Seller's Command:

1.Note: this item is 12V DC Input, usually when you use big power,the best Input voltage is 12V,because the amp will become small, will not cause the inverter getting so hot, if inverter not hot, the efficiency will arrive 2-3%,means can go to 92-94%, also your battery bank can keep very good performance! watt=volt x amp, once your voltage getting high, your amp will become small.

2 .this inverter will come unversal plug with big amp socket, all the country can be used!.

3.this inverter is LF inverter, we called low frequency, with big transformer inside(around 12kgs),this design just for the heavy duty appliance, like pump, motor, freezer, grinder, microwave, heater.

I sold the inverter about 10more years, most of is HF INVERTER(made by mosfet), even it's 5000w inverter,

still get some feedback from customers side, they say why i use pump, grinder can not turn it on? or use some weeks, the inverter dead, because some heavy appliance maybe just 500w, however, when turn it on need 10-15times conitnue power(5kw-7.5kw) to start it, in this moment, very easy to damage the mos-fet, it happened all the time, i am very upset about this situations & no idea to real solve the problem. 

One day my friend who is engineer to charge the power source about the airplane & train, he told me can think about the LF INVERTER, as all the airplane, train, big board, RV CAR, they are set up this inverter with no problem.I go to find how this inside made, the major point is big transformer, made by a wide copper, very strong enough 100times than HF INVERTER(made by mosfet) to produce smooth power & of course, even 5-8years after, the transfomer still working good!

4. you may see a lot of inverter in the marketing for sell, price will be hurge different, 80% is HF INVERTER, because its' handy 3kw around 5-6kgs, 5kw around 10kgs, but before you make a choice, just asking can this run microwave, compressor, pump?  You may not get very satisifed answer, that's the big difference!

What i recommend is just spend your money for power source at 1 shot can real useful, real match your power source demand.

5.TURBO POWER AUTO DETECTION: 

 when you use some motor, engine, pump, some need 10 times surge power require, in this moment, the IC will auto offer more amp come from the battery with 2 times standby power to turn on the heavy appliance, after turn it on, the amp will come to normal voltage & amp.

6.  Inside big transformer is made by Taiwan factory, material come from Japan, that's bring the inverter efficiency come maintain to 92% at least.

7.  Inside mosfet from Germany, not made in China, that's making sure the inverter for long time use, will be no problem, temperature can stay around 60℃.
