How do Xtalent maintain battery life when charging batteries?

The Fangpusun Xtalent Hybrid Inverter /Charger has UPS functions when connected to batteries. In combination, it can use the AC terminal to charge batteries and can be used as an energy storage device. So how does the Xtalent inverter function and charge the battery to ensure the service life of the battery?

 

Xtalent has multiple electronic protections for batteries when working

1. Low pressure protection

If the battery voltage is lower than the overdischarge protection voltage value {1108} set by us, and the duration reaches the value {1190} set by us, the inverter will stop the inverter output to prevent deep battery discharge.

2. Battery undervoltage dynamic compensation

Xtalent has an intelligent algorithm to automatically calculate battery voltage compensation based on instantaneous power, and the compensation mode can be set to manual compensation by setting {1532}.

3. Overvoltage protection

If the battery voltage exceeds the user set value {1121}, the inverter will stop running and start again when the voltage is less than {1110}. If Xtalent encounters this situation three times in a minute, it will stop running permanently and can only be started again by manual control of the operator.

4. Prevent reverse battery connection

XTM and PSM series inverters use internal fuses to prevent polarity reverse connection. When polarity reverse connection occurs, the fuses of XTM and PSM series inverters will break, thus protecting the battery and other equipment.

Xtalent uses AC power to charge the battery, using different charging modes in different states of the battery, which helps to prolong the life of the battery and ensure the state of the battery.

What is the four-stage charging mode?

1. In the first stage, the fast charge 'bulk' is used to quickly charge the battery with the maximum (100%) output current of the smart charger. The charging time depends on the battery capacity and battery status when charging starts.

2. In the second stage‘absorption’, the smart charger reaches 90% of batteries (80% of wet batteries). This phase lasts approximately 4 hours (AGM and GEL batteries) with the battery charged to 100%.

3. When the battery is fully charged, the smart charger automatically transfers to the third stage "floating" charging mode, which keeps the battery in the best condition while supplying power to the connected load. If the use current exceeds the power available from the smart charger, the battery starts to partially discharge, and the smart charger automatically transfers to the first stage (" bulk "). The smart charger switches to the three-stage charging system again.

4, balanced charging: balanced charging is a small current (1/20C20A) for 1~3h charging process. It is mainly used to eliminate a group of floating charging operation (that is, DC power supply and battery parallel connection working mode) battery in the same operation condition, due to some reason caused by the whole group of battery imbalance and the formation of the difference, in order to achieve the balance of the whole group of batteries. This method is generally not frequently used, but when the battery occurs in one of the following situations, it must be balanced charging:

A .The battery is not charged in time after discharging current for A long time, or it is charged with DC charge for A long time.

B. When the voltage and electrolyte density of a single cell of the battery are low and the whole battery group is different.

C .Charge and discharge are not performed according to the specified period.
