The \u003cstrong\u003eHV15 through HV50\u003c\/strong\u003e share a larger 615 × 465 × 255 mm die-cast housing rated IP66, have three MPPT inputs with up to six string inputs in total, accept a broader 100–800 V battery range, and deliver higher AC outputs suitable for commercial premises.

The Dura-i HV can charge the connected Dura5 HV batteries \u003cstrong\u003edirectly from the grid\u003c\/strong\u003e and manage discharge to offset peak import costs — no solar PV installation is required. This is particularly valuable for businesses on dynamic or time-of-use tariffs. When solar PV is added later, the inverter accepts up to 1,000 V DC string input across its MPPT channels without any hardware change, making retrofit straightforward.\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 Dura-i HV inverters can be connected in parallel?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 16px; background: #fff;\"\u003eUp to \u003cstrong\u003e30 Dura-i HV inverters\u003c\/strong\u003e can be paralleled in \u003cstrong\u003ePrimary–Secondary mode\u003c\/strong\u003e.

The \u003cstrong\u003eHV15 and HV30 use passive natural convection\u003c\/strong\u003e and produce a typical noise level of around \u003cstrong\u003e35 dB(A)\u003c\/strong\u003e — comparable to a quiet library. The \u003cstrong\u003eHV40 steps up to 55 dB(A)\u003c\/strong\u003e and the \u003cstrong\u003eHV50 to 60 dB(A)\u003c\/strong\u003e due to the active fan cooling required at those power levels. If the inverter is to be installed in or close to an occupied space (office, bedroom wall, etc.), the HV8–HV30 models are better suited; the HV40\/50 are designed for plant rooms, meter cupboards or outdoor enclosures where noise is less critical.\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;\"\u003eIs a G99 application required for the Dura-i HV?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 16px; background: #fff;\"\u003eYes — because all Dura-i HV models deliver more than 3.68 kW of AC output, a \u003cstrong\u003eformal G99 application to your Distribution Network Operator (DNO) is mandatory\u003c\/strong\u003e before commissioning any model in this range. DNO approval timescales typically run from \u003cstrong\u003e4 to 8 weeks\u003c\/strong\u003e, though this varies by network area. Your installer should submit the application early in the project to avoid commissioning delays.
