Morningstar MRC-1 Meterbus to EIA-485 Adapter

Morningstar MRC-1 Meterbus to EIA-485 Adapter

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 and TriStar MPPT controllers. The MRC-1 can also be used for EIA-485 communications with any 3rd party hardware that supports Modbus communication.

Key Features and Benefits

• The MRC-1 is protected against reverse polarity at its EIA-485 power terminals
• The MRC-1 supports a four wire EIA-485 bus: GND, Data A, Data B, Power. A networked GenStar MPPT will use only three (3) wires: GND, Data A, Data B. Data A and B are differentially driven lines that carry the network data
• The MRC-1is capable of supplying isolated power to an EIA-485 network, eliminating the need for an external bus power source in many cases
• Five year limited warranty

Other brands survive harsh conditions. Morningstar thrives in them.

With more than 25 years of experience and well over four million products in over 100 countries – most of them still in operation – Morningstar has truly earned its reputation for building the “world’s leading solar controllers.” At Morningstar, the word “reliability” means a lot more than a marketing adjective. Morningstar’s employee-owned culture works hard to maintain the lowest hardware failure rate in the industry, because our own reputations literally ship with every product.

That’s why system designers of the most mission-critical solar energy installations around the world insist on Morningstar components, and why you should too on your next project. From mineral mines in South America to telecom repeater stations in Canada, from gas wells in the Middle East to mountain peaks in Nepal, Morningstar technology and legendary quality make the difference between success and failure – and make renewable energy a practical, cost-effective, and long-term solution.
