Delivering 4 kW of nominal AC output power and supporting up to 8 kW of PV input power, it helps maximise solar self-consumption and reduce reliance on grid electricity. Two independent MPPT trackers optimise solar energy harvesting from different panel strings. Compatible with SigenStor BAT battery modules, the controller supports flexible energy storage and backup operation when paired with a compatible Sigen Energy Gateway and battery system. With a maximum efficiency of up to 98%, natural-convection cooling, and IP66-rated protection, the Sigen Energy Controller 4.0 SP is a reliable solution for residential solar and energy storage installations.\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003eMore information:\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0017\/8847\/7489\/files\/Sigenergy-Sigen-Energy-Controller-3_0-6_0-SP-Datasheet.pdf?v=1793179840\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0017\/8847\/7489\/files\/Sigenergy-Sigenstor-Home-Single-phase-System-3_0-6_0-Installation-Guide.pdf?v=1793180371\" target=\"_blank\"\u003eInstallation Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0017\/8847\/7489\/files\/Sigenergy-SigenStor-Limited-Warranty-Europe.pdf?v=1785402905\" target=\"_blank\"\u003eWarranty\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SolarTopStore.com","offers":[{"title":"Default Title","offer_id":55605520073031,"sku":"Energy Controller 4.0 SP","price":1125.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0017\/8847\/7489\/files\/Sigenergy-Sigen-Energy-Controller-4_0-SP.jpg?v=1793182147","url":"https:\/\/www.solartopstore.com\/products\/sigenergy-sigen-energy-controller-4-0-sp","provider":"SolarTopStore.com","version":"1.0","type":"link"}
