At locations without a fixed power supply, diesel generators are currently mainly used. The PowerCube was developed to ensure the power supply even without such a unit. The use with solar cells additionally offers the possibility to operate self-sufficient systems. * Flexible and versatile * High running time * Compensation of instable mains Features & Advantages * Display with charge status and load * Mains-independent power supply * Ambient temperature: 0°C to 40°C (up to 50°C with power loss) * Relative humidity 20% to 90% * Type of protection: IP21 * can be easily extended to a permanent power source with a solar panel via plug&play
