FAQs from Different Countries
1. Philippines
Q1: Is the EM Series inverter stable enough for the frequent brownouts and voltage fluctuations common in the Philippines?
A: Absolutely. The inverter has a wide AC input voltage range (90-280VAC for home appliances), which means it can handle the unstable grid power typical in many areas. Its pure sine wave output also ensures your sensitive electronics are protected.
Q2: Can it withstand the high humidity and typhoon-season weather?
A: Yes. The detachable dust cover provides protection against moisture and dust. Its operating temperature range (-10°C to 50°C) and high humidity tolerance (5%-95% non-condensing) make it highly suitable for the Philippine climate.
Q3: I have a small business that runs on PCs. Will the 10ms transfer time prevent my computers from shutting down during a power cut?
A: Definitely. The ultra-fast 10ms transfer time is specifically designed for personal computers, ensuring seamless switchover to battery power without interruption, keeping your business running smoothly.
Q4: Is it compatible with the lithium batteries available in the local market?
A: Yes. The inverter features built-in RS485 communication for seamless compatibility with most major Lifepo4 battery brands available here. It can even activate a fully drained lithium battery using solar power.
Q5: With high electricity costs, can I really run my essential appliances without a battery using just solar panels?
A: Yes! The "No Battery Mode" is a key feature. During the day, you can power your appliances directly from your PV panels, drastically reducing your electricity bills and maximizing your solar investment.
Q6: What kind of after-sales support can I expect locally?
A: We have established partnerships with certified installers and service centers across major islands to provide you with reliable installation, maintenance, and technical support.
2. Vietnam
Q1: My roof gets sun all day. What is the maximum solar panel power the EM5.5KW model can handle?
A: The EM5500-48L can support a large PV array of up to 5500W, perfectly utilizing the strong Vietnamese sun. Its MPPT range (60-500VDC) allows for flexible, high-voltage panel strings.
Q2: Does the inverter meet the standards for connecting to the local grid (if applicable)?
A: While primarily an off-grid inverter, its output specifications (220/230VAC ±5%, 50Hz) are fully compatible with the standard voltage in Vietnam. Always check with local authorities for any specific grid-interconnection regulations.
Q3: The inverter makes a humming sound?
A: A slight hum is normal under heavy load due to its high-frequency transformer design, which is more efficient and compact. It is not a sign of malfunction.
Q4: Can I use this for a 3-phase application for my small workshop?
A: No, the EM Series are single-phase inverters. For 3-phase applications, multiple units can be configured by a professional, but it is not a standard parallel capability.
Q5: How does the "SBU" output priority mode help me save money?
A: In SBU mode, it uses Solar power first, then Battery, and only uses Utility grid as a last resort. This prioritizes your free solar energy, minimizing grid consumption during peak tariff hours.
Q6: Is the WiFi monitoring easy to set up for remote management?
A: Yes, the optional WiFi dongle offers plug-and-play setup. You can easily monitor your system's performance, energy savings, and receive alerts directly on your smartphone from anywhere.
3. Indonesia
Q1: I live in a remote area without any grid power. Can this system power my entire home?
A: Yes, the EM Series is designed for off-grid living. Starting from the 1.5KW model for basic needs up to the 6.2KW model for larger homes, you can run appliances like refrigerators, fans, lights, and TVs reliably.
Q2: How does the MPPT charger perform on cloudy days, which are common here?
A: The high-efficiency MPPT controller (up to 96% PV-to-INV) is excellent at harvesting available solar energy, even in low-light or cloudy conditions, ensuring you get the most power possible from your panels.
Q3: Is it safe for my family and my home?
A: Safety is paramount. It includes comprehensive protections: overcharge protection for your battery, overload protection, and a pure sine wave that is safe for all household electronics. Proper grounding is essential and clearly marked.
Q4: Can I expand my system later if my energy needs grow?
A: While the inverters themselves cannot be paralleled, you can start with a higher-capacity model than you currently need. You can always expand your solar array and battery bank later to grow with your system.
Q5: What does the "EQ function" do for my lead-acid batteries?
A: The Equalization function helps to de-sulfate and balance the electrolyte in lead-acid batteries, which can significantly optimize their performance and extend their lifespan, a crucial feature for a long-term investment.
Q6: Are the components resistant to corrosion in coastal areas?
A: The unit is built with a robust casing and treated components to resist environmental factors. For extreme coastal salinity, we recommend installing it in a well-ventilated but protected enclosure for added longevity.
