Seller's Command:

1.Note: this item is 48V DC Input, usually when you use big power,the best Input voltage is 48V,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 coutnry 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℃.

UPS : Use your ac home power first, if out of ac power, auto switch to dc bank power.If the machine is connected to the battery and home mains at the same time, the machine priority to use the home mains electricity, if the home mains electricity is failure, the machine will be automatically converted into Inverter function to run the home appliances.

ATS: Use your solar or battery power first, if out of dc power, auto switch to ac power & charge your battery bank at the same time.

If the machine is connected to the battery and home mains at the same time, the machine will use Inverter function first. When the battery voltage is lower than 10.5V(for 12V inverter) or 21.5V(for 24V inverter), the machine will automatically switch to charging mode. In charging mode, the AC output will be from home mains. When the battery voltage rises to 14V(for 12V inverter) or 28V(for 24V inverter), the machine will automatically convert back to Inverter function, when switching the function will not affect the use of appliances.

when you use ATS function,it need to turn off the power inverter first,then plug the AC input into home grid,then turn on the power inverter,this moment it will charger the battery and with AC output at the same time,AC output come from home grid,make sure turn off the power inverter first then plug the AC input then use the ATS function,thanks

POWER SAVE ON :

If you only connect battery with load, ac cable unconnect, when you switch to battery charger mode, this means is

power save mode on, in this moment the condition as follows: The inverter will go to sleeping mode , no load current is 0 AMP, every 3secs, the inverter will detection itself, after the 3sec, amp will go to 3amp(stand by power, time: 1sec, then back to sleep mode, amp is 0),  the inverter will repeat the situation, until you switch to power save off(inverter on, down side)

some customer need use refrigerator ，can switch to power save on mode, as refrigerator only will work every  half an hour or one hour  ,  but inverter stay in power save function, no load current is 0amp , can save power.

When toggled this inverter will power on every 4 seconds and check for a load of 25 watts or greater. If no load is detected it will power down and wait 4 seconds. This mode is perfect for items that do not run continuously such as refrigerators and freezers. It will save on standby draws where energy saving is critical. This mode uses approximately 1/3 the standby draw.
