FAQs

1. What is a solar inverter, and why is it important?
   A solar inverter converts the DC electricity generated by solar panels into AC power that can be used by household appliances or fed into the electrical grid. It’s essential for any solar installation.
2. What’s the difference between a string inverter and a solar micro inverter?
   String inverters serve multiple panels at once and are cost-effective for uniform arrays. Solar micro inverters, on the other hand, are installed on each panel, maximizing output at the module level especially useful in shaded or irregular setups.
3. How do I calculate expected energy output from a solar system?
   Using a solar power calculator kWh, you can estimate daily or annual energy production based on panel capacity, inverter efficiency, sun exposure, and location.
4. Is it better to buy wholesale solar inverters?
   Yes for installers and distributors, buying in bulk usually reduces unit cost, improves inventory control, and ensures availability for client projects.
5. How do I choose the right solar inverter supplier for my business?
   Consider product range, performance specs, warranty support, pricing, and logistics. Align these factors with your project needs and customer expectations to make a well-informed decision.
