Adding optimizers to off grid system with mppt charge controller.

I have installed several off grid systems on boats. These systems consist of 3 to 4 250 watt panels connected to a mppt charge comtroller. All the systems suffer to some extent from shading. I am trying to design a system using panel mounted optimizers in order to improve overall production. Can dc optimizers be added between solar panels and mppt charge controller. I don't know how the mppt charge controller will behave with 4 optimized panels feeding it.

Hi Shay, Welcome to the Forum.
You are asking a good question. In general, it is a very good idea to contact the Charge Controller (CC) manufacturer for guidance. Some Optimizers can damage some CCs, as I read it.
As you know, if it is possible, try to run individual PVs in parallel to help reduce the power losses from shading.
FWIW, Vic
