Morningstar recently launched a new Meterbus to EIA-485 Adapter (MRC-1). The Meterbus-485 Adapter (Model: MRC-1), with RJ-11 cable included, converts the Morningstar MeterBus RJ-11 electrical interface to a standard EIA-485 interface. This allows Morningstar controllers or inverters with a MeterbusTM port, but without an EIA-485 communications port, to network with Morningstar EIA-485 devices like the GenStar MPPT and TriStar MPPT controllers. The MRC-1 can also be used for EIA-485 communications with any 3rd party hardware that supports Modbus communication. This accessory features the following benefits:
- Protection against reverse polarity at its EIA-485 power terminals
- Support for a four wire EIA-485 bus: GND, Data A, Data B, and Power
- Supplies isolated power to an EIA-485 network, eliminating the need to an external bus power source in many cases
- Five year limited warranty
The MRC-1 is compatible with ProStar MPPT and PWM controllers, SunSaver MPPT controller, SunSaver Duo Controller, and SureSine Classic inverter. The Meterbus to EIA-485 Adapter is in stock and ready to ship from our Los Angeles and Taiwan warehouses.
