Go Power GP-PC-10/IP68 Potted PWM Solar Controllers User Manual

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

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

NOTE: Indicates important information for safe and easy installation and operation. 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.

Please read the instructions and warnings in this manual before beginning installation.

Please do not disassemble or attempt to repair Go Power! products. Go Power! charge controllers do not contain user serviceable parts.

WARNINGS & SAFETY INSTRUCTIONS

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.

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.

CHARGE DISPLAY

CHARGE DISPLAY

Controller connected to battery, night detected
(Green LED on)
Controller connected to battery, day detected
(Green LED flashes)
No battery detected
(Green LED off)

BATTERY SOC DISPLAY

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.

OK (Yellow LED off) Battery voltage > 12V

Low (Yellow LED off) 12V > Battery voltage > 11.5V

Very Low (Yellow LED flashes) 11.5V > Battery voltage > 11V

LOAD STATUS DISPLAY

In case of deep discharge or overload/short circuit of load, the load output is switched off. This is indicated by:

Normal operation (Red LED off)

Low/high voltage disconnect (Red LED on)

Overload or short circuit of load (Red LED flashes).

INSTALLATION INSTRUCTIONS

BEFORE YOU BEGIN

Note

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- flammable 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.

*Connect the battery to the charge controller; Positive (+) & Negative (-).
Connect the solar modules to the charge controller; Positive (+) & Negative (-).
Connect the load to the charge controller; Positive (+) & Negative (-).

*Go Power! strongly recommends installing an inline fuse as close to the battery terminal as possible. See illustrated steps on the following page.

SAFETY FEATURES

SAFETY FEATURES	PV TERMINALS	BATTERY TERMINALS	LOAD TERMINALS
Reverse Polarity	Protected	Protected: Red LED on	Protected (1)
Short Circuit (2)	Protected	Protected (3)	Switches off immediately
Overcurrent	—–	—–	Switches off with a delay (4)
Reverse Current	Protected	—–	—–
Overvoltage	50V	31V	Switches off above 15.5/31V
Undervoltage	—–	—–	Switches off
Overtemperature	Reduces the charging current if overtemperature occurs and

switches off the load if the temperature reaches a higher level.

Controller can protect itself, but any connected loadsmight be damaged.
Short circuit: >4x – 6x nominal current
Battery must be protected by a fuse, or it might be permanently damaged in case of short circuit.
200% nominal current disconnect with 3s delay.

ERROR CODES

WARNING

The combination of multiple error conditions may cause damage to the controller. Always remove the fault condition before you begin connecting the controller!.

Error
