Liquid-cooled systems come with 415 VAC three-phase output as standard; a DC output, such as a 48 V telecom bus, can be configured.
Site derating 5%: 5.0 kW nameplate delivers 4.8 kW at 300 m and 45 °C.
How Umagine Hydrogen sizes it
| Peak load plus sizing margin | 4.4 kW 4.0 kW × 1.1 |
| Site derating | −5% 300 m altitude and 45 °C |
| Nameplate rating needed | 4.6 kW |
| Standard H2C0 modules | 1 × 5.0 kW Liquid-cooled series, 5 kW to 2 MW |

| Hydrogen a day | 1.71 kg at 14.0 kWh per kg |
| Usable hydrogen for 7 days | 12.0 kg 13.3 kg stored, 90% usable |
| Per cylinder | 0.70 kg 50 L at 200 bar, 25 °C, real gas |
Indicative sizing by Umagine Hydrogen (UHPL) for a first conversation, not a design. Output is derated by about 1% per 100 m above 1,000 m and 1% per °C above 40 °C; modules are picked from the standard H2C0 sizes. Hydrogen use assumes the average load for the hours given; cylinders are sized with real-gas (van der Waals) hydrogen at 25 °C. A detailed proposal needs your load profile, site data and hydrogen logistics, which is what the enquiry starts.
