## Abstract

A solar power inverter having a sealing means includes: a main case having an opening on a front surface thereof, the opening open and closed by a main cover; an auxiliary case coupled to one side surface of the main case, and having a second opening on a front surface thereof, the second opening open and closed by an auxiliary cover; and a gasket interposed between the main case and the auxiliary case, wherein the main case and the auxiliary case are coupled to each other by coupling bolts which pass through the main case, the gasket and the auxiliary case.

## Claims

### Claim 1

A solar power inverter having a sealing means, comprising:
a main case having an opening on a front surface thereof, the opening open and closed by a main cover;
an auxiliary case coupled to one side surface of the main case, and having a second opening on a front surface thereof, the second opening open and closed by an auxiliary cover; and
a gasket interposed between the main case and the auxiliary case,
wherein the main case and the auxiliary case are coupled to each other by coupling bolts which pass through the main case, the gasket and the auxiliary case,
wherein part of contact surfaces of the main case and the auxiliary case is blocked by the main cover,
wherein a flange protrudes from a side wall on an outer circumference of the main case, and
wherein the main cover is coupled to the flange, and disposed such that an end of the main cover contacts the front surface of the auxiliary case.

### Claim 2 (depends on 1)

The solar power inverter having a sealing means of claim 1, wherein the gasket is formed of a silicon material.

### Claim 3 (depends on 1)

The solar power inverter having a sealing means of claim 1, wherein one of the main cover and the auxiliary cover extends to the contact surfaces of the main case and the auxiliary case.
