Bests & Worsts Reviews from Amazon

Let's begin with I am a retired electrical engineer and I purchased this unit in August of 2017 for use on a 5kw photovoltaic array in michigan. I will spare readers of the detail of owning this unit. However, stay away at all costs. Arguementive customer service refused to consider the unit was faulty and refused return. Too small of wiring for a.c. input eventually melted terminal strip, luckily found before fire. Internal wiring should have been 10 gauge for advertised wattages. Long story shortened, it's a toy and don't waste your time or money. After only less than a year I replaced with a magnum hybrid inverter...made in USA. Although almost twice as costly, it it superior as far as flexibility, reliability and most importantly, unlimited customer service. Get the remote and it's incredible. Spend the extra money and avoid a potential call to the fire department. It is my opinion that Amazon stop selling this brand manufactured overseas. If I could give it zero stars I would.
