The grid tie inverter can sell through the Magnum relay. When the grid
goes down, it will feed the batteries.

Hi All,
I've got someone who wants to tie their off-grid system with a Magnum inverter (which I think is a 4024 PAE inverter) to the grid. Since the Magnum inverter cannot be grid tied, I was wondering if there is some kind of simple grid tie inverter that can be the grid interface, while keeping the existing system in tact.
Otherwise, I see two paths here. The less expensive path would be to ditch the batteries and connect the panels to a grid tie inverter. Otherwise it seems that we will need to get another battery based inverter that is meant to be grid connected to replace the Magnum.
Cheers,
Dave
