FAQs for Different Countries
Introduction: Developed for Brazil's unique grid frequency and sunny climate, this inverter provides a reliable and efficient energy solution for residential and commercial applications.
FAQ:
Q: Is this inverter compatible with Brazil's 60Hz and 220V/127V grid system?
A: The nominal output of 220V/230V/240V and 60Hz frequency is a perfect match for the standard 220V lines in Brazil. For 127V circuits, a transformer would be needed, which is a common practice.
Q: How does it handle high temperatures in regions like the Northeast?
A: The operating temperature up to 60°C and natural cooling make it well-suited, though installation in a shaded, well-ventilated area is recommended for peak performance in consistently hot climates.
Q: What is the maximum AC output current? Is it enough for a Brazilian home?
A: With up to 28.7A, it can supply ample power for a typical Brazilian household, including multiple appliances.
Q: Can it help during frequent apagões (blackouts)?
A: Absolutely. The seamless transfer to backup power (<10ms) means your home will have uninterrupted electricity during most blackouts, a significant advantage.
Q: Is the IP66 rating sufficient for tropical rain?
A: Yes, the IP66 rating means it can withstand powerful water jets, making it more than capable of handling heavy tropical rainfall.
Q: What is the start-up voltage, and is it good for cloudy days?
A: The low start-up voltage of 90V means it begins operation earlier in the morning and continues later in the afternoon, as well as on cloudy days, maximizing energy capture.
Q: Are the MC4 connectors standard and safe?
A: Yes, the PV connection uses standard MC4 connectors, which are globally recognized for their safety and ease of use.
Q: How can I monitor my energy generation and consumption?
A: Use the intuitive mobile APP over Bluetooth. For whole-home consumption monitoring, an additional meter connected via the RS485 port is required.
Q: What is the warranty period offered in Brazil?
A: We provide a 5-year warranty as standard, with the possibility to extend to 10 years for added security.
Q: Is it protected against voltage spikes from the grid?
A: Yes, it includes overvoltage protection (AC Type III) and surge arresters to safeguard the electronics from common grid instability issues.
Introduction: Tackle load-shedding head-on with our inverter, designed to provide reliable backup power and significant savings on electricity bills for South African homes and businesses.
FAQ:
Q: Is this inverter suitable for the South African grid (230V, 50Hz)?
A: Perfectly. The nominal voltage of 230V and 50Hz frequency align exactly with the South African standard.
Q: What is the real benefit of the high battery discharge power during load-shedding?
A: With up to 6,600W of discharge power, you can run a high-wattage kettle, geyser element, or multiple air conditioners simultaneously during stages of load-shedding, maintaining a normal lifestyle.
Q: How does the high PV input power help during the day?
A: It allows for a large solar array to power your home and rapidly recharge your batteries between load-shedding stages, ensuring you are always prepared.
Q: Can it withstand the heat in a North-Facing roof space in summer?
A: Its high-temperature tolerance (up to 60°C) is crucial for South African summers. Installers should ensure adequate ventilation in the roof space for best results.
Q: What is the advantage of the 360V battery system?
A: It is more efficient and cost-effective than lower-voltage systems, meaning you get more usable power from your battery bank, which is vital during extended load-shedding.
Q: Is the transfer time truly less than 10ms?
A: Yes, the typical transfer time is under 10 milliseconds, so sensitive electronics like computers and TVs will not flicker or shut down during the switch.
Q: How durable is it for outdoor installation?
A: The IP66 rating and robust construction make it suitable for outdoor installation, resistant to dust and rain, though protection from direct, extreme weather is always best.
Q: Can I use it with lead-acid batteries, which are more common here?
A: Yes, it fully supports lead-acid batteries, allowing for a more budget-friendly initial storage solution.
Q: How easy is it to get support and warranty service?
A: We work with a network of certified partners across South Africa to provide local technical support and honor the 5/10-year warranty.
Q: Does it have protection against lightning surges?
A: Yes, integrated Type III surge arresters on both DC and AC sides provide a good level of protection against induced surges from nearby lightning strikes.
Introduction: Ideal for Mexico's sunny and diverse climate, our inverter offers high performance, energy independence, and a reliable power backup solution for modern households.
FAQ:
Q: Is the inverter compatible with Mexico's 127V/220V dual voltage system?
A: The adjustable output voltage covers 220V/230V/240V, making it directly compatible with 220V circuits. For 127V circuits, an external autotransformer is typically used in Mexican installations.
Q: How does the efficiency help with high electricity costs in Mexico?
A: By converting more solar energy into usable AC power, the high efficiency directly translates into lower CFE bills, making solar investment more lucrative.
Q: What is the benefit of the wide battery voltage range (80V-480V)?
A: This wide range provides great flexibility in battery configuration and state of charge, allowing the battery to be deeply discharged when needed without damaging the system.
Q: Can it handle the humidity in coastal areas like Cancun?
A: The IP66 rating protects against moisture, and the unit can operate in 0-100% relative humidity, making it suitable for humid coastal climates.
Q: Is the 60Hz frequency setting available?
A: Yes, the nominal grid frequency is selectable for 60Hz, which is the standard in Mexico.
Q: What is the max AC output power, and what can it run?
A: With max AC output power up to 6,600W (PF=1), it can power an entire household, including multiple air conditioning units, refrigerators, and lighting.
Q: How safe is the DC connection for installers?
A: It includes DC reverse polarity protection and a DC switch, preventing damage from incorrect wiring and allowing for safe isolation during maintenance.
Q: Can I monitor my system without an internet connection?
A: Yes, the Bluetooth and APP connection allows for full monitoring and configuration directly from your smartphone without needing Wi-Fi.
Q: What is the standard warranty in Mexico?
A: The product is backed by a 5-year manufacturer's warranty, with an optional extension to 10 years for greater security.
Q: Does it work at high altitudes found in some Mexican cities?
A: It is rated for operation up to 4000m, which is more than sufficient for all populated areas in Mexico, including cities at high altitude.
