I have an EasySolar 48/3000/35 on a vessel which has Panels & Shore Power connected, which charges a couple of 48v batteries which is used to provide 240v at sea. Being an American-made boat, how can I connect an Auto Transformer and convert 240v to 120v just for some specific 120v loads.
do I need to connect the ground relay control between the EasySolar and the Autotransformer.
