The Digital Multi Control Panel GX allows you to remotely turn the unit on and off. You can control the input current. It also has LED system indicators for both the charger and inverter. It is the same as the previous version, but with a new design. An extra advantage of this panel is the easy mounting: the included mounting frame allows the user to mount the panel from either front or back side. Due to the mounting frame, the mounting holes will no longer be in sight. The body of the GX panel is made of plastic, which makes the panel lighter and adds a modern look to the panel.
