Product Overview
Description
The charge controller protects the battery from being overcharged
by the solar energy as well as from being overused by the loads.
The charging characteristics include several stages which include
automatic adaptation to the ambient temperatures.
System Voltage
This product is intended for use at 12 V and 24 V system voltage.
Battery Type
The ECO-N-T is suitable for use with lead acid batteries (vented,
GEL, or AGM type).
Low Voltage Disconnect Function
To prevent the battery against over-discharge this function
automatically switches off the load output at a battery voltage lower
than 11.0 V (12 V systems) or 22.0 V (24 V systems). As soon as
the battery reaches a voltage of 12.8 V (12 V systems) or 25.6 V
(24 V systems), the load output is switched on again.
Regulatory Information
Operation Notes
Warning: Indicates high voltage. Use caution when
performing task.
Caution: Indicates a critical procedure for safe operation.
Note: Indicates important information for safe and easy
installation and operation.

Warnings & Safety Instructions
Please read the instructions and warnings in this manual before
beginning installation.
Please do not disassemble or attempt to repair Phocos products.
Phocos charge controllers do not contain user serviceable parts.
High Voltage Risks
Operation of this device may produce a high voltage which could
cause severe injuries or death in case of improper installation or
operation of this device.
Do not touch any electrical conductors to avoid electrical shock.
Never work on live (energized) electrical equipment.
When working around a battery, do not allow tools to bridge the
battery terminals or short circuit any part of the battery.
Use only tools that have insulated handles.
PV modules can generate high DC voltages!
Mains and Charging Current Risks
Make sure the cables are always connected to the correct terminal.
An electrical shock can be lethal.
It is important the battery receives a full charge at least weekly. If
not, the battery will get permanently damaged. The battery cannot
receive a full charge if the loads are too large for the system.

6
Display Functions
The controller is equipped with 3 LEDs to display the operating
status.
In normal operation, the controller shows the charging status, the
battery SOC status and the load output status.

When the battery voltage is indicated as low, it is recommended to
use the remaining energy economically.
The charge controller will subsequently turn off the load.
In case of deep discharge or overload/short circuit of load, the load
output is switched off. This is indicated by:
Battery voltage > 12V
12V >Battery voltage > 11.5V
11.5V >Battery voltage > 11V

Installation Instructions
Before you Begin
The controller is intended for indoor use only.
Protect the controller from direct sunlight and place it in a dry
environment.
The controller and battery must be installed in the same room.
The controller warms up during operation; be sure it is installed on a
non-ammable surface.
Connect the Controller
Please verify that all the cable/wire connections are made properly
and well insulated so that no water or humidity can get in. This
avoids any bad or loose connections that would result in excessive
heating or further damage.
1. *Connect the battery to the charge controller; Positive
(+) & Negative (-).
2. Connect the solar modules to the charge controller;
Positive (+) & Negative (-).
3. Connect the load to the charge controller; Positive (+)
& Negative (-).
*Phocos strongly recommends installing an inline fuse as
close to the battery terminal as possible.
See illustrated steps on opposite page.
