I love my inverter. It has been operational since May 2018. Very easy to install. The instructions are clear. You have to connect the battery directly to the inverter and they feed the double cables. The only moving part is the fan, which only spins occasionally, so it can be installed anywhere (in any orientation) to eliminate vibration and heat sources. If your mounting style causes the logo to be upside down, simply remove the cover and turn it over. Works anyway! I power the satellite dish, receiver, TV and soundbar. I have two 6v golf cart solar panels that run all day and late at night from this inverter. I like the silence with no generators running! You won't find a better pure sine wave inverter at this price point.
