Battery Cables Connection
2.1
Connecting the Battery Cables to the Battery Pack
NOTICE
Make sure that the Auxiliary Power ON/OFF switch and the Circuit Breaker switch of the battery pack are turned off before connecting
the power cable to the battery pack.
Make sure that the inverter AC and DC disconnections are turned off before connecting the power cable to the battery pack.

a)Connect the ground wire to terminal 1.
b)Connect the negative line of the power cable to terminal 2.
c)Connect the positive line of the power cable to terminal 3.
At first, connect the wire to terminal 2. Then, make
connections to the 3, 4, and 5 terminals one after another.
2.2
Connecting the Battery Cables to the SUN2000L
DANGER
Do not connect or disconnect battery cables when the SUN2000L is running. Failing to do so may cause electric shocks.
Before connecting battery cables, ensure that the DC switch on the SUN2000L and all the switches connecting to the SUN2000L are OFF,
and the SUN2000L has no residual electricity. Otherwise, the high voltage of the SUN2000L and battery may result in electric shocks.
If no battery connects to the SUN2000L, do not remove the watertight cap from the battery terminal. Otherwise, the SUN2000L willnot
comply with its Ingress Protection Rating. If a battery connects to the SUN2000L, set aside the watertight cap. Reinstall thewatertight cap
immediately after removing the connector. The high voltage of the battery terminal may result in electric shocks.

WARNING
Do not connect any load between the SUN2000L and the battery.
Ensure that the following conditions are met. Otherwise, the SUN2000L will be damaged, or even become a fire hazard.
The battery cable is connected correctly. That is, the positive and negative terminals of the battery connect to the positive battery terminal
and negative battery terminal on the SUN2000L respectively.
The cable between the battery and the SUN2000L should be less than or equal to 10 meters, and within 5 meters is recommended.
The battery voltage can result in fatal injury. Use dedicated insulation tools to terminate cables.
Ensure that the battery cable is correctly connected. Avoid reverse polarity.

Powering On the System
the battery pack in operation by taking the following steps:
a)Turn on the Auxiliary Power ON/OFF switch after installing the battery pack. Make sure that the Circuit Breaker switch is in theOFF
position (including the Trip position).
b)Set the Circuit Breaker switch to the ON position.
Auxiliary Power ON/OFF switch Circuit Breaker switch
c)Several seconds after the Circuit Breaker switch is set to ON, 4 LEDs will be lit.
d)Make sure that ON indicator is on and see if the battery pack is successfully initialized. The power-on indicator on the front should turn on
in green.
e)Close the wiring box cover.

on the SUN2000L:
NOTICE
.
Before turning on the AC switch between the SUN2000L and the power grid, check that the AC voltage on the power grid side of the AC
switch is within the specified range.
If the DC is on and the AC is off, the SUN2000L reports a Grid Failurealarm. The SUN2000L starts normally only after the fault is rectified.
If the AC is on and the battery is off, the SUN2000L reports a Battery Abnormal alarm.

NOTICE
If the SUN2000L is connected to the battery, after turning on the AC switch:
If the DC switch is turned on within 1 minute, the SUN2000L will run properly in grid-tied mode.
If the DC switch is not turned on within 1 minute, the SUN2000L will enter the nighttime grid-tied mode. Then, after the DC switch is
turned on, the SUN2000L will shut down and then restart to run in grid-tied mode.
c)Turn on the DC switch between the PV string and the SUN2000L if there is any.
d)Turn on the DC switch at the bottom of the SUN2000L.
e)Perform quick setting over the FusionHomeapp. There are two methods to add the device. Method 1: tap Go to set after quick setting is
complete, and then configure parameters on the Add/Delete device 2: on the Operation consolescreen, choose Device
maintenance > Add/Delete device, and add the deviceaccording to actual conditions.

