I have a system on my boat with two Multiplus systems that provide 240v to my inverter panel. I also have a couple of MPPT 100/50's that charge the batteries. PowerAssist works great when I limit the incoming power on the Multiplus, but what I'd like to do is to use all available solar power in place of the grid power when its available. Currently, once the batteries are topped off, the MPPTs back off because the batteries are charged, the Multiplus is using 100% grid power. How can I use that unused solar capacity and fill in the rest with the grid power?
