Solarmi Energy storage system LiFePO4 EEL-A01, 51.2V/14.3kWh, 4A active BMS, LV

EEL-A01 Battery 14.3 kWh with active 4 A balancer

EEL-A01 battery
The battery is unique in that it uses cells with a longer cycle life than other, smaller capacity batteries on the market. It is made of 16 selected branded cells from EVE. The cells are not traditionally laser-welded, but screwed together, which allows for extended real-life durability and potential repairability. Please read this manual carefully so that the battery serves you for many years to your satisfaction.

Transport
Transport the battery to its destination using four handles and four people. When using handling equipment, the handles must not be used due to the possibility of uneven loading, overloading of the handles, and potential battery drop. Do not overestimate your own strength and ensure assistance from other people during transport.

Installation and setup
Electrical installation and inverter setup must be carried out by a qualified professional.

Instructions for connecting Deye Inverter with EEL battery

Communication connection
Cable: Use the included cable that comes with the inverter, or any other LAN Ethernet RJ-45 network cable.
Ports: Connect the cable to the BMS port on the Deye inverter and to the CAN socket on the battery. Deye settings: On the Deye inverter, select Lithium mode. Leave the address on Deye at the default value of 00.

Parallel battery connection
DIP switches: For parallel connection of multiple batteries, it is necessary to set the DIP switches.

Example for 2 batteries
For the main battery (Master), set DIP switch 5 up.
For the secondary battery (Slave), set DIP switch 1 up.
Cable connection: Connect the batteries to each other with the same LAN cable. From the master's rightmost 485 socket to the middle socket on the slave battery.

Power connection
Option 1: Connect the batteries with a short cable plus to plus and minus to minus. Then lead cables from the first battery to the inverter (plus from the first battery and minus from the second battery).
Option 2: Lead a 50 mm2 cable from each battery to one point, for example to a DC disconnector or fuses. There, join the pluses and minuses together and then lead with one stronger cable (70 mm2) to the inverter.

Summary
This procedure will allow you to safely and effectively connect the Deye inverter to your battery system. Make sure all connections are firm and secure, and that the settings on the device are correct to ensure proper system functionality.
The battery has screw terminals for 8mm cable lugs.
