These figures summarize readings reported in the source video and apply to the tested setup and conditions.
Can this mini-split run from a power station and solar? The demonstrated Rellytech 12,000BTU unit ran from a BLUETTI Elite 300 during the cooling test. Solar supplied part of the input while the battery covered the difference at high cooling demand. The displayed five-plus-hour runtime was an estimate, not a completed endurance test.
Exact setup and conditions
The video describes a Rellytech 12,000BTU, 120V-class mini-split and a BLUETTI Elite 300. Both the video description and the cached transcript at 0:19-0:24 identify two 590W panels; the exact panel revision is not established. The exact nameplate voltage has not been independently checked. The exact mini-split model code and hardware revisions are not available in the transcript, so match those details before using the result to choose equipment.
The test was in cooling mode on a hot day with smoke in the air. It does not establish winter heating performance. The video asks viewers whether they want a separate winter test.
| Observation | What it establishes | Evidence |
|---|---|---|
| 733W solar input | An instantaneous reading from this array in these conditions | Watch the source video |
| About 1,100W cooling demand | Power at the low temperature setting during the ramp-up test | Watch the source video |
| 738W concurrent solar input | Solar supplied part of that demand; the balance came from stored energy | Watch the source video |
| More than five hours displayed | A power-station runtime estimate with solar still arriving | Watch the source video |
Compare total cost and flexibility
The video gives historical prices of $399 before a 10% coupon for the mini-split and $1,011.08 after a coupon for the Elite 300. It also includes $500 for installation tools in its comparison, discusses shipping, and says the combined option costs more than the EG4 unit in that breakdown. These are video-era prices, not current offers or a complete installed quote.
A separate power station can store energy and power other compatible loads. That flexibility may be useful, particularly if you already own the power station. It does not prove this option is universally cheaper or more efficient than a solar hybrid mini-split. Compare panels, shipping, required installation, controls, usable storage and the exact competing model.
Limits before choosing equipment
Actual runtime changes with room heat gain, setpoint, weather, starting battery charge and solar availability. Use the manuals for the exact mini-split and power-station revisions, and have a qualified installer assess electrical and refrigeration requirements. The demonstrated wiring arrangement is not a general installation prescription.
