FAQs:
Q. How to determine the current status (charging/discharging)?
A. When the current value on the LCD is negative it means the Module is discharging and when it is
positive, it means the Module is charging.
Q. The current reading on the LCD is not accurate for the first charging/discharging Session?
A. The user should wait for 5 minutes after starting the Module for the first charge/discharge session
(it is only one time for warming up).
Q. How to reset the current to zero?
A. Please refer to section 2.3 in User Manual.
Q. If we leave the Module turned ON after it reaches 44V or below. What will happen?
A. When the Module reaches the minimum voltage and below (whether terminal is ON or OFF), the
LCD will display “Low Charge Module” message. (Please
refer to Low charge module section in user
manual).
Q. What will happen if the Module is totally empty? or If the Module is left on after it is drained,
will it keep draining to the point that it will not charge without some sort of manual recovery?
A. Getting Module totally empty (zero voltage) after leaving the Module stand by for long time is
normal, so in this case LCD & electronic switch will be OFF, but the Module can be recovered. (Please
refer to recovery procedure in the user manual).
Q. Self-consumption of the Module when connected to a power source and the terminal is ON, seem
to consume about 1Amp or about 1kWh per day?
A. The maximum current of the Module BMS is 60mA not 1A.
Q. We are getting multimeter value different (Voltage, Current Charge/discharge, Temperature,
Energy) from that displayed in LCD across the terminal? or why has the Module lost the calibration?
A. It is normal since each electronic tool or equipment needs calibration after long time of use to get
accurate results, and for that the Module needs to be calibrated. But before that please check the
following:
•
Firstly, double check the value with accurate meter (we suggest Fluke multimeter), if the deviation
between the Module and multimeter is less than ±0.5% it is acceptable.
•
Secondly, if the deviation is more than ±0.5%, the Module needs calibration. Please consult with
your Reseller for calibration.
Q. What could happen when connecting different model of Sirius Module parallel/series together?
A. Modules can be connected in parallel or in series if they will have:
- Same Voltage
- Same Capacity
