FAQs proposed by different countries:

1. Thailand

Q1: Can I use this inverter to participate in Thailand's Very Small Power Producer (VSPP) scheme?
A1: The GM inverter's grid-tie functionality with feed-in capability is the foundational technology needed for such schemes. It allows you to generate and export solar energy, making it possible to become a small-scale power producer and generate revenue.

Q2: Is it suitable for a typical Thai townhouse with limited installation space?
A2: Its compact design (approx. 448*315*122mm) is perfect for space-constrained installations. It can be mounted on a wall in a utility area, and its quiet operation ensures it won't be a disturbance.

Q3: How does the "No Battery Mode" benefit me?
A3: This mode allows the inverter to operate as a standard grid-tie solar inverter without a battery. It directly converts solar power for your home use, reducing grid consumption. This is a cost-effective way to start your solar journey, and you can add batteries later for backup.

Q4: The sun is intense here. Will the high solar radiation damage the PV input?
A4: The inverter's Maximum PV input voltage is 500VDC, which is well above the operating voltage of most standard solar panel strings. It is designed to handle the high performance of panels in high-solar regions safely.

Q5: Can I monitor my system's performance from my office in Bangkok if my house is in Chiang Mai?
A5: Yes. With the optional WiFi dongle, you can monitor your system's real-time data, historical energy production, and status from anywhere in the world with an internet connection, giving you complete peace of mind.

Q6: What does "PF=1.0" mean, and why is it important?
A6: Power Factor 1.0 means the inverter draws real power from the grid with perfect efficiency, without reactive power. This is important because some utility companies charge penalties for a low power factor. Our inverter ensures you avoid these extra charges.

2. Malaysia

Q1: Does this system comply with SEDA's guidelines for solar photovoltaic installations?
A1: The GM inverter's features, including grid-tie operation with feed-in control and relevant safety certifications, align with the requirements for systems connected to the grid in Malaysia. We recommend working with a SEDA-registered installer for full compliance.

Q2: How can it help during the haze season when solar generation drops?
A2: During periods of haze, the inverter's MPPT controller is highly efficient at harvesting available light. Furthermore, the system will intelligently use grid power to supplement the reduced solar input and ensure your battery remains charged for backup needs.

Q3: Is the parallel function useful for a large Malaysian family home?
A3: Yes. Parallel operation allows you to combine the power of multiple inverters. For a large home with high energy demands (e.g., multiple AC units, water heaters), you can run 2 or 3 units in parallel to achieve 11kW to 18.6kW of power, ensuring all needs are met.

Q4: What is the warranty and service support like in Malaysia?
A4: We have a dedicated distributor and service partner network in Malaysia offering comprehensive warranty support and technical services. You can invest with confidence, knowing professional help is readily available.

Q5: Can I set the inverter to charge my batteries only at night using off-peak grid electricity?
A5: Yes. The user-adjustable charging current and voltage settings allow you to create a custom charging schedule. You can program the system to charge the batteries from the grid during off-peak, low-tariff hours, maximizing cost savings.

Q6: What is the difference between SUB and SBU mode?
A6: In SUB (Solar-Utility-Battery) mode, the inverter will use Solar first, then Utility, and finally Battery. In SBU (Solar-Battery-Utility) mode, it uses Solar first, then Battery, and only uses the Grid as a last resort. This gives you full control over your energy strategy.

3. Nigeria

Q1: Can this inverter power my home through Nigeria's frequent and prolonged power outages?
A1: Absolutely. The GM series is built for this exact scenario. With its high-capacity solar charging (up to 120A) and large battery support, it can keep your essential loads running for hours during a grid outage, using free energy from the sun.

Q2: My generator is loud and expensive to run. Can this system work with it?
A2: Yes. The inverter can be configured to use a generator as an AC input source. It can automatically start the generator to charge the batteries if they run too low, and then shut it off, reducing generator runtime, fuel costs, and noise.

Q3: Is it robust enough to handle the heat and dust in places like Lagos or Kano?
A3: The inverter is designed for harsh environments. Its operating temperature goes up to 50°C, and the detachable dust cover protects its internals. This ensures reliable performance in Nigeria's challenging climate.

Q4: What is the maximum solar panel capacity I can connect?
A4: For the GM6200 model, you can connect up to 6500W of solar panels. This high capacity allows you to maximize solar generation during the day, power your home, and fully charge your batteries, minimizing reliance on the unreliable grid or generator.

Q5: How does the CT sensor prevent backfeeding in an unstable grid?
A5: The external CT sensor constantly monitors grid import/export. In areas with unstable grids, it is crucial to prevent any accidental backfeed for safety. The inverter uses this sensor to precisely control the power flow, ensuring zero export to the grid unless intentionally enabled and safe to do so.

Q6: I use lead-acid batteries. How does the EQ function help me?
A6: The EQ function is a periodic maintenance charge that helps prevent stratification and sulfation in lead-acid batteries, which are common issues that shorten battery life. Using this function can significantly extend the lifespan of your battery bank, protecting your investment.
