Installing Battery Expansion Modules
2.3
•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.
Install the remaining battery modules and power module from bottom to top. After
installing a module, secure the left and right connecting pieces, and then install the
next module.

Connect the ground
points of modules in
sequence, and secure
the ground cable using
a ground screw.
Insert the positive and
negative connectors
into the positive and
negative battery
cascading terminals
(B+ and B–).
•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.

Before connecting external
cables, route the cables
through the cable hole to
avoid disconnecting after
installation.
Cut a cable hole based on
the cabling mode, and route
external cables through the
cable hole.
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.

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.

COM Port Pin Definitions
The COM port definitions on both sides of the power control module are the same. It is
recommended that the COM port on the switch side be connected to the inverter and the COM port
on the other side be connected to the cascaded battery.
•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.
