Remember the usage, maintenance, and upkeep requirements for lithium-ion battery UPS systems, and you can extend their lifespan by several years! Many users buy UPS power supplies but don't know how to maintain and care for them. In fact, proper use and maintenance can significantly extend the lifespan of your UPS by several years. How can you ensure comprehensive use, maintenance, and upkeep of your lithium-ion battery UPS? We'll answer your questions one by one.
1. Environmental requirements for lithium-ion battery UPS
▲The placement must be stable;
▲The UPS chassis must maintain sufficient ventilation distance from the walls on all sides;
▲Keep away from heat sources, direct sunlight, and non-corrosive substances;
▲ Maintain normal temperature and humidity;
▲Keep the room clean.
2. When using a UPS, the size and characteristics of the load must be considered.
The rated output power of a UPS is an important parameter indicating how much power load the product can drive. It varies with the load power factor. For example, a 1kVA UPS may not be able to drive a 1kVA load. In order to extend the service life of a lithium-ion battery UPS, the UPS should not be operated at full load for a long time.
Standby UPS systems are typically selected for 60% to 70% of their rated power load, while online UPS systems are typically selected for 70% to 80% of their rated power load. UPS systems should also not be operated under excessively light load conditions for extended periods.
3. Implement measures to protect the UPS from induced lightning strikes.
Lightning strikes are the bane of all electrical appliances; therefore, it is crucial to ensure effective shielding and grounding protection for UPS systems. Lightning damage is primarily caused by a series of reactions resulting from air-to-ground or air-to-air discharges from thunderclouds. When clouds discharge, nearby overhead power lines and communication lines experience induced high-potential pulses due to electromagnetic induction. These high-potential pulses travel along the power lines or communication lines into the UPS. Since UPS systems utilize numerous CMOS integrated circuit modules and microelectronic devices such as CPUs for control, they are highly sensitive to lightning electromagnetic pulses and are easily damaged. Therefore, even with effective shielding and proper protective grounding of the UPS, it is essential to ensure adequate lightning overvoltage protection for power lines and communication lines.
4. Precautions for the use, maintenance, and upkeep of lithium-ion battery UPS
▲ Do not connect inductive loads to the UPS output port.
▲ When using a UPS power supply, you must comply with the relevant regulations in the product manual or user manual, and ensure that the connected live wire, neutral wire, and ground wire meet the requirements. Users must not arbitrarily change their order.
▲ Strictly follow the correct power-on and power-off sequence. This prevents the UPS power supply from malfunctioning due to large voltage fluctuations caused by sudden load loading or unloading.
▲Frequent switching of the UPS power supply on and off is strictly prohibited. Generally, after switching off the UPS power supply, wait at least 6 seconds before switching it back on. Otherwise, the UPS power supply may enter a "start-up failure" state, meaning that the UPS power supply will enter a state with neither mains power output nor inverter output.
▲ Overloading is prohibited. The maximum starting load of the UPS power supply should ideally be kept below 80%. Overloading can frequently damage the inverter diodes in inverter mode. Experience has shown that for most UPS power supplies, controlling the load within 30-60% of the rated output power is the optimal operating mode.
▲ Battery discharge requirements. Most UPS systems have battery discharge protection measures. After discharging to the protection shutdown point, the battery can recover to a certain voltage, but restarting is not allowed at this point, otherwise it will cause over-discharge of the battery. The UPS must be recharged before it can be put into normal use.
▲ Newly purchased UPS (or UPS that has been stored for a period of time) must have its batteries charged before it can be put into normal use. Otherwise, backup time cannot be guaranteed.
▲For UPS systems that operate without power outages for extended periods, the UPS should be discharged and then recharged every 3 to 6 months. This will extend the battery's lifespan.
▲For UPSs stored for a long time, they should be turned on and charged every 3 to 6 months, otherwise the UPS main unit and battery will be damaged.
▲Perform regular maintenance on the UPS power supply. This includes cleaning accumulated dust inside the unit, measuring the battery voltage, checking fan operation, and testing and adjusting UPS system parameters.
The above is a fairly comprehensive introduction to the use, maintenance, and upkeep of lithium-ion battery UPS power supplies. Please remember these methods; mastering them will ensure your UPS power supply lasts at least ten years. Of course, this assumes you choose a power supply manufacturer with guaranteed quality and excellent after-sales service.
