Engineered for Chittagong's unique coastal grid demands, presenting modern lithium energy storage solutions built to maximize solar yield and energy independence.
Bridging the gap between unstable power grids and high-density growth in Bangladesh's commercial gateway.
As Bangladesh's primary port city and second-largest metropolis, Chittagong (Chattogram) serves as the engine of the nation's import-export economy. Home to the bustling Chittagong Export Processing Zone (CEPZ), critical heavy industries, and rapidly expanding residential sectors like Halishahar, Khulshi, and Nasirabad, the city's power demands have outpaced grid development. Grid instability, voltage sags, and seasonal load shedding pose persistent challenges to both residential comfort and commercial uptime.
Historically, businesses and homeowners relied on diesel generator sets and conventional lead-acid Instant Power Supply (IPS) units. However, these systems present significant drawbacks in the modern energy paradigm: high operational fuel costs, noise pollution, high emissions, short lifespans, and low round-trip efficiency (RTE). In response, the local market is rapidly pivoting toward advanced Lithium-ion Residential Energy Storage Systems (ESS). These modern systems offer a zero-emission, silent, and highly efficient solution to buffer grid volatility while maximizing rooftop photovoltaic (PV) utilization.
Provides instantaneous back-up power during blackouts, ensuring uninterrupted operations for domestic appliances and critical home office infrastructure.
Charges during low-tariff off-peak hours and discharges during expensive peak hours, offering substantial savings on electricity bills.
LiFePO4 battery chemistry yields up to 6,000 charge cycles, outlasting traditional lead-acid alternatives by more than five times.
Engineered to withstand high humidity, coastal salinity, and elevated temperatures.
Chittagong's coastal monsoon climate presents harsh environmental conditions, characterized by high relative humidity (often exceeding 85%) and high ambient temperatures. For electronic equipment like hybrid inverters and lithium-ion batteries, these factors increase the risk of condensation, internal corrosion, and thermal runaway if not properly addressed.
Our residential energy storage systems are engineered with IP65-rated enclosures and advanced thermal management systems to ensure reliable performance under these conditions. The cell management architecture incorporates active balancing, liquid or optimized air cooling channels, and multi-tier Battery Management Systems (BMS) to monitor cell temperature, state of charge (SoC), and state of health (SoH) in real time.
Scalable power systems that address residential, commercial, and microgrid demands.
Hunan June Power Technology Co., Ltd. designs and manufactures systems tailored to diverse installation environments. From residential villas seeking energy independence to light commercial settings in Chittagong's textile and trading districts, our systems provide scalable energy storage options designed to optimize local power networks.
Our engineering team can model your load profile, regional solar irradiance, and blackout patterns to design an optimized energy storage package.

Streamlining transportation, custom clearances, and regulatory compliance for Bangladesh importers.
Importing large-scale lithium-ion energy storage systems requires navigation of complex chemical freight regulations and local electrical import standards. Because LiFePO4 batteries are classified as Class 9 Dangerous Goods, they demand specialized shipping practices, UN-approved protective packaging, and compliance with maritime transport regulations.
Our logistics team coordinates shipments directly from Chinese deep-water ports (such as Shenzhen, Shanghai, or Guangzhou) to Chittagong Port (Chattogram Port). We manage all necessary document declarations to help local custom clearance agents execute imports with minimized delay.

Detailed answers to key operational, custom, and performance questions regarding residential energy storage in Bangladesh.
LiFePO4 (LFP) is the safest lithium chemistry available for domestic battery storage. It boasts high thermal stability, a high thermal runaway threshold (up to 270°C), and handles high operational temperatures without degradation. LFP chemistry does not contain cobalt, eliminating risks of thermal runaway common in ternary NMC cells. For Chittagong's hot and humid environment, LFP offers a reliable and long-lasting storage option.
The ROI depends on local tariff rates, solar generation capacity, and backup requirements. Generally, a residential 10 kW hybrid solar system with energy storage in Chittagong offsets expensive grid consumption during peak-tariff windows. By replacing costly diesel generators (fuel costs, maintenance, noise, fumes) and optimizing self-consumption, typical systems achieve a full ROI payback within 4 to 6 years, with a designed system life exceeding 15 years.
Yes. Our premium hybrid systems support parallel battery operations and high transient surge currents. Our hybrid inverters are engineered to handle high startup inductive loads (such as water pumps, refrigerators, and multi-split air conditioners). By configuring multiple batteries in parallel, the combined continuous discharge current increases, ensuring these essential systems run uninterrupted during grid outages.
Our manufacturing processes follow ISO 9001, ISO 14001, and ISO 45001 frameworks. Every battery unit undergoes automatic end-of-line (EOL) functional testing, cycle testing, capacity sorting, and dynamic resistance testing. Our systems carry international certifications such as IEC 62619, CE, UN38.3 (for shipping safety), and UL 9540A, ensuring compliance with global and national regulatory standards.
We arrange sea freight from major Chinese ports directly to Chittagong Port (Chattogram Port). The average transit time from port-to-port ranges from 12 to 18 days. Production lead times vary depending on custom configurations but generally span 25 to 35 days. We provide comprehensive shipping documentation, including packing lists, commercial invoices, bill of lading, and UN38.3 certificates, to facilitate customs processing in Bangladesh.
