Problems solved by technology
Standard shape high power inverters are heavy
The 500KW inverter weighs more than 2000kg, and the 100KW inverter weighs more than 900kg. For remote areas, especially in mountainous areas, it is very difficult to transport the inverter to the installation location
For example, a triplet 500KW inverter, this one-piece chassis is the standard structural form of high-power inverters, the three parts of the chassis are connected as a whole, transported and installed as a whole, the weight is 2100kg, and it is very difficult to move without transportation. difficulty

The invention discloses a split disassembly photovoltaic inverter. The split disassembly photovoltaic inverter comprises a chassis, and also comprises a split transformer which can be assembled with the chassis; a tray for moving the split transformer is arranged on the lower part of the split transformer; the chassis is provided with at least one installing door used for the entrance and the exit of the split transformer and a transformer installing beam used for fixing the split transformer; the chassis comprises a chassis pedestal back beam for closing the installing door; the split transformer is assembled and matched with the tray in a disassembly way; the transformer installing beam is assembled and fixed to the split transformer through transformer fixing bolts, and is also assembled and fixed to the chassis through installing beam fixing bolts; and the chassis pedestal back beam is assembled and fixed to the chassis through chassis pedestal back beam fixing bolts. The invention aims to split the inverter which is very heavy originally, so that the inverter is convenient to transport. Compared with the conventional general inverter, the photovoltaic inverter provided by the invention used in remote regions is more convenient to transport, and the efficiency also can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of photovoltaic inverters, in particular to a split and detachable photovoltaic inverter and an installation method thereof. Background technique [0002] Inverters, also known as power regulators, can be divided into two types: independent power supply and grid-connected use according to the use of inverters in photovoltaic power generation systems. According to the waveform modulation method, it can be divided into square wave inverter, ladder wave inverter, sine wave inverter and combined three-phase inverter. For inverters used in grid-connected systems, they can be divided into transformer-type inverters and non-transformer-type inverters according to the presence or absence of transformers. During my country's "Eleventh Five-Year Plan" period, photovoltaic power generation supporting equipment such as inverters are mostly in the research and development and innovation stages, and have received less po...
