Project: 24kW/60kWh Residential Energy Storage System
Location: Lagos, Nigeria
Product composition:
Demuda customized 750W solar panels × 32 pcs
Demuda customized 12kW inverter × 2 units
Demuda customized 15kWh battery × 4 units
This project was installed in Lagos, Nigeria, where unstable grid supply, frequent power outages, and high diesel generator costs have long been a headache for many households. Demuda provided a customized all-in-one residential solar-plus-storage solution integrating PV generation, backup power, and intelligent control — successfully solving daily power needs and significantly reducing electricity costs.
The system uses 32 high-efficiency solar panels to make full use of Lagos's abundant sunlight. During the day, PV power supplies household loads first while charging the 60kWh battery pack. Two 12kW inverters run in parallel, providing ample load capacity to power various household appliances. When a grid outage occurs, the system automatically switches to battery power within milliseconds, keeping critical loads running. Homeowners no longer worry about blackouts and say goodbye to the noise, fumes, and high maintenance costs of diesel generators.
Product core advantages (case-verified):
1. Off-grid backup with seamless outage switchover
The system supports both on-grid and off-grid operation. When a grid outage happens, the inverter automatically transfers to battery power in milliseconds. Key loads such as lighting, refrigerators, fans, and communication devices continue running without interruption.
2. PV self-consumption and lower electricity costs
Under Lagos‘s strong sunlight conditions, the solar panels generate a considerable amount of electricity daily. Power is first used for household loads, with surplus energy stored in the batteries for nighttime or power outages. This greatly reduces reliance on the grid and diesel generators, resulting in a significant drop in monthly electricity expenses.
3. Large capacity, long backup time, suitable for typical household loads
The 60kWh battery pack combined with two 12kW inverters can easily power multiple air conditioners, refrigerators, pumps, lighting, and electronic devices in a typical Lagos household. The backup duration is sufficient to meet round-the-clock power needs.
For households in Lagos and other power-deficient regions across Africa, Demuda offers residential and small-to-medium solar-storage solutions ranging from 5kWh to 50kWh+, with customized features such as diesel generator integration, remote monitoring, and capacity expansion — meeting the personalized needs of different customers in different regions.
