Technical DataProduct Introduction
Phocos’ ECO-N-T is a cost effective solution for many challenging
solar applications. Its compact size allows it to fit well in small spaces.
The industrial grade ECO-N-T is fully encapsulated, which protects
the circuit board from corrosion. This unit also features UL and
other certifications, proving it is a robust charge controller that will
perform well in a variety of harsh environments.
The ECO-N-T is versatile and offers the flexibility of operating with
12 or 24 V systems. This reliable charge controller is simple to use,
as it requires no user programming and has easy to interpret LEDs.
The ECO-N-T will protect your batteries from overcharging and over
discharging, making for a strong return on investment.
