Did alot of research before buying this Charger/Inverter. Was looking for a good high quality unit for my Hunter 420. The prosine 2.0 fit the bill. We were watching a movie this past weekend and right in the middle we lost shore power and it was 5 minutes before we knew it. I noticed the heat pump had stopped and the movie had never even flickered. Power came back on about 20 minutes later and my inverter returned to charging the house bank. I could go on but I'll just say, perfect. Also, Hodges Marine had the best price hands down and fast service too. What a perect deal all around.
