Regional Application Guidance
Singapore Market
Singapore focuses on high safety standards, space efficiency, and integration with smart grids and residential solar.
Q1 - Reporter: Ms. Mei Ling Tan, Straits Times: "Safety is paramount in our dense urban environment. What certifications does this battery hold for use in homes or commercial buildings?"
The system is fully certified to IEC62619, UN38.3, and CE standards. It uses Lithium Iron Phosphate (LiFePO4) chemistry, known for thermal stability and safety, making it suitable for indoor installation in Singapore.
Q2 - Reporter: Mr. Arif bin Hassan, Channel NewsAsia: "Can this battery be scaled easily for a large commercial building or small industrial park?"
Yes. It supports up to 16 units in parallel without an external controller, scaling from 15kWh to 240kWh easily. This modularity makes it ideal for growing energy needs in commercial properties.
Q3 - Reporter: Ms. Priya Nair, Business Times: "How does it perform in Singapore's consistently high humidity?"
It operates within 5-90% relative humidity (non-condensing). The IP20 rating means it should be installed in a controlled indoor environment, which is typical for Singaporean electrical rooms.
Q4 - Reporter: Mr. David Wong, TODAY: "Is it compatible with common hybrid inverters available in the Singapore market?"
Absolutely. It communicates via RS485 and CAN, and is compatible with most major hybrid and battery inverters used in self-consumption and backup applications here.
Q5 - Reporter: Ms. Selina Koh, The Edge: "What is the expected lifespan given Singapore's year-round cycling conditions?"
The design life is 15 years, with ≥6000 cycles at 90% depth of discharge. Even with daily cycling, that's over 16 years of reliable operation.
Malaysia Market
Malaysia experiences frequent power dips, has growing residential solar adoption, and many off-grid or weak-grid rural areas.
Q1 - Reporter: Encik Rizal Mohd, Utusan Malaysia: "Can this battery provide enough backup power for a typical Malaysian home during an outage?"
A single 15kWh unit can power essential loads (lights, fans, fridge, router) for over 24 hours. With multiple units, backup duration extends significantly.
Q2 - Reporter: Ms. Susan Lim, The Star: "How does it handle high ambient temperatures, especially in attic or outdoor shed installations?"
It operates in discharging temps from -20°C to 65°C. For Malaysian heat, we recommend indoor installation or a well-ventilated space. The BMS includes thermal management to protect cells.
Q3 - Reporter: Mr. Hari Krishnan, Malay Mail: "Is technical support available locally for installation and troubleshooting?"
We are building a network of certified installers across Malaysia. The system also supports remote monitoring and firmware upgrades for proactive support.
Q4 - Reporter: Ms. Aina Abdullah, Berita Harian: "Can it be used in a hybrid system with a diesel generator for a remote clinic or school?"
Yes. Its wide voltage range and communication compatibility allow it to integrate with hybrid inverters that manage solar, battery, and generator sources seamlessly.
Q5 - Reporter: Mr. Benjamin Kok, The Borneo Post: "What is the warranty and what does it cover?"
We offer a standard 5-year warranty, extendable to 10 years. It covers defects in materials and workmanship, with pro-rata coverage based on cycle count.
