12V 24V DC-AC inverter --FAQ:

Question 1---Does the inverter connect with solar system ?
Answer；
 Yes.
 Because of the unique feature which combine invert, charge and AC auto-transfer switch into one complete system, inverter not only connect with solar system, also could be used in officer equipment, household items, power tools and etc.

Question2:Does you inverter is off-grid or grid tie?
Answer:
 All of our inverter can customized is off-grid at present.

Question 3: Does this kind of inverter has battery charger function?
Answer:
 No.
 If need, please choose our YK-W7 series.

Question 4: All inverters are the transfer type of DC to AC?
 Yes
 Inverters are the type of DC to AC.
 According to customer’s requirement.
The AC output can be made such as 110V/120V/220V/230V/240V/380V.400V/415V

Question 5: How many kinds of output wave form for inverters?
 Two kinds. Pure sine wave and modified sine wave.
 Pure sine wave inverter could provide high quality AC and carry various loads, while it requires high tech and high cost.
 Modified sine wave inverter load poorly not carrying inductive load, but the price is moderate.

Question 6: How to choose suitable inverter?
Answer:
 If your load is resistive loads, such as: bulbs, you can choose a modified wave inverter. But if it is inductive loads and capacitive loads, we recommend using pure sine wave power inverter.
 For example: fans, precision instruments, air conditioner, fridge, coffee machine, computer, and so on.

Question7: How do I choose the suitable capacity /power of the inverter?
Answer:
 Different types of load demand for power are different. You can view the load power values to determine the size of the power inverter.
Notice:
 Resistive load: you can choose the same power as the load.
 Capacitive loads: according to the load, you can choose 2-5 times power.
 Inductive loads: according to the load, you can choose 4-7 times power.

Question 8:Does the output voltage of our inverter stable ?
Answer:
 Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value by a multimeter.
 Actually the output voltage is quite stable. Here we need make a especial explanation : many customers found it is unstable when using conventional multimeter to measure voltage. We can say the operation is incorrect. Ordinary multimeter can only test pure sine waveform and calculate data

Question 9:What should be noticed when installing inverter?
Answer:
 Put the product in a place where is well ventilate,cool, dry and water-proof.
 Pls do not stress and do not put foreign objects into the inverter.

Question10. Does this kind of inverter has LCD display?
Answer:
 No.If you need big quantity,can customize according to your request.
