📝 Description
Used product. Original Fronius Power Rack 3000 power module, Part No. 43,0001,1228, intended for modular photovoltaic inverters of the Fronius IG series. The component is an internal inverter power module, so it must not be considered a complete standalone inverter.
The Power Rack 3000 constitutes an approximately 3 kW DC/AC conversion stage and is installed in the internal power system of the inverter. Fronius spare-parts documentation identifies code 43,0001,1228 within the IG 300 / IG 390 / IG 400 / IG 500 family.
⚙️ Technical Specifications
-

⚡ Function in the Electrical System
The Power Rack 3000 is a fundamental modular element of high-power Fronius IG inverters. Multiple modules can be installed inside the same inverter to achieve the required overall power; a module failure can therefore cause reduced available power or specific inverter warnings. Fronius documentation identifies the component as Power Rack 3000 for the IG 300/390/400/500 platform.
Faults associated with the Power Rack system may include generic messages relating to one or more power modules, such as STATE 516, which indicates that the daily limit for error messages from a Power Rack has been exceeded.
🏭 Construction and Installation
The component features an industrial construction with a metal housing, finned heat sinks, transformers, inductors, capacitors, and internal wiring. A green “Status” LED is present on the front.
Documented compatibility: Fronius IG 300, IG 390, IG 400 and IG 500; before installation, it is nevertheless advisable to verify the spare-part code and inverter revision.
🛡️ Safety and Product Condition
The component is used and shows normal signs of previous installation and use. The photographs show the metal housing, heat sinks, and main components to be intact; however, the electrical operation of the module cannot be certified based solely on visual inspection.
As a power module for a photovoltaic inverter, it may be subject to dangerous DC and AC voltages and the presence of capacitors that may retain residual charge. Installation, diagnosis, and replacement must be carried out exclusively by qualified personnel.
🚀 Final Description
Original Fronius Power Rack 3000, Part No. 43,0001,1228, approximately 3 kW power module for Fronius IG 300 / IG 390 / IG 400 / IG 500 modular photovoltaic inverters. It is a useful spare part for repair, maintenance, and replacement of power modules on discontinued Fronius IG inverters. The component is supplied as a single Power Rack, not as a complete inverter.
