How to Maintain Huawei Sun 2000 5ktl M1 5000w

Photovoltaic inverter is one of the core equipment of the photovoltaic system, and its maintenance and maintenance will greatly improve the service life of the system and reduce costs. Therefore, the correct use and maintenance of photovoltaic inverters can not only ensure the normal operation of the inverter, but also improve the service life of the equipment.
So, how should we properly maintain and maintain the photovoltaic inverter?

In order to ensure the long-term stable operation of the system, it is necessary to use and maintain the photovoltaic inverter correctly and reasonably. If the inverter cannot be used and maintained reasonably, it will directly affect the performance of the photovoltaic system. Therefore, for ordinary users, it is very necessary to carry out daily maintenance and maintenance of photovoltaic inverters. Let’s talk about how to carry out daily maintenance and maintenance in combination with common problems in daily work:

If the inverter cannot be used and maintained reasonably, it will directly affect the performance of the photovoltaic system. Therefore, for ordinary users, it is very necessary to carry out daily maintenance and maintenance of photovoltaic inverters. Let’s talk about how to carry out daily maintenance and maintenance in combination with common problems in daily work:

• The inverter should be installed in a well-ventilated environment with an ambient temperature of 5-40°C and an air humidity of less than 90%;
• The inverter should be installed in a dry, dust-free, non-corrosive gas and rain-proof, snow-proof outdoor environment;
• The inverter casing should be kept clean and free from rust;
• The inverter should be installed on the level ground, and cannot be placed directly on the concrete floor or platform to avoid damage to the equipment. There cannot be any other objects behind the inverter;
• The inverter will generate a lot of heat during operation, so the inverter will vibrate when it is running. If there is vibration, stop the machine immediately for inspection, and if there is abnormal vibration, it must be inspected or repaired. Do not touch the circuit board part or the case with your hands, and do not touch the circuit board part or the case with wet hands.

• It should be used according to the weather and environmental conditions, and should not be used in heavy rain or when the air humidity is too high;
• During the operation of the inverter, it is not allowed to adjust the output without authorization;
• It is strictly forbidden to change the string, output and settings of the device without permission;
• It is strictly forbidden to use high-power electrical appliances to prevent damage to the input power factor and internal circuits of the inverter;
• Do not disassemble or move any parts on the inverter at will, especially prevent hard objects from entering the inverter, so as not to damage the equipment and affect performance;
• Always clean the dust on the inverter to prevent dust from entering the circuit.

• Choose reliable inverters and components;
• Minimize the downtime of equipment failure;
• Try to avoid frequent replacement of inverters and components;
• Frequently check the working conditions of the inverter and components, find faults and eliminate them in time;
• These are one of the important factors to ensure reliable operation of the inverter. Often, substandard inverters and components cause the PV system not to work properly, resulting in reduced power generation.
• Regularly clean and dedust the photovoltaic inverter to avoid dust accumulation, so as not to affect the service life of the equipment.
• Frequently check whether the photovoltaic inverter and components are damaged, and replace them in time. If it is found that it cannot work normally, stop using the device immediately and notify relevant personnel in time to deal with it.

• In order to prevent the equipment from being subjected to electric shock and damage to the equipment, it cannot be operated under direct sunlight. When there is large solar radiation, the system can be turned off to prevent the equipment from being sunburned;
• When the equipment is running, the output voltage and current of the inverter must be adjusted in time according to the running status, and the relevant information on the equipment must be paid attention to. In case of abnormality or error information, the inverter should be cut off immediately and reported to relevant personnel;
• Keep the area around the inverter clean and dry to avoid the intrusion of humid air; Avoid overloading the inverter during operation;
• Do not touch the electrical components inside the inverter with your hands.

• The inverter should be checked regularly, especially under direct sunlight or strong direct sunlight, to prevent overheating and aging of the internal components of the inverter.
• Regularly check the DC voltage output by the inverter, and it should not exceed 80% of the rated value.
• Regularly check and remove dust and other dirt in the photovoltaic grid-connected inverter system.
