It is designed for three-phase grids with a rated output voltage of <strong>800 V<\/strong>.<\/p>\n<p>The <strong>Sigen PV 370H2<\/strong>, on the other hand, provides a rated active power of <strong>333.3 kW<\/strong> and a maximum apparent power of <strong>366.3 kVA<\/strong>, while retaining the same DC architecture and AC voltage.<\/p>\n<p>On the DC side, both inverters feature:<\/p>\n<ul data-spread=\"false\">\n<li><strong>14 independent MPPT trackers<\/strong>;<\/li>\n<li><strong>2 strings per MPPT<\/strong>, for a total of 28 DC inputs;<\/li>\n<li>maximum input current of <strong>40 A per MPPT<\/strong>;<\/li>\n<li>short-circuit current of <strong>60 A per MPPT<\/strong>;<\/li>\n<li>maximum input voltage of <strong>1,500 V<\/strong>;<\/li>\n<li>MPPT operating range from <strong>480 to 1,500 V<\/strong>;<\/li>\n<li>start-up voltage of <strong>520 V<\/strong>;<\/li>\n<li><strong>H4 Pro connectors<\/strong> for direct string connection.<\/li>\n<\/ul>\n<p>These characteristics make the Sigen PV 370H2 and Sigen PV 400H2 particularly suitable for the design of <strong>large-scale photovoltaic plants based on a 1,500 V DC architecture<\/strong>.<\/p>\n<h2>14 MPPTs and 28 strings for high-current PV modules<\/h2>\n<p>One of the key features of the new Sigenergy inverters is their architecture with <strong>14 independent MPPTs and 28 string inputs<\/strong>.<\/p>\n<p>The maximum current of <strong>40 A per MPPT<\/strong> allows two parallel strings of PV modules with G12 cells to be connected, whose current at maximum power point can typically range between 17 and 19 A.<\/p>\n<p>This makes it possible to use all 28 inputs even with <strong>high-power, high-current PV modules<\/strong>, an increasingly important consideration when designing large-scale PV plants.<\/p>\n<p>The 14 independent trackers also provide greater flexibility when managing array sections with <strong>different orientations, tilt angles or operating conditions<\/strong>.<\/p>\n<p>This can be particularly useful in utility-scale PV plants installed on non-uniform terrain, helping to limit mismatch losses. For this architecture, Sigenergy states a <strong>yield increase of up to 1.5% based on simulations<\/strong>.<\/p>\n<h2>Why choose Sigen PV 400H2 for MW-scale PV plants<\/h2>\n<p>With <strong>360 kW of rated power per inverter<\/strong>, the Sigen PV 400H2 can reduce the overall number of units required in large-scale photovoltaic plants.<\/p>\n<p>As an indication, approximately the following number of inverters would be required to achieve 10 MW of rated power:<\/p>\n<ul data-spread=\"false\">\n<li><strong>28 Sigen PV 400H2 units<\/strong>;<\/li>\n<li><strong>30 Sigen PV 370H2 units<\/strong>.<\/li>\n<\/ul>\n<p>The ability to connect <strong>28 strings directly to each inverter<\/strong> may also reduce the need for string combiner boxes in certain system configurations, decreasing the number of terminations and potential points of failure.<\/p>\n<p>The result is a potentially simpler array architecture, with benefits during both installation and subsequent maintenance activities.<\/p>\n<h2>800 V AC output: advantages for large-scale PV plant design<\/h2>\n<p>Another relevant feature of the <strong>Sigen PV 370H2 and Sigen PV 400H2<\/strong> is their three-phase output with a rated voltage of <strong>800 V AC<\/strong>.<\/p>\n<p>The Sigen PV 400H2 has a rated output current of <strong>259.9 A<\/strong>. At the same power level, using a higher voltage than traditional 400 V architectures makes it possible to reduce the current on the AC side.<\/p>\n<p>For designers and EPC contractors, depending on the plant configuration, this can translate into <strong>smaller conductor cross-sections, reduced losses and optimised AC distribution<\/strong> between the inverters and transformer substation.<\/p>\n<p>However, the system design must include a <strong>transformer with a low-voltage winding compatible with the 800 V output<\/strong>.<\/p>\n<h2>Protection and safety features of Sigen PV 370H2 and 400H2<\/h2>\n<p>For utility-scale photovoltaic plants, operational continuity and equipment protection are essential factors.<\/p>\n<p>The Sigen PV 370H2 and Sigen PV 400H2 include the following as standard:<\/p>\n<ul data-spread=\"false\">\n<li>DC switch;<\/li>\n<li>DC reverse-polarity protection;<\/li>\n<li>PV and output terminal overtemperature protection;<\/li>\n<li>anti-islanding protection;<\/li>\n<li>AC overcurrent protection;<\/li>\n<li>insulation monitoring;<\/li>\n<li>residual current monitoring;<\/li>\n<li><strong>Type II SPDs on both the DC and AC sides<\/strong>.