- | + | ||
- | This manual is intended to be used in conjunction with the product manual supplied by Pylontech. It provides additional and specific information regarding integration with Victron systems. | + | |
- | + | ||
- | The Pylontech includes a Battery Management System (BMS) with each battery cell module. This interfaces with the Victron [[venus-os: | + | |

- | === 1.1 Offgrid, Backup and Energy Storage Systems are possible === | + | |
- | + | ||
- | Victron + Pylontech can be used for the following system types: | + | |
- | + | ||
- | * Energy Storage Systems - Self Consumption ([[ess: | + | |
- | * Grid Backup | + | |
- | * Off-grid | + | |
- | + | ||

- | + | ||
- | In grid connected systems, advanced control functions are configurable in the ESS settings on the [[venus-os: | + | |
- | + | ||
- | In off-grid systems, the control functions of the Pylontech Battery Management System (BMS) are built into the latest version of the [[venus-os:start|Venus-device]]. | + | |
- | + | ||
- | === 1.3 All 48V Multi, MultiPlus, MultiGrid and Quattro are compatible === | + | |
- | + | ||
- | The minimum firmware version is 422. Though updating to the latest firmware is recommended where possible. | + | |

- | + | ||
- | === 1.4 All 48V VE.direct BlueSolar and SmartSolar MPPT Chargers are compatible === | + | |
- | + | ||
- | For proper operation, the Pylontech battery needs to be able to control the charge current. Therefor it is recommended to use Victron 48V compatible MPPTs models with VE.Direct port for charging. | + | |
- | + | ||
- | __MPPTs with a VE.Direct port__ | + | |
- | + | ||
- | MPPTs are controlled via the [[venus-os: | + | |
- | + | ||
- | The MPPT requires connection to the [[venus-os: | + | |
- | To test operation, try disconnecting the [[venus-os: | + | |
- | + | ||
- | __MPPTs with a VE.Can port__ | + | |
- | + | ||
- | Use of VE.Can MPPT's with Pylontech batteries is not supported or documented. | + | |
- | + | ||
- | + | ||
- | ==== 1.6 Minimum Battery Sizing Recommendations | + | |
- | + | ||
- | Each US2000B Plus battery module is approximately 50Ah at 48V, can provide 25A continuous charge and discharge and 100A peak for 1 minute. | + | |
- | + | ||
- | The charge and discharge rates are managed automatically by the Pylontech battery and [[venus-os: | + | |
- | + | ||
- | Using very large solar arrays with battery banks that are too small can exceed the limits of the batteries ability to charge and possibly lead to the BMS triggering over-current alarms. | + | |
- | + | ||
- | You must have the minimum number of units to supply the potential current demand of the load connected to the inverter. It is more desirable to have the inverter/ | + | |

- | ==== 2. Wiring of CAN-bus cable between B-Box and Venus-device ==== | + | |
- | + | ||
- | Use the //VE.Can to CAN-bus BMS type B Cable//, part number ASS030720018. Plug the side which is labeled Battery BMS into the Pylontech CAN port. Plug the side labeled Victron VE.Can into the [[venus-os: | + | |
- | + | ||
- | Then, plug a [[https:// | + | |
- | + | ||
- | More information about the cable can be found in [[battery_compatibility: | + | |
- | + | ||
- | Without properly connecting this cable, the battery will not show up on the display of the [[venus-os: | + | |
- | + | ||
- | It is important to ensure this connection and display of the battery on the [[venus-os: | + | |

- | + | ||
- | + | ||
- | === Option A: ESS Assistant === | + | |

- | === Hardware Protection Points === | + | |
- | + | ||
- | In normal operation, the charge parameter limits are set by the Pylontech battery and communicated through the system by the [[venus-os: | + | |
- | + | ||
- | * Low Voltage: When the battery discharges to 44.5V or less, battery protection will turn on. | + | |
- | * High Voltage: If charging voltage above 54V, battery protection will turn on. | + | |
- | * Working discharge temperature range is from -10 to 50 degrees celsius. | + | |
- | * Charging temperature range is from 0 to 50 degrees celsius. | + | |
- | + | ||
- | If operation is attempted outside the operating range, the battery will disconnect to protect itself. | + | |
- | + | ||
- | ==== 5. Venus-device Configuration ==== | + | |
- | + | ||
- | * Select the //CAN-bus BMS (500 kbit/s)// CAN-profile in the CCGX. Menu path: //Settings -> Services -> CAN-profile// | + | |
- | + | ||
- | * After properly wiring and setting up, the Pylontech will be visible as a battery in the device list: | + | |
- | {{ : | + | |
- | (if you have multiple batteries a single entry will show up, which represents all batteries). | + | |
- | + | ||
- | * The parameters option within the battery page shows the actual battery charge and discharge limits | + | |
- | {{ : | + | |
- | + | ||
- | This parameters page is also a good place to check that all batteries are connected and working properly. In normal working conditions, the current limit is 25A per cell. For example, 75A charge current limit ( 75 / 25 = 3 ) means there are 3 Pylontech battery modules connected. | + | |
