FAQs proposed by different countries:
1. South Africa
Q1: How can the GM inverter help me during loadshedding stages?
A1: This inverter is an ideal loadshedding solution. It provides instantaneous switchover to battery power the moment the grid fails, keeping your lights, internet, TV, and essential appliances on without any interruption through all stages of loadshedding.
Q2: Is it NRS-certified for legal grid connection in South Africa?
A2: The inverter is designed with international grid standards in mind. We are actively pursuing NRS 097-2-1 certification for the South African market. Please check with your supplier for the latest certification status of available models.
Q3: Can I use it to reduce my dependence on Eskom's ever-increasing tariffs?
A3: Without a doubt. By maximizing solar self-consumption, you directly reduce the amount of electricity you need to buy from Eskom. The feed-in capability also opens the possibility for future small-scale embedded generation programs, turning your roof into a source of savings.
Q4: What size system do I need for a 3-bedroom house in Johannesburg?
A4: The 5.5kW model is an excellent starting point for a typical 3-bedroom home, capable of running lights, TV, fridge, computer, and a small air conditioner. For homes with higher consumption (e.g., geysers, pool pumps), the 6.2kW model or a parallel system is recommended.
Q5: How reliable is the WiFi monitoring with sometimes unstable internet?
A5: The monitoring system stores data locally on the device. If the internet connection drops, it will continue logging, and once the connection is restored, it will sync all the historical data to the cloud, so you never lose track of your system's performance.
Q6: Does the high PV voltage range help with winter generation?
A6: Yes. Solar panel voltage increases in colder weather. The wide MPPT voltage range (60-500VDC) ensures the inverter can still efficiently harvest energy from your panels during the cold, sunny winter days in South Africa, optimizing year-round production.
2. Kenya
Q1: Is this system suitable for off-grid applications in rural Kenya?
A1: Perfectly. The GM inverter's robust off-grid capability allows it to form a stable micro-grid for a home, school, or clinic in remote areas, powered entirely by solar energy and batteries, providing reliable electricity where the national grid does not reach.
Q2: Can it handle the high-altitude conditions found in some parts of the country?
A2: The inverter's design is suitable for a range of environmental conditions. While it's always best to install in a controlled environment, its components are rated to perform reliably at various altitudes typical across Kenya.
Q3: How does the "Lithium Battery Activation" feature work?
A3: If a lithium battery enters a protection mode and shuts down due to complete discharge, this feature allows the inverter to use available PV or grid power to "wake up" and reactivate the battery, a valuable and convenient safety feature.
Q4: What is the benefit of the high solar charging current?
A4: With a maximum solar charging current of 120A (on the GM6200 model), the inverter can quickly recharge a large battery bank during short hours of peak sunshine. This is crucial in regions with consistent sun patterns, ensuring your batteries are full by midday.
Q5: Is the installation process complicated?
A5: The inverter is designed for straightforward installation by a qualified electrician. The ports are clearly labeled, and comprehensive manuals are provided. We also have technical support available for installers in Kenya.
Q6: Can I power a small water pump for irrigation with this inverter?
A6: Yes, the pure sine wave output is clean and stable, suitable for running single-phase AC water pumps. This allows you to use solar power for agricultural activities, reducing operational costs and increasing farm productivity.
3. Egypt
Q1: With Egypt's abundant sunshine, how can I maximize my solar energy usage with this inverter?
A1: The GM inverter's high-efficiency MPPT (94% conversion efficiency) ensures you get the most power from your solar panels. You can set the supply priority to "SBU" to use solar energy to power your loads and charge batteries first, before drawing any power from the grid.
Q2: Can it withstand the extreme heat and sandstorms in desert areas?
A2: The inverter is rated for temperatures up to 50°C. For installation in very hot and dusty regions, we recommend placing it in a shaded, indoor, and well-ventilated location. The detachable dust cover offers additional protection against fine sand particles.
Q3: Does it support the three-phase grid common in commercial applications?
A3: While a single unit is single-phase, you can connect up to 12 units and configure them for 3-phase output. This makes the GM series scalable from a single home to a large commercial business, providing balanced three-phase power.
Q4: What is the "Initial Feeding Voltage" of 120VDC?
A4: This is the low voltage at which the inverter starts feeding solar power into your home's circuits. A low start-up voltage means it begins generating power earlier in the morning and continues later in the evening, maximizing your daily energy harvest.
Q5: How can the remote monitoring help me as a business owner?
A5: You can monitor the performance of multiple systems from a single dashboard. Track energy savings, system health, and ROI across different branches or locations, enabling efficient fleet management of your solar assets.
Q6: Is the output voltage stable for sensitive medical equipment?
A6: Yes, the pure sine wave output is as clean and stable as, or even better than, the power from the grid. This makes it perfectly safe for powering sensitive devices like medical equipment, computers, and high-end audio/video systems.
