XOLTA system
state diagram
5.3.1.2 Run state
The run state is the operational state of the XOLTA Outdoor BESS. In this state, it is able to receive/
sent power from/to batteries according to the associated algorithms defined by the user’s chosen
mode (section 5.2). If there is no charge/discharge request for about 20 seconds, then the inverter
will switch to standby.
If the system is left inactive (inverter P,Q = 0) for a longer period (20 min), then it will automatically
transition to the sleep state.
5.3.1.3 Error state
If a fault is detected, the system will immediately switch to the error state. A series of actions will then occur:
• Immediate shutdown of inverter, DC and AC contactors open
• BMS is disabled, DC relay open
• Report error to the XOLTA cloud
If the fault can be resolved internally, then the system will return to the state it was in when the error
was diagnosed and carry on the task it was previously executing.
5.3.2 Transitional Sequences
5.3.2.1 Initialization
Accessible from POR (Power-on Reset) or from the error state in the event of a fault reset as shown
in Figure 5.7. During this sequence the following occurs:
• Check of all communication lines of ESS, internal (serial busses) and external (cloud/energy meters)
• Status check of all devices
• In case of error, reset the device showing the error
• Activate BMS
Once the sequence is complete, the system automatically transitions to the Sleep state.
5.3.2.2 Startup
Accessible from sleep state and transitions the system to the run state. During this sequence, the
following occurs:
• Inverter is activated
• BESS DC contactors close
• AC and DC contactors of inverter close
