3. Latching relay check

Latching relay check
Is the unit equipped with red safety latching relays near the PV connections as indicated in the below image?	Yes. No, go to section 4
Indicate the position of the relays from left to right. Caution DO NOT manually operate or reset the levers. If the lever is in a closed position, this indicates a safety trip because of a (warrantable) fault.	Open / close Open / close Open / close Open / close
Are any of the levers in the closed position (lever is up)?	Yes, lodge a warranty claim. No.

4. First power up

Power up check

In case the unit did not turn on, check and rectify (if needed) the following: Has the unit been switched on? Is the remote terminal link in place? Is the on/off switch wire terminal correctly connected to the PCB? Does the unit turn on now?	Yes. No, lodge a warranty claim.
Does the display indicate an error? If so, write it down: .................................................................................................................. .................................................................................................................. .................................................................................................................. ..................................................................................................................	Yes. No.

5. Bluetooth

Bluetooth check
Is Bluetooth active, i.e., do you see the unit listed in the device list of the VictronConnect app?	Yes, go to section 6. No.
If Bluetooth is not active, it is unlikely to be a faulty Bluetooth module. More likely, Bluetooth has been turned off in the VictronConnect settings. To re-activate Bluetooth: Connect to the unit's VE.Direct port using a VE.Direct to USB interface and a computer, Android phone or Android tablet. Open the VictronConnect app and navigate to the unit's "Settings" page. From the "Settings" page, go to the "Product Info" page. Verify if Bluetooth is enabled. If it is not enabled, activate it. Is Bluetooth active now?	Yes, go to section 6. No.
If Bluetooth is still not active, rule out the following: Are there problems with your phone or tablet? Are you within Bluetooth range? Just one phone or tablet can connect via Bluetooth at once. If another is connected, the unit will be listed but greyed out in VictronConnect app. Consult the product manual and the VictronConnect manual to try to resolve the Bluetooth issue. Is Bluetooth active now?	Yes. No, lodge a warranty claim.

Bluetooth check

Is Bluetooth active, i.e., do you see the unit listed in the device list of the VictronConnect app?

Yes, go to section 6.
No.

If Bluetooth is not active, it is unlikely to be a faulty Bluetooth module. More likely, Bluetooth has been turned off in the VictronConnect settings.

To re-activate Bluetooth:

Connect to the unit's VE.Direct port using a VE.Direct to USB interface and a computer, Android phone or Android tablet.
Open the VictronConnect app and navigate to the unit's "Settings" page.
From the "Settings" page, go to the "Product Info" page.
Verify if Bluetooth is enabled. If it is not enabled, activate it.

Is Bluetooth active now?

Yes, go to section 6.
No.

If Bluetooth is still not active, rule out the following:

Are there problems with your phone or tablet?
Are you within Bluetooth range?
Just one phone or tablet can connect via Bluetooth at once. If another is connected, the unit will be listed but greyed out in VictronConnect app.
Consult the product manual and the VictronConnect manual to try to resolve the Bluetooth issue.

Is Bluetooth active now?

Yes.
No, lodge a warranty claim.

6. Firmware and settings

Update the firmware and reset the settings to default
Connect via an interface (or Bluetooth) to the VictronConnect app and navigate to the unit. Is this possible?	Yes. No, not possible; lodge a warranty claim.
Check if the firmware is up to date. If the firmware is not up to date, update the firmware to the most recent version using the VictronConnect app: Go to the VictronConnect settings page. On the settings page, click on the "3 dots" symbol in the top right-hand corner. Select "Product info". On the product info page, check and/or update the firmware. Notice Note that when connected via Bluetooth, both the solar charger and the BLE module needs to be up to date. If connecting via VE.Direct, only the solar charger needs to be up to date.	Yes, the firmware has been updated. Yes, the firmware was already up to date. No, not possible to update the firmware.
Save the unit's settings. File the settings under its serial number and keep the file on record for future reference. To save the settings: Go to the VictronConnect settings page. On the settings page, click on the "disk" symbol at the top.	Yes, the settings file has been saved. No, not possible to save the settings.
Reset all settings to default: Go to the VictronConnect settings page. On the settings page, click on the "3 dots" symbol in the top right-hand corner of the page and select "Reset to defaults".	Yes, the settings are set to default. No, not possible to set the settings to default.
Does the VictronConnect app display any active error codes? If so, try to resolve the errors by consulting the product manual. Did it get resolved?	No errors. There were errors, but they were resolved. There were errors, but they were not resolved.
If there is an active error, write down the error number(s) and name(s). Use this form's "Remarks" section if more space is needed.	Error number: .... Error name: ....
Check the history. Were there any historical errors? If so, write them down. Save a copy of the history file for your reference.	Yes, Number(s): .... No.
Check the history tab. What was the highest PV voltage recorded? Compare this to the rated maximum PV voltage of the solar charger. Has the PV voltage been higher than 450V?	Yes, no warranty. No.
Check the trents tab. Does it contain data?	Yes, make a screenshot and submit it with the RMA. No.

7. Functionality

Solar charger functionality check
Prepare the solar charger for the functionality test: Connect the battery terminals to a 48V battery. Connect the PV terminals to a power supply capable of supplying at least 120VDC. Notice Skip this section step if you cannot provide a 120VDC to the PV terminals.	Done. If unable to provide 120VDC, go to section 8.
Measure the voltage on the solar charger PV terminals. Compare this to the solar voltage as indicated in the VictronConnect app. Are they both the same? A small deviation is allowed due to measurement inaccuracies.	Yes. No, lodge a warranty claim.
Measure the voltage on the solar charger battery terminals. Compare this to the battery voltage as indicated in the VictronConnect app. Are they both the same? A small deviation is allowed due to measurement inaccuracies.	Yes. No, lodge a warranty claim.
Is the battery being charged? Check if the solar charger is progressing through the bulk, absorption and float charge stages. Is this the case? Background information: Charging begins when the PV voltage reaches at least 120V and continues as long as it stays above 65V.	Yes. No, lodge a warranty claim.
Force the solar charger to provide more charge current by connecting it to an empty battery or by switching on a large DC load connected to the same battery. Is the unit able to provide its full current rating?	Yes. No, lodge a warranty claim.
Measure the charge current with a DC current clamp. Is the charge current the same as indicated in the VictronConnect app? A small deviation is allowed due to measurement inaccuracies.	Yes. No, lodge a warranty claim.
While the solar charger is providing the full current, measure the battery voltage. Compare this to the voltage as indicated in the VictronConnect app. Do the voltages deviate less than 3% from each other?	Yes. No. This is probably not warrantable as bad cables, or cable connectors can cause it.
