FAQs from Different Countries
1. Indonesia (Southeast Asia)
Q1: Is the EM Series inverter suitable for the high humidity and frequent rain in Indonesia?
A1: Absolutely. The EM Series inverters are built with a detachable dust cover and are designed to operate in 5% to 95% relative humidity (non-condensing), making them highly resilient against Indonesia's tropical climate, ensuring reliable performance in coastal and rural areas.
Q2: Can this system power my entire home during a frequent local power outage (mati lampu)?
A2: Yes. With models ranging from 1.5KW to 6.2KW and multiple output priorities (UTL, SOL, SBU), you can configure the inverter to seamlessly provide backup power from solar and batteries during outages, keeping your essential appliances and even personal computers running without interruption.
Q3: How does the Lithium Battery activation by PV benefit me in remote Indonesian islands with unstable grid power?
A3: This feature is crucial for remote locations. If your lithium battery is completely drained, the inverter can use solar power alone to reactivate it. You don't need a stable grid connection, making it a perfect, self-sustaining power solution for islands and villages.
Q4: With varying sunlight in the archipelago, how efficient is the solar charging?
A4: The built-in MPPT charger is highly efficient, with a peak efficiency of 96% from PV to inverter. Its wide MPPT voltage range (60V-500V) ensures it captures and converts even low or fluctuating sunlight into usable power, maximizing your solar harvest throughout the day.
Q5: Is it compatible with the lithium batteries available in the local market?
A5: Yes. The inverter features RS485 communication specifically for compatible work with LiFePO4 batteries, a popular and safe choice. This ensures optimal charging, extends battery life, and provides accurate status monitoring, giving you peace of mind with locally sourced components.
Q6: Can I monitor my system's performance from my phone in Jakarta while my family uses it in Bali?
A6: Yes, with the optional WiFi module. You can remotely monitor your system's performance, energy production, and consumption in real-time from anywhere, allowing you to manage your family's power usage and savings efficiently.
2. Philippines (Southeast Asia)
Q1: How does the EM inverter handle the frequent typhoons and power fluctuations in the Philippines?
A1: The inverter features a very fast transfer time (10ms for personal computers) and an acceptable voltage range as wide as 90-280VAC for home appliances. This protects your sensitive electronics from damage caused by brownouts and rapid voltage changes common during storms.
Q2: I have limited roof space. Can I still get a powerful system?
A2: Certainly. The high PV input voltage (up to 500VDC) allows you to use fewer, higher-efficiency solar panels to achieve the desired power (e.g., up to 6500W with the EM6200 model), making it ideal for urban homes in Manila with space constraints.
Q3: Is it true this inverter can work without a battery? How does that help me save money?
A3: Yes, the "No Battery Mode" is a key feature. It allows the inverter to directly power your loads from solar panels during the day. This eliminates the initial cost of batteries, making solar power adoption more affordable while still significantly reducing your daytime electricity bills from the grid.
Q4: We have high temperatures year-round. Will the inverter overheat?
A4: The EM Series is designed to operate reliably in temperatures up to 50°C (122°F). Its high efficiency (up to 96%) also means less energy is wasted as heat, ensuring stable performance even during the hottest days in the Philippines.
Q5: Can I use this for a small business, like a sari-sari store, to run freezers and lights?
A5: Absolutely. The pure sine wave output ensures that sensitive equipment like freezers and LED lights run smoothly and efficiently. Models like the EM3500-24L (3.5KW) with a 7000VA surge can easily handle the startup power demands of refrigeration units.
Q6: What support is available for installation and maintenance locally?
A6: While we recommend certified installers, the inverter's design is user-friendly. The RS232/RS485 ports facilitate easy diagnostics. We are building a network of local partners to provide installation support and service, ensuring you have reliable assistance.
3. Vietnam (Southeast Asia)
Q1: How can the EM inverter help me combat rising electricity prices (EVN) in Vietnam?
A1: By maximizing solar self-consumption, the EM inverter drastically reduces your reliance on the grid. Its high-efficiency MPPT and multiple charging sources (PV + AC) ensure you use the cheapest power available, leading to substantial long-term savings on your electricity bills.
Q2: Is the system compatible with the 220V/50Hz standard used in Vietnam?
A2: Yes, the output is specifically 220/230VAC ±5% at 50/60Hz (auto-sensing), making it perfectly compatible with all Vietnamese home appliances and electrical standards without requiring any additional converters.
Q3: My area has dust and pollution. How is the inverter protected?
A3: The detachable dust cover is specifically designed for harsh environments. It protects the internal components from dust and debris, reducing maintenance needs and ensuring a longer lifespan for the inverter in industrial or densely populated urban areas.
Q4: Can I expand my system later as my energy needs grow?
A4: While the units themselves are not parallel-capable, you can start with a smaller model (e.g., 1.5KW) and later upgrade to a larger unit within the series (up to 6.2KW) as your family or business energy demands increase, protecting your initial investment.
Q5: How does the EQ function benefit my battery in Vietnam's climate?
A5: The EQ (Equalization) function helps optimize battery performance and extend its lifecycle by preventing stratification and sulfation. This is particularly beneficial in Vietnam's warm climate, which can accelerate battery degradation if not properly managed.
Q6: Is the WiFi monitoring secure and reliable?
A6: Yes, the optional WiFi module provides a secure and reliable connection for remote monitoring. You can confidently track your energy production and system health from your smartphone, ensuring your investment is performing optimally.
