Cambodia is rapidly developing, with a focus on rural electrification, garment manufacturing, and affordable renewable energy solutions.
A: Yes. A single 16kWh unit can power essential sewing machines, lights, and fans for several hours. This allows a workshop to complete work in progress, protect fabric from damage in unfinished processes, and meet delivery deadlines despite grid instability.
A: We are actively engaging with development banks, microfinance institutions (MFIs), and local banks in Cambodia to create tailored financing products, including equipment leasing and low-interest loans, to help SMEs adopt solar-plus-storage solutions.
A: The system is designed to be fully automatic. Once installed and configured by a certified technician, it requires no daily intervention from the user. The owner can monitor simple status indicators (like state of charge) if desired, but the system runs autonomously.
A: LiFePO4 batteries are highly recyclable. We are committed to responsible product stewardship and are working to establish a regional take-back and recycling partnership to serve the Cambodian market, ensuring materials are recovered and disposed of properly.
A: Our vertical integration--from cell to pack--allows us to enforce strict quality control at every stage. Our self-developed cells use high-grade materials and manufacturing processes to ensure consistency, energy density, and cycle life that often exceeds generic cells, providing better long-term value and reliability.
The UAE features an extreme desert climate, ambitious renewable energy targets (like Dubai's Clean Energy Strategy 2050), and a high standard for luxury and commercial projects.
A: The derating is a protective feature to extend battery life. While maximum continuous current may be reduced slightly above 40°C, the system is still fully operational. For critical AC backup, proper system sizing from the outset accounts for local temperature profiles to ensure sufficient capacity is always available, even during derating conditions.
A: The system holds CE and IEC62619 certifications, which are key international benchmarks. For direct grid interconnection in the UAE, the inverter must comply with local standards like DEWA's regulations. Our batteries are compatible with inverters that carry these local certifications, and the system's sustainability attributes contribute to LEED points for energy storage and renewable energy integration.
A: A detailed energy audit is best. However, as a rough estimate, a high-consumption villa might need 32-48kWh of storage (2-3 units) to meaningfully shift evening loads and provide 4-6 hours of backup for essential circuits, including the pool pump for limited periods.
A: Updates are pushed securely to the system's gateway. For minor updates, they can often be installed automatically during low-activity periods. For major updates, a notification is sent to the installer or user, who can schedule the update at a convenient time. The process is designed to be simple and non-disruptive.
A: Yes, we maintain strategic inventory in Jebel Ali to serve the UAE and GCC region. This allows us to support project timelines and provide rapid replacement parts if ever required, aligning with the market's expectation for swift execution.
Saudi Arabia's Vision 2030 drives renewable energy adoption, industrial diversification, and has a harsh desert environment with sand and dust.
A: IP20 protects against solid objects larger than 12.5mm, not fine sand. For Saudi conditions, we mandate installation within a protected environment--such as a dedicated, sealed electrical room or an IP54-or-higher external cabinet with dust filters. This is critical for long-term reliability and is part of our installation guidelines for the region.
A: Absolutely. By reducing peak grid demand and enabling greater use of on-site solar, the system directly improves a facility's energy intensity metrics. The data from our monitoring platform can be used to document these improvements for compliance reporting under the Saudi Energy Efficiency Center (SEEC) programs.
A: The modular architecture is ideal for scalable deployment. While a single cabinet scales to 256kWh (16 units), multiple such clusters can be managed together to form MWh-scale storage plants. Our systems can be integrated into the smart grid controllers envisioned for futuristic projects like NEOM.
A: LiFePO4 chemistry offers excellent calendar life. With proper thermal management (installation in a controlled environment), we expect the battery to retain a significant portion of its capacity for 12-15 years, even in Saudi's climate, independent of how often it is cycled.
A: We are actively exploring partnerships for local value-add activities, such as final assembly, integration, and testing, in alignment with Vision 2030's goals for industrial localization and technology transfer.
