Hello sir, is it safe to connect laptop, small lcd tv, or cell phone charger? I plan to build a portable solar battery with built in AC inverter, but as this says 20khz frequency, I'm afraid, because usually devices run 220v 50Hz in my country. It was cheap to get one of this instead of a "ready" inverter and disassembly to mount on custom case. Thank you very much
@@ahlidap We tried it to charge a phone, it worked. I wouldn't want to try it powering a laptop or a LCD tv. I use this version to power a heat pad, it works very efficiently without overheating. The heated (120w) get very hot indeed.
Bought one of these, money very well spent. This inverter (150w) may be 20kHz but it powers a 120w electric blanket really efficiently till the battery eventually goes flat without any overheating or burning out. For me recommended.
(For use with a switching power supply) I think you might have to use a high frequency diode in order to not burn it out. Can you please show how to do that?
Inverter is 20khz. Must use small analog multi meter with face and needle . 2 terminals jumped with solder on board, then put switch in red wire line. If output terminals changed from AC to DC, high frequency, fast recovery diodes must be used. 1- half wave DC or 4 -as bridge rectifier. Put fuse in battery line to switch. Measure volts over output resistor, or use light bulb.
Square wave 20Khz AC supply output needs matching transformer hand wound of Impedance source to load resistance. There is 50% voltage loss, so as needing twice voltage to begin with. The intermediate transformer can be a step down type as well as being an isolation transformer so as 2 grounds won't interfere with each other for 2 power sources same time. Reactance formula for coil secondary of inverter is same as Impedance value. Can also multiply numbers to get whole numbers for same ratio for the matching transformer without a fraction. Check also the general transformer formula for Bsat of core , so as the numbers selected allow for Bsat ferrite between (1200-2000), so as no shorting of your circuit. example- 1.75 to 1 as 21turns to 12 turns step down. 60v to 30v. matching ratio is square root of impedance ratio. LC meter and calculator would be needed. Straight AC square wave power does not like inductive loads. You Can change power supply to full DC.
На выходе таких штук с алиэкспресса импульсное напряжение высокой частоты, его не видит мультиметр и показывает неверные значения в 500, а то и 1000В. Нужно использовать осциллограф для замеров.
Ok i got one . this little beast work just For light . for bulp light led Work ok . light bulp 40 watt Not enough but is light it . i will try for Do a uptade of test

hello can i use it with solar panel to run few bulbs during the day

thank you so much
I didn't see in the tester reading 220 or 110v. How you do that?
Hello I have bought a similar one but of 1000W . What is the maximum ampere rating for my inverter module can you please tell me
Hallo, kann man 2 Stück gleiche 150w Inverter parallel anschließen, so das man 300watt am Ausgang hat?
hi, how to change frequency kit to 50hz ?
hello sir can i use it directly with big solar panel?

Can it be used for ac motors (low power swing motors used in incubators) ? ?
Can it be used to Run my Laptop?
What the name or link the tool did yonuse for frequency metering that?
Can it drive LED or pcl light bulb?

What is the voltage that is measured using a red multitester?

Can we use this for mobile chargers
Is there any way this can be modified to run off a 24v supply?
Input voltage: DC12V or DC-DC Step Down Buck Converter to 12v
I want to buy it. But where available it and how to buy it. Please tell me

Price....where you get the board
bit.ly/3KE8Deg
why is the ampere consumption at 7.2ah at 220 volts? It's very high!! 😵💫😵💫😵💫
Very good video thank you
How much is this sir?
does it provide a three phase output??
No is just a step up transformer only with one common terminal and one terminal for 110v to 220v output👍
Can i use 60w soldering iron with 150 inventer ?
ill tast it after 1 month and ill answer you
