1.3 Working Principle and Function
The APX distinguishes itself with better charging and discharging performance, higher
charging and discharging efficiency, higher flexibility in capacity expansion, more
accurate status monitoring, longer service life, and less self-discharge loss.
ŸParallel connection: Support the parallel connection of one to six Battery Modules.
ŸReport: Report alarms and status data to the hybrid inverter.
ŸSystem power-off: 12 minutes after the communication between the battery system and
the hybrid inverter is disconnected.
The APX 5.0-30.0P-S0 high voltage battery system is composed of a Power Module APX
55027-P0 and multiple Battery Modules APX 5.0P-B1 connected in parallel. It contains
electrochemical batteries, battery control units, power control units, battery management
units, power and signal terminals, and mechanical parts.
ŸMonitoring: Monitor the voltage, current and temperature of each battery module and
the battery system.
ŸBattery cell balancing: passive battery balancing.
The APX system can connect 1 to 6 Battery Modules in parallel to increase the capacity and
power of the battery system; The APX system communicates with the hybrid inverter
through RS485 communications.
ŸProtection and Alarm: Generate alarms and provide protection in cases of overvoltage,
undervoltage, overcurrent, over-temperature or under-temperature.
ŸBattery Module balancing: intelligent power distribution, active balancing
When installing or using a battery system, observe the safety precautions provided in this
section. For personal safety, the operation personnel must read through this manual and
observe the safety instructions.
2.1 General safety
ŸDamage caused by improper operations in transportation, storage, installation and use,

ŸDamage due to force majeure, such as lightning, earthquakes, fire, and storms.
ŸWarranty expiration.
2.2 Safety Precautions
2.2.1 Environment requirements
ØDo not expose the battery to temperature above 50°C or heat sources.
ØThe battery system must be protected from liquids.
ØDo not expose the battery to direct sunlight for extended periods of time.
ØDo not place the battery in a fire, which may cause an explosion.
ØDo not install or use the battery in wet environment with moisture, corrosive gases or
liquids, such as in the bathroom.
ØPlace the battery in a safe place and ensure that the battery is not accessible to children
and animals.
ØBattery power terminals shall not come in contact with conductive objects such as
wires.
