Burundi – A landmark residential project in Burundi has achieved complete energy independence through the implementation of Pytes' comprehensive energy storage system. This system not only addresses the challenges of unstable local grid power, ensuring a continuous and stable electricity supply for the household, but also provides a replicable and scalable technical model for energy autonomy in high-end residences.
The sophisticated energy ecosystem integrates three core components: a 100kWh Pytes energy storage battery bank, a set of three Deye hybrid inverters (totaling 32kW), and a 22kW rooftop solar array, working in perfect harmony to deliver uninterrupted power.This integrated approach — controlling generation, conversion, and storage — epitomizes the “full-stack” advantage, ensuring optimal performance and reliability.

Reliable Energy Storage: The Heart of the System
At the core of this installation lies the Pytes battery system, configured with 20 units of the E-Box 48100R models in parallel, delivering a substantial 100kWh storage capacity. Even during nights without solar input or consecutive cloudy days, it can support the continuous operation of all appliances in the mansion—including high-power air conditioners, water pumps, lighting, and office equipment—for over 24 hours.
The performance of the E-Box 48100R is equally exceptional. It utilizes inherently safe lithium iron phosphate technology, with a cycle life exceeding 6,000 cycles and an efficiency rate of over 95%. Paired with a self-developed BMS, it achieves precise charge and discharge management, real-time online monitoring and upgrades, and supports flexible expansion, ensuring long-term investment returns from both technical and lifespan perspectives.
Intelligent Energy Management: Seamless Power Quality

Pytes batteries boast excellent compatibility, having been adapted to over 20 mainstream inverter brands in the market. Among them, the collaborative solution with Deye inverters has been validated by numerous projects worldwide. This case once again selected this proven combination, providing strong assurance for the reliability of the entire energy system.
As the energy dispatch center of the system, the inverters deliver a total of 32kW of power, effortlessly handling the electricity demands of multiple high-power appliances, even when they start simultaneously. More importantly, it possesses intelligent energy management capabilities, enabling millisecond-level seamless switching between different power supply modes, prioritizing solar energy, and precisely managing battery charging and discharging. This not only ensures a continuous and stable household power supply with clean waveforms but also effectively protects sensitive precision appliances.
Solar Generation: Clean Energy Abundance

Notably, the system is equipped with a 22kW solar array, consisting of 40 high-efficiency 550W photovoltaic panels. On days with ample sunlight, the average daily electricity generation can reach approximately 100 kWh. This not only fully meets all daytime power demands but also consistently channels surplus green energy into the storage system, truly achieving a virtuous energy cycle of "daytime generation and surplus storage."

From system design to operational deployment, the project team conducted rigorous research and component selection to ensure efficient collaboration among all units. The success of this case is reflected not only in the fundamental aspect of "stable electricity supply" but also extends to multiple enhancements in economy, environmental protection, and quality of life:
l Ultimate Electricity Experience: Users have completely bid farewell to frequent power outages and voltage instability. The system operates quietly with zero emissions, supporting 24/7 uninterrupted high-quality power supply, meeting the needs of daily living, work, and high-end entertainment.
l Significant Economic Benefits: By maximizing the use of free solar energy, household electricity expenses are substantially reduced. Combined with local peak and off-peak pricing mechanisms, the system offers a considerable return on investment. With a design lifespan of up to 20 years, it ensures long-term and stable energy-saving benefits.
l Technological Demonstration Effect: This case provides a highly reliable, technologically mature, and scalable model of energy autonomy for high-end residences and commercial facilities in Burundi and other regions with weak power infrastructure. It demonstrates that high standards of energy independence can be achieved through appropriate green energy technologies, thereby enhancing the quality of life and productivity.
l Reduced Carbon Footprint: By utilizing renewable energy for power generation, carbon emissions are significantly reduced, contributing tangibly to global sustainable development. This not only establishes the homeowner as a "pioneer in environmental protection" but also makes the residence a local exemplar of green living.

From solar collection and intelligent dispatch to reliable storage, Pytes' full-stack solution has built a resilient, efficient, and clean household microgrid. This successful case provides a trustworthy model of energy autonomy for Burundi and similar regions, further strengthening our determination to collaborate with global partners and to jointly stride toward energy independence and a low-carbon future.
Pytes — power a better life!
