-====== Victron & Pylontech =====+Moved out of draft and into live page here: 
 +https://​www.victronenergy.com/​live/​battery_compatibility:​pylontech_phantom
  
-The combination of Victron products with Pylontech lithium batteries has been tested and certified by the Victron and Pylontech R&D departments. ​ 
- 
-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:​start|Venus-device]] and can supports multiple battery modules connected in parallel. 
- 
- 
-===== 1. Product & system compatibility ===== 
- 
-^  Battery ^  US2000B ^  US2000B Plus ^  US3000 Plus ^ 
-|  Module capacity| ​ 2.4 kWh |  2.4 kWh |  3.5 kWh|  
- 
-=== 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:​start|]]) 
-  * Grid Backup 
-  * Off-grid 
- 
- 
-=== 1.2 A Venus-device is required, either Color Control GX (CCGX) or Venus GX (VGX) ===  
- 
-It is essential to use the CAN-bus connection of the [[venus-os:​start|Venus-device]] (eg CCGX or VGX) with the batteries for the keep-alive signal, communication of charge and discharge limits, error codes and state of charge. ​ 
- 
-The minimum required firmware version for the [[https://​www.victronenergy.com/​panel-systems-remote-monitoring/​color-control|Color Control GX]] is v2.15. It is highly recommended to use the latest firmware version on all connected devices, including CCGX/VGX, Inverter/​Charger and MPPTs. There are regular updates to improve performance and reliability. ​ 
- 
-In grid connected systems, advanced control functions are configurable in the ESS settings on the [[venus-os:​start|Venus-device]]. 
- 
-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. 
- 
-These inverter/​charger units must be connected to the [[venus-os:​start|Venus-device]] via the VE.Bus connection port.  
- 
- 
-=== 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:​start|Venus-device]]. Make sure the [[venus-os:​start|Venus-device]] runs v2.15 or later, and the MPPTs to 1.37 or the latest available version. ​ 
- 
-The MPPT requires connection to the [[venus-os:​start|Venus-device]] to regulate charge currents as the batteries require (due to temperature,​ etc) 
-To test operation, try disconnecting the [[venus-os:​start|Venus-device]] from the MPPT. After a time-out, the MPPT will stop charging and flash an error code on its LEDs. The error code is [[https://​www.victronenergy.com/​live/​mppt-error-codes#​err_67_-_no_bms|error #67: no BMS]]. ​ 
- 
-__MPPTs with a VE.Can port__ 
- 
-Use of VE.Can MPPT's with Pylontech batteries is not supported or documented. 
- 
- 
-===== 2. 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:​start|Venus-device]]. ​ 
- 
-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/​charger overload than the battery. ​ 
- 
-Some suggested battery sizings for common Victron inverter/​chargers are listed below. These are suggestions for reliable operation for single phase off grid and are not specified by Pylontech. ​ 
- 
-^ Inverter / Charger Model ^ Inv continuous watts @ 25 degrees ^ Inverter peak watts surge rating ^ Number of Pylontech modules ^ Battery continuous discharge watt rating ^ Battery peak discharge watt rating ^  
-| Multiplus 48/500/6 | 430 | 900 | 1 | 1200 | 4800 | 
-| Multiplus 48/800/9 | 700 | 1600 | 1 | 1200  | 4800 | 
-| Multiplus 48/1200/13 | 1000 | 2400 | 1 | 1200 | 4800 | 
-| Multiplus 48/3000/35 | 2400 | 6000 | 2 | 2400 | 9600 | 
-| Multiplus 48/5000/70 | 4000 | 10000 | 4 | 4800 | 19200 | 
-| Quattro 48/​8000/​110-100/​100 | 6500 | 16000 | 6 | 7200 | 28800 | 
-| Quattro 48/​10000/​140-100/​100 | 8000 | 20000 | 7 | 8400 | 33600 | 
-| Quattro 48/​15000/​200-100/​100 | 12000 | 25000 | 10 | 12000 | 48000 |

-===== 3. Wiring of CAN-bus cable between B-Box and Venus-device ===== 
- 
-You can connect multiple battery modules together to form a single large battery by connecting the RJ-45 cable supplied by Pylontech using the link ports on the battery. This is shown in more detail in the  [[https://​www.victronenergy.com/​live/​drafts:​pylontest#​example_wiring_diagram|example wiring diagram]] and Pylontech manual. 
- 
-The batteries will automatically detect and link to each other, no adjustment of dip switches or software changes are necessary on the batteries. ​ 
- 
-The battery with the empty link port 0 is the master battery. Using 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 of the master battery. Plug the side labeled Victron VE.Can into the [[venus-os:​start|Venus-device]]. 
- 
-Then, plug a [[https://​www.victronenergy.com/​accessories/​ve-can-rj45-terminator|VE.Can terminator]] in the other VE.Can socket on the [[venus-os:​start|Venus-device]]. Two VE.Can terminators are included with the package of the [[venus-os:​start|Venus-device]] as an accessory, only one is used. Keep the other one as a spare. 
- 
-More information about the cable can be found in [[battery_compatibility:​can-bus_bms-cable|its manual]]. 
- 
-Without properly connecting this cable, the battery will not show up on the display of the [[venus-os:​start|Venus-device]]. The battery will also turn itself off. 
- 
-It is important to ensure this connection and display of the battery on the [[venus-os:​start|Venus-device]] display before attempting firmware updates or settings changes on other devices if they depend on the power supply from the battery. Without this connection, the battery may turn off unexpectedly. ​ 
- 
- 
-===== 4. VEConfigure settings ===== 
- 
-This section presumes familiarity with [[https://​www.victronenergy.com/​upload/​documents/​Manual-A-Guide-to-VEConfigure-EN.pdf|VEConfigure software.]] ​ 
- 
-=== 4.1 General tab === 
-  * Check the "​Enable battery monitor"​ function 
-  * Set the battery capacity to the total capacity of the battery: eg 50Ah times the number of battery modules for the 2000B Plus model. 
