2. Float charging starts when the battery is close to a full charge the B801 attempts to apply a constant float voltage maintaining a near 100 charge If the battery loads are consuming more power than the input power coming from the REbus DC Microgrid then the battery voltage will decrease When the battery voltage reaches the user defined Re bulk voltage the B801 will enter Bulk charging mode again The B801 will always cycle through the three charging states Bulk Absorption and Float 7 4 5 Equalize After the battery bank experiences repeated charging cycles the individual cells that make up each battery become unbalanced and some hold more charge then others In order to maximize the lifetime and total energy storage of your battery bank you must Equalize the battery bank Equalization brings all of the individual cells within a battery to the same voltage This is done by holding the battery bank at a slightly higher voltage then the Bulk Voltage This does not harm the batteries in any way and it is part of typical battery maintenance Equalization is initiated manually by the user and stops after the equalization time has elapsed It is recommended to perform equalization periodically and during a 17 time with steady input power Please check with the battery manufacturer about maintenance and equalization best practices Ensure batteries have sufficient electrolyte levels before performing an equalization cycle 7

6. 5 Battery Voltage Limits Battery systems often have multiple sources for battery charging such as a PV system and or a generator It is important that all these systems are configured with the same battery voltage setpoints so that each part of the system can perform the correct task at the correct time The B801 is constantly monitoring the battery bank voltage if it is out of a safe range the B801 will take action to prevent damage to the batteries There are a variety of ways the B801 safely handles dangerous battery voltages 7 5 1 Low Battery Voltage A user adjustable low battery voltage setpoint determines the Low Battery Voltage Threshold For a 48V system the default Low battery voltage is 47V For a 24V system the default Low Battery voltage is 23 5V The charge controller must draw a small amount of power to keep the REbus DC microgrid at 340V so that input devices such as the T701 Wind Turbine and the S2001 PV Link can still operate During low battery voltage state if there isn t any input power the B801 will power down the REbus DC microgrid to OV in order to conserve power The B801 enters a hibernation state and will wait a specified amount of time before bringing the voltage on the REbus DC microgrid back to 340V again The off time and on time for when the REbus DC microgrid is at OV or 340V are specified in the user setpoint table refer to Table 1 User Setpoint Table for more information about setpoin
