Project Background

In recent years, Ecuador has been facing an ongoing energy crisis, with frequent grid instability and unexpected power outages affecting both industrial production and daily life.

Against this backdrop, solar energy has rapidly emerged as a reliable alternative, creating new opportunities for local businesses and installers.

Issac, a local entrepreneur, recognized this shift early and began exploring the solar industry nearly two years ago. With a sharp understanding of the huge market potential and the urgent local demand for stable power supply, he made a strategic decision to invest in solar energy solutions—both for his own manufacturing factory and to scale up his solar installation business to serve more local customers.

Client Demands

Issac’s primary objective was to secure a stable and uninterrupted power supply for his factory while reducing dependence on the unstable national grid. At the same time, he aimed to expand his solar business by providing customized small-scale residential systems for local homeowners.

Key requirements included:

1. A reliable high-voltage energy storage system (ESS) tailored for industrial use
2. Proven, high-quality products that are adaptable to emerging markets
3. Sustained technical support for long-term installation and project operation

United Energy Solution

For the factory, United Energy provided an integrated 50kW high-voltage PV + energy storage solution, which is capable of generating up to 125kWh of electricity per day. The system uses solar energy to power daytime loads and charge storage, ensuring reliable power at night or on cloudy days. This ensures uninterrupted operation during grid outages, maximizes solar self-consumption, and reduces peak electricity costs.

System Configuration:

1、PV Capacity: 50kW

16 × 630W PV modules per string

5 strings in total (80 PV modules in full)

2、Inverter Capacity: 50kW

Wide DC input voltage range: 160–800V, adaptable to varying solar irradiance conditions

3、High-Voltage Battery Storage: 102.4kWh

2 independent battery clusters (512V / 100Ah, 51.2kWh per cluster)

Each cluster comprises 10 high-voltage battery modules (5.12kWh per module)

Each module integrates 16 high-performance LFP cells (3.2V / 100Ah)

A dedicated HV control box for each cluster, ensuring comprehensive system safety and stable real-time communication

For the residential solar market, the United Energy team provided complete turnkey kits of 5kW and 8kW off-grid solar systems, paired with 5kWh and 10kWh energy storage respectively. This standardized yet flexible configuration enables Issac to easily replicate and deploy the systems for local homeowners, accelerating his market expansion in Ecuador and helping local households achieve greater energy independence and substantial electricity cost savings.

Looking Ahead & Conclusion

Issac’s project demonstrates how reliable solar and energy storage solutions can transform energy challenges into business opportunities.

By securing stable power for his own manufacturing facility while simultaneously expanding residential installations, Issac has built a practical and scalable solar business model. The factory system not only improves operational resilience but also serves as a trusted reference site for local customers.

As Ecuador continues to face grid instability, distributed solar and storage are becoming essential infrastructure rather than optional upgrades. Projects like this highlight the growing role of local partners in accelerating the energy transition.

United Energy remains committed to supporting installers and distributors with dependable products, technical guidance, and scalable system designs that perform in real-world conditions.

Together with us, deliver cleaner, more reliable energy solutions — empowering businesses, supporting communities, and driving sustainable growth across emerging markets.
