Symptoms
Battery begins importing electricity even while solar generation exceeds house consumption. This guide addresses that particular contrast, not every fault that can occur with the product or service.
- Observable failure: Battery begins importing electricity even while solar generation exceeds house consumption.
- Control test: Compare battery charging mode, scheduled import windows and solar production across one stable interval.
- A confirmed correction must meet this outcome: Battery follows the intended documented solar-first or tariff mode under a stable test.
Write down the exact sequence that reproduces the failure and the moment it stops. Intermittent failures are easiest to isolate when the same short test is repeated before and after one change.
Why It Happens
Energy dashboards display interpreted measurements. Sign conventions, sensor mapping, billing intervals and actual electrical behavior can differ; compare independent evidence before concluding that a physical circuit is faulty.
The important distinction is whether time-of-use tariff schedule prioritizes grid or battery reserve target changes charging policy explains the observed difference. Meter or app import sign is reversed remains another plausible explanation until the comparison rules it out.
Three competing explanations
- Time-of-use tariff schedule prioritizes grid.
- Battery reserve target changes charging policy.
- Meter or app import sign is reversed.
These are hypotheses. Do not infer a hardware defect, account restriction or network outage from one status indicator alone. A result that supports time-of-use tariff schedule prioritizes grid does not automatically exclude battery reserve target changes charging policy; the comparison needs to separate them.
Before Making Changes
Do not open panels, meters or high-voltage enclosures. Electrical measurements beyond the user interface require a qualified professional. Do not bypass grid charging protection or alter electrical connections.
Preserve the current state: note the affected product or account, current mode and time of the failed attempt. If settings will be changed, photograph or write down their original values. Keep copies of any unique files or evidence before overwriting anything.
Use a non-sensitive sample whenever possible. If the issue involves a shared device, building system, workplace account or regulated equipment, obtain the appropriate owner or administrator permission first. Stop if the test would compromise security, electrical protection, access or an animal's welfare.
Problem-Specific Diagnosis
Run this discriminating test before restarting or resetting the entire system: Compare battery charging mode, scheduled import windows and solar production across one stable interval. Compare the observed result against the three paths below.
| Observation or suspected layer | Interpretation | Next controlled check |
|---|---|---|
| Time-of-use tariff schedule prioritizes grid | If the failing state changes under the comparison, time-of-use tariff schedule prioritizes grid is plausible. This is not yet proof. | Repeat with that one factor changed, then return to baseline. |
| Battery reserve target changes charging policy | If the first change has no effect but a supported configuration differs, battery reserve target changes charging policy moves higher on the list. | Inspect the relevant option or documented behavior without clearing unrelated settings. |
| Meter or app import sign is reversed | If both earlier paths are contradicted, investigate whether meter or app import sign is reversed accounts for the timing or device-specific result. | Collect an event timestamp or status report for qualified support. |
Now apply the least-disruptive change that corresponds to the evidence: Inspect user-configurable charge schedule and tariff mode without changing wiring. Avoid treating all three hypotheses at once; simultaneous changes erase the diagnostic value of the test.
Step-by-Step Troubleshooting
Begin with reversible comparisons. Use Advanced only if the evidence points to a deeper problem.
Verify the affected workflow
Battery begins importing electricity even while solar generation exceeds house consumption. Write down where it happens, its most recent time and the state displayed by the product. Do not treat a nearby working feature as proof the whole path is healthy.
Run the safe comparison
Compare battery charging mode, scheduled import windows and solar production across one stable interval. Use the same device, account and operating conditions where practical. Note what remains unchanged so the comparison is meaningful.
Try the smallest safe intervention
Inspect user-configurable charge schedule and tariff mode without changing wiring. Make one adjustment at a time and preserve the previous value so it can be restored if the result becomes worse.
Confirm the real outcome
Battery follows the intended documented solar-first or tariff mode under a stable test. Repeat the complete user-facing operation and then make sure unrelated protections and functions still work. If the result is inconsistent, restore the previous setting and continue diagnosis.
Separate the three suspected layers
Assess evidence for time-of-use tariff schedule prioritizes grid, battery reserve target changes charging policy and meter or app import sign is reversed separately. A positive result for one path is not evidence for every path. Preserve before-and-after observations, including timestamps.
