Frequently Asked Questions
1. What is the difference between a pure sine wave and a modified sine wave inverter?
Pure sine wave output is as stable as the public power grid, ensuring low repair rates, long lifespan, and protection for sensitive appliances like refrigerators and air conditioners. Modified sine waves can negatively impact inductive loads and certain motor circuits.
2. What kind of appliances can this solar inverter load?
Our inverters are versatile and can be used for household, office, and agricultural appliances, including inductive loads such as water pumps, air conditioners, and refrigerators.
3. Do I absolutely need a power inverter for my solar system?
Technically no, but without one, you will only have DC battery power. An inverter is essential if you want to use standard AC appliances (220V/230V) in your home or RV.
4. How do I choose the right inverter for my needs?
Selection depends on your total power demand. We offer ranges from 300W to 3000W; simply match the inverter capacity to the peak load of the appliances you plan to run simultaneously.
5. What should I do if the product is faulty?
We provide a 3-year warranty. If a product is faulty, we analyze the issue via photos or videos and supply free PCB board spare parts for after-sales service.
6. Is the system easy to install for non-professionals?
Yes, it is a plug-and-play system. Users only need to connect the solar panel to the main power box and turn on the switch to start supplying electricity.
