The enclosure of charge controller
The enclosure of charge controller:
If the controllers are used indoors or outdoors but with box, user can choose IP30 solar controller. For outdoor application, sometimes steam condenses to water when it touches a cold surface. And the water can come into controllers along with the wire. So it’s better to use high IP rating controller in humid area.
What is an IP rating?
IP (or "Ingress Protection") ratings are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture. The numbers that follow IP each have a specific meaning. The first indicates the degree of protection (of people) from moving parts, as well as the protection of enclosed equipment from foreign bodies. The second defines the protection level that the enclosure enjoys from various forms of moisture (drips, sprays, submersion etc).
First Digit (Solid particle protection)
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects

1 |
Dripping water |
Dripping water (vertically falling drops) shall have no harmful effect. |
Test duration: 10 minutes Water equivalent to 1mm rainfall per minute |
2 |
Dripping water when tilted up to 15° |
Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position. |
Test duration: 10 minutes Water equivalent to 3mm rainfall per minute |
3 |
Spraying water |
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. |
Test duration: 5 minutes
Water volume: 0.7 litres per minute |
4 |
Splashing water |
Water splashing against the enclosure from any direction shall have no harmful effect. |
Test duration: 5 minutes
Water volume: 10 litres per minute |
5 |
Water jets |
Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects. |
Test duration: at least 3 minutes
Water volume: 12.5 litres per minute |
6 |
Powerful water jets |
Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects. |
Test duration: at least 3 minutes
Water volume: 100 litres per minute |
7 |
Immersion up to 1 m |
Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion). |
Test duration: 30 minutes Immersion at depth of 1m |
8 |
Immersion beyond 1 m |
The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. |
Test duration: continuous immersion in water Depth specified by manufacturer |
