The IP rating of an inverter refers to the level of protection it provides against the intrusion of solid objects (such as dust) and liquids (such as water). It is usually expressed as “IP” followed by two digits, where the first digit represents the level of protection against solids and the second digit represents protection against liquids.
When selecting an inverter for a solar energy system, one important factor to consider is its IP (Ingress Protection) rating. The IP rating indicates how well the inverter is protected against dust, moisture, and other environmental factors.
Let’s examine how the IP rating affects an inverter’s suitability for outdoor and harsh environments. An inverter with a high first-digit rating (e.g., IP65 or IP66) provides complete protection against dust and dirt, preventing it from entering the unit and causing internal damage.
The protection measures for the overvoltage of the inverter vary according to the cause of the overvoltage of the inverter. For the overvoltage phenomenon generated during the parking process, if there is no special requirement for the parking time or position, it can be solved by extending the deceleration time of the inverter or free parking.
The higher the number, the better the protection. For example, an IP65 rating means the inverter is completely dust-tight (level 6) and has no entry of dust particles that could affect its performance. To learn more about solid protection levels, visit here 1.
An inverter with a high first-digit rating (e.g., IP65 or IP66) provides complete protection against dust and dirt, preventing it from entering the unit and causing internal damage. This is particularly important in areas with heavy dust or pollution, as dirt particles can interfere with the inverter’s cooling system or internal electronics.
