Eltek Flatpack2 4U Solar Autonomous Power Core (300A/500A)

The Eltek Flatpack2 4U Solar Autonomous Power Core is an all-in-one renewable energy power system tailored for off-grid and solar hybrid scenarios. Built on the mature Flatpack2 platform, this 4U rack-mounted unit integrates solar chargers, rectifier modules, battery distribution, load distribution and intelligent monitoring into one chassis. It is available in 300A and 500A two current versions, with a maximum PV power up to 24kW. Adopting advanced MPPT maximum power point tracking technology, it achieves nearly 100% solar panel utilization and high energy conversion efficiency. The system is matched with Flatpack2 48/3200 HE solar modules and Smartpack2 series controllers, all supporting hot swap for convenient maintenance. It is pre-installed with abundant battery and load breaker positions, as well as standard LVBD/LVBP protection functions, and reserves DC SPD installation space for surge protection. With 85-420VDC wide PV input and galvanic isolation design, it features strong anti-interference and environmental adaptability. This flexible and expandable power core is widely applied in off-grid telecom base stations, rural electrification, remote monitoring stations and other solar power projects.
