Powerhorse 7500I Review. I would prefer an inverter generator as they seem to be quieter and safer for electronics. This video shows the powerhouse 7500i generator in use and goes in depth of its real world application on a food trailer especially . The noise level from initial reviews seem to be very low. Maybe you can be the first on the forum to review one. Is this an okay option as a powerful inverter generator? Our powerhorse 7500i wireless remote control kit is the most easily installed generator remote on the market. This powerhorse inverter generator provides more power with less noise, plus low 1.5% total harmonic distortion for safely running sensitive .