<\/li>\n<\/ul>\n<p>Both inverters also feature an <strong>IP66 protection rating<\/strong>, intelligent air cooling and an operating temperature range from <strong>\u221230\u00b0C to +60\u00b0C<\/strong>.<\/p>\n<p>These characteristics make them suitable for outdoor installation under the typical operating conditions of large ground-mounted photovoltaic plants.<\/p>\n<h2>Fault diagnostics and reduced O&amp;M costs<\/h2>\n<p>In large-scale PV plants, system availability and the speed of maintenance operations have a direct impact on investment profitability.<\/p>\n<p>For the Sigen PV 370H2 and Sigen PV 400H2, Sigenergy states an <strong>MPPT-level insulation fault localisation function<\/strong>, with a claimed resolution up to 15 times higher.<\/p>\n<p>In the event of an alarm, the system can therefore identify which of the <strong>14 MPPTs<\/strong> is affected by the fault.<\/p>\n<p>For O&amp;M personnel, this means that troubleshooting can be narrowed down to a smaller section of the PV array connected to the inverter, potentially reducing the time required to identify the fault.<\/p>\n<p>In utility-scale plants comprising dozens of inverters, more granular diagnostics can contribute to <strong>reducing downtime and Operation &amp; Maintenance costs<\/strong>.<\/p>\n<h2>Communication and monitoring<\/h2>\n<p>In terms of communication, the Sigen PV 370H2 and Sigen PV 400H2 support:<\/p>\n<ul data-spread=\"false\">\n<li><strong>Fast Ethernet<\/strong>;<\/li>\n<li><strong>PLC (Power Line Communication)<\/strong> over the AC line;<\/li>\n<li><strong>WLAN<\/strong> for configuration via the app;<\/li>\n<li>LED indicators for operating status display.<\/li>\n<\/ul>\n<p>PLC communication allows the AC power line to be used for data transmission as well, reducing the need for dedicated communication infrastructure in certain configurations.<\/p>\n<p>The preliminary datasheet used as a reference does not, however, specify an <strong>RS485<\/strong> port.<\/p>\n<h2>Sigen PV 370H2 and 400H2 and the Central Plant Controller<\/h2>\n<p>For large photovoltaic plants connected to the medium-voltage grid, the requirements established by Italian regulations for the <strong>Central Plant Controller (Controllore Centrale d\u2019Impianto \u2013 CCI)<\/strong> must also be taken into account.<\/p>\n<p><strong>ARERA Resolution 385\/2025\/R\/EEL<\/strong> regulates the installation of the CCI and PF2 functionalities for active power regulation following commands from the Distribution System Operator, in accordance with the thresholds, deadlines and procedures established by the applicable regulations.<\/p>\n<p>With the <strong>Sigen PV 370H2 and Sigen PV 400H2, the CCI remains an external device<\/strong> and must therefore be taken into account within the overall plant architecture.<\/p>\n<p>For further information on requirements, power thresholds and deadlines, see our dedicated article on <strong><a href=\"https:\/\/www.vpsolar.com\/cci-delibera-arera-385-2025\/\">ARERA Resolution 385\/2025 and the Central Plant

choose?<\/h2>\n<p>The choice between the two models mainly depends on the <strong>plant capacity, planned electrical architecture and DC\/AC ratio sizing<\/strong>.<\/p>\n<p>Thanks to its 360 kW rated power, the <strong>Sigen PV 400H2<\/strong> allows more power to be concentrated in each individual inverter and may therefore be particularly suitable for large utility-scale plants where optimising the number of installed inverters is a key objective.<\/p>\n<p>The <strong>Sigen PV 370H2<\/strong>, with a rated power of 333.3 kW, retains the same configuration of 14 MPPTs and 28 DC inputs, while offering greater flexibility in system configurations where this power rating is better suited to the overall plant design.<\/p>\n<p>In both cases, the combination of <strong>1,500 V DC architecture, 800 V AC output, 14 MPPTs, compatibility with high-current PV modules and advanced diagnostics<\/strong> positions the new Sigenergy inverters as solutions specifically designed for <strong>large-scale utility and C&amp;I photovoltaic plants<\/strong>.[vc_row][vc_column]<div class=\"woocommerce\">\t\t\t<div class=\"single-product\"
