Avoid drilling holes in the utility
pipes and/or cables attached
to the back of the wall.
Support-mounted Installation
Wall-mounted Installation
You are advised to
apply anti-rust paint
on the hole
positions for
protection.
If the bottom of the mounting plate does not snap into place, push the SUN2000L from the
front until the bottom of the mounting plate snaps into the mounting bracket.
The anti-theft lock needs to be prepared by the customer.
1. Install the SUN2000L on the
mounting bracket. 2. Tighten screw assemblies. 3. (Optional) Install an anti-theft lock.
Prepare M8 stainless bolt assemblies (including flat washers, spring washers, and M8 bolts) with
appropriate lengths as well as matched flat washers and nuts based on the support specifications.
3 Connecting Cables

3.1
The PE point at the AC output port is used only as a PE
equipotential point, and cannot substitute for the PE point
on the enclosure.
Recommended: Apply silica gel or paint around a ground
terminal after connecting the ground cable.

Prepare cables based on site requirements.
Do not connect the neutral wire to the enclosure as a PE
cable. Otherwise, electric shocks will be caused.
Connect cables in accordance with the installation laws and regulations
of the country or region where the SUN2000L is located.
Before connecting cables, ensure that the DC switch on the SUN2000L
and all the switches connecting to the SUN2000L are OFF. Otherwise,
the high voltage of the SUN2000L may result in electric shocks.

Installing the DC Input Power Cable
3.4
1. Ensure that the PV module output is well insulatedto ground.
2. The SUN2000LDC input voltage must always be lower than or equal to 600 V DC.
3. Before installing the DC input power cable, label the cable polarities correctly to ensure
correct cable connections.
4. Use the positive and negative metal terminalsand black DC connectorssuppliedwith the
SUN2000L.Using other modelsof positive and negative metal terminalsand DC
connectors may result in serious consequences. The caused device damage is not
covered under any warranty or service agreement.
5. If polarity of the DC input power cable is reversedand the DC switch is ON, do not turn
off the DC switch immediatelyor unplug positive and negative connectors.The device
may be damagedif you do not follow the instruction. This damage is not covered under
any warranty or service agreement. Wait until the solar irradiance declines at night and
the PV string current reduces to below 0.5 A, and then turn off the DC switch and remove
the positive and negative connectors. Correct the string polarity before reconnectingthe
string to the SUN2000L.

NOTICE
When laying out signal cables, separate them from power cables to avoid strong signal interference sources.
The protection layer of the signal cable is in the connector. Surplus core wires are cut off from the protection layer. The exposed core wire
is totally inserted into the cable hole and connected securely.
Do not confuse the connector to the COM port and the connector to the ALARM port.
If a connector needs to connect to only one signal cable, block the unused cable hole in the seal using a cap and tighten the cable gland.
If a connector needs to connect to two signal cables, ensure that the cables have the same outer diameter.

NOTICE
To remove the AC connector from the SUN2000L, perform the operations in reverse order.
The right figure shows how to remove a plug insert.
NOTE
The battery voltage will result in fatal injury. Use dedicated
insulation tools to terminate cables.
Ensure that the battery cable is correctly connected. Avoid
reverse polarity.
Assemble the blue positive and negative connectors by following the instructions in section 3.4 "Installing the DC Input Power Cable."
Pull the battery cable back to ensure
that it is connected securely.

4 Verifying the Installation
1. Turn on the AC switch between the SUN2000L and the power grid.
2. Turn on the DC switch between the PV string and the SUN2000L if there is any.
3. Turn on the DC switch at the bottom of the SUN2000L.
4. If a battery connects to the battery terminals, turn on the power switch on the battery, and
then turn on the battery switch.
5. Perform quicksetting over the appby referring to the SUN2000LAppQuickGuide.
6. (Optional) Measure the temperatures at the joints between the DC terminals and the
connectors using a point-test thermometer.
7. Observe the LEDs to check the SUN2000L operating status.
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.
