ok, please do free laundry at noun o clock

> 1. Grid-first operation: The laundromat primarily runs on public power. The inverter is a backup and support system, not the main energy source.
>
> 2. Purpose of the inverter: It exists to complete ongoing wash cycles during outages, protect equipment, and avoid service disruption not to power full operations continuously.
>
> 3. Sustainability over size: Installing a very large inverter and solar system upfront would create costs that current and near-term revenue cannot maintain, increasing long-term risk.
>
> 4. Break-even focused: The system is intentionally sized to reach early break-even, ensuring the business can sustain operations, maintenance, and replacements.
>
> 5. Phased growth: Power capacity will be upgraded only when revenue justifies it, using real operational data rather than theoretical maximum load assumptions.
>
> 6. Responsible capital use: Buying infrastructure that cannot be maintained over the next 5 years contradicts sound business practice.
>
> 7. Start small, scale smart: The project prioritizes consistency, resilience, and long-term viability over maximum upfront specifications.

> > 5–7.5kVA inverter is roughly 4–6 kW usable continuous power

> > One listing for this class of Hisense 10.5/6kg washer-dryer shows ~305 kWh per 100 cycles for wash+dry versus ~52 kWh per 100 cycles for wash-only.
> >
> > Even if you never use heated drying, 6 machines running together + motor surges + pumps + control electronics can already push a 5–7.5kVA setup into brownout/overload territory.
> >
> > A 5kVA system is undersized, and 7.5kVA leaves no margin.

> > Notes: (looks like you need ~5x setup)

> > - Required inverter (continuous): ~18–20 kW
> > That’s roughly 22–25 kVA (depending on power factor).
> >
> > - Realistic battery range with dryers in use: ~30–60 kWh
> >
> > - With dryers in real use: ~11–22 kW of panels
> > If panels are 450W each:
> > 11.2 kW ≈ 25 panels
> > 16.8 kW ≈ 38 panels
> > 22.4 kW ≈ 50 panels

> > Conclusion
> >
> > If dryers are used as advertised, you’re looking at roughly:
> > ~22–25 kVA inverter, ~30–60 kWh battery, ~11–22 kW solar PV (depending on cycles/day).
> >
> > The proposal specifies:
> > 5–7.5 kVA inverter, 10–15 kWh battery, 10 panels, with no load control plan.
