Morningstar > ReadyBlock Relay add-on for GenStar MPPT Charge Controllers

Add advanced load control and signaling functionality to any compatible system

• Easily add features and functionality
• Dry contacts control
• Alarm conditions signaling
• Smart Load control
• No need for external wiring
• Reduced field down-time

Morningstar’s ReadyRelay is part of the ReadyBlock suite of add-on-- yet built-in-- functionality available in Morningstar “host” components featuring the ReadyRail expansion system. “Add-on” in the sense that ReadyBlocks can be integrated into a system at any time, either on inception or later as needs arise. “Built in” because once added, ReadyBlocks become part of the host component, seamlessly integrated into both its hardware and software.

No additional configuration or connections are required. ReadyBlocks automatically activate and are recognized, and are ready to go, immediately after being snapped into a ReadyRail.

Key Features

• Achieve tighter control over the energy balancing in a system, through smart logic and prioritizing loads for load-shedding
• Initiate dry-contact signaling and monitor alarm conditions based on precise parameters. ReadyRelays may be toggled by user-defined logic, using real-time information including clock and calendar
• Reduced field down-time and simplified servicing and maintenance. ReadyRelays are individually replaceable without removing a block from service—quickly and easily, in conditions where space is very tight (such as in enclosures)
• Eliminates the need to specify and source individual relays, especially in lower power applications, with two high-quality relays provided per ReadyBlock. Along with that, the need for external wiring and costly relay terminal blocks is also eliminated

Key Features and Benefits of ReadyBlock add-ons for GenStar MPPT Charge Controllers

• ReadyBlock expansion system through exclusive ReadyRail design achieves true controller technology integration. All information is instantly available since it’s actually part of the hardware and software of the charge controller itself, instead of outside the system as with a typical stand-alone accessory device. Available ReadyBlock modules include:
  • ReadyShunt - battery metering/monitoring, key metrics including SOC, energy in/out (Amp hours), current measurement for system sources and loads, and more
  • ReadyBMS - full communications and control with lithium batteries
  • ReadyRelay - signaling (dry contact), advanced load control
• Full network integration without requiring adapters or extra equipment– Modbus and ModbusIP via 485, Ethernet, WiFi, MS-CAN connects MS Devices (proprietary), GS network information bridging.
• WiFi, and Bluetooth connectivity for a (future) mobile device and app for easy connection, dashboard views, downloading data, and firmware updates. It also includes our LiveView 2.0 web app interface onboard
• Powerful Load Control – built-in 30A load capability, unique for controllers in this power class
• Oversized PV Array Input capability – array input power rating @ 150% meets today’s system design needs for PV oversizing
• Extensive electronic protections include cold-weather lithium “fold back” circuitry to guard against cold-weather charging damage. Also, short-circuit, over-current and reverse polarity to ensure the controller will not be damaged by wiring mistakes or overloads
• Fanless design for improved efficiency and exceptional long-term reliability
