Eaton ASC48-ES solar charger

Compliant with international standards, the Eaton ASC48-ES solar charger is designed for communications network operators who are seeking to cut energy costs or are required to meet carbon footprint reduction targets.

The solution uses the company’s range of modular power building blocks and power chassis. Key features include a maximum power point tracking (MPPT) function that can extract the maximum possible power from the solar panels. In addition, the solar charger features intelligent digital signal processing for enhanced control, producing peak efficiency in excess of 96% for typical operating loads, while also maintaining a very high minimum operating efficiency of 95 to 96%, over a wide range of loads (from 30 to 100% of the 2 kW capacity).

Users also benefit from combining the ASC48-ES with the Eaton SC200 controller, providing a fully managed solution. Full monitoring includes energy metering and logging on input and output.

The charger is also fully compatible with existing 3G systems, including the Eaton APS3 and APS6 systems. The output may be paralleled with one or two more rectifiers to produce a versatile power solution for both AC or generator power and solar power. This makes it suitable for a fully integrated solar/diesel hybrid solution, or an AC-powered system with solar added to reduce energy consumption.

Intelligent control in the SC200 allows optimal balance of solar energy and back-up fuel. The solar charger is protected against input overvoltage, surges and overtemperature. It is rated for operation in temperatures at up to 70°C.
