Product Overview
2.6 Working State
The series inverter has Waiting, Checking, Normal, EPS Checking, EPS, Fault, Self-testing,
Upgrading, Idle and Standby state.
Table 2-3 Description of working state
State Description
Waiting
• The inverter is waiting for the conditions to be met in order to
enter Checking state.
Checking
• The inverter is checking for conditions to enter Normal state.
Normal • The inverter is working normally.
EPS Checking
• The inverter is checking for conditions to enter EPS (off-grid)
state.
EPS • The inverter is working in EPS (off-grid) state.
Fault • The inverter detects error and prompts error code.
Self-testing • The inverter is self-testing. (Only applicable for CEI 0-21)
Upgrading • The inverter is upgrading DSP, ARM, or BMS.
Idle
• When the battery SOC reaches the minimum SOC and there is
no sufficient PV input voltage, the battery goes into hibernation
and the inverter enters Idle state.
Standby
• When the power of load is extremely low and there is no
sufficient PV input voltage, or a state when the battery SOC is
more than or equal to 10% and there is no sufficient PV input
voltage, the inverter enters Standby state.
• In this state, it detects PV connection, load power, battery forced
charged, etc to determine whether to exit Standby state and
enter Normal state.
NOTICE!
• When the inverter is in an idle state, you can reset the working mode, the Min SOC
and the charging periods through the inverter LCD or the SolaX APP to charge the
battery to the Min SOC in the charging periods and then awaken the inverter. Please
make sure that the actual battery SOC minus the modified Min SOC is ≥ 2% under a
specific working mode, so that other modifications are effective. When the current
system time is within the new charging periods you reset, the battery begins charging.
