Battery Chemistry: Almost certainly Lithium Iron Phosphate (LiFePO4). This chemistry is preferred for home energy storage due to its long cycle life, high safety profile, thermal stability, and consistent performance – crucial factors for the Nigerian climate.
Likely Voltage: 48V (nominal), as this is the standard for modern hybrid inverter compatibility.
Likely Capacity Range: Based on their size and common residential needs, these units probably come in capacities ranging from 5kWh to 15kWh per module.
- For EL SALI: This capacity range is ideal for daily backup during outages, or for storing solar energy to be used during the night.
Scalability: Most modern ESS batteries are modular, meaning multiple units can be connected in parallel to increase the total storage capacity to meet higher energy demands.
Built-in Battery Management System (BMS): Essential for protecting the battery from overcharging, over-discharging, over-current, and extreme temperatures, ensuring safety and longevity.
Cycle Life: Expect a long cycle life, typically 6,000+ cycles at 80% Depth of Discharge (DoD), translating to 15+ years of daily use.

Great things are on the horizon
