Common Questions Regarding the Applicability of Battery Packs in Different Countries/Regions
Thailand

Context: High solar adoption, demand for residential and SME backup, and hot climate.

Q1 - Reporter: Khun Chatchai Somsak, Bangkok Post - "How does the battery perform in Thailand's hot season when temperatures exceed 40°C?"
A: It can discharge up to 65°C. Between 40-50°C, derating may occur, but the BMS will manage temperature to ensure safety and longevity.
Q2 - Reporter: Khun Anongnat P., The Nation - "Can it be used for a small restaurant or shop to reduce peak demand charges?"
A: Absolutely. When paired with a suitable inverter, it can discharge during peak hours to shave grid demand, lowering electricity bills significantly.
Q3 - Reporter: Khun Sirinapa W., Thai Rath - "Is there a Thai-language app for monitoring?"
A: Our monitoring platform supports multiple languages, including Thai, for easy access to system data, history, and alerts.
Q4 - Reporter: Mr. Thomas Beagle, The Phuket News - "For villa resorts with multiple villas, can one large battery bank serve several units?"
A: With parallel capability up to 16 units, you can create a central storage system to support multiple villas or facilities within a resort.
Q5 - Reporter: Ms. Panida S., Matichon - "What maintenance is required?"
A: It's essentially maintenance-free. Regular visual inspection and ensuring ventilation are recommended. The BMS handles cell balancing automatically.
Vietnam

Context: Rapid growth in rooftop solar, high electricity costs for SMEs, and frequent power fluctuations.

Q1 - Reporter: Ms. Nguyen Thi Hoa, VnExpress - "Can this battery help a small factory avoid production downtime during grid fluctuations?"
A: Yes. Its response time is instantaneous when paired with an inverter. It can provide seamless backup during grid dips or outages, keeping production running.
Q2 - Reporter: Mr. Tran Van Duc, Tuoi Tre - "What is the recommended charge current for fastest charging without harming the battery?"
A: The recommended charge current is <150A, which allows a full charge in about 2-3 hours from empty, depending on solar or grid input.
Q3 - Reporter: Ms. Le Mai Lan, Vietnam News - "Is it safe to install near living areas given lithium battery concerns?"
A: LiFePO4 is the safest lithium chemistry. It does not combust under misuse. The battery enclosure is robust and includes protection against short circuit and overcurrent.
Q4 - Reporter: Mr. Pham Quang Huy, Thanh Nien - "Can it be charged from both solar and grid simultaneously?"
A: That functionality depends on the inverter. The battery itself accepts charge from any DC source within its voltage and current limits.
Q5 - Reporter: Ms. Hoang Thi Minh, Sai Gon Giai Phong - "How does the warranty handle capacity degradation?"
A: The warranty guarantees that the battery will retain a certain percentage of its original capacity over the warranty period, subject to cycle count and usage conditions.
