NOTICE:
When a Master Module is offline in a fault state, or has been manually shutdown, the entire cluster
will go offline until the Master comes back online.
To restart the Cluster, it is mandatory to repeat the Cluster Start Up procedure. First make sure to
shut down all batteries by setting the power switch to the off (0) position, then set all power switches
to the ON (I) position and press the Master RUN BUTTON to enable the startup process again.
NOTICE:
In a parallel battery system, we strongly advise not to switch off individual sub batteries when the
system is running, either in Charge or Discharge Mode as this process might affect the
communication between modules and inverter.
Switching off an individual sub battery in a parallel system is possible in an adverse situation, but
only as a last resort and prior switching off the solar inverter
3.3.3 Battery recover from Under Voltage state – Force Charge
Prerequisite: The VOLTAGE between the battery B + and B- terminals is ZERO and the PANEL LIGHTS ARE OFF. Battery is
in “Shutdown State” and 90 seconds after pressing the button, the battery will enter the shutdown mode once again.
Preparation condition before forced charging: Connect the charger or the inverter with charging capability to the B+ and
B- of the Battery Module to ensure charging capacity.
Forced charging approach: By shortly pressings the Battery Module Run Button, the battery RUN light will flash GREEN
which means that the battery is entering the compulsory charging mode. If the battery receives adequate charging power
(above 10 Amps/Max 58Vdc) within 90 seconds from pressing the button, the battery will continue to charge normally until
a stable state is reached.
If the battery does not receive adequate charging power within 90 seconds after pressing the button, the battery will
enter the shutdown mode once again.
3.4 LV Direct Parallel Connection WITHOUT Certified Inverter BMS Communication
(Open-Loop)
As per the Limited Performance Warranty document, CAN communication between inverter and battery is
mandatory. Refer to Models listed in Section 3.6 of this manual.
Performance Warranty is not applicable for non CAN-BMS connected batteries
Read Limited Warranty document.
