1. Introduction
The G-4510 series are M2M (Machine to Machine) Power Saving PAC with a cellular
transceiver and Solar Charger. It can be used in hydrologic monitoring or mudslide
monitoring system. With optional GPS model, the G-4510 can also be a GPS tracking
system for vehicle management system or maritime system.
The features of G-4510 series: Solar Charger, Ethernet interface, optional GPS
module, 3 digital inputs, 3 digital outputs, 8 analog inputs, 1 relay, 1 RS-232 and 1 RS-485
port. G-4510 can be used in various application fields to transfer data over 4G, 3G, GPRS,
SMS, Ethernet or serial bus through its optional 4G / NB communication module. The
G-4510 series built-in MiniOS7 provide the same development environment with
I-7188/I-7186 series. It is easier for I-7188/I-7186 users to apply the G-4510 series.

(2) Trigger U2_DI.(connect U2_DI to GND.; read U2_DI as 0)
(3) Make a phone call to G-4510
Deep Sleep Mode
This mode will shut down all interface, but exclude MCU2 I/O.
Power consumption：9~10 mA@12V
How to awake G-4510：
(1) Sleeping Time is finished.
(2) Trigger U2_DI.(connect U2_DI to GND.; read U2_DI as 0)

Low Voltage Protection
Default value is disabled, and you can enable this function by your program. This
function will prevent the battery to over-discharging. When the voltage of the battery is
less 11.1V, G-4510 will go into Low Voltage Protect Mode that will turn off all system
power. And then G-4510 will wake up if the voltage of the battery is over 12.6V after
charging.
Low Voltage disconnect Voltage = 11.1 V
Low Voltage reconnect Voltage = 12.6 V
How to use：please refer to the figure’s wire connection below, and MCU2 library
demo code.

5.2 How to Choose the Battery
This section will discuss how to choose a suitable battery for your system. Because the
alive time of the system is depending on your system power consumption and your battery
capacity, we will calculate with some conditions below.
Example 1：
Conditions：
The system has a 24V external power
It must work in 2 week when the external power is shut-down.
The system transmits the data to the server every 10 minutes. (1 minute for full work,
and 9 minutes for sleeping)
Power consumption of deep sleep mode is 7.2 mA@12V
Average power consumption of full work is 245 mA@12V
Calculation：
Average power consumption = 245 x (1/10) + 7.2 x (9/10) = 31 (mA)
31 (mA) x 24 (hours) x 14 (days) = 10416 mAh
We may choose “12V, 14Ah Lead Acid Battery” for this system.
Because 10% battery capacity is low battery voltage state, we don’t work in this state.
We use 90% battery capacity to calculate.
Double check the battery capacity：
14Ah x 90% x 1000 = 12600 mAh > 10416 mAh
We will choose a “12V, 14Ah Lead Acid Battery” for this system.

Example 2：
Conditions：
The system has a 24V external power.
It must work in 2 week when the external power is shut-down.
The system transmits 3 Modbus devices data to the server every 10 minutes. (1 minute
for full work, and 9 minutes for sleeping)
The system will power off all Modbus devices by “MCU2 Relay Output” when it’s
in Deep Sleep Mode.
Power consumption of deep sleep mode is 7.2 mA@12V
Average power consumption of full work is 424 mA@12V
Calculation：
Average power consumption = 424 x (1/10) + 7.2 x (9/10) = 49 (mA)
424 (mA) x 24 (hours) x 14 (days) = 16430.4 mAh
G-4510 Series User’s Manual v1.1.1
- 22/64 -
We may choose “12V, 22Ah Lead Acid Battery” for this system.
Because 10% battery capacity is low battery voltage state, we don’t work in this state.
We use 90% battery capacity to calculate.
Double check the battery capacity:
22Ah x 90% x 1000 = 19800 mAh > 16430.4 mAh
We will choose a “12V, 22Ah Lead Acid Battery” for this system.

5.3 How to Choose the Solar Panel
This section will discuss how to choose a suitable solar panel for your system. The
power of solar panel must be more than the power consumption of the system, and we will
calculate with some conditions below.
Things you must know before you calculate
Charging voltage：must be more than +16V
Max. Charge Current：2A
Sun hours：an average value. If the average daily solar radiation of the area is 3
kW/m2 , the sun hours of this area is 3 hours
Example：
Conditions：
Power consumption of deep sleep mode is 7.2 mA@12V
Average power consumption of the system is 245 mA@12V
The system transmits the data to the server every 10 minutes. (1 minute for full work,
and 9 minutes for sleeping)
Sun hours is 4 hours/day.
Using 10W solar panel
G-4510 Series User’s Manual v1.1.1
- 24/64 -
Calculation：
Solar panel Max. current = 10 (w) / 12 (V) = 0.833 (A) = 833 (mA)
Usually the charging current may be effected by many factor, like angle, building and
other environment factor…etc.
Here we use 1/2 Max. current to calculate
1/2 Max. Current = 833/2 = 416 mA
Average current = 416 x 4 / 24 = 69 (mA/hr)
Refer to Table 5.3.2, We can know “Average power consumption” is 31 mA for this
system. (refer to Table 5.3.2 or section 5.2)
We can know 10W solar Panel is suitable for this system, because 69 > 31

Things you must know about “sun hours”
Usually the “sun hours” is variable with the season. You need use the Min. sun
hours to calculate and choose the solar panel and the battery.
For example, if the sun hours of month is like the figure below, you must use 2.2
hours to calculate but not 6.7 hours.
