  1. Excell Berryhill

    I would like to say this is the easiest inverter I have installed, it is so quiet and their is very few wires to use. I would recommend buying from Practical Preppers and watch his youtube channel Engineer775. The manual is easy to read and the wire diagrams were very helpful. This inverter is powering about 65% of my home and is tried into the grid. I have 28 panels that produce close to 12,460 watts. I’m not selling back power to the grid because I’m using every Watt I produce. I still have more room in the SOL-ARK15 to add more panels and bring my production up to 80%. I bought inverter because I wanted to reduce my need on grid power. Lori was a great help in customer service with my questions.

    They were very helpful with information. I was initially looking at the 12 K Solark, but it only had a 60 amp grid power pass-through. I ended up going with the 15 K because it has a 200 amp grid power pass through. practical preppers also had one of the best prices on the Internet. I would highly recommend working with them. Shipping was very fast.
