Inverter Sigenergy SigenStor EC 4.0 SP, 4kW/4,4kVA, hybrid, single phase, 2 MPPT - 10 years warranty

The Sigenergy SigenStor EC 4.0 SP 4 kW / 4.4 kVA single-phase hybrid inverter is a compact and intelligent solution designed for residential photovoltaic installations requiring efficient management of solar production, battery storage and self-consumption. Intended for professional installers, this energy controller integrates into the SigenStor ecosystem to manage power flows between photovoltaic panels, compatible battery storage, the grid and building loads. With a nominal power of 4 kW and an apparent power of 4.4 kVA, it is particularly suitable for medium-sized residential single-phase installations, single-family homes, solar extensions and self-consumption projects with regular energy needs. Equipped with 2 MPPT trackers, it can manage two solar panel orientations or two separate roof sections, improving production when modules are installed on different roof planes or exposed to varying sunlight conditions. Its hybrid technology allows surplus solar energy to be stored and used later when production decreases, especially in the evening or during peak consumption periods. The SigenStor EC 4.0 SP stands out for its modular and scalable architecture, designed to support both current and future residential energy needs. Its modern design, high efficiency, integrated communication and advanced protection features help secure the photovoltaic installation and simplify system operation. Compact and well suited to residential environments, it simplifies on-site installation and enables clear supervision through Sigenergy connected solutions. Ideal for self-consumption projects with storage, it provides clear added value compared with a conventional photovoltaic inverter by combining solar conversion, energy control and scalability within the same architecture. Backed by a 10-year warranty, the Sigenergy SigenStor EC 4.0 SP is a reliable, efficient and durable solution for modern single-phase photovoltaic installations.
