The inverter features 14 independent MPPTs, each supporting up to 2 PV strings thanks to the high levels of current supported, for a total of 28 strings connectable.<\/p>\n<p>On the AC side, the Sigen PV 370H2 delivers a rated output power of 333.000 W, while the Sigen PV 400H2 delivers a rated output power of 360.000 W, both with an output voltage of 800 V (3W+PE). Maximum efficiency reaches 99%, with a European efficiency of 98.8%.<\/p>\n<p>Built-in safety functions include a DC switch, PV\/output terminal overtemperature protection, anti-islanding protection, AC overcurrent protection, DC reverse-polarity protection, insulation monitoring, and residual current monitoring. DC surge protection is Type II as standard (Type I optional), while AC surge protection is Type II; arc-fault detection (AFCI) is available as an option.<\/p>\n<p>The inverter can operate within an ambient temperature range from -30 \u00b0C to 60 \u00b0C, has an IP66 protection rating and a smart air cooling system. The anti-corrosion class is C5-M as standard (C5-H optional). Dimensions do not go over half a cubic meter, with a weight of 150 kg.<\/p>\n<p>It communicates via Fast Ethernet, AC-side power line communication (PLC) and WLAN. The management is performed through a dedicated app and an integrated LED display.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Three-phase multi-MPPT string inverter Sigenergy Sigen PV 370H2 and 400H2, designed for utility PV installations.<\/p>\n<ul>\n<li>Rated power 333.3 and 360kW kW<\/li>\n<li>14 independent MPPTs<\/li>\n<li>European efficiency 98.8%<\/li>\n<li>AC output 800 V<\/li>\n<\/ul>\n","protected":false},"featured_media":89429,"template":"","meta":[],"product_brand":[],"product_cat":[10176,10180],"product_tag":[11259,11257,11258,11260,11263,11261,11254,11264,11265,11266,10293,11253,11255,11256,11262],"class_list":{"0":"post-89430","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-sigenergy-inverter-en","7":"product_cat-commercial-inverter-sigenergy","8":"product_tag-1500-v-inverter","9":"product_tag-333-kw-inverter","10":"product_tag-360-kw-inverter","11":"product_tag-800-v-inverter","12":"product_tag-ground-mounted-pv-systems","13":"product_tag-multi-mppt-inverter","14":"product_tag-pv-inverter","15":"product_tag-sigen-pv-370h2","16":"product_tag-sigen-pv-400h2","17":"product_tag-sigen-utility-pv-inverter","18":"product_tag-sigenergy-en","19":"product_tag-sigenergy-inverter","20":"product_tag-string-inverter","21":"product_tag-utility-scale-inverter","22":"product_tag-utility-scale-solar","24":"first","25":"instock","26":"shipping-taxable","27":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.7 -
