FAQs proposed by different countries:
1. Philippines
Q1: Is the GM inverter suitable for areas in the Philippines prone to frequent brownouts and voltage fluctuations?
A1: Absolutely. The GM inverter features a wide AC input voltage range (90-280VAC), allowing it to handle the common voltage fluctuations and brownouts. It can seamlessly switch to battery or PV power when the grid fails, ensuring an uninterrupted power supply for your home or business.
Q2: Can this system power a typical Filipino household with appliances like air conditioners, refrigerators, and fans during a blackout?
A2: Yes. With models offering 5500W to 6200W of pure sine wave output, it can easily run essential appliances, including air conditioners. You can program the supply priority to use solar and battery first (SBU mode), maximizing savings and backup during outages.
Q3: How does the inverter perform during the rainy season when sunlight is limited?
A3: The inverter is designed for high efficiency, starting with a low PV voltage of 120VDC. While solar harvest is reduced on cloudy days, the system can automatically charge the battery using grid power (if available) as a backup, ensuring you are never without power.
Q4: Is it difficult to get support and installation for this product in the Philippines?
A4: The GM series is designed for straightforward installation. Furthermore, we have a growing network of certified installers and partners across the major islands to provide professional installation, training, and after-sales support.
Q5: With net metering policies, can I really reduce my electricity bill?
A5: Definitely. The "Feed-in to the Grid" feature, controlled by the external CT sensor, allows you to export excess solar energy to the utility grid. Under the Philippines' net metering program, this can significantly offset your electricity consumption, leading to lower monthly bills.
Q6: The environment can be humid and dusty. Is the inverter built for this?
A6: Yes. The GM inverter comes with a detachable dust cover, protecting its internal components in harsh environments. Its operating humidity range of 5%-95% (non-condensing) makes it well-suited for the Philippine climate.
2. Vietnam
Q1: Does the GM inverter comply with EVN's grid connection regulations?
A1: The GM inverter includes essential safety features like backflow prevention via an external CT sensor, which is a critical requirement for EVN compliance. It ensures no excess power is fed back into the grid unless intended and approved, making it a safe and compliant choice.
Q2: How can this system help my small business during peak electricity pricing hours?
A2: By using the programmable supply priority, you can set the system to rely primarily on solar and battery power during peak daytime hours when electricity rates are highest. This "peak shaving" capability dramatically reduces your demand from the grid and cuts energy costs.
Q3: My roof gets strong sunlight, but it's very hot. Will the inverter's performance drop?
A3: The inverter's operating temperature range is up to 50°C. Its efficient design ensures stable performance even on hot days. For optimal longevity, we recommend installing it in a shaded, well-ventilated area.
Q4: Can I expand the system in the future as my energy needs grow?
A4: Yes. A key feature of the GM series is its parallel capability, allowing you to connect up to 12 units. You can start with a single unit and easily add more inverters later to increase your power capacity without replacing the entire system.
Q5: Is the WiFi monitoring easy to set up for someone who is not tech-savvy?
A5: Yes, it's very simple. The direct plug WiFi dongle is a plug-and-play device. Once connected, you can use a smartphone app to easily monitor your system's performance, energy production, and consumption in real-time.
Q6: What is the EQ function, and is it useful for the lead-acid batteries commonly used here?
A6: The Equalization (EQ) function is crucial for maintaining lead-acid batteries. It applies a controlled overcharge to balance the battery cells, sulfate the plates, and extend the battery's overall lifespan, ensuring you get the best value from your investment.
3. Indonesia
Q1: With thousands of islands, many areas in Indonesia have weak or no grid. Can this inverter work completely off-grid?
A1: Yes, the GM series offers a dedicated off-grid operation mode. It can create a stable, independent power source using solar and batteries, making it an ideal solution for remote villages, islands, and homes without access to a reliable grid.
Q2: How does it handle frequent lightning strikes and power surges common in tropical regions?
A2: While the inverter has built-in protections, we strongly recommend using external lightning arrestors and surge protection devices on both the AC and DC sides for maximum safety, which is a standard practice in Indonesian installations.
Q3: What is the advantage of the high 500VDC PV input voltage?
A3: The high voltage allows you to use longer, thinner, and more cost-effective DC cables. This is particularly beneficial for larger installations where the solar panels are far from the inverter, reducing power loss and installation costs.
Q4: Can I use this for a small workshop with machinery?
A4: Certainly. The pure sine wave output ensures that even sensitive machinery and tools run smoothly without risk of damage. The 6200W model can handle significant loads, supporting various workshop equipment.
Q5: Does it support lithium batteries, which are becoming more popular?
A5: Yes, it does. The GM inverter has specific settings for lithium batteries, including communication protocols for BMS integration and a function to activate them using either PV or utility power, offering you modern, efficient energy storage options.
Q6: What happens during a long period of cloudy weather?
A6: The system is designed for hybrid operation. If the battery runs low and solar is insufficient, it will automatically and seamlessly start drawing power from the grid (if available) to supply your loads and recharge the batteries, ensuring constant power.
