General Requirements
D ANGER
Do not work with power on during installation.
● Do not install, use, or operate outdoor equipment and cables (including but
not limited to moving equipment, operating equipment and cables, inserting
connectors to or removing connectors from signal ports connected to outdoor
facilities, working at heights, and performing outdoor installation) in harsh
weather conditions such as lightning, rain, snow, and level 6 or stronger wind.
● After installing the equipment, remove idle packing materials such as cartons,
foam, plastics, and cable ties from the equipment area.
● In the case of a re, immediately leave the building or the equipment area,
and turn on the re alarm bell or make an emergency call. Do not enter the
building on re in any case.

to an outdoor environment for a long period of time.
● Do not open the host panel of the equipment.
● Without prior consent from the manufacturer, do not alter the internal
structure or installation procedure of the equipment.
● Ensure that battery terminal components are not aected during
transportation. Do not hoist or move batteries by using battery terminal bolts.
Personal Safety
● Wear proper personal protective equipment (PPE) during operation. If there is
a probability of personal injury or equipment damage, immediately stop the
operations, report the case to the supervisor, and take feasible protective
measures.
● Use tools correctly to avoid hurting people or damaging the equipment.
● Do not touch the energized equipment, as the enclosure is hot.
● To ensure personal safety and normal use of the equipment, the equipment
must be reliably grounded before use.
● When a battery is faulty, the temperature may exceed the burn threshold of
the touchable surface. Therefore, avoid touching the battery.
● Do not disassemble or damage the battery. The released electrolyte is harmful
to your skin and eyes. Avoid contact with the electrolyte.
● Do not place irrelevant objects on the top of the equipment or insert them
into any position of the equipment.

● To prevent explosions and body injury, do not place batteries in a re.
● Do not place the battery module in water or other liquids.
● Do not short-circuit wiring terminals of batteries. Short circuits can cause a
re.
● Batteries may cause electric shocks and high short-circuit currents. When
using the battery, pay attention to the following points:
(a) Remove any metal objects from yourself, such as watches and rings.
(b) Use tools with insulated handles.
(c) Wear rubber gloves and boots.
(d) Do not place tools or metal parts on top of batteries.
(e) Before connecting or disconnecting battery terminals, disconnect the
charging power supply.
(f) Check whether batteries are accidentally grounded. If it is accidentally
grounded, remove the power supply from the ground. Touching any part of a
grounded battery can cause an electric shock. If these grounding points are
removed during installation and maintenance, the possibility of electric shocks
can be reduced.
● Do not use water to clean electrical components inside or outside of a
cabinet.
● Do not stand on, lean on, or sit on the top of the equipment.

2 Product Introduction
2.1 Overview
Function
The LUNA2000 battery consists of a power control module and battery expansion
modules. It can store and release electric energy based on the requirements of the
inverter management system. The input and output ports of the LUNA2000
battery are high-voltage direct current (HVDC) ports.
● Battery charge: The power control module connects to the battery terminals
(BAT+ and BAT–) of the inverter. Under the control of the inverter, the power
control module charges the batteries and stores excessive PV energy in
batteries.
● Battery discharge: When the PV energy is insucient to supply power to the
loads, the system controls the batteries to supply power to the loads. The
battery energy is output to the loads through the inverter.
