Product Q&A
Q:What is the difference between standard inverters and solar inverters?
A:
Standard inverters only accept AC input, while solar inverters accept both AC and DC input from solar panels for optimal power-saving.
Q:What are the delivery times for sample and bulk orders?
A:
Sample orders are delivered within 3-5 days. Bulk orders are typically fulfilled within 15-25 days.
Q:What warranty is provided for the inverters and pumps?
A:
Inverters come with a one-year warranty, while the VFD controlled pump (B1100 series) has a two-year warranty.
Q:What are the payment terms for orders?
A:
Sample orders require 100% T/T in advance. Bulk orders require 50% T/T upfront and 50% upon completion.
