Overview
The all new and flexible 30kW 1000V wallbox battery charger with DC input and MPPT functionality is a highly advanced and efficient solution for providing battery charging at sites with installed solar panels and no AC grid available or DC-coupled installation with integrated battery energy storage.
This all-in-pack solution features integrated electrical DC input and output protections and precharge and requires no external components to connect to the DC grid. DC coupling is possible within minutes.
Equipped with Ethernet, Wi-Fi, and 4G LTE connectivity options, with in-built OCPP support, this DC coupled EV charger allows easy integration and management by any charging stations e-mobility operator.
The energy management capabilities and connection protocols are directly transferred from the best industry practices and protocols like Modbus, making it easy to be integrated into the modern complex DC grids with centralized control.
The high-quality 10” color display provides real-time information, making it user-friendly and easy to operate. Available for customization based on operators’ requests.

The DC microgrid corner
The constantly increasing demand for improved and sustainable electric power will result in higher stress over the existing AC electrical networks, while they will tend to stay limited because of the enormous capital investments needed to be done to align them to the coming requirements.
Our mission in Ampernext is to provide innovative solutions, products and technologies allowing rapid adoption of smart DC networks, microgrids, battery storage hubs and mixed AC-DC coupled grids.
Taking advantage of the latest technologies and best practices, our DC microgrid corner provides resources for this new revolution.
