Victron Inverter-Charger Open-loop Configuration Procedure

Refer to the latest Discover Energy Systems documentation for battery values and the latest Victron documentation for details on menu navigation and the setup procedure.

  1. Set the Discover Lithium batteries to ON and set the inverter to ON.

  2. Connect your computer to the Victron GX device or inverter.

  3. On the computer, start the VE Configure 3 software configuration tool.

  4. Enable and disable parameter values according to the tables below.

  5. Send the parameters to the Victron inverter-charger and GX device.

  6. Toggle the On/Off/Charger Only switch to turn the inverter OFF and ON.

(1) The lowest operating voltage allowed. Increase voltage as required.

(2) Restart voltage after DC input low shutdown. Recommend setting to the minimum value (minimum varies according to the DC Input low shutdown value).

(3) 49.5 V / 24.75 V value (approximately 10% SOC) will trigger a low battery warning. Increase or decrease as preferred.

(4) ‘Enable AES’ has no relation to either the AES RACKMOUNT or HELIOS ESS battery. Refer to Victron manuals for information on the AES setting and function.
