interface:
)1.Reset button:to start the battery pack, hold the button for 2s to turn on battery pack.
)2.RS485 communication interface:RJ45 port, follow RS485 protocol. For transmitting battery pack information between paralleled packs. The first 4 DIP switches (#1, #2, #3, #4) are used for identifying packs’ information on software.
)3.CAN 5 communication interface:follow CAN BUS protocol, for output pack information to inverter. One pack should be assigned as master pack. And the last 4 DIP switches (#5, #6, #7, #8) to tell how many slave packs are followed. The firs DIP switches are used for identifying slave packs.
)4.ADS Switch:To setup battery address for identification, and make the communicate between batteries, battery to inverter.
)5.NOTE:There are 8 bit DIP switches, keep the switch on down side means ‘OFF’, turn up the switch to top sidemeans 'ON’
)6.ALARM light:red LED flash to show the battery alarm status. And red light to show the battery in protection status of abnormal temperature, over-current, or short-circuit.
)7.Working light:green LED to show the battery working status.
)8.SOC light:4 green LED lights to show the capacity status of battery pack. Each LED represents 25% the capacity.

Power terminals
Power terminals:
two pairs of power terminals with the same function, one connect to equipment, and the other one parallel to other battery pack for capacity expanding. For a single pack, both terminals can achieve charging and discharging functions.
note:Power cable uses 6.0mm power plug with lock button. And can be full rotation.
Battery features:
Qcepower3.2V 280Ah lithium iron phosphate (LiFePO4) aluminum case prismatic rechargeable battery cell.
Nominal Voltage | 3.2V |
Nominal Capacity | 280Ah |
Weight | ≤5.5Kg |
Self-discharge Rate | ≤3.5% per month |
Initial Internal Resistance（1KHz） | ≤0.25mΩ |
Qcepower Technology applies high quality Grade A cells inside the battery box. And did the following designs to prolong the battery pack cycle life.
| According to the test report, if the battery pack is charged and discharged at 0.5C, the battery pack can reach more than 6,000 cycles of 1000 times when the remaining capacity is 80% at room temperature at 25°C. |
Advanced Battery Management System (BMS):
The BMS is applied to monitor current, voltage, temperature, protection against over-charge, over-discharge, over-current, over-temperature, under-temperature and short circuit. The BMS provides cell balancing and current limitation during charging process to ensure a reliable safety and performance. |
BMSFunction introduction:
)1.Over charge protection
)2.Over discharge protection
)3.Over current protection
)4.Cell balancing
)5.Temperature protection
)6.CAN and RS485 communication
Monitoring software:
Battery pack can be remotely monitored with BATTERYMONITOR software. With this software, battery voltage, cell voltage of single cell and pack, SOC status, cell temperature, voltage differences can be monitoring in real time. Through history record, battery status can be checked afterwards.
First, connect Qcepower to the master computer with USB-RS485adapter. If the adapter needs wiring, follow the wiring diagram.
Compatible Inverters:
Battery pre-programmed with multiple CAN protocols to compatible with multi-brands of inverters. To make sure that the battery module works perfectly, it would be better to use the compatible inverters listed below. |
Note:
Different models of inverters may comes with different protocols and designing even for the same brand. For some models, a firmware updating is required for perfect communication. |
