Choosing the right inverter?
First step is to establish the power required to run your equipment. Most appliances/ tools
have their wattage stamped on the nameplate or listed in the owner's manual. Simply add your
appliance wattages together to arrive at a total figure. If you find you can only local the amps,
use this simple calculation:240volts* Amps =Watts.
Step two is selecting the correct size inverter. Resistive load(lights, chargers, etc.) only
require yourinverters rated output. Inductive loads such as an air conditioner,refrigerator/f
reezer requires 5,7 times the continuous rating, e.g. an 80w refrigerator requires a 600w
inverter. Power tools, fluorescent lights, TV also requires 3,4 times more wattage at start up.
Therefore you would need a 1000W inverter to power a 250W drill.
Keep in mind, it's an inverter, not a power station, choosing an inverter with 25-30% above
your needs is recommended. If you're unsure of your requirements, ask us or a licensed
electrician.

protection( low voltage protection, high voltage protection, high temperature
protection, short circuit protection, leakage protection, overcurrent protection,
overload protection, low voltage recovery, high voltage recovery, intelligent
temperature control, solid barrier alarm).
Q 2. What's the payment terms?
A. T/T or Paypal
Q 3. How's the delivery time?
A. It takes 1-3 days for sample order after your payment, also according to your order quantity.
Q 4. How's the standard of package?
A. Use strong wooden case for protection, also can according to your requirement.
Q 5. What kind of material of transformer?
A. We use the new 100% pure copper transformer, which made the inverter has
high efficiency convertion, stable, high quality etc.
Q 6. What's the difference between 12, 24, and 48 volt inverters?
A. This refers to the input voltage from the battery bank. The main consideration
is that at higher voltages the current is less so that you can use smaller wires
between your solar panel array and your battery bank. Of course, when you
decide on a system voltage, the Solar Panels, Inverter, and Battery Bank all need
to use the same voltage.
Q 7. What kind of certificate you have?
A. Our company has already achieved CE, EMC certification.
