Remote security projects in the Middle East often face one practical challenge before the cameras even start working: stable power supply.
For CCTV cameras, PoE switches, wireless bridges, routers, Starlink terminals, monitoring sensors and other security equipment, the installation site is often far from reliable grid power. In desert, oilfield, construction, highway, border, farm or temporary surveillance sites, the power system must be compact, stable, easy to maintain and suitable for outdoor project deployment.
This article introduces a 25.6V 100Ah solar power system wiring layout designed for remote security and surveillance applications. The system is suitable for project-based customization where the load, backup time, output voltage and installation environment need to be confirmed before final design.
Why Security Projects in the Middle East Need a Dedicated Solar Power System
Many security integrators and project contractors cannot simply use a standard consumer solar kit for remote CCTV sites. Security projects usually require continuous operation, stable DC output, clear protection design and simple field maintenance.
In Middle East applications, the power system may need to deal with:
High ambient temperature, dust and outdoor exposure.
Long-distance installation sites without stable grid power.
Multiple voltage outputs such as DC 24V, DC 12V, DC 48V or AC 220V.
Continuous operation for cameras, PoE switches and communication equipment.
Maintenance by local installation teams, not factory engineers.
For this reason, the internal wiring layout is important. A clean electrical structure reduces installation mistakes and makes future inspection easier.
System Overview: 25.6V 100Ah Solar Power Supply
The system shown in the wiring layout uses a 25.6V 100Ah LiFePO4 battery platform. The nominal battery energy is about 2.56kWh, and the actual usable energy depends on the battery settings, depth of discharge, load power and site temperature.
A typical configuration can include:
25.6V 100Ah LiFePO4 battery pack.
MPPT solar charge controller.
PV input terminal.
DC surge protection device.
PV DC breaker or isolator.
Battery main fuse.
Battery isolator switch.
Positive and negative busbars.
Small load fuse box.
DC 24V main output.
DC 24V to 12V DC/DC converter.
DC 24V to 48V DC/DC converter.
AC charger input for hybrid or backup charging.
24V to AC 220V inverter if AC output is required.
PE grounding bar for metal enclosure safety.
This structure is suitable for small and medium security loads. For larger camera stations, Starlink communication systems or multi-device surveillance platforms, the battery capacity and solar panel power can be increased according to the actual load list.
Optimized Wiring Layout for Project Reliability
The wiring layout is divided into clear functional areas:
PV input area.
Charge control area.
Battery connection area.
Central busbar area.
Small load distribution area.
AC input area.
Charger area.
Inverter area.
AC output area.
This zoned layout helps separate DC and AC circuits, reduce wiring confusion and make the system easier to assemble in production.
The positive and negative busbars are placed in the center of the system. This allows branch circuits to be distributed clearly from one point, instead of creating messy parallel connections across different devices. For project delivery, this is especially useful because installers can quickly identify where each circuit starts and where it is protected.
Protection Design for Outdoor Security Equipment
For CCTV and remote monitoring projects, protection design should not be ignored. A low-cost system without clear protection may work during testing, but it can create problems after installation.
The recommended protection design includes:
DC surge protection on the PV input side.
PV DC breaker or isolator for maintenance.
Main battery fuse close to the battery output.
Battery isolator switch for safe service.
Branch fuse protection for each small load.
AC input breaker and RCD for charger input.
AC output breaker for inverter output.
Reliable PE grounding for metal enclosures and AC equipment.
This design is not only for safety. It also helps reduce after-sales issues because faults can be isolated by circuit instead of affecting the entire system.
Suitable Loads for Middle East Security Applications
This type of solar power system can be customized for many remote security loads, including:
CCTV security cameras.
AI surveillance cameras.
PoE switches.
Wireless bridge equipment.
4G or LTE routers.
Starlink or other satellite communication terminals.
Remote monitoring sensors.
Small control cabinets.
Temporary construction site security systems.
Oilfield and pipeline monitoring points.
For each project, the most important step is to confirm the real power consumption of every device. Camera peak power, PoE switch consumption, router power and communication equipment duty cycle all affect the final solar and battery sizing.
DC 24V, 12V and 48V Output Options
Many security projects use more than one voltage. For example, some cameras may need 12V DC, the main system may run on 24V DC, and communication devices or PoE equipment may require 48V DC.
A 25.6V battery system can support different outputs through DC/DC converters:
DC 24V main output for standard system loads.
DC 24V to 12V output for 12V cameras or routers.
DC 24V to 48V output for PoE or communication equipment.
AC 220V output through an inverter when AC equipment is required.
For project stability, each output branch should have independent fuse protection. This prevents one faulty device from affecting the whole power system.
Why This Layout Is Better for Project Delivery
For system integrators and security contractors, the power cabinet must be easy to install, inspect and maintain. A clean internal layout gives several advantages:
Faster assembly in production.
Lower risk of wiring mistakes.
Easier troubleshooting on site.
Clearer separation between AC and DC circuits.
Better appearance for customer inspection.
More professional project documentation.
For Middle East security projects, where sites may be far away from the supplier or installation team, these details directly affect project reliability and after-sales cost.
Customization Options for Different Security Projects
The 25.6V 100Ah system is only one reference platform. The final configuration can be customized based on:
Installation country and city.
Average load power.
Peak load power.
Required backup time.
Solar panel installation space.
Daytime and nighttime operating mode.
Output voltage requirements.
Enclosure size and IP rating.
Communication equipment type.
Need for AC backup charging.
Need for remote monitoring or RS485 communication.
For example, a small single-camera site may use a compact battery and solar panel configuration. A multi-camera site with PoE switch and wireless communication may require larger battery capacity and a stronger solar array. A critical surveillance site may also require AC backup input or generator charging.
Recommended Project Inquiry Information
To design the right solar power system for a security project, the customer should provide the following information:
Project location.
Application scenario.
Equipment list.
Power consumption of each device.
Working hours per day.
Required backup days.
Output voltage requirements.
Quantity of sites.
Installation method.
Whether grid backup or generator backup is available.
This information allows the supplier to calculate the battery capacity, solar panel size, controller rating, protection components and enclosure layout.
A reliable solar power system is a key part of remote security projects in the Middle East. For CCTV, PoE communication, wireless monitoring and remote surveillance sites, the system should not only provide enough energy, but also have clear wiring, proper protection and easy maintenance.
