High-Voltage Solar Battery Charging Platform
At Ampernext, charging the battery of the microgrid is more than just electricity — it’s the backbone of reliable energy systems.
We design and deliver custom battery chargers for niche applications where reliability, scalability, and efficiency are critical. Powering industrial fleets, marine vessels, construction sites, microgrids, and next-generation mobility — fully customizable to your needs.
40kW High-Voltage Solar Battery Charger
The 40kW 1000V wallbox high-voltage solar battery charger / MPPT solar charge controller is a highly advanced and efficient solution for charging batteries from solar panels or any other DC source.
This all-in-pack solution features integrated electrical DC input and output protection and precharge and requires no external components to connect to the combiner box.
The charger also comes equipped with RS485, Ethernet, Wi-Fi, and 4G LTE connectivity options, allowing for easy integration and management by the control operator.
The energy management capabilities and connection protocols are directly transferred from the best industry practices 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.

Why Ampernext Chargers
Not all energy challenges are the same. Standard chargers often fail to meet the demands of industrial or remote environments. Our chargers are engineered to:
Designed for Off-Grid
Focusing over performance and simplicity, we engineer all-in-one DC-coupled battery charger products and solutions. No external components, inverters, converters or power supplies needed.Plug-and-Play Flexible Deployment
Simplified installation, and reduced costs. Integrate seamlessly into microgrids, off-grid systems, or complex infrastructure.- DC Source Agnostic
Couple it with any DC source – batteries, BESS, DC generators, solar panels, fuel cells, etc. Works with all battery chemistries, from Li-ion to supercapacitors.
- Modular & Scalable
Build systems that grow with your energy needs. Using our modular chargers, the whole system can be scaled at any time to meet different power levels. Start small, and grow indefinitely without heavy redesign.
- Broad Input DC Voltage
From 250V up to 950Vdc, suitable for almost all microgrids on the market.
- Broad Output Voltage
Output voltage from 150V up to 1000V, high-current, and optional bidirectional operation.
- Integrated Energy Management
Intuitive interface (10″ color display), data logging, and multiple communication (OCPP, Modbus, and CAN), for easy integration.
- AmperMate Cloud Server
Full visibility and dynamic control over the charging process. Remote monitoring, management, predictive diagnostics, analytics for full system oversight.
- Robustness and Durability
Designed for harsh environmental conditions, and even further customizable for extreme temperatures, dust, moisture, and rugged use.
