The MATE3 System Display and Controller make it easier than ever to program and monitor a complete OutBack Power system. An intuitive user interface and integrated system configuration wizard make system setup and programming quick and seamless. The ability to set unique multi-level user passwords makes it possible to secure critical system settings from unintended changes while still allowing open access to necessary functions. Other features making system management simpler include an easy-to-read graphical backlit LCD display, improved tactile buttons, and user programmable “favorite” keys for immediate access to the most wanted features. An intuitive scroll wheel interface allows easy adjustment of system set points. Expandable SD card memory increases data-logging capacity as well as making it easy to upgrade units in the field. A built-in clock and calendar function enables timer-based programming of inverter and charger operation. This setting allows the system to work with time-of-day power rates or to limit a generator’s runtime to a specific time period of the day or week. All settings are stored in onboard memory to eliminate the need to reprogram in the event of a system shutdown or battery replacement. The MATE3 supports web-server access via an intranet to allow monitoring of an OutBack system.
