display “Low Charge Module” message. (Please refer to Low charge mod
ule 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
It is possible but not recommended especially connecting old BMS design to the new one. The system might
get unpredictable during extreme scenarios like Module charge full or low.
Q. Is it possible to connect Sirius Module in parallel with other chemical batteries such as lithium-ion or lead
acid?
A. It is possible but not recommended. Make sure the total voltage of each battery is the same as the Module
and
the charging voltage does not exceed the Module’s maximum voltage. The possible drawback is that you
will not get the total capacity of the chemical battery because extreme voltages are not the same.
Q. If we set the cutoff voltage on the charge controller systems /inverter end to 45V, will that allow the
Module to sit at idle for longer periods of time to avoid an undervoltage situation.
A. Yes.
Q. How to check charging/discharging energy of Module?
A. Please refer to “
Overview of Sirius
VIEW Application” section in
Sirius VIEW application manual.
Q. Why the Module needs twice of power cycle?
A. When the Module is switched OFF and the Sirius VIEW is still open you have to wait for 10 Sec (since the
application is still communicating with the Module) before turning ON the Module, or either by terminating
the Sirius VIEW or by disconnecting the communication cable.
Q. How much is the capacity of the internal storage (SD Card)?
A. 8GB SD Card is used in the Module which logs 85 bytes of data per 10 seconds. Note that data logging should
be turned ON before the Module will start logging and data logging is limited to 30 days. After reading the
data the Module will delete it automatically. By default, data logging is OFF for firmware version 2. 0 and
