- | {{ :battery_compatibility: | + | It is essential to use the CAN-bus connection of the [[venus-os:start|GX 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. |

+ | |||
+ | === 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. | ||
+ | |||
+ | |||
+ | ===== 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: | ||
+ | |||
+ | 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/ | ||

+ | ===== 3. CAN-bus Wiring ===== | ||
+ | |||
+ | {{: | ||
+ | |||
+ | 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:// | ||
+ | |||
+ | 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. | ||
+ | You must use the //VE.Can to CAN-bus BMS type B Cable//, part number ASS030720018, | ||
+ | |||
+ | Plug the type B cable with 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: | ||
+ | |||
+ | 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: | ||

- | | + | * 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. |

+ | Due to the reliability of the grid supply and the behaviour of the sustain voltage threshold in ESS; you may wish to suppress the low voltage pre-alarm warning so that it does not trigger every day on its regular deep cycle. See [[https:// | ||
+ | |||
+ | |||
+ | === 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. | ||
+ | * Discharge Current Limit set to 0A at 47V, inverter will turn off. | ||
+ | * Over-charge and Over-discharge Current Limit 102A for 15 seconds, 200A for 0.1 seconds and 400A short circuit current. | ||
+ | |||
+ | If operation is attempted outside the operating range, the battery will disconnect to protect itself. | ||

+ | {{ : | ||
+ | |||
+ | If its not visible, check: | ||
+ | |||
+ | * [[venus-os: | ||
+ | * 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 on) | ||
+ | |||
+ | === 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, | ||
+ | |||
+ | === Step 3. Check the Pylontech manual === | ||
+ | |||
+ | The Pylontech manual contains additional diagnostic and troubleshooting information, | ||
+ | |||
+ | ===== 9. FAQ and Known Issues===== | ||
+ | |||
+ | ==== 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. | ||
+ | |||
+ | ==== My system isn't charging at the rated capacity, or my PV is shutting down ==== | ||
+ | |||
+ | Pylontech' | ||
+ | |||
+ | You can confirm if this is affecting your installation be entering the Pylontech Battery menu on your GX device, and then the Parameters Menu. This will report the Charge Current Limit (CCL) and Discharge Current Limit (DCL). | ||
+ | |||
+ | ==== My system only charges the battery to 52V ==== | ||
+ | When DVCC is enabled, the battery (via the CAN-bms) is responsible for the charge voltage. The Pylontech battery requests a charge voltage of 53.2V. We have however found that in practice this is too high. | ||
+ | |||
+ | The Pylontech battery has 15 cells in series, so 53.2V equates to 3.55V per cell. This is very highly charged and makes the system prone to go overvoltage. | ||
+ | |||
+ | It should also be noted that a LiFePO4 cell stores very little additional energy above 3.45V. | ||
+ | |||
+ | For this reason we opted to override the BMS and cap the voltage at 52V. This sacrifices almost none of the capacity and greatly improves the stability of the system. | ||
+ | |||
+ | ==== The battery won't charge to 100% ==== | ||
+ | Also see the question above. The state of charge of the battery is estimated based on the overall voltage and on how well balanced the internal cells are. Because we cap the battery voltage at 52V, the state of charge will sometimes rise very slowly once it reaches the mid-90s. This is normal and usually resolves over time. | ||
