If your Vue's whole-home numbers don't add up — Balance is unusually high or showing green, your monthly Total doesn't match your utility bill, or solar net metering isn't tracking right — this article covers all three because they share the same root causes. Most issues come down to one of: a sensor reversed, a phase mixed, a multiplier in the wrong place, or a calibration that needs to be re-run.
Quick Guide: What's the Symptom?
Balance is much higher than expected → jump to High Balance.
Balance is showing green (negative) → jump to Green / Negative Balance.
Total doesn't match my utility bill → jump to Doesn't Match Utility Provider.
Solar isn't showing as Net Production → jump to Solar / Net Metering Wrong.
What "Balance" Is
Balance is the difference between your whole-home Total (from the 200A main CTs) and the sum of your individual branch readings (from the 50A CTs):
Balance = Total Mains − Sum of Branch Circuits 1–16
In a normal home, Balance is positive and represents the energy used by circuits you don't have a 50A CT on (lighting, outlets, miscellaneous loads). When Balance looks weird, it usually means a sensor is reversed, missing, or counted twice.
High Balance
A higher-than-expected Balance most commonly comes from one of:
Missing 50A CTs. Open the Home screen circuit list and confirm every sensor you've installed is showing up. If one is missing, see Incorrect CT Sensor Readings.
Big circuits not yet sensored. If your dryer, EV charger, or HVAC don't have 50A CTs on them, their consumption rolls into Balance. Adding sensors to those circuits is the cleanest fix.
Mains over-counting. Confirm you have the right number of 200A CTs — one per live phase, no more. Compare your Total to your utility bill: if it's more than ±2% off, the mains are likely the issue.
Multipliers on lightly-loaded circuits. A 2.0× multiplier on a circuit with imbalanced legs can over- or under-state usage and skew Balance. Where possible, use two sensors and Circuit Merging instead (see Merging and Unmerging Circuits).
Don't try to allocate Balance manually. A high Balance is a signal that something needs troubleshooting — it's not a number to spread proportionally across your monitored circuits. Manually distributing the unmeasured energy will hide the real cause and make your data less accurate, not more.
Green / Negative Balance
A green Balance value means the sum of your branch circuits is greater than your Total Mains — mathematically impossible in a properly configured system. Common causes:
Solar generation that isn't flagged. If you have solar but no 50A CT on the solar circuit (or it's not configured as a Solar/Bi-Directional circuit), the device under-counts mains relative to branch totals.
200A mains under-counting. Missing a 200A CT on one phase, or a CT that's reversed or mis-calibrated, makes the mains read low.
50A CTs over-counting. Common causes: a sensor on a neutral line that shouldn't be, two sensors on the same wire counted as separate circuits, or a multiplier set higher than the actual ratio.
If green Balance persists after these checks, run the recalibration flow with the correct Solar/No-Solar selection — see Resetting Your Vue: Wi-Fi, Solar, and Recalibration.
Doesn't Match Utility Provider
Before troubleshooting, make sure you're comparing apples to apples:
Match the time period. The Emporia app uses calendar months (1st through last day). Your utility's billing cycle probably starts mid-month. Comparing Apr 1–30 against a Mar 15–Apr 14 utility bill will always look off. Set your billing date in the Emporia app to match your utility's cycle (Settings → Billing Date).
Compare full months, not days. Day-to-day variance is normal and doesn't reflect calibration. Compare a full month's kWh once your billing periods are aligned.
Confirm your accuracy expectation. The Vue is calibrated for ±2% on whole-home kWh against a utility meter. Larger gaps indicate an installation issue.
If you're more than 2% off after aligning billing periods:
Check 200A CT orientation. Each 200A CT's arrow must point toward the breaker, away from incoming power. A reversed mains CT can swing your Total dramatically.
Try reversing the A and B port connections. If you suspect the 200A CTs are mismatched to their phases, swap which CT is plugged into port A vs. port B and watch the Total Usage reading for an hour or so. If the gap shrinks, you've identified the issue and can leave the swap in place.
Check phase assignment on the harness. Black and Red must be on separate phases. Using a double breaker for both puts them on the same phase and undercounts the mains.
Look for upstream loads. If your panel is downstream of the utility meter and there's another panel or direct conduit upstream of the Vue's mains CTs, that load is invisible to the Vue. Check at the meter for additional connected panels.
Try a connection reset. Press the reset button on your Vue for 5 seconds and wait up to 5 minutes for data to reappear in the app. Frequent connectivity drops can leave gaps in cloud-side data — see Vue Offline Behavior for how the device handles outages.
Recalibrate. After any wiring change, run the recalibration flow.
Solar / Net Metering Wrong
If your home has solar and your Vue isn't tracking generation correctly, the issue is one of three things:
Issue 1 — Vue isn't flagged for solar. If the top of your circuit list shows Total Usage but never Net Production, the Vue was set up as no-solar. Run the recalibration flow and select I have Solar / Generation when prompted. See Resetting Your Vue: Wi-Fi, Solar, and Recalibration.
Issue 2 — 200A CTs in the wrong place. The 200A mains CTs must sit between the incoming grid power and the solar inverter's connection point — not downstream of the solar tie-in. If solar is connected to the mains directly (rather than through a breaker in the same panel as the Vue), the mains CTs may not see the bidirectional flow. If you're not sure, photograph your install and send it to Customer Support for a sanity check.
Issue 3 — Calibration needs to lock onto the correct phase voltages with solar present. Run the recalibration flow with these conditions:
Turn off solar generation during the reset (cover the panels, flip the solar disconnect, or run after dark). The Vue assumes any current it sees is grid-supplied during calibration.
Run as much consumption as you can during the reset (HVAC, water heater, dryer). At least 1 kW per phase helps the calibration lock in correctly.
Select I have Solar / Generation when prompted.
After a successful recalibration, generation appears as green/negative numbers and consumption appears as blue/positive numbers. Net Production at the top of the circuit list will swap to Net Usage when consumption exceeds generation.
If You're Still Stuck
Measurement-accuracy issues can be tricky — the symptom is rarely far from the cause but the cause itself can be subtle. Please contact our Customer Support team with:
Photos of your panel showing the CT placements and the wire harness routing.
Your Total Usage / Net Production reading for a recent full billing period.
Your utility's reported kWh for the same period.
Whether you have solar, battery, or other generation, and how it's connected to your panel.
For Persistent Issues, Consult an Electrician
If you've worked through the checks above and your numbers still aren't where they should be, a licensed electrician can verify your panel's actual wiring and confirm phase assignments. The Vue can only report on what it's measuring — if the panel itself is wired in an unusual way, on-site eyes are the fastest path to a fix.
