Are there foreign objects inside the unit: like screws, animals or insects?	Yes, no warranty. No.
Does the unit have burn marks on its internal parts, or does it smell burned?	Yes. No.
Does the unit have mechanical damage to any of its internal parts?	Yes, no warranty. No.
Does the unit have external mechanical, water or corrosion damage?	Yes, no warranty. No.
Does the unit have burn marks or melting marks on its housing, or does it smell burned?	Yes. No.
Does the unit have mechanical or burn damage to its electrical connectors?	Yes, no warranty. No.

3. First power up

Power the unit up and check
Remove all wires and cables from the unit. Connect the unit to a DC power supply or battery bank. Turn the DC supply on and turn the unit on via its main switch. Is there a DC short-circuit?	Yes, lodge a warranty claim. No.
Are there any LED(s) on or blinking?	Yes, go to 4. No.
For MultiPlus 500-1600VA or MultiPlus Compact only: Check the internal fuse and replace the fuse if it is broken. What is the outcome?	The fuse is not broken. The replacement fuse blew, lodge a warranty claim. Fuse replaced, no LED(s) are on or blinking. Fuse replaced, LED(s) are on or blinking, go to 4.
For all units except the MultiPlus Compact: Check if the remote link is in place; if not, place the link. Are any LED(s) on or blinking now? Note: To find the location of the remote link, refer to the product manual.	Yes, go to 4. No.
For the MultiPlus Compact: Check the DIP switches. DIP switch 1 should be set to "off", and DIP switch 2 should be set to "on". If this is not the case, set DIP switch 1 to "off" and set DIP switch 2 to "on". Are any LED(s) on or blinking now? Note: For more information on the DIP switches, see the product manual, chapter 5.5.	Yes, go to 4. No.

4. Bluetooth

Bluetooth check
Is the unit a "Smart" product, i.e., does it have built-in Bluetooth?	Yes. No, go to step 5.
Is Bluetooth active, i.e., do you see the unit listed in the device list of the VictronConnect app?	Yes, go to step 5. 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, consult the product manual. Is Bluetooth active now?	Yes, go to step 5. 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.

5. 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 If a firmware update is not possible using the VictronConnect app, try using VE.Flash instead.	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: For all models except RS models: Connect with VE.Configure. Go to the "Defaults" menu and click "Set all settings to default" Navigate to the "Assistant" tab and delete all assistants. For the RS models: 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 error codes? If so, try to resolve the errors by consulting the product manual. Did it get resolved?	No errors, go to 6. There were errors, but they were resolved. There were errors, but they were not resolved.
Write down the error number and name.	Error number: .... Error name: ....

6. Functionality

Inverter functionality check
Measure the DC voltage at the DC connection terminals inside the unit. Is this voltage the same as the battery voltage reading in the VictronConnect app?	Yes. No, lodge a warranty claim.
Measure the AC output using a True RMS multimeter. Are you measuring exactly 230Vac or 120Vac depending on the unit's AC voltage rating?	Yes. No, lodge a warranty claim.
Does the measured AC voltage correspond with the AC voltage reading in the VictronConnect app?	Yes. No, lodge a warranty claim.
Load the unit using incandescent light globes, electric heaters or any other type of resistive AC load. Can the unit power a load as high as its power rating without overload or temperature alarm?	Yes. No, lodge a warranty claim.
Is the unit making an unusual noise?	No. Yes, lodge a warranty claim.

Ground relay and back-feed relay safety circuit check - Only applicable to MultiPlus-II, EasySolar-II and Quattro-II
Scope: Bench test for unit reporting an Error 8 (ground relay) or Error 11 (back-feed relays).
Preparations, check the bench test supply: Measure the voltage between ground/earth and neutral. Ensure that it is below 30Vac. Usually the voltage between ground and neutral does not exceed a few volts. A voltage of around 230Vac indicates that line and neutral are swapped. Fix that before continuing. A voltage above 30Vac indicates problem in the grounding of either the test bench or the installation of the building. This needs to be fixed prior to continuing the test. Note that this bench test can only be conducted if the voltage between ground/earth and neutral is below 30Vac.
Benchtest: Switch the unit off. Connect a battery or power supply to the battery terminals. Connect AC input to the unit, including ground/earth. Make sure not to swap line and neutral. Double check line and neutral position by measuring the AC voltage between neutral and ground. This should not be above a few Volts maximum. Do not connect anything to the AC output terminals. Switch the unit on. Update the firmware to the latest version. If already on latest version, use VEConfigure to reset all settings to default (in the top menu select "Defaults" and then select "Set all settings to default"). Use VEConfigure and select the grid code “Other: not compliant to any grid code standard”. Do not use a gid code with “AC Neutral path externally joined”. Send all settings. Ensure that nothing is connected to the AC output terminals. CHECK: Does the unit start up and connect to the grid without errors? Background information: when wired with correct line, neutral and ground connections on the AC input, and nothing is connected to the output, if the unit works both in island mode (inverting) and connects to the grid (charging), then all relays and their testing circuits are OK. If the unit gives problems in the field, despite passing this bench test, then there is an issue in the electrical installation and the troubleshooting steps for Error 8 (ground relay) and Error 11 (back-feed relays) must be followed.	Yes, the unit is working as expected. No, lodge warranty claim.
