the Photovoltaic System
The Solar King SLK-3000 converts electrical energy DC from the photovoltaic modules into 230 V AC energy synchronized with the electrical grid. It is therefore a grid-connected inverter, not a hybrid system and not an off-grid inverter. The SLK-3000 model is specifically documented as a PV Grid Inverter and features a single MPPT tracker.
🔌 PV Input and MPPT
The unit label indicates 360 V DC nominal, with an operating range of 100–500 V DC and maximum input current of 15.2 A. The technical documentation for the model indicates an MPPT range of 150–500 V DC, a maximum open-circuit voltage of 500 V DC and a maximum PV power of approximately 3,510 W.
🏭 Construction and Installation
The Solar King SLK-3000 is designed for photovoltaic installations with grid connection, with an IP65 enclosure and natural convection cooling. The documentation also reports an ambient range of approximately −25/+55 °C for the family; the nameplate of the photographed unit indicates −20…+55 °C, which should be considered the priority data for this specific product.
⚠️ Main Faults
The faults documented for the SLK-3000 include:
-
DC Overvoltage: PV voltage above the 500 V limit.
-
High/Low DC Bus: internal DC bus voltage fault.
-
Grid Relay Fault: problem in the AC coupling circuit.
-
Device Fault: internal inverter fault.
-
Overtemperature: excessive internal temperature.
-
No Grid Voltage: absence or fault of the AC grid.
🛡️ Safety and Product Condition
New product, as indicated for the listing. The inverter operates with voltages up to 500 V DC and 230 V AC; connection and commissioning must be carried out by qualified personnel. Before working on the device, it is necessary to verify the absence of voltage on both the PV side and the grid side.
