5.5.4 RS485 Communication connection
The power storage inverter contains two 485 interfaces, with one for external WiFi and
GPRS communication, and the otherfor lithium battery communication.
Please connect the RS-485 communication following the below steps:
(1)
Remove the water-proof components of RS-485 with screwdriver.
(2)
Loosen the nut.
(3)
Disassemble the single-aperture sealing ring.
(4)
Pass the cable successively through the nut, single-aperture sealing ring, insulator and she
e
metal parts.
(5)
Insert eight wire cores of the cable into the corresponding slot of crystal head (refer
t
Figure 23), and then clamp with tools.
(6)
Connect the crystal head that is clamped to RS-485 port in the inverter.
(7)
Attach the water-proof component of RS-485 to the inverter.
(8)
Tighten the nut.

7. Working modes
The machine has three kinds of working modes: self-generation and self-consumption, battery
priority, and peak load shifting.
7.1 self-generation and self-consumption
When solar energy is sufficient, power converted by inverter (from solar energy) will first be
used to supply the load，with the residual for batteries and then the grid; If solar energy is
inadequate, power stored in batteries and PV energy will support the load altogether; as night
falls, batteries and mains supply will provide power for the load.
7.2 Battery priority
Power converted by inverter from solar energy will first be used to charge the battery, with the
residual power for the load.
7.3 Peak load shifting
The energy will be stored when the electricity price is low, which can be utilized when price
high; the timing control of machine charging and discharging may also be carried out based on
the actual usage.
7.4 Instructions for the use of three modes
(1) Before selecting the mode, you can set it up according to the local power grid, PV input
mode and battery type.
Power grid：
Stand-by off off off off
Hybrid power
connection on off off off
Off-network off on on off
Bypass of mains flash off on off
Fault off off off on

Note: If there are requirements for reactive power in the locality, please refer to 8.2.4 and set
up in line with the actual needs.

After the Restart interface appears, the machine will return to the selection interface of
three working modes;
If more items are to be set up, restart after finishing the setting.
Battery priority：
Note: When choosing battery priority mode, the corresponding charging current should
be opted for according to the battery type. The system default current is 20A.
Peak load shifting：
After finishing the setting of Peak load shifting mode,the charging and discharging time
also needto be set up.
Note:If the time is set up incorrectly, the system will pop up an interface indicating the setting
error. Charging and discharging time will return to the state prior to setting.
