2. Introduction to Product
2.1 Intended Purpose
The battery is a 6.5kWh LiFePO4 pack. It has a 48V battery module as
the main power supply unit which composed of 32 pieces of 64Ah cells
in two parallel and sixteen serial connect (2P16S). Battery coordinates
with PV, PCS, Grid, DC Breaker and loads in the residential energy
storage system. The four typical application scenarios are as shown
Battery powers loads at nighttime
when there is no PV. If battery
energy is insufficient, it can
supply loads together with grid.
Battery can be charged by grid.
Users are suggested to store
energy from grid to battery when
electricity price is relatively lower.
＊ Power-off triggered by fault: battery powers off if level three
under voltage, 0V cell or parallel connection failure happens.
＊
Forced power-off: when battery does not connect to mains
supply, press POWER button for two seconds and battery
powers off.
＊
Activation: input 48V-57.6V/2S-5S via P+/P- terminals, battery will
be activated from off mode to standby status.
2.3 Appearance
The battery is an energy storage unit composed of cells, mechanical
parts, battery management system (BMS) as well as power and signal
terminals. Product dimension (unit: mm) and appearance are as
shown below:
2.2 Function
Compared with normal batteries, the battery is characterized with
better charging and discharging performance, longer cycle life and
less self-discharging loss. The build-in BMS can monitor battery
operation status and alarm timely to avoid operation out of limit. A
maximum of 8 batteries can be parallel-connected to expand energy
and power of energy storage system. Battery realizes communication
with PCS via CAN or RS485 network port.
＊
Monitoring: detect the voltage and temperature of cell, the
voltage and current of battery.
＊
SOC estimate: indicate the precise volume of remaining
electricity.
＊
Alarm: alarm when overvoltage, under voltage, overcurrent,
over temperature or under temperature occurs.
＊
Protection: protect against over voltage, under voltage, over
current, over temperature, under temperature, cell fault and
hardware failure.
＊ Report: report alarm messages and operation data to PCS via
CAN or RS485 network ports.
＊
Parallel connection: support a maximum of 8 batteries in
parallel connection.
The energy produced by PV is
optimized to supply loads. The
excess energy is used to charge
battery, then export to grid.
When grid falls, battery and PV
can power loads.
Each battery shall be equipped with an two-pole DC breaker as:
Rated Voltage ≥ 120Vdc Rated Current ≥ 150A
Cut-off current: 2200A
!
CAUTION
Breakers are provided by your system supplier.
The quantity of breakers must be consistent with that of the battries.
