This is a great all in one inverter. I purchased this to replace a 4K 24 volt system and have been very pleased with the performance, having 2 PV inputs is great, as I have 2 arrays at different outputs. This is a very customizable inverter with many menu settings, I've had to contact customer service to help me chose the right settings and they were very responsive, same day replies. This inverter has been running 24/7 for the past 7 months with no problems.
