the Discharge Current Limit (DCL) to 0A, then the inverter will turn oﬀ in a software oﬀ state. The GX

device will remain on, as there is still DC voltage provided by the batteries for a while.

Note in this state an AC PV inverter will not produce any power, and will not start up, as it requires the

inverter to create the sine wave to synchronise.

If the AC grid or generator, or DC MPPT is connected, then the battery will begin to charge and then

the inverter will start itself again automatically, also resuming charge from an AC PV inverter.

If instead the battery becomes completely discharged the battery will further protect itself by not just

sending the 0A discharge limit, but also disconnecting DC voltage from the battery terminals (via

internal MOSFETS). As there is no DC voltage available on the terminals any more the GX device will

also shut down, and the inverter will also then be hard oﬀ (not just software oﬀ).

If you then reconnect a DC charge source, or AC input supply (grid or generator), after approximately

2 minutes the inverter will start up again, power the DC bus, powering up the GX device, and then

powering up the battery, and the system will recover.

Step 1. Check that the Pylontech battery is visible on the GX device list

If its not visible, check:

GX 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 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, by the Pylontech system via the CAN-bus cable. They are visible on the

Device List → Pylontech battery → Parameters menu.
