SAFETY INFORMATION

WARNING: Shock Hazard
The Morningstar ReadyBMS must be installed by a qualified technician in accordance with the electrical regulations of the location of installation.

WARNING: Shock Hazard
Disconnect all power sources to the host and all other connected devices before installing or removing ReadyBMS. Do not install or remove ReadyBMS when the host device is powered ON.

WARNINGS: Shock Hazards

• Read all the instructions and cautions in the manual before starting the installation.
• There are no user serviceable parts in the BMS Block. Do not disassemble or attempt to repair.

GENERAL INFORMATION

Terminology
The product ReadyBMS will be referred to as such, or BMS Block. In contrast, the separate battery management system will be referred to as the BMS, battery, or BMS-battery.

Overview
The Morningstar ReadyBMS provides simple visibility of battery performance, hands-free settings and optimized battery control. The ReadyBMS will report any data variable contained by BMS-battery. ReadyBMS will support batteries in parallel depending on the capability of any approved battery model. Use requirements:

• The ReadyBMS requires a Morningstar ReadyRailTM-enabled host device,
  e. g., GenStar controller or ReadyEdge Communications Center to provide a mounting surface, power, and programming capability.

• Morningstar integrated and approved battery models

• Currently updated BMS-battery firmware

Compatible Batteries (CANBus-enabled batteries)
All initially supported batteries conform to CAN pin configuration. For a current list of battery storage products supported by the ReadyBMS, go to www.morningstarcorp.com.

Features

Limitations
Only one BMS Block is supported per system. If multiple BMS Blocks are present, a system alarm will trigger and a local display or LiveView webpage status message will indicate which of the BMS Blocks is active for collecting data from a BMS.

FURTHER:

• When using a BMS Block, only a single battery (or a bank of parallel batteries) is supported in a network of host controllers. A parallel bank is viewed by BMS as one battery.
• When using a BMS Block, only a single manufacturer of batteries is supported. If the battery/bank is changed to a new manufacturer, the host device-BMS Block needs to be re-commissioned.
• When using a BMS Block, only a single battery model is supported. If a network of parallel batteries is employed, to work properly with the BMS Block, all of the batteries must be the same model.

INSTALLATION

Morningstar Ready Blocks (ReadyShunt, ReadyRelay, ReadyBMS) are DIN rail- mounted, and have modular 20-pin connectors on each side of the Block. The left-side male connector mates with the host device’s control board, while the right-side female connector is available to mate to another ReadyBlock (daisy- chain configuration – see Figure 3-1 below). Each ReadyBlock takes one of (3) positions on the GenStar DIN Rail – the left-most being Position 1.

WARNING: Shock Hazard
Disconnect all power sources to the host and all other connected devices before installing the ReadyBMS. Do not install or remove a ReadyShunt while the host device is powered ON.

NOTE: Only one BMS Block can be active in a system at one time. If more than one BMS Block in installed, the one in the lower slot number is activated, and the other(s) are deactivated.

Mounting
The ReadyBMS is a modular accessory designed for installation onto a DIN rail. Though there are spaces for three (3) Ready Blocks on a GenStar host device DIN rail, only one (1) ReadyBMS can be used per system.

To install a ReadyBMS (see Figure 3-1 below):

1. Power OFF host device. If applicable, remove Block cover and cut slot(s) for Block(s)
2. Pull yellow tab out
3. Fit Block slot downward onto DIN Rail
4. Slide the Block to the left, but before joining the male and female mates, be sure that pin guards and pins are lined up correctly. Carefully slide the Block farther to the left to securely join the Block pins with host-device female mates.
5. Push yellow tab in, to secure Block on rail
6. Secure Block(s) to DIN Rail with cover, clamp, or other means provided with host device.

Connections
For CANBus-enabled batteries, use an 8-conductor straight-through RJ-45 cable (provided), and attach one end to one of the RJ-45 ports on the BMS Block – see Figure 2-1. Attach the other end to a CANBus port on the BMS-battery. All supported batteries conform to CAN pin configuration – for details, see Table 3-1 and Figure 3-2 in Section 3.3.

• NOTE 1: If the BMS Block is used with the only controller in the system, or it is at the end of a CANBus Network, the BMS Block CANBus-RJ-45 port not connected to the BMS-battery will require installation of a terminator plug (120 Ohm terminator resistor installed across the CANL and CANH wires). A BMS Block communications terminator plug is included – see Figure 2-1 in Features Section 2.4. For any BMS-battery side CANBus termination requirement, refer to your third-party BMS-battery manufacturer’s documentation.
• NOTE 2: For parallel battery configurations, refer to the BMS-battery manufacturer’s documentation on how to connect the battery bank to the BMS Block.

CANBus-enabled Batteries
All currently supported batteries conform to CAN pin configuration. For an up to date list of battery storage products supported by the ReadyBMS, go to www.morningstarcorp.com. CANBus-enabled batteries will require a cable assembly with the configuration seen in the Table 3-1 and Figure 3-2 below. Some BMS-battery systems may require a modified cable assembly – available separately.

Table 3-1. CANBus Protocol Battery Cabling Pin-out

CONFIGURATION

General

• First connect the battery to the host device to power the host device-BMS system.

• The BMS Block is configured via the local meter display during commissioning of the host device, e.g., GenStar MPPT.
  Commission the host device with a compatible BMS-battery system assignment. This is the only required configuration setting; but a BMS LVD-LVR Profile can also be configured during commissioning.

• The BMS Block will automatically receive and configure all external BMS-battery charging parameters.

Configuration Access-Changes
After commissioning, access and changes to MS battery type must be done on the local meter display with a factory reset (re-commissioning).
Navigate to:
Commands\System\Reset to Factory Settings

LiveView Webpage
BMS Block DIN rail position and status can be viewed in the Morningstar LiveView Webpage – liveView Screen. Use one of the following methods to access LiveView:
With the host device connected to a PC, open a Web browser, and either:

• A) Enter the host device IP address into the address bar, e.g., http://192.168.1.253.
  The IP address can be found in the meter display in Settings\Network.
  OR,

• B) Enter the host device NetBIOS name [product abbreviation + 8-digit serial no.] into the address bar, e.g., http://GS21320850. The NetBIOS name can be found in the meter display in Settings\Network.

OPERATION

Mode of Operation
The BMS Block operates only in a Normal Mode that decodes data from a battery’s BMS interface and conveys it to the host device.

Web Monitoring Support – LiveView
LiveView is the default Web Page that displays basic real-time system data, faults and alarms. See Section 4.3 for details.

LED Indications
See Figure 2-1 in Features Section 2.4, and Table 5-1 below.

If a BMS Block is required per host configuration, the following host device faults will be triggered, and will cause the host device to cease operation:

• BMS Block Removed – if the host is configured to use a battery that requires BMS communication, and a BMS Block is not connected to the Ready Rail (BlockBus), this fault will be present until a BMS Block is connected.
• BMS Lost Communication – if for any reason a BMS Block is present, and communication with a battery is lost, this fault will be present until communication is re-established.

BMS faults will appear in the host device general faults and alarms directories of the local display and LiveView web page.

Firmware Updates
A BMS Block connected to the host device will automatically have its firmware updated with the host’s BMS Block firmware version. For the latest battery support and features, ensure that the host device has been updated with the most current host device product firmware.
