New Model (2019 and later) VE.Can MPPTs are also supported from firmware version 1.06 and above.
Be aware that some GX devices (e.g. CCGX) only have a single CANBus interface, and that is required
for the battery communications. So if you use a new VE.Can MPPT, it must also be with a GX device
that has more than one CANbus interface, e.g. the Cerbo GX.
Old model VE.Can MPPTs (pre 2019) are not supported.
2. Minimum Battery Sizing Recommendations
Once DVCC is enabled on the GX device, the charge and discharge rates are managed by the
Pylontech battery.
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.
Using the above formula, an example of minimum system sizing based on the US2000 battery module
is below. Each battery module is approximately 50Ah at 48V, can provide 25A continuous charge and
discharge and 100A peak for 1 minute.
