Two options: 1. AC couple existing inverter to a battery capable inverter.
2. Replace existing inverter. I favor option 2. Option 1 is only preferred if gaining access to the existing inverter for replacement is difficult. An example would be a micro-inverter system. New AIO inverters allow true high voltage PV input so the existing stringing will probably not need to be modified. I’m new to this so type of upgrade so I welcome any corrections to these opinions. I did replace a Sunny Boy in my shop with a Soul Ark and it’s working great!
