February 04, 2026
We installed an energy storage system for a supermarket in Samoa to reduce the supermarket’s energy consumption and provide it with a continuous supply of electricity, gradually realizing the goal of green energy.
Core of the project
Photovoltaic array---26.4kWp---Covering most of the supermarket's daytime electricity consumption
Inverter---30kW---High-efficiency conversion (>98.5%), supporting seamless switching between off-grid and on-grid
Energy storage system---30kWh (Li-Fe-Phosphate)--- Peak discharge + nighttime backup to ensure 24-hour operation of cold chain equipment
Three Transformative Values
1. Sharp reduction in energy costs
PV direct supply: daytime PV power generation to drive refrigerated cabinets, lighting and other high power-consuming equipment, reducing grid power purchases;
Peak-valley arbitrage: nighttime valley power storage, release at peak time；
Demand charge optimization: smoothing the electricity load, avoiding the peak penalty for electricity consumption, and then lowering the cost of the monthly average.
2. Zero interruption of electricity security
Off-grid supply protection: 30kWh energy storage instantly switches power supply during sudden power outage to support the operation of freezers and cashier systems；
Intelligent protection: three-level BMS safety monitoring (core-system-cloud) to eliminate the risk of overcharging/overheating.
3. Carbon Emission Reduction Visualization
Annual Carbon Reduction: 25.6 tons ≈ Planting 1400 pine trees.
