Solar Energy Storage Project in Sudan with 150A MPPT 11kW Battery Inverter and 16kWh LiFePO4

In Sudan, electricity supply has long been unstable. Frequent power outages affect not only daily household life but also small businesses and even agricultural irrigation. To solve this problem, we installed a solar energy storage system in Sudan. The project included 1 Axpert MAX TWIN inverter and 2 M90 PRO batteries.

Why This System?

• Axpert MAX TWIN Inverter: A high-performance off-grid inverter with a 150A MPPT solar charger, dual outputs for smart load management, and Wi-Fi monitoring via mobile app.
• M90 PRO Battery: Each unit provides 16.384kWh capacity. Two units offer more than 32kWh of storage. With ≥8000 cycles at 80% DOD, it supports high current charge/discharge and comes with intelligent BMS protection.

This setup is perfect for home use or small shops that need stable power.

Installation Process: From Design to Operation

Step 1: Site Survey and System Design

Before installation, we carried out a site survey to check roof direction, sunlight hours, and energy demand. Sudan has excellent solar resources, with average solar radiation of 5.5–6.0 kWh/m² per day, making it ideal for solar energy systems.

We designed the system with 1 inverter and 2 batteries. The inverter was placed indoors with good ventilation, while the batteries were installed side by side against the wall for easy maintenance.

Step 2: Inverter Installation

• Mount the inverter on the wall with proper ventilation and dust protection.
• Connect the PV input cables (90VDC–450VDC supported for flexible solar layout).
• Link to grid power or a backup generator for continuous supply during cloudy days.
• Configure the LED indicator and Wi-Fi module. Users can monitor the system via smartphone app.

Step 3: Battery Installation

• Two M90 PRO batteries were connected in parallel, giving a total storage capacity of 32.7kWh.
• RS485 ports were used to connect batteries with the inverter for communication.
• The built-in BMS ensures safety by preventing overcharge and over-discharge.
• Each battery weighs 126.6kg, so lifting tools were required for placement, with space left for cooling.

Step 4: System Testing and Setup

• Programmed the solar inverter to discharge batteries at night and charge during the day.
• Tested discharge current up to 200A to match inverter output.
• Checked RGB lights and mobile monitoring to confirm smooth operation.

System Performance

• Daily Power Supply: Solar energy during the day, batteries at night, ensuring 24/7 electricity.
• Cost Savings: Compared with diesel generators, energy costs were reduced by 40%–60%.
• Eco-Friendly: The system reduces annual carbon emissions by around 10 tons of CO₂.

Why Energy Storage is Important for Sudan

According to the International Energy Agency (IEA), about 40% of Sudan’s population lacks stable electricity. Solar + storage solutions not only improve household power supply but also support agriculture and small businesses, helping local economic growth.

Conclusion

This case study shows how a small but efficient solar energy storage system can be installed in Sudan. From design to installation and testing, every step ensured stability and safety. Projects like this will help more families and communities achieve energy independence, reducing reliance on fossil fuels.
