Magnum's MagWeb allows for remote monitoring of Magnum inverters and accessories. A ME-RC or ME-ARC system controller is required if you want to monitor your batteries or automatic generator start module. No controller is necessary if you plan to monitor the inverter only. The MagWeb monitor sends system information to the Magnum website that is accessible anywhere with an internet connection. MagWeb will monitor your system status, program settings, faults, DC volts, DC amps, tech. menus, battery monitor status and auto generator start status.
