Follow-up — Bluetti Elite 30 V2 with High Standby Power Consumption (Final Results)

Product Discussion BLUETTI Elite & EB Series
1

Hello everyone,


This post is a follow-up to my original thread, “Bluetti Elite 30 V2 with High Standby Power Consumption.” Since I can no longer edit that post to add the final test results or correct a few minor mistakes, I created this new one to provide the complete and updated findings.


After conducting additional tests and refining the methodology, I’m now sharing the final results for my Bluetti Elite 30 V2 — with a focus on real-world power consumption, efficiency, and detailed measurement procedures.


Below you’ll find all final data collected from my Bluetti Elite 30 V2.

Note

The table above compares measured vs. rated output power to validate the accuracy of the unit’s internal sensors.

:test_tube: Testing

Note

  • The ± symbol indicates the measurement tolerance of the equipment used.
  • Grid/Solar Plug-in and Grid/Solar Not-Plug-in results show negligible variance (<0.5%).
  • Separate tests were conducted for Base Standby + Bluetooth and Base Standby + Wi-Fi, with results falling within a ± 1 W margin. As a result, these modes are grouped together in the standby results table.
  • Total Load represents the combined output power from both DC Output and AC Inverter sources.
  • Average Power is the estimated average hourly power consumption, calculated from the change in State of Charge over time (Δ SoC).
  • Conversion Losses represent the difference between total energy used (Energy used) and the calculated standby-adjusted output energy (Output Total).
  • The Depth of Discharge (DoD) and inverter efficiency (η) values can be found in the Bluetti Elite 30 V2 manual under FAQs – Q5: “How to calculate the operation time?”

Calculation methods (Important)

  • Energy used (Wh):
    Energy used = Battery capacity (Wh) × Δ SoC (as decimal)


    Example: If Δ SoC = 47%, then the decimal value is 0.47.


  • Average Power (W):
    Average Power = Energy used (Wh) / Duration (h)


  • Output Total (Wh):
    Output Total = (Total Load (W) + Standby Power for Mode (W)) × Duration (h)


  • Conversion Losses (Wh):
    Conversion Loss = Energy used (Wh) - Output Total (Wh)


  • Conversion Losses Percentage (%):
    Conversion Loss (%) = (Conversion Loss (Wh) / Energy used (Wh)) × 100


  • Operation Time (h):
    Operation Time = (Battery Capacity × DoD × η) / (Load + Self-consumption)


  • Example — Operation Time:

    • Battery capacity: 288 Wh
    • Load: 40.96 W
    • Self-consumption: 9.84 W
    • Depth of Discharge (DoD): 0.95
    • Inverter efficiency (η): 0.90

    Operation Time = (288 × 0.95 × 0.90) / (40.96 + 9.84) = 246.24 Wh / 50.80 W ≈ 4.85 hours


  • Example — Discharge Test:

    • Battery capacity: 288 Wh
    • Energy delivered (Measured): 200 Wh
    • Duration: 4 h 53 m ≈ 4.883 h

    Average Power = 200 Wh / 4.883 h ≈ 40.96 W


  • Charge Efficiency (%):
    Charge efficiency = Battery capacity (Wh) / Consumed Energy (Wh)


  • Discharge Efficiency (%):
    Discharge efficiency = Delivered Energy (Wh) / Battery capacity (Wh)


  • Total Round-trip Efficiency (%):
    Round-trip efficiency = Delivered Energy (Wh) / Consumed Energy (Wh)


  • Total System Loss (%):
    Total system loss = 100% - Round-trip efficiency (%)

Efficiency Test Results

Test Results Overview

Parameter Discharge Test (100% → 0%) Charge Test (0% → 100%)
Start Time 11:05 16:00
End Time 15:58 17:30
Total Duration 4h 53m 1h 30m
Power / Mode Constant Load (~41 W) Turbo Mode (~380 W)
Total Measured Energy 200 Wh (Delivered) 354 Wh (Consumed)

Note

The unit delivered 200 Wh during the full-discharge test, lower than the rated 288 Wh battery capacity, primarily due to inverter and conversion losses.

Efficiency Summary

AC Input (grid power) Value DC Input (solar power) Value
Charge Efficiency 81.36% Charge Efficiency N/A
Discharge Efficiency 69.44% Discharge Efficiency N/A
Total Round-trip Efficiency 56.50% Total Round-trip Efficiency N/A
Total System Losses 43.50% Total System Losses N/A

Note

The metrics under the DC Input column are marked as Not Applicable (N/A) because the required instrumentation for DC charging efficiency measurements was not available for this test.
