Up to \u003cstrong\u003e30 Dura-i HV inverters\u003c\/strong\u003e can be paralleled in a single system, scaling maximum usable storage to approximately \u003cstrong\u003e2.2 MWh\u003c\/strong\u003e — suitable for commercial facilities, large agricultural premises and light-industrial sites.

Unlike nickel manganese cobalt (NMC) cells — which are more energy-dense but release oxygen during thermal runaway — LiFePO₄ does not propagate fire in the same way, making it the preferred choice for large commercial battery installations, indoor environments and locations close to occupied spaces. The trade-off is slightly lower energy density, meaning LiFePO₄ packs are physically larger per kWh than NMC equivalents. The Dura5 HV's \u003cstrong\u003eself-extinguishing cell design\u003c\/strong\u003e and integrated fire suppression build on this inherent chemistry advantage with additional active protection layers.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #d0ece9; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #fff; padding: 13px 16px; font-weight: bold; cursor: pointer; list-style: none;\"\u003eCan the Dura5 HV operate in an unheated outbuilding or outdoor enclosure?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 16px; background: #fff;\"\u003eYes — the Dura5 HV is rated for operation down to \u003cstrong\u003e−10 °C\u003c\/strong\u003e without internal heaters, which is sufficient for most UK external and unheated-building installations. Its \u003cstrong\u003eIP65 ingress protection\u003c\/strong\u003e guards against dust and water spray. However, if the installation site regularly experiences temperatures below −10 °C (highland Scotland, high-altitude sites), performance will derate and the module should not be operated outside its rated range. Always ensure the enclosure provides adequate ventilation for the natural convection cooling to function correctly — do not seal the unit airtight.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #d0ece9; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #fff; padding: 13px 16px; font-weight: bold; cursor: pointer; list-style: none;\"\u003eHow many Dura5 HV modules do I need for my site?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 16px; background: #fff;\"\u003eSizing depends on your \u003cstrong\u003edaily energy consumption, peak demand, backup duration requirements and solar generation profile\u003c\/strong\u003e. As a rough guide: a 5.12 kWh module (4.6 kWh usable) covers approximately one hour of backup for a site drawing 4–5 kW continuously. For commercial sites, the more useful starting point is calculating your \u003cstrong\u003eovernight import volume\u003c\/strong\u003e (if using off-peak charging) or your \u003cstrong\u003epeak demand offset target\u003c\/strong\u003e (if the primary goal is demand charge reduction).
