FAQ
Q1 : What's the different between inverter and solar inverter?
Inverter is only accept AC input, but solar inverter not only accept AC input but also can connect with solar panel to accept DC
input, it more save power.
Q2: What should be noticed when installing inverter?
Put the product in a place where is well ventilate,cool, dry and water-proof. Do not stress or put foreign objects into the
inverter. Remember to turn on the inverter before turn on the appliance.
Q3: Do we need to set the parameter before using ?
No need, our preset parameters can already meet your normal use.
And our inverter is AI intelligent working.
If you need to adjust the parameters yourself, you can do it in a few simple steps.
Q4: What is the payment terms?
100% T/T in advance for sample order. 50% T/T in advance, banlance 50% T/T before delivery for bulk order.
