4. SignOff Quick Test - bèta-version

Run the Signoff Quick Test

The Signoff Quick Test is a short automated battery charge/discharge cycle used to validate that an inverter installation is functioning correctly before sign-off. It takes approximately 80 seconds to complete, and produces a clear PASSED or FAILED result with supporting diagnostic data. Use this test as the final verification step before handing over a newly commissioned system.

Prerequisites

• LIFEPOWR FlexiObox installed, online, and reachable

• Inverter successfully paired and communicating (FlexiObox receiving inverter data)

• Grid meter data available (grid power readable by the FlexiObox)

• Logged in user account to the partner portal when navigating to the device info page

How the Test Works

The Signoff Quick Test sends a fixed sequence of battery setpoints directly to the inverter, bypassing the normal EMS output for the duration of the test. The EMS continues to run, but its setpoints are silently discarded — the FlexiObox only forwards test profile commands to the inverter.

The test profile runs four steps in sequence:

ℹ️ Note: The actual setpoint value used during execution is scaled to your inverter's rated capacity. The values above reflect the default profile; your system may apply different absolute wattages based on configuration.

⚠️ Warning: While the test is running, the EMS has no control over the inverter. Grid export/import will follow the test setpoints, not the energy management strategy. Inform the customer before running the test on a live site.

Step-by-Step Instructions

Trigger the Test

1. Navigate to the device info page of the FlexiObox you want to test. This is possible via scanning the QR on the FlexiObox or via the partner portal.

2. On the installation overview page you will see a Signoff Quick Test section with a problem indicator if no passed test has been recorded yet

3. Click the Start Test button to initiate the Signoff Quick Test

4. The test will start and you are able to monitor the progress via the device info page.

Monitor Progress

1. The app automatically polls the device for test status every few seconds. Watch the Test Status indicator update through the following states:

   • WAITING — test trigger received, pre-flight checks in progress

   • RUNNING — active test execution; current setpoint and elapsed % are shown

   • PROCESSING — test steps complete; results are being calculated

   • PASSED or FAILED — final result available

ℹ️ Note: You do not necessarily need to keep the app screen open during the test. The test runs on the device and the final result is stored. You can navigate away and return to check the outcome.

Stop the Test Early (if needed)

1. To cancel the test at any point, tap Stop Test in the app. The test will exit cleanly and the status will update to CANCELLED. You can restart immediately after a user-initiated cancellation.

Pass/Fail Criteria

The Signoff Quick Test evaluates up to four requirements. Which requirements are actually checked depends on the battery's State of Charge (SoC) at the time of the test:

• SoC between minimum and 90% — both the charge and discharge requirements are active. All four requirements must pass.

• SoC at or below the configured minimum (battery empty) — the discharge requirement (BATTERY_DISCHARGES_IF_NOT_EMPTY) is automatically skipped; the system cannot expect the battery to discharge. The remaining three requirements must pass.

• SoC at or above 90% (battery full) — the charge requirement (BATTERY_CHARGES_IF_NOT_FULL) is automatically skipped. The remaining three requirements must pass.

In practice, the test always evaluates at least one charge or discharge requirement, and both when the SoC falls between the configured limits.

Expected Result

A successful test ends with a PASSED status visible in the app, along with a timestamp confirming when the test completed. If the status shows FAILED or CANCELLED, review the error message displayed in the app and refer to the troubleshooting section below.
