Looking for a reliable and efficient solution for independent power generation? Our Solar Inverter off Grid is the answer. With its pure sine wave output, this inverter ensures a stable and high-quality power supply, just like the public power grid.
Our Solar Inverter is available in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have specific requirements, our engineers are available for consultation.
What sets our low frequency inverter apart from high frequency inverters is its superior adaptability to different environments and its strong protection features. It offers reliable performance and voltage regulation, making it a trustworthy choice for your power needs.
When it comes to the difference between pure sine wave and modified sine wave inverters, our pure sine wave output inverter stands out. It not only matches the quality of the public power grid but also surpasses it. With a low repair rate, long lifespan, and no harmonic pollution, our pure sine wave inverter is not only environmentally friendly but also protects your appliances.
On the other hand, modified sine wave output inverters can have a negative impact on appliances, especially those with inductive loads like air conditioners and refrigerators. Certain motor control circuits may not be compatible with the modified wave.
Our Solar Inverter is designed to handle a wide range of appliances, making it suitable for household, office, and agricultural use. It can easily load inductive appliances such as refrigerators, air conditioners, and water pumps.
If you're looking to customize your inverters with your company logo, we offer OEM orders to meet your branding needs.
Choosing the right inverter is crucial, and our sales team is here to assist you. Simply share your requirements, and we will recommend a suitable inverter for your specific needs.
Should you encounter any technical problems, our 24-hour after-service consultancy is dedicated to providing you with easy solutions.
While a power inverter is not absolutely required for a solar energy system, it is essential if you want to use normal AC appliances. Without a power inverter, you will only have battery power and won't have access to 220 or 230 volts AC.
The voltage of the inverter depends on the input voltage from the battery bank. Higher voltages allow for smaller wires between your solar panel array and battery bank. It's important to ensure that your solar panels, inverter, and battery bank all use the same voltage.
In the event that a product is broken, we offer after-sale service and provide spare parts of PCB board free of charge. Simply send us a picture or video of the faulty product, and we will study it to determine the best solution.
Choose our Solar Inverter off Grid for reliable, efficient, and independent power generation. Experience the benefits of clean and renewable energy with our advanced technology.
