Inversor CHANGI 4000W, Forma de Onda e Review (Parte 1)

In this video, you will see a very good cost-benefit voltage inverter that I brought from China. It is the CHANGI 4000w Inverter with 24 volts DC input and 110 volts AC output. 📌Use this BGESD20 discount coupon on your purchase at the link below 🚩Link to purchase the CHANGI Inverter: https://s.click.aliexpress.com/e/_97HUCH ☀ OffGrid Solar Energy Course - Plan a Successful OffGrid!

This inverter has a nominal power of 2000 watts and a peak power of 4000 watts, but there are other versions from 3000 watts peak to 6000 watts peak. Both are advertised with their peak power, but the nominal power is half the peak power, for example: the 4000 watts peak has a nominal power of 2000 watts, and the 6000 watts peak has a nominal power of 3000 watts. In this video, I will show the waveform of this off-grid voltage inverter, as well as do a complete review showing each of its stages and indicating good points and not so good points. In this way, I believe I can help you make a decision when making a purchase. This inverter was imported via Banggood and took approximately 40 days to arrive in my hands. I was taxed 60% of the price paid for the inverter, but I still consider it a good investment. However, it is important to make it clear that if you decide to import this inverter as well, you must bear in mind that you are responsible for any problems that may arise, whether they are problems with the import or with the inverter itself. If you are still undecided, I invite you to watch the series of videos of inverter tests and reviews that are available in the links below.    • Teste de Fogo em Inversores OffGrid • Temp...   TSM inverter tests:    • Testes Inversor TSM   Become a member of this channel and get benefits:    / @eduardoaquino   #EduardoAquino #inversoroffgrid #EnergiaSolar -- Telegram Group -- Join the Official Telegram Group and receive exclusive content 📢https://hotm.art/CanalTelegramEduardo... 🚩 DON'T CLICK HERE: https://bit.ly/naoclikaraqui 📚 GET TO KNOW MY COURSES ▶ Take the Solar Energy Course now: http://bit.ly/Curso-Energia-Solar-Edu... ▶ Purchase your Sinusoidal Inverter Project at this link: http://bit.ly/Projeto-InversorSenoida...
