• Outstanding system efficiency (max. 98%) thanks to integrated Maximum Power Point Tracker technology (MPPT)
• Maximizes power output & reduces system costs
• IP68 casing, IP21 terminals
• Compatible with 60-cell PV modules
• 12/24 V DC systems

General Safety Information

This manual contains important installation, set up, and safety operating instructions.
Please read the instructions and warnings in this manual carefully before beginning any installation.
Please do not disassemble or attempt to repair Phocos products. Phocos’ charge controllers do not contain user serviceable parts.
Please observe all instructions with regard to external fuses/breakers as indicated.
The information contained in this manual must be observed in its full extent. The manual contains information regarding installation, set up, and operation.
Please read this manual carefully before using the product, and pay special attention to the safety recommendations in it.

Maintenance and installation notes

When installing or working on the PV system, please disconnect the PV (solar) modules from the charge controller first, to prevent any damages to the charge controller!
Please verify that all cable/wire connections are done properly and are well insulated and that no water or humidity can ingress in order to avoid any bad or loose connections that would result in excessive heating or further damage.
Please install a fuse or breaker near the battery before installing or adjusting the controller!
When connecting inductive loads (motors, relays, etc.) a freewheel diode must be connected in parallel to the loads in the reverse biased direction.

High voltage risks

Never 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 with insulated handles.
Operation of this device may produce a high voltage which could cause severe injuries or death in case of improper installation or operation of the device.
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. In general, any electric shock can be dangerous to your health.

CE labeling

The product is CE compliant.

Connecting and Grounding

The controller is intended for indoor use only. Protect it from direct sunlight and place it in a dry environment. Never install it in humid rooms (like bathrooms). The controller warms up during operation, and should therefore be installed on a non flammable surface only.

• Connect wires in indicated order 1 2 3 4 5 6 to avoid any installation faults
• To avoid any damaging voltage on the wires, first connect the wire to the controller, then to the battery, to the panel or to the load
• Minimum recommended wire size: 4 mm²
• Make sure the wire length between battery and controller is as short as possible
• Be aware that the negative terminals of the ECO-N-MPPT 85/15 are connected together and therefore have the same electrical potential. If any grounding is required, always do this on the negative wires.
• When connecting inductive loads (motors, relays, etc.) a freewheel diode must be connected in parallel to the loads in the reverse biased direction.
• Inverters should always be connected directly to the battery due to their high inrush currents.

Starting up the controller

Self Test

As soon as the controller is supplied with power from the battery, it starts a self test routine. Then the display changes to normal operation.

System Voltage

The controller adjusts itself automatically to 12 V or 24 V system voltage. As soon as the voltage at the time of start-up exceeds 18 V, the controller assumes a 24 V system. If the battery voltage is not within the normal operation range at start-up, a status display according to the section ERROR DESCRIPTION occurs.

Battery Type

The ECO-N-MPPT 85/15 has no equalization charge and is therefore suitable for lead-acid batteries with liquid electrolyte (vented batteries) and leadacid batteries with solid electrolyte (GEL or AGM batteries). In case of any doubts consult your local dealer.

Safety Features

urs and switches off **** the load if the temperature reaches a high level.

1. Panels are short circuited by diodes. The controller can therefore only be subjected to these conditions for a limited time. A battery connected to the panel terminals in reverse polarity will instantly cause a damage to the controller.
2. A battery fuse is necessary to protect the ECO-N-MPPT 85/15 from getting damaged by reverse polarity connection on the battery terminals.
3. The controller can protect itself, but any connected loads might be damaged.
4. Short-circuit: >3x – 20x nominal current.
5. The battery must be protected by a fuse, or it might be permanently damaged in case of short-circuit.

6. 200% nominal current: disconnects with 3s delay,

7. MPPT switches off when detecting reverse current.
8. At voltages above 85 V the MPPT will stop charging.
   WARNING: The combination of different error conditions may cause damage to the controller. Always remove the fault condition before you continue connecting the controller!

Low Voltage Disconnect Function (LVD)

The charge controller is equipped with a low voltage disconnection function to protect the battery against a deep discharge: This function is controlled by the voltage, and automatically switches off the load output at a battery voltage lower than 11.0/22.0 V. As soon as the battery reaches a voltage of 12.8/25.6 V, the load output is switched on again.

Note: Battery voltage must be below adjusted setting for longer than 2 minutes before LVD occurs.
Note: Voltage levels before/after the slash are valid for 12 V and 24 V systems respectively (valid for the charge controllers presented in this manual).
