Morningstar PC MeterBus Adapter

Manufacturer Part Number: 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)
