Product Overview
2.6 Working State
The series inverter has Waiting, Checking, Normal, EPS Checking, EPS, Fault, Idle and
Standby state.
Table 2-3 Description of working state
State Description
Waiting
The inverter is waiting for the following two conditions to be met
in order to enter the 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 state.
EPS • The inverter is working in off-grid state.
Fault • The inverter detects error occured and prompts error code.
Idle
• The the battery SOC reaches the minimum SOC and there is no
sufficient PV input voltage, etc.
Unusual Idle
• The battery needs to be charged but PV and grid power are not
allowed to charge the battery
Standby
• A standby state 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 10% and there is no sufficient PV input voltage.
• In this state, it detects PV connection, load power, etc to
determine whether to exit Standby state and enter Normal state.
