Multi/Quattro and ESS Assistant configuration — Ensure correct settings in VEConfigure

What does Multi/Quattro and ESS Assistant configuration mean?

Proper configuration of the Multi/Quattro and ESS Assistant in VEConfigure is crucial for system operation. Incorrect settings can lead to unexpected behavior, such as the system not supplying battery energy to AC loads when the grid is connected.

• Incorrect country code selected in the Grid tab.
• ESS Assistant not added or incorrectly configured.
• Built-in battery monitor disabled.
• Incorrect battery type or charge parameters set.
• ESS Assistant disabling PowerAssist and Dynamic current limiter.
• DIP switches incorrectly set on VE.Bus BMS systems.

Click steps to track your progress.

1. 1

   Ensure the correct country code is selected in the Grid tab of VEConfigure (a password may be required).

2. 2

   Add the ESS Assistant via the Assistants menu in VEConfigure.

3. 3

   Verify that the 'built-in battery monitor' is enabled in the General tab.

4. 4

   Confirm the correct battery type and charge parameters (voltages, current) are set in the Charger tab; these override MPPT settings in an ESS setup.

6. 6

   For VE.Bus BMS with Multi Compact, check DIP switches: DIP 1 ON, DIP 2 OFF.
