I installed this inverter charger on my boat. Within four months one of the internal wires to the terminal block must have worked itself loose. The terminal block melted and, had I not noticed the smell, would likely have caused a fire. AIMS customer support was no help. After fixing the problem, I reinstalled the inverter.
After just over a year of use the inverter failed for good. It would no longer turn on and would immediately emit a constant alarm sound. While the inverter was great when it worked, I cannot recommend the product due to safety concerns.
I should also note that my buddy bought a 4,000W model after seeing mine. His failed within months as well.