-  * The other parameters ("​State of charge when bulk finished"​ and "​Charge efficiency"​) can be left to their default setting: They are ignored for a Pylontech installation. 
- 
-=== 4.2 Charge parameters === 
- 
-=== Charger tab === 
-^ Parameter ​             ^ Setting ^ 
-| Battery type           | Lithium | 
-| Charge curve           | Fixed   ​| ​ 
-| Absorption voltage ​    | 53.2 V  | 
-| Float voltage ​         | 53.0 V  |  
-| Absorption time        | 1 Hr    | 
- 
-Note: make sure to double check the float voltage after completing Assistants, and if necessary set it back to 53.0 V. 
- 
- 
-=== Option A: ESS Assistant === 
-If you are using the battery as part of a grid connected ESS system - run the ESS Assistant in VEConfigure. 
- 
-Select the externally managed Lithium battery option 
- 
-{{ :​battery_compatibility:​ess-battery-system-selection.png?​nolink |}} 
- 
-^ ESS Parameter ^ Settings ^ 
-|Sustain voltage. ​      | 48V| 
-|Dynamic cut-off values | set all values to 46V.| 
-|Restart offset: ​       |4V| 
- 
- 
-=== Option B: Off-grid system using CAN-bus cable. ==== 
- 
-You will need the latest firmware on all connected devices. ​ 
- 
-On the [[venus-os:​start|Venus-device]],​ go to Settings, System setup: 
- 
-^Venus Settings -> System Setup Parameter ^ Value ^  
-|DVCC|ON| 
-|Shared Voltage Sense |OFF|  
- 
- 
-In the Inverter tab of VEConfigure 
-^VEConfigure Inverter Parameter ​             ^Setting^ 
-|DC input low shut-down | 47V| 
-|DC input low restart ​  | 51V| 
-|DC input low pre-alarm* | 51V| 
- 
- 
-* The pre-alarm setting is dependant on your preference and on site specific requirements. You may wish for this to be activated earlier in an off grid situation to allow time to start a backup generator. If the system is configured in ESS mode, you may not wish to have this alarm trigger until below the Sustain threshold voltage, as this system is in no danger normally and will '​sustain'​ without needing to trigger an alarm. ​ 
- 
- 
-=== 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:​start|Venus-device]] to the inverter/​charger and MPPT.  
- 
-  * 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: 
-{{ :​battery_compatibility:​pylon-menu.png?​nolink&​400 |}} 
- (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 
-{{ :​battery_compatibility:​pylon-params.png?​nolink&​400 |}} 
- 
-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. ​ 
- 
-===== 6. Configure VE-Direct MPPT ===== 
- 
-In normal operation the MPPT charge characteristics are governed by the [[venus-os:​start|Venus-device]] connected to the Pylontech battery. ​ 
- 
-This section presumes familiarity with [[victronconnect:​start|VictronConnect]] 
- 
-The settings below are a precautionary measure. ​ 
- 
-^MPPT Parameter ^ Setting ^ 
-|Battery voltage. ​    |48V| 
-|Absorption voltage ​  |53V| 
- 
-===== 7. Example Wiring Diagram ===== 
- 
-{{ :​battery_compatibility:​pylon-diagram-2018-12-28.jpg?​direct&​800 |}} 
- 
-===== 8. Troubleshooting ===== 
- 
-If the system is not operating correctly, go through these steps. 
- 
-=== Step 0. If the Inverter/​Charger or Venus-device does not switch on === 
- 
-As a safety precaution, the inverter/​charger will not switch on if the [[venus-os:​start|Venus-device]] is not on. If you are unable to start the system due to a total system blackout / battery shutdown due to low voltage, you may need to disconnect the VE.BUS connection cable between the inverter/​charger and [[venus-os:​start|Venus-device]]. ​ 
- 
-You can then start the inverter/​charger from an external charge source such as a generator or grid connection. Once the inverter/​charger has started, it should supply power to the DC terminals and this should start the [[venus-os:​start|Venus-device]] and Pylontech battery again. You will need to then reconnect the VE.Bus Communications cable back to the inverter/​charger and [[venus-os:​start|Venus-device]]. 
- 
-=== Step 1. Check that the Pylontech battery is visible on the Venus-device list === 
- 
-{{ :​battery_compatibility:​pylon-menu.png?​nolink&​400 |}} 
- 
-If its not visible, check: 
- 
-  * [[venus-os:​start|Venus-device]] firmware version (update to latest version, v2.15 or later) 
-  * CAN-bus communication cabling between Pylontech and Victron system. Make sure that it is in the right way around. 
-  * Pylontech system is up and running (leds are) 
- 
-=== Step 2. Check that the Pylontech battery is ready for use === 
- 
-Check the Max Charge Voltage parameter. This voltage parameter is sent, together with the other three parameters, ​ by the Pylontech system via the CAN-bus cable. They are visible on the [[venus-os:​start|Venus-device]]:​ Device List -> Pylontech battery -> Parameters menu. 
- 
-===== 9. FAQ ===== 
- 
-**The maximum charge and discharge current is limited to 25A, but the data sheet tells me the maximum is 100A.** ​ 
- 
-The maximum current is limited to keep the battery healthy and reach the 10 year guarantee. In off-grid, the inverter can draw more than the 25A limit to run the loads, make sure you have sufficient batteries installed to keep the load per battery around this limit. 
- 
-**After charging the battery the charge current often changes between 0A and 25A.** ​ 
-This is caused by cell balancing inside the battery. This happens with new batteries and after a deep discharge.
