Common Questions Regarding Applicability in Different Countries/Regions
Cambodia

Cambodia is rapidly developing, with a focus on rural electrification, garment manufacturing, and affordable renewable energy solutions.

Q1 - Reporter: Mr. Sok Vichea, Phnom Penh Post
"For a small garment workshop, can this system provide enough backup to finish an order during a sudden power cut?"

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.

Q2 - Reporter: Ms. Keo Sreymom, Khmer Times
"Are there any government subsidies or financing partnerships available to make this technology more accessible to Cambodian SMEs?"

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.

Q3 - Reporter: Mr. Heng Sopheaktra, Cambodia Daily
"How simple is the daily operation for a business owner with limited technical knowledge?"

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.

Q4 - Reporter: Ms. Pisey Chan, The Post
"Can the batteries be recycled at end-of-life, and is there a plan for a take-back program in Cambodia?"

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.

Q5 - Reporter: Mr. Samnang Chea, VOD
"What are the key differences between your 'self-developed' cells and cheaper alternatives on the market?"

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.

United Arab Emirates

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.

Q1 - Reporter: Mr. Youssef Al Mehairi, The National
"In the UAE's summer, ambient temperatures in shaded areas can exceed 50°C. How does the system's derating at 40-50°C impact its ability to provide critical backup for air conditioning?"

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.

Q2 - Reporter: Ms. Noora Al Marzooqi, Gulf News
"Does the system have any specific certifications required for connection to the DEWA (Dubai Electricity and Water Authority) grid or for projects seeking LEED certification?"

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.

Q3 - Reporter: Mr. Arjun Nair, Khaleej Times
"For a large villa with a swimming pool pump, chiller, and extensive lighting, how many units are typically required?"

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.

Q4 - Reporter: Ms. Fatima Al Bloushi, Emirates 24/7
"How does the 'remote firmware upgrade' function work in practice, and does it require user intervention?"

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.

Q5 - Reporter: Mr. James Henderson, Dubai Eye
"Is there a local stock of units and parts in the UAE to support the fast-paced construction and project timelines here?"

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

Saudi Arabia's Vision 2030 drives renewable energy adoption, industrial diversification, and has a harsh desert environment with sand and dust.

Q1 - Reporter: Mr. Khalid Al-Omran, Arab News
"How does the IP20 enclosure protect against the fine, abrasive sand (subsilt) common in the Saudi desert?"

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.

Q2 - Reporter: Ms. Lulwah Al-Fozan, Saudi Gazette
"Can this storage system help a commercial entity comply with the Saudi Energy Efficiency Program's requirements?"

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.

Q3 - Reporter: Mr. Sultan Al-Qahtani, Al Riyadh
"For the massive giga-projects like NEOM, is this scalable architecture suitable for district-level energy storage?"

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.

Q4 - Reporter: Ms. Nouf Al-Rashid, Asharq Al-Awsat
"What is the expected calendar life, not just cycle life, of the battery in the dry, hot Saudi climate?"

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.

Q5 - Reporter: Mr. Faisal Al-Tamimi, Al Eqtisadiah
"Does First Tech have plans for local assembly or joint ventures under Saudi Arabia's localization (Saudization) programs?"

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.
