Morningstar MRC-1 MeterBus to EIA-485 Adapter

The Morningstar MRC-1 converts a controller or inverter's RJ-11 MeterBus interface into a standard EIA-485 serial connection. This allows MeterBus-only Morningstar controllers to integrate seamlessly into EIA-485 MODBUS networks, SCADA control systems, or multi-device setups alongside controllers like the GenStar and TriStar MPPT without requiring intermediate RS-232 conversion stages.
