Q1: With abundant solar resources, what is the maximum solar energy I can harvest daily?
A: The potential is enormous. For example, the EM6200 model can handle 6500W of solar panels. Under the clear Saudi sun, this can generate over 30kWh of electricity on a good day, enough to power a significant portion of a typical villa.
Q2: Can the system operate 24/7 under the extreme heat of the Arabian summer?
A: The inverter is rated up to 50°C. For 24/7 operation in peak summer, installing it in an air-conditioned or highly ventilated room is crucial to prevent overheating and ensure a long service life.
Q3: Is the pure sine wave output clean enough for sensitive medical equipment?
A: Yes, the output is a perfect, stable pure sine wave with low total harmonic distortion (THD), making it safe for powering sensitive medical devices, lab equipment, and high-end audio/video systems.
Q4: How does the warranty process work here?
A: We offer a comprehensive warranty backed by our regional office in Riyadh. The process is straightforward: contact our support team, and we will facilitate a repair or replacement through our authorized service centers.
Q5: Can I configure the charging voltages for different battery types (e.g., Gel, AGM)?
A: Yes, the charging voltage parameters (float, bulk) are user-adjustable through the display interface, allowing you to optimize the charge profile for Gel, AGM, or flooded lead-acid batteries.
Q6: Is the unit compliant with SASO standards?
A: Our products are engineered to meet rigorous international standards. We are actively working on obtaining the necessary SASO certifications for the Saudi market.
Q1: Is the inverter compatible with the 220V/60Hz standard used in Brazil?
A: Yes. The inverter's output is 220/230VAC and its frequency is 50/60Hz auto-sensing, making it perfectly compatible with the Brazilian electrical standard without any adjustments.
Q2: Can it handle the high startup current of a Brazilian freezer (freezer brasileiro)?
A: Completely. The high surge power (e.g., 11000VA for the 5.5KW model) is more than capable of handling the high compressor startup currents of Brazilian freezers and refrigerators.
Q3: With high grid instability in some regions, how fast is the transfer switch?
A: The transfer time is incredibly fast: 10ms for personal computers and 20ms for home appliances. This ensures your devices won't reset during the common micro-outages (apagões) or voltage drops.
Q4: What is the advantage of the high PV input voltage (500V)?
A: A high PV voltage allows you to connect more panels in a series string, reducing energy loss in the cables over long distances—a significant advantage for larger properties (sítios, chácaras).
Q5: Is local technical support available in Portuguese?
A: Sim (Yes). We have a Portuguese-speaking technical support team and partners in major cities to provide you with installation guidance and troubleshooting in your language.
Q6: Can I use it to sell energy back to the grid (net metering)?
A: No. The EM Series is an off-grid/hybrid inverter and is not designed for grid-feed (net metering). It is for self-consumption and backup power, protecting you from blackouts and high energy costs.
Q1: Given the voltage fluctuations, what is the actual working input voltage range?
A: The inverter can accept a very wide AC input range from 90VAC to 280VAC, making it exceptionally resilient to the severe voltage sags and surges that can occur in the Argentine grid.
Q2: Can I use it to power an electric heater during cold winters?
Q2: Can I use it to power an electric heater during cold winters?
A: Yes, but note that electric heaters are high-wattage devices. A 1500W heater would use nearly the full capacity of the 1.5KW model. We recommend sizing your inverter appropriately and considering energy-efficient heating alternatives.
Q3: Is the communication port (RS232/RS485) used for monitoring only?
A: No, these ports are also used for firmware updates, which allow us to provide performance enhancements and new features to your inverter over time, future-proofing your investment.
Q4: How does the inverter protect my battery from over-discharge?
A: The inverter has programmable low-voltage disconnect points. When the battery voltage drops to a critical level, the inverter will automatically shut off the output to protect the battery from damage, prolonging its life.
Q5: Are the dimensions and weight suitable for wall-mounting?
A: Yes, all models are designed for easy wall-mounting. The weight (from 6kg to 9kg) is manageable, and the dimensions are compact. Please use the provided mounting brackets and secure it to a solid wall.
Q6: What is the lead time for receiving a unit after ordering?
A: We maintain stock in our Buenos Aires warehouse for most models. Typically, orders are processed and ready for pickup or shipment within 2-3 business days.
