I've been using this inverter for many months & it has always worked perfectly so far, silent, powerful, & reliable. The included voltmeter however is not very accurate, it shows around 0,6V more than the real voltage, but for me it's okay , once I know the difference to take into consideration it doesn't bother. I must also say I didn't push it to the extreem limits & have always used it quite gently, below 1kw, as that was my intension before even buying it. I did never burn the fuses, not even once, I am using a 100A external fuse and an external circuit breaker as well of 80A that cuts the current automatically as you go around 1kw ( or above obviously ). It is not noisy, it doesn't heat, it works fine, it gives enough power at peaks ( motors startup for instance ), the price is fair, the display is nice ( better if it did turn off automatically if unused ), the delivery was okay. Now I just hope it keeps working the same way for a long period, if it will then it is really an excellent product, providing one uses it properly ( if you pretend to get the highest possible power out of it, worse if for a long duration, then you will most probably have problems ).
