Common Questions Answered by Different Countries/Regions
Japan
Kenji Tanaka, Japan Tech Daily
How does the inverter ensure stability during frequent grid fluctuations and outages?
The EM Series features a fast transfer time of 10ms for computers and 20ms for appliances, ensuring seamless switching between grid, solar, and battery. Its pure sine wave output protects sensitive electronics.
Is it compatible with Japanese grid standards (100V, 50Hz)?
The inverter outputs 220-230V AC. For 100V systems, an additional transformer is recommended. Frequency auto-senses 50/60Hz.
Can it work with Japanese-brand lithium batteries?
Yes, via RS485 communication. It supports BMS protocols for safe and efficient battery management.
What is the expected lifespan in high-humidity environments?
With a detachable dust cover and humidity tolerance of 5-95% non-condensing, it is suitable for humid regions like coastal Japan.
Does it support remote monitoring in areas with poor internet?
WiFi is optional. For low-connectivity areas, RS232/RS485 allows local monitoring and configuration.
South Korea
Ji-hyun Park, Korea Energy News
Can the inverter be integrated with home energy management systems?
Yes, through RS485 communication, it can connect with smart home systems for real-time monitoring and control.
What is the efficiency when using both PV and AC charging simultaneously?
Peak efficiency from PV to AC is 96%, and battery to AC is 93%. Combined charging is managed intelligently to maximize efficiency.
Is there surge protection for high-power appliances?
Yes, surge power ratings range from 3000VA to 12400VA depending on model, supporting motor starts and high inrush loads.
How does the EQ function extend battery life?
The Equalization function optimizes charging cycles, prevents sulfation, and balances cell voltages, extending battery lifespan.
Can it operate without a battery in solar-only mode?
Yes, No-Battery Mode allows direct PV-to-AC conversion, ideal for daylight-only applications.
India
Arjun Mehta, India Solar Times
What is the maximum PV array power supported?
From 2000W for the 1.5KW model up to 6500W for the 6.2KW model, allowing flexible system sizing.
Can it handle voltage fluctuations common in Indian grids?
Acceptable input range is 90-280V AC, suitable for wide grid variations.
Is it compatible with Indian lithium battery brands?
Yes, through RS485 BMS communication, it works with most lithium batteries including LiFePO4.
What cooling mechanism is used for hot climates?
Passive cooling with vented design, operating up to 50°C. Detachable dust cover helps in dusty environments.
What is the warranty and service network in India?
We offer a standard 2-year warranty with extended options. Service partners are available in major cities.
