Common Questions Regarding Applicability in Different Countries/Regions
Qatar
Context: Qatar has invested heavily in infrastructure for mega-events and sustainability, with a focus on cooling, high reliability, and smart city integration.
Q1 - Reporter: Mr. Mohammed Al-Sada, The Peninsula - "For the stadium precincts built for the World Cup, how can this storage system contribute to operational efficiency now in their legacy use?"
A: These large venues have massive but often variable energy loads. The storage system can be used for daily peak shaving to reduce demand charges, provide backup power for critical operations, and potentially participate in grid services to generate revenue, turning the energy infrastructure into a continued asset.
Q2 - Reporter: Ms. Alya Al-Khater, Qatar Tribune - "Are the communication protocols compatible with the smart grid and IoT platforms being deployed in Lusail City and other smart districts?"
A: Yes. The use of standard industrial protocols like Modbus TCP/IP (over Ethernet) and CAN makes it straightforward to integrate our battery data into the centralized building and district energy management systems that are the backbone of smart cities like Lusail.
Q3 - Reporter: Mr. Hassan Al-Ansari, Gulf Times - "Given the high value of real estate, how compact is the footprint per kWh of storage?"
A: The unit's footprint is 0.187 m² (740x380mm). For a 16kWh unit, that's approximately 85.6 kWh per square meter of floor space. This high energy density is advantageous in settings where space, such as in central plant rooms, is at a premium.
Q4 - Reporter: Ms. Noor Al-Mannai, Al Raya - "What kind of training do you provide for facility management teams at major Qatari institutions?"
A: We provide comprehensive operational training covering system overview, normal operations, understanding alarm indicators, basic troubleshooting, and safety procedures. This empowers local teams to manage the system confidently day-to-day.
Q5 - Reporter: Mr. Peter Barker, Doha News - "How does the system perform in high-humidity conditions combined with heat, such as during the summer months?"
A: The specified operating range is 5-90% relative humidity, non-condensing. In Qatar's summer, where air conditioning is ubiquitous, the battery would be installed in a controlled indoor environment where humidity is managed, ensuring it operates well within its specified parameters.
Israel
Context: Israel is a tech innovator with a mature solar market, high electricity costs, advanced cybersecurity needs, and specific grid interconnection standards.
Q1 - Reporter: Ms. Talia Amar, Haaretz - "Israeli regulations require specific grid support functions for storage. Can this BMS provide frequency regulation and voltage control services?"
A: The battery's core capability--fast, accurate charge/discharge control--enables these services. The implementation is done through the system's PCS (Power Conversion System) or central controller. Our BMS provides the necessary real-time data and control interface to allow a qualified inverter or controller to execute grid-support functions as per Israeli Electricity Authority requirements.
Q2 - Reporter: Mr. Daniel Cohen, The Jerusalem Post - "How does the product address the cybersecurity requirements critical for Israeli critical infrastructure?"
A: We adopt a security-by-design approach. This includes secure boot, encrypted communications for remote access, role-based access control, and regular vulnerability assessments. We are prepared to work with Israeli security auditors to meet the specific standards required for critical infrastructure projects.
Q3 - Reporter: Ms. Shira Ben-David, Globes - "Is the system compatible with the prevalent single-phase inverters used in the Israeli residential market, or only three-phase?"
A: The battery outputs DC power and is agnostic to the inverter's AC phase configuration. It is fully compatible with both single-phase and three-phase hybrid inverters that operate within its voltage range and support the communication protocol.
Q4 - Reporter: Mr. Yoni Eshpar, Calcalist - "Can the system's software integrate with home automation platforms commonly used in Israel?"
A: Through its open communication protocols and our optional cloud API, third-party developers or home automation system integrators can access system data and send basic commands, enabling integration with popular smart home platforms for enhanced energy management scenarios.
Q5 - Reporter: Ms. Anat Rimon, Ynet - "What is the product's availability and lead time for the Israeli market?"
A: We have established a partnership with a leading Israeli distributor. Units are held in local stock for fast delivery, with typical lead times of 2-4 weeks for standard orders, ensuring quick deployment for residential and commercial projects.
South Africa
Context: South Africa faces an ongoing severe electricity crisis with daily "load-shedding" (rolling blackouts), leading to massive demand for reliable backup power solutions.
Q1 - Reporter: Ms. Thato Mokoena, Business Day - "During Stage 6 load-shedding, blackouts can last 4+ hours. How many units are needed to power a typical middle-class home's essentials throughout such an event?"
A: For essential loads (lights, fridge, Wi-Fi, TV, and a few plugs), a single 16kWh unit is typically sufficient for 8-12 hours, easily covering a 4-hour slot and providing buffer for extended outages. For homes with higher consumption, a second unit provides ample reserve.
Q2 - Reporter: Mr. Sipho Ndlovu, Mail & Guardian - "How does the total cost of ownership of this LiFePO4 system compare to a traditional lead-acid battery bank over 10 years?"
A: While the upfront cost of LiFePO4 is higher, its longer lifespan (10+ years vs. 3-5 for lead-acid), higher efficiency (95%+ vs. ~80%), zero maintenance, and ability to discharge deeply without damage result in a significantly lower total cost of ownership over a decade, making it the more economical choice.
Q3 - Reporter: Ms. Anja van Staden, Fin24 - "Can the system be configured to keep specific high-power appliances, like an electric geyser (water heater), running during an outage?"
A: Yes, but it requires careful system sizing. An electric geyser is a large load (~3-4kW). A 16kWh battery could run it for 4-5 hours, but this would deplete the battery quickly. The system can be configured to power it, but often users choose to selectively back up only essential circuits or use a solar geyser for greater efficiency.
Q4 - Reporter: Mr. Vusumuzi Mbele, News24 - "Are there any product liability or insurance considerations for homeowners installing this system?"
A: Our products are fully certified (IEC62619, CE) which is a baseline for insurance. We recommend homeowners inform their insurance provider of the installation. Many insurers in South Africa now view a solar-plus-storage system as a risk mitigator (preventing pipe bursts during outages, providing security lighting) rather than a liability.
Q5 - Reporter: Ms. Claire Bisseker, Sunday Times - "Is there a local after-sales service network for repairs and maintenance across South Africa's major cities?"
A: Yes, we have a growing network of accredited installers and service partners in Johannesburg, Cape Town, Durban, and Pretoria. They are trained to provide installation, commissioning, and warranty support, ensuring customers have local access to assistance.
