I have a trace inverter DR 1512, I am having a problem with my system, which includes a 5000 watt gen, and solar power. When I am dry docked and have solar, system functions fine, when I lose solar and go to battieries it appears that i have low power, just as if no charge has reached batt. Solar panels producing good pwr, regulator operating properly.

How old are your batteries?

The solar panel is just to charge your inverter,if it is charging and the inverter is on it will drain the current the solar panel is supplying to the batteries,this makes it look like it is not charging ,so i advice you to switch off you inverter when charging it,get another set of batteries connected to your solar panel then charge both, let them be separated so that the new one is not in use so that when solar is out you can switch to the other set of batteries
