Revolution in Energy Storage

Lithium battery technology is bringing a revolution in the field of energy storage for the years to come. LiFePO4 prismatic cells have outstanding characteristics when compared to any other battery technology.

Safe Operation –
The LifePO4 Cells are safe by design, eliminating the risk of thermal runaways.

Up to 3,500 Cycles at 80% DOD –
5 Times the number of cycles compared to Standard VRLA.

Long Service life –
LifePo4 prismatic cells are designed for 15-year service life, bringing it on par with NiCad battery solutions.

Low cost ownership –
LifePo4 prismatic cells are maintenance free and can over its lifetime store more energy than any battery technology.

CELNED 3C Controller

Designed and manufactured by TECNED BV, the Netherlands, a high-tech company specialized in power conversion, the CELNED 3C charge controller is made specifically with stationary applications in mind and facilitates smooth integration with AC & DC-UPS system.

Voltage Control
The CELNED 3C monitors the charge voltage and automatically stops charging when the optimal cell voltage is reached.

Cell Control
The CELNED 3C controller monitors individual cells for under/over voltage

Current Control
Integrated top-up charging ensures that all cells are charged correctly without unnecessary heat dissipation

The CELNED 3C charge controller is available fully integrated with all TECNED power assemblies. For 3rd party applications, the 3C charge controller is supplied in a wall mount cabinet, complete with LCD and fusing
