Not an easy item to install or program. It works great. Do not skimp on quality cable and line. Read all reviews. There ar some great nuggets in there. Read the instructions several times. Adjust the programming to fit your batteries and panels. It can be very frustrating if you don’t understand what values to insert. Do not tie in to the breaker box unless you absolutely know what you are doing. This item is fantastic and works well but take your time.

The LCD is easy to read and understand. LEDs are easy to see, and the included book includes all the register values and defaults. You'll probably only need to change two to four of the values, like battery type and charging behavior.

Basically perfect for a boat or small house solar. The 8k inverter is enough to run a 1500 watt heat gun and still run my tv and fridge. I use lifepo4 batteries and charge up to 5kw at a time, this charger will charge up to a little more than a kWh ber hour from utility power. I also use a pigtail to charge from a generator through my shore power connection. Your charging from solar will depend on your output of course. Unit is quiet at low to moderate loads and even with the fans on it not very loud.
