Problems solved by technology

[0006] (2). The traditional 3.125MW outdoor unit (relatively large in size) is used. Although this method can reduce the manufacturing cost of the whole unit, it does not consider the size limit of the 3.125MW step-up integrated unit during transportation during the design, resulting in transportation costs will increase;

Embodiment Construction

[0028] The invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0029] like figure 1 As shown, the present invention proposes a high-power outdoor photovoltaic inverter with high power density, compact structure and reasonable layout. The high-power outdoor photovoltaic inverter includes a cabinet, and two DC cavities 1 arranged in the cabinet , Power chamber 2, AC chamber 3 (including bus capacitance and AC capacitance). The two DC chambers 1 are respectively arranged on the left and right sides of the cabinet, the AC chamber 3 is arranged on the back of the cabinet, the two DC chambers 1 and the AC chamber 3 communicate with each other, and the power chamber 2 is arranged on the cabinet The middle part of the front is completely isolated from the AC chamber 3 and the two DC chambers 1 . There are air inlets 4 around the top of the cabinet, and air outlets at the bottom.

[0030] like figure 2 As shown, the DC cavity ...

Abstract

The invention discloses a high-power outdoor photovoltaic inverter, which comprises a cabinet, two direct-current cavities, a power cavity and an alternating-current cavity, wherein the two direct-current cavities, the power cavity and the alternating-current cavity are arranged in the cabinet, the two direct-current cavities 1 are respectively arranged at the left side and the right side of the cabinet, the alternating-current cavity is arranged at the back of the cabinet, the two direct-current cavities 1 are communicated with the alternating-current cavity 3, the power cavity is arranged inthe middle of the front surface of the cabinet and is completely isolated from the alternating-current cavity and the two direct-current cavities, air inlets are formed in the periphery of the top ofthe cabinet, and air outlets are formed in the bottom of the cabinet. The high-power outdoor photovoltaic inverter is high in power density, compact in structure and reasonable in layout, and the overall dimension of the whole inverter is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic inverters, in particular to a high-power outdoor photovoltaic inverter. Background technique [0002] With the grid parity of photovoltaics, the price of photovoltaic inverters is getting lower and lower, and the market competition is becoming more and more fierce. Due to the combination of traditional containers and indoor inverters, the price of the whole machine remains high, so each inverter Inverter manufacturers have turned the design of inverters to outdoor inverters. Outdoor inverters are becoming more and more popular among inverter manufacturers because of their relatively low price and cost, relatively small footprint, and increasing power density. and ECP contractors, and with the continuous update and improvement of outdoor inverter dustproof and waterproof measures, it has gradually become the main product of photovoltaic inverter manufacturers. [0003] At present, for the 3.1...
