‘Seamless switch’ must be enabled if users want the load to be transferred seamlessly to the inverter

backup power.

‘No Battery’ can be enabled to use solar power to supply load when the grid fails or load-shedding hap-

pens. If users do not have a battery installed yet but still wish to have inverter backup power with only

solar panels connected, this setting can be enabled.

‘Micro-grid’ should be set only when the generator is connected to the inverter’s Grid terminal. With

this option enabled, the inverter will use AC power to charge the battery and will not export any power

through the Grid terminal if AC power is present at the inverter’s Grid terminal.

‘Charge last’ will use solar power in the following order: 1. Loads> 2. Grid export> 3. Battery charging.

‘CT direction reversed’ occurs when both CTs are installed in the wrong direction; the installer can rem-

edy this by checking this box.

‘Role’ setting of the parallel system.

It is set to ‘1 phase master’ by de-

fault. In a parallel system, only one

inverter is allowed to be set as

Master and the others are set as

Slaves.

‘Phase’ is the phase code setting of

the load output. The system will

automatically detect the phase se-

quence of the inverter (consistent

with the phase sequence of the

connected grid mains) and display it on the inverter after it is connected to the grid.

‘Share battery’: If all inverters are connected to the same battery bank when configured as a parallel

system, then this setting must be enabled. If the inverters are configured as a parallel system and are

connected to independent battery banks, then this setting must be disabled.

Reminder:

• All setting changes for parallel inverters must be done while in Standby Mode.

• If the system is connected to a lithium battery, the host of the battery bank needs to

communicate with the inverter that is set as Master in the parallel system.

• Keep all the settings the same for each inverter in the parallel system on the LCD or remote

monitor!

Inverter Start-Up and Shutdown Procedure

11.4.1 Starting up the inverter

1. If equipped, turn on(close) the DC breaker between battery and inverter first. Turn on the BAT

breaker located in the cable box of the inverter and then power on the battery system.
