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.
Set the Discover Lithium batteries to ON and set the inverter to ON.
Connect your computer to the Victron GX device or inverter.
On the computer, start the VE Configure 3 software configuration tool.
Enable and disable parameter values according to the tables below.
Send the parameters to the Victron inverter-charger and GX device.
Toggle the On/Off/Charger Only switch to turn the inverter OFF and ON.
VE Configure 3 > General Tab
General Tab | AES RACKMOUNT | HELIOS ESS |
|---|---|---|
[AC1] Overruled by remote (1) | Enable | Enable |
[AC2] Overruled by remote (1) | Enable | Enable |
Dynamic current limiter | Enable | Enable |
External current sensor connected | Disable | Disable |
Enable battery monitor | Enable | Enable |
State of charge when Bulk finished (2) | 95% | 95% |
Battery capacity | Number of batteries x 100 Ah | Number of batteries x 314 Ah |
Charge efficiency (2) | 1.00 | 1.00 |
(1) Enable is recommended.
(2) Precautionary settings ignored during normal operation and communication with Discover lithium batteries.
VE Configure 3 > Inverter Tab
Inverter Tab | AES RACKMOUNT | HELIOS ESS |
|---|---|---|
DC input low shutdown (1) | 48.0 V | |
DC input low restart (2) | 52.0 V | |
DC input low pre-alarm (3) | 49.5 V | |
Enable AES (4) | Disable | |
(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.
VE Configure 3 > Charger Tab
Charger Tab | AES RACKMOUNT | HELIOS ESS |
|---|---|---|
Enable charger | Enable | Enable |
Battery Type (1) | Blank | Blank |
Lithium Batteries (1) | Enable | Enable |
Charge Curve (1) | Select: Fixed | Select: Fixed |
Absorption Voltage (1) | 55.2 V | 55.2 V |
Float Voltage (1) | 53.6 V | 53.6 V |
Charge Current | Number of batteries x 95 A | Number of batteries x 200 A |
Repeated absorption time (1)(2) | 1.0 < 3.0 Hr | 1.0 < 3.0 Hr |
Repeated absorption interval(1) | 7.0 Days | 7.0 Days |
Absorption time (1)(2) | 1.00 < 3.0 Hr | 1.00 < 3.0 Hr |
(1) Precautionary settings ignored during normal operation and communication with Discover lithium batteries.
(2) The recommended minimum is 1.0 hour. Multiple batteries may require a longer time to achieve a smooth completion of charge.
NOTE |
|---|
Confirm the Float Voltage after installation of any Victron ’Assistants’, and if necessary, set the Float Voltage back to 53.6 V. |
