The northern regions of Bangladesh, especially the Rajshahi district, experience hot summer months with temperatures regularly peaking above 40°C. In such extreme conditions, traditional lead-acid or standard lithium-cobalt chemistry suffers accelerated degradation. Ansar Energy utilizes strictly Grade A Lithium Iron Phosphate (LiFePO4) chemistry, which offers unmatched thermal stability, non-flammability, and outstanding chemical endurance.
Integrated smart Battery Management System with active cell balancing, monitoring over-current, over-charge, over-discharge, and high-temp triggers to ensure 100% cell protection.
Optimal thermal performance engineered for tropical operations, showing zero capacity fade at 35°C ambient, and safely operating at peak surges up to 60°C.
Seamless CAN/RS485/RS232 communication compatibility with major global inverter brands like Deye, Growatt, SMA, Voltronic, and Victron Energy.
In addition to standard products, Ansar Energy provides OEM and ODM manufacturing services, offering customized battery capacities, system configurations, branding solutions, and project-specific energy storage designs. The company collaborates closely with solar installers, energy developers, distributors, and system integrators worldwide.
Our wall-mounted lithium energy solutions cover capacity configurations ranging from 2.5kWh up to 10.24kWh per unit. Designed for space-saving vertical wall configurations, these units can be easily connected in parallel (up to 15 modules) to power large commercial setups.

Driven by innovation, sustainability, and customer-focused engineering, Shenzhen Ansar Energy Co., Ltd. is dedicated to delivering reliable solar energy storage solutions that help customers achieve greater energy independence, operational efficiency, and long-term renewable energy value. Every single unit undergoes a strict aging cycle, vibration tests, high/low-temperature checks, and visual enclosure inspections in our ISO 9001-certified factory in Shenzhen before being securely packed for dispatch.
Procuring energy storage products from China requires strict compliance with international shipping protocols for dangerous goods (Class 9 UN3480 classification) as well as complying with Bangladesh customs regulations. Our dedicated logistical framework handles shipping channels from Shenzhen port directly to Chittagong or Mongla port, followed by customs cleared inland transit directly to distributors and sites across Rajshahi, Rangpur, and Dhaka divisions.
Fully certified under UL1973, CE, UN38.3, and IEC62619 guidelines. Ready for test reports required by IDCOL and BUET in Bangladesh.
Double-wall heavy duty cartons with molded foam inserts. Shock-absorbent shipping crates designed specifically for maritime transport routes.
Online engineering support. Quick dispatch of BMS modular spares and circuit boards directly to your service points in Rajshahi.
