Tres bon produit je vous le conseille . Je fait tourner dessue télé barre de son et caisson bass en meme temps. Je fait aller air frayer micro ondes aucun souci aucun bruit

I bought this because it was difficult to find a reasonable prices 24V sine wave inverter for ~2 kW. This 3 kW unit is too powerful for my current 100Ah 24V lithium battery, but seems to be ok, probably ok if not using the full power. I have not used it much. It is very silent at lower < 1kW loads, although longer use may ramp up the fans. My previous experience with smaller < 1kW inverters is that they can be very noisy, so this has been surprisingly silent. I think it came with a bag of fuses, as shown in picture, I could not figure out where these are supposed to be put, maybe they are spares and go inside the unit or something. The USB port is for remote display, if you try to charge your phone with it, it might break something. Vacuum cleaner works ok with this inverter.