Powering Off the System
off the SUN2000L:
WARNING
After the SUN2000L powers off, the remaining electricity and heat may still cause electric shocks and body burns. Therefore, puton
protective gloves and begin servicing the SUN2000L 5 minutes after the power-off.
If the SUN2000L is connected to the battery, ensure that a shutdown command is sent from the app. Power off the system after the
SUN2000L has shut down. If no shutdown command is sent from the app, the SUN2000L will shut down after the power grid is
powered off. Then, the SUN2000L will wait for 1 minute and restart (not grid-tied) to charge the battery, which poses the risk of turning
off the DC switch with power.
a)Send a shutdown command from the app. If you log in as installer, on the Operation console screen, choose Device maintenance >
Inverter ON/OFF, and perform operations as required; if you log in as user, on the main screen, choose > Setmaint> Inverter
ON/OFF, and perform operations as required.

Connecting the Battery Cables to the SUN2000L
DANGER
Do not connect or disconnect battery cables when the SUN2000L is running. Failing to do so may cause electric shocks.
Before connecting battery cables, ensure that the DC switch on the SUN2000L and all the switches connecting to the SUN2000L are OFF,
and the SUN2000L has no residual electricity. Otherwise, the high voltage of the SUN2000L and battery may result in electric shocks.
If no battery connects to the SUN2000L, do not remove the watertight cap from the battery terminal. Otherwise, the SUN2000L willnot
comply with its Ingress Protection Rating. If a battery connects to the SUN2000L, set aside the watertight cap. Reinstall thewatertight cap
immediately after removing the connector. The high voltage of the battery terminal may result in electric shocks.

WARNING
Do not connect any load between the SUN2000L and the battery.
Ensure that the following conditions are met. Otherwise, the SUN2000L will be damaged, or even become a fire hazard.
The battery cable is connected correctly. That is, the positive and negative terminals of the battery connect to the positive battery terminal
and negative battery terminal on the SUN2000L respectively.
The cable between the battery and the SUN2000L should be less than or equal to 10 meters, and within 5 meters is recommended.
The battery voltage can result in fatal injury. Use dedicated insulation tools to terminate cables.
Ensure that the battery cable is correctly connected. Avoid reverse polarity.

NOTICE
.
Before turning on the AC switch between the SUN2000L and the power grid, check that the AC voltage on the power grid side of the AC
switch is within the specified range.
If the DC is on and the AC is off, the SUN2000L reports a Grid Failurealarm. The SUN2000L starts normally only after the fault is rectified.
If the AC is on and the battery is off, the SUN2000L reports a Battery Abnormal alarm.

If the SUN2000L is connected to the battery, after turning on the AC switch:
If the DC switch is turned on within 1 minute, the SUN2000L will run properly in grid-tied mode.
If the DC switch is not turned on within 1 minute, the SUN2000L will enter the nighttime grid-tied mode. Then, after the DC switch is
turned on, the SUN2000L will shut down and then restart to run in grid-tied mode.
c)Turn on the DC switch between the PV string and the SUN2000L if there is any.
d)Turn on the DC switch at the bottom of the SUN2000L.
e)Perform quick setting over the FusionHomeapp. There are two methods to add the device. Method 1: tap Go to set after quick setting is
complete, and then configure parameters on the Add/Delete device 2: on the Operation consolescreen, choose Device

Powering Off the System
off the SUN2000L:
WARNING
After the SUN2000L powers off, the remaining electricity and heat may still cause electric shocks and body burns. Therefore, puton
protective gloves and begin servicing the SUN2000L 5 minutes after the power-off.
If the SUN2000L is connected to the battery, ensure that a shutdown command is sent from the app. Power off the system after the
SUN2000L has shut down. If no shutdown command is sent from the app, the SUN2000L will shut down after the power grid is
powered off. Then, the SUN2000L will wait for 1 minute and restart (not grid-tied) to charge the battery, which poses the risk of turning
off the DC switch with power.
a)Send a shutdown command from the app. If you log in as installer, on the Operation console screen, choose Device maintenance >
Inverter ON/OFF, and perform operations as required; if you log in as user, on the main screen, choose > Setmaint> Inverter
ON/OFF, and perform operations as required.
