PC Meterbus Adapter (MSC)


Morningstar's PC Meterbus Adapter (MSC) converts a controller's meter port (RJ-11 phone type connector) to a standard RS-232 serial connector for connection to a PC or other equipment. The MSC may be used with any Morningstar controller or inverter equipped with a meter connection that does not also already have a RS-232 port.

By converting to RS-232, the MSC allows Morningstar's controllers and inverters to communicate with a variety of third party serial enabled devices such as:

  • A PC running Morningstar's MS View software or any other compatible software.
  • A serial enabled device such as an internet gateway.
  • Another MODBUS enabled hardware device at the site that needs to access solar system information.
Establishing a communications link enables the monitoring or logging of data from the controller or inverter as well as the customizing of any user-adjustable settings. The MSC makes available a wide variety of data stored in Morningstar's products such as (varies by product):
  • Battery Voltage (including minimum and maximum)
  • Solar charge current to the battery
  • Load current from the battery
  • Accumulated solar and load amp hours
  • Charge Stage
  • Errors and alarms
  • Local and battery temperature
  • Data logging files
All data is transmitted in the form of MODBUS protocol. This industry standard was chosen for a high level of compatibility with a variety of equipment. Each Morningstar product has its own data specification.

The MSC is sold as a kit that includes the following: PC Meterbus Adapter, RS-232 cable with connectors: 1.8 meters (5.9 feet), RJ-11 cable with connectors: 1 meter (3.3 feet)

WARRANTY: 5 years
