strong impact force. Otherwise, safety risks
(such as cell leakage and electric shock) may
arise.

•The following describes how to install the battery expansion modules for a 15 kWh model.
•The installation of battery expansion modules for 5 kWh and 10 kWh models is the same.
One battery expansion module is installed for a 5 kWh model, and two battery expansion
modules are installed for a 10 kWh model.
1. Install the battery expansion modules and power control module on the support.
Align the first battery
expansion module with
the support on the floor
support.
Install the connecting
pieces on both sides
and tighten the four
screws.

Connect the ground
points of modules in
sequence, and secure
the ground cable using
a ground screw.
•Connect cables in accordance with local installation laws and regulations.
•Before connecting cables, ensure that the DC switch on the battery and all the switches
connected to the battery are set to OFF. Otherwise, the high voltage of the battery may result
in electric shocks.
3Internal Electrical Connections of the Battery
•Internal electrical cables are delivered with the battery, see the Packing List in the packing case.
•The Amphenol terminal is used as the DC terminal between the power control module and the
battery expansion modules.

•When a communications terminal is connected to a single network cable, a waterproof rubber
plug must be installed. Do not install a cable with a diameter of 5 mm into a Ф7 mm rubber
plug, the 7 mm hole is used to connect to an inverter or cascaded battery.
•After inserting the terminal shell into the COM port, shake the terminal shell left and right
and pull it back to ensure that it is securely installed, and tighten the nut (ensure that the
rubber plug is tightly compressed). Otherwise, the waterproof performance is affected.

Install the internal signal cables described in this section using the three signal cables with a
diameter of 5 mm and rubber plugs delivered with the DCDC. Do not use signal cables with a
diameter of 7 mm.

Routing Cables Out of the Cable Hole
4.2
Before connecting external cables, route
the cables through the cable hole to avoid
disconnecting after installation.
Prepare cables based on site requirements.
•Ground a ground point of the power control module.
•Apply silica gel or paint around the ground terminal after the ground cable is connected.

•Before connecting cables, ensure that the DC switch on the battery and all the switches
connected to the battery are set to OFF. Otherwise, the high voltage of the battery may result
in electric shocks.
•The DC input power cable and signal cable between the battery and the inverter must be less
than or equal to 10 m.

Installing DC Input Power Cables
Use dedicated insulated tools to connect cables. Ensure that battery cables are connected to
correct polarities. If the battery cables are reversely connected, the battery may be damaged.
1. You are advised to connect the battery terminals (BAT+ and BAT–) on the switch side to the
inverter and connect the other side to the cascaded battery.
2. The battery terminals use the Staubli MC4 positive and negative metal terminals and DC
connectors supplied with the solar inverter. Using incompatible positive and negative metal
terminals and DC connectors may result in serious consequences. The caused device damage is
not covered under warranty.

•When laying out a signal cable, separate it from power cables and keep it away from strong
interference sources to prevent communication interruption.
•Ensure that the protection layer of the cable is inside the connector, that excess core wires
are cut off from the protection layer, that the exposed core wire is totally inserted into the
cable hole, and that the cable is connected securely.
•Use a plug to block the idle cable hole with the waterproof rubber ring, and then tighten the
locking cap.
•If multiple signal cables need to be connected, ensure that the outer diameters of the signal
cables are the same.

Communications Terminal Description
It is recommended that the right side of COM port be
connected to the inverter and the left side of the COM port
be connected to the cascaded batteries. The communications
terminal insertion directions on the left and right side of the
COM port are different. Insert the communications terminals
in the directions shown in the figures.

Product Overview
6System Power-On
•To prevent the device from being exposed to high humidity in the power-off state, you are
advised to power on the LUNA2000 within 24 hours after unpacking it. The period for which the
device remains powered-off during maintenance must not exceed 24 hours. Otherwise,
condensation may cause damage to the device.
•After turning on the battery switch, power on the inverter. For details about how to power on
the inverter, see the quick guide for the corresponding inverter model.
•If no PV module is configured, press the black start button.
Turn on the DC switch on the battery. After the battery is installed and powered on for the first
time, the ring LED blinks for three circles. Observe the battery indicator to check the running status.
