SOSEN 60kW Hybrid Inverter for C&I Energy Storage in Myanmar

Power reliability remains a major challenge for many commercial and industrial facilities in Myanmar. Limited grid availability, voltage fluctuations, and frequent outages can disrupt production and increase dependence on diesel generators. For factories with continuous production, an unexpected power interruption can lead to equipment downtime, production losses, and delayed orders. At the same time, rising fuel costs make diesel backup increasingly expensive to operate.

To address these challenges, SOSEN and its local partner CTE have deployed 60kW hybrid inverter solutions for several commercial and industrial owners in Myanmar, including office complexes, garment factories, and textile plants. These projects combine solar, battery storage, grid, and diesel generation to provide a more stable and flexible power supply.

Commercial Complex ESS

A mixed-use commercial complex in Yangon includes a bank and an office building, each with different load profiles and power requirements. The bank is equipped with a 180kW / 360kWh energy storage system, while the office building uses a 240kW / 480kWh system. Seven sets of SOSEN 60kW hybrid solar inverters are deployed across two independent parallel systems.

The two buildings experience similar daytime peak periods but have different load levels. The independent parallel configuration allows each system to be managed according to its own power demand. This modular design also provides room for future expansion. When additional solar or battery capacity is required, and the site's electrical infrastructure allows, more inverters can be added without extensive system modifications.

Myanmar Garment Factory ESS

For garment manufacturing, stable electricity is essential. Equipment such as sewing machines and cutting systems can be affected by sudden outages, leading to production interruptions and order delays. In Yangon, the grid voltage can fluctuate between 180V and 264V, alongside frequent outages and switching between grid and diesel generation. Before the energy storage system was installed, diesel-related costs accounted for up to 40% of the factory's total operating costs. The factory deployed eight sets of SOSEN 60kW hybrid inverters, together with an 800kWh battery system.

The system supports a wide 135V–850V battery voltage range, helping it operate across demanding grid conditions. Its high overload capability also supports inductive loads with high starting currents, such as sewing motors and air compressors. The 480kW inverter capacity is higher than the factory's typical 380kW full-load demand, providing additional capacity for future load growth and expansion.

After commissioning, the factory reported significantly improved production stability, with unexpected power outages largely no longer causing production interruptions. Energy and equipment maintenance costs were also reduced by approximately 40%–50%.

Myanmar Textile Factory ESS

Textile production typically requires higher and more continuous power demand. Processes such as spinning and weaving are particularly sensitive to power interruptions. For this project, the factory installed six sets of SOSEN 60kW hybrid inverters, paired with a 1,140kWh battery system.

The inverters can operate in parallel while handling nonlinear and high-impact loads from the production line. Each inverter also features two independent battery interfaces, with a total charge and discharge current of up to 200A, providing sufficient battery power for continuous operation.

One Hybrid Inverter Platform for Diverse C&I Applications

These projects demonstrate how a properly configured commercial and industrial energy storage system can address different power requirements in Myanmar. From commercial buildings to garment and textile factories, SOSEN 29.9–60kW hybrid inverters provide key capabilities for demanding C&I applications:

• Wide battery voltage range for greater system compatibility
• High charge and discharge current to support demanding loads
• Parallel operation for flexible system sizing and expansion
• High PV input capability for efficient solar utilization
• Flexible solar, battery, grid, and diesel integration for more reliable power management

Combined with CTE's local project resources, SOSEN can develop energy storage solutions based on actual load profiles and site conditions, helping businesses reduce diesel dependence and build a more stable and cost-efficient power system.
