Load > 125% : alarm reported and output switched off after 5s.
12
AC output reverse
Prevents AC back flow from the battery inverter to the bypass AC
input.
13
Bypass over-current
protection
Built-in AC input over-current protection circuit breaker.
14
Bypass phase
inconsistency
protection
When the phase of the bypass input and the phase of the inverter
split do not match, the inverter disables switching to the bypass
output to prevent the load from dropping out or short-circuiting
when switching to the bypass.
15
Charging short-circuit
protection
When the external battery port is short-circuited in the PV or AC
charging state, the inverter will protect and stop the output current.
16
Parallel connection error
protection
In parallel operation, the equipment will be protected when the
parallel line is lost.
17
Parallel battery voltage
difference protection
In parallel operation, the equipment will be protected when the
battery connection is inconsistent and the battery voltage is greatly
different from that detected by the host.
18
Parallel AC voltage
difference protection
In parallel operation, the equipment will be protected when the AC
IN input connection is inconsistent.
19
Synchronization signal
fault protection
The equipment will be protected when there is a fault in the
guidance signal between parallel buses, causing inconsistent
behavior of each inverter.
