MPPTs. There are regular updates to improve performance and reliability.
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, and a necessary first step when troubleshooting issues.
These inverter/charger units must be connected to the GX 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 GX device. Make sure the GX device runs v2.15 or later, and the MPPTs
to 1.37 or the latest available version.
The MPPT requires connection to the GX device to regulate charge currents as the batteries require
(due to temperature, etc) To test operation, try disconnecting the GX 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 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 GX 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 battery modules to supply the inverters startup inrush surge
currents that charge the capacitors when the inverter is first connected, this occurs prior to any loads
being connected. There is also the subsequent potential current demands of the loads connected to
the inverter. It is much more desirable to have the inverter/charger overload than the battery, as the
inverter will automatically recover, whereas the battery may require intervention once in a fault state.
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.
