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

Manufacturer Part Number: RB-BMS

The solution for building “lithium DNA” into any compatible system—now or later

• Provides communication with lithium batteries
• Enables “closed-loop” charging control
• Delivers integrated battery BMS data
• No need for additional configuration or connections

Morningstar’s ReadyBMS 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, are recognized, and are ready to go immediately after being snapped into a ReadyRail.

Key Features

• Total peace of mind during operation, with a charger and battery working in unison as a system
• Closed loop, so no need to specify charge algorithm parameters. ReadyBMS “gets it right” first time and every time
• Powerful information for decision-making. Users can specify automated actions in their system based on detailed battery information, with BMS data made available for use in logic configuration
• No need for external additional widgets and accessories, including Remote Temperature Sensors and Battery Sensors. ReadyBMS gets charging commands directly from the battery that are already temperature compensated, along with battery voltage reporting eliminating the need to account for voltage drop across conductors. This reduces system set-up time and complexity, reducing costs and also eliminating potential common failure points (for example, system fault if an RTS becomes disconnected)
• Highly accurate, responsive performance. With Ready BMS the charger gets precise battery data without the need for external measurements, and can respond in real-time to the needs and limitations of the battery in real-time, ensuring optimal charging while not exceeding limits

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
