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 arrive2-3%,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.
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!
5. this also including big 200amp battery charger, also you can do it like UPS, inverter, charger, almost offer your all power source demand.
6. 3.5" LCD display, watt, voltage, amp, very clear to understand your appliance situations.
News of 2015 VERSION
1. Made by Aluminum housing, from & back panel made by 2.5cm iron, strong enough to hold this big guy.
2. 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.
3. Inside big transformer is made by Taiwan factory, material come from Japan, that's bring the inverter efficiency come maintain to 92% at least.
4. 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℃.
5. UPS function:
a. usual UPS function is build-in battery, only can run about 5 mins.
b. however, this inverter can decide how long you want to use, the more high capacity battery you connect, then you can use whatever you want
c. Just connect the AC power cord to your home AC source, when out of AC power, the inverter will auto switch to inverter function, this can be your back power.
6. LCD meter function:
1. AC Output watt :0 Watt (Max display power 15KW，can display running power less than 1W )
2. AC Output Volt : 0 volt (Max display volt 270V)
3. AC Output Amp : 0 Amp (Max display amp 55A)
4. Total Operation time :0-60000 hours（Operation time: 0～59 minutes to 24 hours to 2500 days ）
5. Electricity consumption: 0～1000000 kwh
6. Electricity cost: 0～10000000 $
7. Total operation time , electricity consumption and electricity cost can clear
8. Can set up power ,the meter will alarm when reach reserve power
9. Can set up the cost
10. Refresh rate: one time 0.5 seconds
11. Messurement Accuracy: ±1%
Feature:
2012, power jack offer a low frequency psw inverter.
however, this has something need to improve
1. made by IRON PLATE, for long time use, not strong enough, as this big guy around 25kgs.
2. some heavy appliance still can not work it very perfectly, like motor, pump, influcent light,kettle,grinder,induction cooker
Now our Third generation, 2015 new version Low Frequency Pure Sine Wave Power Inverter III with following Advantageous
1.the 2012&first generation's case is iron,the 2013&second adopt aluminum case,the hardness and strength of 2015&third are much higher than the first, the third version, we add the 3.5" LCD meter in the inverter. from the meter, user can know the situation of inverter, for example, ac output, ac watts, ac amps, it can calculate electricity cost / total consumption power / the total working time. it's a smart inverter. the machine has three functions, inverter/charger/UPS, an inverter can offer your all request.
2.Heavy load appliances can connect together ,but make sure not over w.
this is a inverter which has transditional transformer, the transformer is made by a wide copper. in our company, we call it low frequency power inverter. it's different with the inverter which made by mosfet(we called high frequency). some device which has big motor, pump, compressor and conditioner, they have large surge power when turn on, it need 10-15 times power to supply. at this time, the high frequency(HF inverter) has limit ability for running these devices, it only can run some small watts device. when run the large watts device, it easy to damage the mosfet. at this time, the low frequency show its value, it can run very easy. usually, 3000w HF is 7-8kg, but the 3000w LF inverter is about 20kg, that why the inverter can handle the large watts device. the inverter has inverter/charger/ups functions, it's a smart inverter.
when you want to run fridge, pump, compressor, microwave and so on, please check with your seller first, whether it can run it, don't buy the wrong inverter, spend your money correctly. follow our warning label to use, it will have no problem.
3.If you only connect battery with load, ac cable unconnected, when you switch to battery charger mode, this means 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 3 sec., the inverter will detection itself, after the 3 sec., amp will go to 3 amp (stand by power, time: 1 sec., 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)
4.If customer needs to use refrigerator, can switch the mode to power save on, as refrigerator only will work every half an hour or one hour , but inverter stay in power save function, no load current is 0 amp, will save power.
5.When you need plug in the ac power cable to charge your battery, you need turn off the switch, after plug in, then switch on, when you need plug out the ac power cord, you also need turn off the switch, the remove the power cable, other wise when you plug in or out the ac power cord, will have voltage spark come to damage the inverter, tks for your attention.
6.For UPS Function: usually UPS function is build-in battery, only can run about 5 mins. However, this inverter can decide how long you want to use, the higher capacity battery you connect, the longer time you can use. Just connect the AC power cord to your home AC source, when out of AC power, the inverter will auto switch to inverter function, this can be your back power.
