Moistureproof photovoltaic inverter and control system thereof

Abstract

The invention belongs to the field of photovoltaic inverters, and particularly relates to a moistureproof photovoltaic inverter and a control system thereof.The moistureproof photovoltaic inverter comprises a protection shell and a photovoltaic inverter body, the photovoltaic inverter body is fixedly connected with the inner side of the protection shell, a control panel is fixedly installed on the outer side of the protection shell, a ventilation box is fixedly installed at the rear end of the protection shell, and the ventilation box is fixedly installed on the inner side of the protection shell. The two ends of the ventilation box are open, absorbent cotton is fixedly installed on the inner side of the ventilation box, and part of moisture in air entering the ventilation box from the outside can be intercepted by the absorbent cotton, so that passing of water vapor can be effectively reduced, and the situation that the device is affected with damp and damaged due to the fact that the water vapor intrudes into the inner side of the device is prevented; the dehumidification assembly can be started, air on the inner side of the device is sucked into the inner side of the device, water vapor in the air is condensed into water drops through condensation, dry air is exhaled, dryness of the inner side of the device is further guaranteed, and therefore the device can be protected from being affected by humid air.

Description

technical field [0001] The invention belongs to the field of photovoltaic inverters, in particular to a moisture-proof photovoltaic inverter and its control system. Background technique [0002] A photovoltaic inverter is a device used to connect photovoltaic equipment and convert the direct current generated in the photovoltaic equipment into alternating current. [0003] A Chinese patent with the publication number CN112104197A discloses a photovoltaic inverter, which includes a photovoltaic inverter body and a splash-proof casing. The two sides of the splash case are ventilated so that the inside of the splash-proof case can always be in a state of ventilation, but under natural conditions, the interior of the case will not enter water due to splashing, creating a good use for the photovoltaic inverter environment. [0004] Existing photovoltaic inverters still have some disadvantages. Since photovoltaic inverters are often installed outdoors, the outdoor environment is...

Problems solved by technology

[0004] Existing photovoltaic inverters still have some disadvantages. Since photovoltaic inverters are often installed outdoors, the outdoor environment is usually relatively high in humidity, which can easily lead to moisture intrusion into the inside of the device, causing moisture damage to the inside of the device.
