217KWH-50KW Hybrid ESS Solution
Myanmar Jinding Gas Station — Hybrid Solar + Storage Project
This project delivers a 217 kWh / 50 kW hybrid energy storage system (ESS) installed at the Jinding Gas Station in Myanmar. The system operates in hybrid mode, integrating grid power with rooftop solar photovoltaic (PV) generation to create a self-sustaining microgrid that charges during daylight hours and discharges at night to power station operations.
The solution centers on a compact cabinet-type all-in-one unit featuring an air-cooled lithium iron phosphate (LFP) battery pack (216S / 314Ah cells, 691.2V nominal) paired with a hybrid PCS/inverter that supports both AC grid connection and DC solar MPPT input (up to 850V). During daytime, excess solar generation charges the battery while simultaneously supplying station loads through the grid; at night, the stored energy is discharged to cover lighting, fuel pumps, and convenience store operations — dramatically reducing diesel generator dependency and electricity costs.

🔌 Key Innovation: Compact Hybrid Cabinet ESS for Off-Grid Edge Sites
This solution packs 217kWh of air-cooled LFP storage plus a 50kW hybrid PCS into a single 1350×1350×2200mm cabinet — small enough to fit against the exterior wall of a gas station building without requiring a dedicated battery room or container pad. The hybrid inverter accepts both 400V AC grid input and up to 1000V DC solar PV input via built-in MPPT controllers (250–850V operating range), enabling true island-capable operation. With cycle life exceeding 8000 cycles at 80% DOD and a total weight of only 1.9 tonnes, this system represents the ideal balance of power density, deployment simplicity, and total cost of ownership for remote commercial sites with unreliable grid access.
- Air-Cooled LFP Battery Pack: 216S configuration using 3.2V / 314Ah prismatic LFP cells (217 kWh total, 691.2V nominal). Air cooling eliminates liquid coolant maintenance overhead. Cycle life ≥8000 cycles @ 80% DOD. Operating temperature range -25°C to 55°C.
- Hybrid PCS/Inverter: 50kW rated / 55kW peak output supporting simultaneous grid-tied operation and solar MPPT charging. Maximum PV input voltage 1000V, MPPT range 250–850V. Four-quadrant control, power factor adjustable.
- Solar + Grid Hybrid Operation: Rooftop PV array charges the ESS during daylight hours via built-in MPPT controllers. The system intelligently manages three power sources — solar, battery, and grid — prioritizing solar self-consumption first, then battery discharge, with grid as backup only.
- Nighttime Autonomous Supply: After sunset, the fully-charged 217kWh battery powers all station loads including fuel pump motors, LED lighting, POS systems, and refrigeration — eliminating or drastically reducing nighttime grid/diesel dependency.
- Compact Cabinet Deployment: Single-cabinet design (1350×1350×2200mm, 1.9T) installs directly against the building exterior wall on a simple concrete plinth. No dedicated battery house, no container foundation, minimal civil works.
- Integrated BMS Safety: Multi-level Battery Management System with over/under voltage, current, and temperature protection. IP54 enclosure rating suitable for outdoor installation. Remote monitoring via TAOYAN EMS platform.
