The 4.6 kW FoxEss AC charger provides maximum flexibility and efficiency to improve the operation of residential or commercial photovoltaic installations. The device enables integration with battery storage systems, increasing its utility. It can be used as an integral part of a new installation. The charger is connected to the AC grid alongside the inverter, and after communicating with metering devices, its operation can be fully programmed. It is designed to work in several modes, including as a UPS (in case of total grid failure), supplementing the system when power demand exceeds PV generation capabilities, or absorbing excess energy produced by the inverter to maintain proper AC grid voltage conditions. \n \n Market-leading overall efficiency, offering up to 97% AC-to-battery discharge efficiency. Compatible with the latest high-voltage lithium-ion batteries. IP65 protection – a durable enclosure allowing for indoor or outdoor installation. Remote system monitoring. FOX storage kits come with an advanced and intuitive mobile app, enabling remote management and operation monitoring. Natural cooling, high temperature tolerance, and the absence of noisy internal fans ensure both safety and quiet operation.
