2 Overview
iPack C3.3 is a 3.3 kWh standalone LiFePO4 battery pack. It has a 48V battery module as the main power
supply unit composed of 64 Ah cells in one parallel and 16 serial connect (1P16S)
.
Battery coordinates with
PV, power conversion system (PCS), Grid, DC Breaker and loads in the residential energy storage system.
2.1 Application Scenarios
The typical application scenarios are as shown below.
The energy produced by PV is optimized to
supply loads. The excess energy is used to
charge battery, then export to grid.
Battery powers loads at nighttime when there
is no PV. If battery energy is insufficient, it can
supply loads together with grid
.

Junction Box
When grid falls, battery and PV can power
loads.
Battery can be charged by grid. Users are
suggested to store energy from grid to battery
when electricity price is relatively lower.
2.2 Product Features
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 6 batteries can be parallel-connected
to expand energy and power of energy storage system. Battery realizes communication with PCS via CAN
network port.
