Frequently Asked Questions
What's the difference between inverter and solar inverter?
Standard inverters only accept AC input, while solar inverters can connect with solar panels to accept DC input, providing significant power savings.
What should be considered during installation?
Install in well-ventilated, cool, dry, and waterproof locations. Avoid stressing the unit or inserting foreign objects. Always turn on the inverter before connecting appliances.
What are the payment terms?
100% T/T in advance for samples; 30% T/T deposit with 70% balance before delivery for bulk orders.
What is the delivery time?
3-5 days for samples; 15-25 days for bulk orders.
