Products Description

Seplos solar lithium battery module CANBUS/RS485 24/48v 8S-16S 50A/100A/150A/200A lithium battery protection board Cell monitoring system

1. We can provide seplos CANBUS/RS485 24V/48V 50A/100A/150A/200A Lifepo4/NCM BMS,for prismatic or Cylindrical lithium battery pack

2.We can provide two kinds of BMS boards with different communication modes, one is BMS using CANBUS communication protocol and the other is BMS using RS485 communication protocol, so that customers can have more flexible choices

3.Our BMS can support up to 16 units in parallel operation.

4.The main functions are: CANBUS communication、RS485 communication、Passive balance、Individual cell over voltage protection、Over （under）voltage protection、temperature protect、over charge（discharge） protection, over current protection, Short circuit protection etc.

Attention: when we want to view the battery pack parameters through the battery parameter monitoring software, we need to use the Rj45 to USB Adapter to connect the battery pack to the computer. We recommend that you purchase an Rj45 to USB Adapter from us.Adapters purchased from the market may not work properly due to the definition of the hardware

Communication methods

CANBUS mother board

Now our CANBUS communication board supports these brands of inverters,and our BMS has built-in CANBUS protocol of matching inverter brand, which can be automatically matched or manually switched:

*The default is the Pylontech CANBUS protocol

* Goodwe
* Growatt (The default is SPF(off-grid) protocol. If your inverter is SPH(on-grid) , please contact the sales person)
* Victron
* LUX POWER
* Sofar
* DEYE
* Sermatec
* RENAC
* TBB POWER
* SOLIS
* SMA
* FoxESS

* IMEON

If the inverter brand not in the listed, please ask your inverter supplier for the protocol define. And sent it to us, we'll help confirm that.

RS485 mother board

Now our RS485 communication board supports these brands of inverters,The BMS with RS485 communication has a built-in RS485 protocol, please confirm with the salesman before buying what you need is that one RS485 protocol.

*The default is the Pylontech RS485 protocol

* Voltronic

* Phocos

* Growatt

If the inverter brand not in the listed, please ask your inverter supplier for the protocol define. And sent it to us, we'll help confirm that.

Company Introduction

Shenzhen Seplos Technology Co., Ltd. was established on June 8, 2017, by SmartBli, Yihua, Zhongxi, Biliyuan and ihigee
, WTT company investment, was rated as an international brand

Establish the Seplos Manufacturing Group in China. In this group, Seplos With prismatic battery factory, BMS factory,
Packaging factory and r & D company. Seplos focuses on the development of solar cell storage systems for home use and provides some great solutions for both products.
The main markets for SEplos are ERU, the United States and Australia.

Lithium-ion batteries are becoming a way of life, gradually replacing lead-acid batteries in essential applications such as
electric vehicles and energy storage. However, having been engaged in the lithium-ion battery industry for a long time, and
hearing the terrible news of lithium-ion battery explosions and fires randomly, Seplos Technology is fully aware of the safety issues of lithium-ion battery applications. Therefore, Seplos chose lithium iron Phosphate (LiFePO4, or LFP) to develop our product line, which is proven to be one of the safest chemicals in all lithium-ion batteries.
Seplos is committed to providing high quality low voltage storage batteries with the principle of "safety first". To achieve this goal, Seplos has assembled a team of professional engineers, optimized our supply chain, and developed regional agents to provide timely service.