Check the responsible subsystem
Compare inverter energy-flow logs with the actual bidirectional utility meter and installer settings. Gather only logs and supported diagnostic views that apply to this exact scenario; do not change service-wide policy or hardware wiring.
Validate the unaffected path
Revisit the comparison: Compare battery charging mode, scheduled import windows and solar production across one stable interval. If the first suspected cause is not supported, compare the behavior predicted by battery reserve target changes charging policy with the behavior predicted by meter or app import sign is reversed. Keep the first correction reversible.
Commit or escalate with evidence
Confirm: Battery follows the intended documented solar-first or tariff mode under a stable test. If that cannot be reproduced, restore the original safe configuration and send sanitized observations to the equipment manufacturer, utility or a licensed electrician. Safety boundary: Do not bypass grid charging protection or alter electrical connections.
Solution Checklist
Solution Checklist
Common Mistakes to Avoid
- Assuming time-of-use tariff schedule prioritizes grid is proven simply because the visible symptom matches this page.
- Changing multiple accounts, rules, connections or device settings before running the control: Compare battery charging mode, scheduled import windows and solar production across one stable interval.
- Skipping this safety boundary: Do not bypass grid charging protection or alter electrical connections.
- Resetting, formatting, deleting credentials or replacing hardware without a confirmed backup, a supported recovery path and evidence that the step is necessary.
A setting that makes one symptom disappear is not always the correct permanent configuration. If it disables another essential function, revert it and investigate the underlying dependency rather than leaving an unsafe workaround in place.
How to Verify the Fix
The primary pass condition is specific: Battery follows the intended documented solar-first or tariff mode under a stable test. Repeat the original workflow, not a loosely related shortcut, and confirm both the previously failing behavior and an unaffected comparison still work.
- Record the before-and-after state in the same location, account and operating mode.
- Repeat the original comparison: Compare battery charging mode, scheduled import windows and solar production across one stable interval.
- Check the stated pass result: Battery follows the intended documented solar-first or tariff mode under a stable test.
- Confirm that normal security, notification, storage or physical safety protections remain enabled.
If the result works only once or disappears after reopening the app, reconnecting the accessory or waiting for the next scheduled event, treat the issue as intermittent instead of fixed. Keep the event time and what changed between attempts.
If the Problem Continues
If the safe correction does not work, move to a focused deeper investigation: Compare inverter energy-flow logs with the actual bidirectional utility meter and installer settings. This is a different path from the first settings check; use it only if the device or service supports the required diagnostics.
When escalating to the equipment manufacturer, utility or a licensed electrician, provide the exact symptom, result of the control test, changes already tried, time of occurrence and any non-sensitive error or status data. Explain whether time-of-use tariff schedule prioritizes grid, battery reserve target changes charging policy and meter or app import sign is reversed were supported or contradicted by evidence.
Do not share account recovery codes, private documents, live access tokens, sensitive location histories or full recordings merely to prove the problem. Redact or summarize identifiers before opening a public support request.
Prevent Recurrence
Keep a short reference note with the working configuration and the successful check: Battery follows the intended documented solar-first or tariff mode under a stable test. After an app update, firmware change, network migration or scheduled clock change, run the same short test before depending on the function again.
Watch for the condition that originally made the failure visible: Battery begins importing electricity even while solar generation exceeds house consumption. Where practical, retain an alternative approved way to perform the essential task so that one device, cloud service or interface does not become a single point of failure.
FAQ
How can I tell whether time-of-use tariff schedule prioritizes grid is responsible?
Run the controlled comparison: Compare battery charging mode, scheduled import windows and solar production across one stable interval. A change that specifically affects the failing layer supports this hypothesis, but repeat it before changing permanent settings.
What if the real cause is battery reserve target changes charging policy rather than time-of-use tariff schedule prioritizes grid?
Do not repeat the initial correction blindly. Check the supported diagnostic path: Compare inverter energy-flow logs with the actual bidirectional utility meter and installer settings. Keep the earlier working configuration recorded so you can reverse the test.
When is this particular issue resolved?
The decisive result is: Battery follows the intended documented solar-first or tariff mode under a stable test. If it fails after the normal workflow is repeated, document whether meter or app import sign is reversed still explains the remaining behavior and escalate with non-sensitive observations.
