Battery Charging Information

 

Bulk Charge

In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is used to charge the battery. 12·Boost Charge When the battery has recharged to the Boost voltage setpoint, constant- current regulation 

is used to prevent heating and excessive battery gassing. The Boost stage remains 120 minutes and then goes to Float Charge. Every time when the controller is powered on, if it detects neither over discharged nor overvoltage, the charging will enter into boost charging stage.

·Float Charge

After the battery is fully charged in Boost voltage stage, the controller reduces the battery voltage to Float voltage set point. When the battery is fully recharged, there  will be no more chemical reactions and all the charge current transmits into heat and gas at this time. 

Then  the controller  reduces the voltage to  the floating stage, charging with  a smaller voltage and current. It will reduce the temperature of battery and prevent the gassing, also charging the battery slightly at the same time. The purpose of Float stage is to offset the power consumption caused by self consumption and small loads in the whole system, while maintaining full battery storage capacity. 

In Float stage, loads can continue to draw power from the battery. In the event that the system load(s) exceed the solar charge current, the controller will no longer be able to maintain the battery at the Float setpoint. Should the battery  voltage remains below the boost reconnect charging voltage, the controller will exit Float stage and return to Bulk charge.

·Equalize Charge

Certain types of batteries  benefit from periodic equalizing charge, which can stir  the electrolyte, balance battery voltage and complete chemical reaction. Equalizing charge increases the battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte.Every month 28th solar controller will  engender  equalize charging stage. It will remain 120mins when  equalize stage is  constant,  or it will  remain 180mins when  equalize charging accomplishes off and on. Equalize charge and boost charge are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of battery.

Protection

·PV Array Short Circuit
If PV array short circuit occurs, clear it to resume normal operation.

·Load Overload
If the load current exceeds the maximum load current rating, the controller will disconnect the load. Overloading must be cleared up through reapply power or pressing the setting button.

·Load Short Circuit
Fully protected against load wiring short-circuit. After one automatic load reconnect attempt, the fault must be cleared by reapply power or pressing the setting button.

·PV Reverse Polarity
Fully protection against PV reverse polarity, no damage to the controller will result. Correct the mistake connection to resume normal operation.

·Battery Reverse Polarity
Fully protection against battery reverse polarity, no damage to the controller will result. Correct the mistake connection to resume normal operation.

·Damaged Local Temperature Sensor
If the temperature sensor short-circuited or damaged, the controller will be charging or discharging at the default temperature 25℃ to prevent the battery damaged from overcharging or over discharged.

·Overheating Protection 
If the temperature of the controller heat sink exceeds 85C, the controller will automatically start the overheating protection. It recover after it drops to 80C. 

·High Voltage Transients
PV is protected against high voltage transients. In lightning prone areas, additional external suppression is recommended.
