Remember the maintenance and upkeep requirements for lithium-ion battery UPS, which can extend its lifespan by several years! Many users do not know how to maintain and upkeep their UPS power supply after purchasing it. In fact, proper use and maintenance can greatly extend the lifespan of your UPS power supply by several years. How to achieve comprehensive maintenance and upkeep of lithium-ion battery UPS? The editor will answer each of you one by one soon.
1. Environmental requirements for the use of lithium-ion battery UPS
▲ The placement position must be stable;
The UPS chassis must maintain sufficient ventilation distance from the walls on all sides;
▲ Keep away from heat sources, no direct sunlight, and no corrosiveness;
Maintain normal temperature and humidity;
▲ Keep the room clean.
2. When using UPS, the size and characteristics of the load must be considered
The rated output power of UPS is an important parameter that indicates how much power load the product can drive. It varies with the change of load power factor. For example, a 1kVA UPS may not necessarily be able to drive a 1kVA load. In order to extend the service life of lithium-ion battery UPS, UPS should not be operated at full load for a long time.
Backup UPS generally selects a load capacity of 60% to 70% of the rated power, while online UPS generally selects a load capacity of 70% to 80% of the rated power. At the same time, UPS should not operate under excessive light load for a long time.
3. Do a good job in preventing induced lightning damage to UPS
Lightning strikes are the natural enemy of all electrical appliances, and it is important to ensure effective shielding and grounding protection of UPS. Thunder damage is mainly caused by a series of reactions triggered by lightning cloud air to ground or air to air discharge. When clouds discharge, nearby overhead power lines and communication lines will experience induced high potential pulses due to electromagnetic induction. These high potential pulses enter the UPS along power or communication lines, and the UPS uses a large number of CMOS integrated circuit modules and microelectronic devices such as control CPUs, which are very sensitive to electromagnetic pulses from lightning and are therefore easily damaged. On the premise that UPS has effective shielding and good protective grounding, it is necessary to do a good job of lightning protection and overvoltage protection for power lines and communication lines.
4. Precautions for the use, maintenance, and upkeep of lithium-ion battery UPS
▲ It is prohibited to connect inductive loads to the UPS output port.
When using UPS power supply, it is necessary to follow the relevant regulations in the product manual or user manual to ensure that the live wire, neutral wire, and ground wire connected meet the requirements, and users must not change their mutual order arbitrarily.
Strictly follow the correct startup and shutdown sequence for operation. To prevent the voltage output of the UPS power supply from fluctuating greatly due to sudden loading or unloading of the load, which may cause the UPS power supply to malfunction.
▲ It is strictly prohibited to frequently turn off and turn on the UPS power supply. It is generally required to wait for at least 6 seconds after turning off the UPS power supply before turning it on. Otherwise, the UPS power supply may enter a "startup failure" state, that is, the UPS power supply enters a state where there is neither mains power output nor inverter output.
▲ Overloading is prohibited. The maximum starting load of UPS power supply should be controlled within 80%. If overloaded, the inverter tube may often break down in the inverter state. Practice has proven that for the vast majority of UPS power supplies, controlling their load within the range of 30-60% of rated output power is the optimal operating mode.
▲ Discharge requirements for batteries. Generally, UPS has protective measures for battery discharge, but after discharging until the protective shutdown, the battery can recover to a certain voltage. However, it is not allowed to restart at this time, otherwise it will cause over discharge of the battery. UPS must be recharged before it can be put into normal use.
Newly purchased UPS (or UPS stored for a period of time) must be charged before it can be put into normal use. Otherwise, backup time cannot be guaranteed.
For UPS with long-term uninterrupted power supply, the UPS should be discharged and then recharged every 3 to 6 months. This can extend the lifespan of the battery.
For UPS stored for a long time, it should be turned on and charged every 3-6 months, otherwise the UPS host and battery will be damaged.
Regularly maintain the UPS power supply. Clean up the dust inside the machine, measure the voltage of the battery pack, check the operation of the fan, and detect and adjust the system parameters of the UPS.
The above is a comprehensive introduction to the use, maintenance and upkeep of lithium-ion battery UPS power supply. Friends must remember and learn these methods. Your UPS power supply can have a service life of at least ten years without any problem. Of course, this prerequisite is that you have to choose a power supply manufacturer with guaranteed quality and thoughtful after-sales service.
