Frequently Asked Questions (FAQ)

1. What is the difference between a 3kVA and 3kW inverter?
The kVA (kilovolt-ampere) represents the apparent power, while kW (kilowatt) represents the actual real power. For our 3kVA inverters with a power factor of 1.0, the output is a full 3000W. If the power factor is 0.8, the output is 2400W. We offer both configurations based on your market needs.
2. Can your 3kVA solar inverters work without a battery?
Yes, our high-voltage off-grid series can operate in "Battery-less" mode, where the inverter powers the load directly from PV panels during the day, significantly reducing the initial system investment.
3. How do you ensure the quality of OEM orders?
Every unit undergoes an automated ATE test after assembly and a minimum of 8 hours of full-load burn-in testing. We also perform random OQC (Outgoing Quality Control) inspections to ensure 100% compliance with your brand's standards.
4. What is the typical lead time for a container-level order?
For standard models, the lead time is 20-25 days. For highly customized ODM projects, the initial prototype takes 30-45 days, with mass production following shortly after.
5. Do you support Lithium battery communication?
Absolutely. Our inverters support RS485/CAN communication with major LiFePO4 battery brands like Pylontech, Growatt, and BYD, allowing the inverter to manage the battery's SOC (State of Charge) accurately.
