Solar and Remote Site Troubleshooting Hub
Troubleshooting hub for solar CCTV, 4G routers, remote sheds, battery backup and off-grid power issues. Use this page as a starting point before moving to a specific wiring diagram.
Safety note: Troubleshooting should be done within your competence. Isolate power where required and follow the manufacturer instructions for the actual equipment.
General troubleshooting workflow
Confirm the symptom
Reproduce the fault and identify whether it affects one device, one circuit, one cabinet or the whole system.
Check power first
Verify mains, power supply, PoE, battery, fuse and polarity before changing programming.
Check cabling and terminations
Inspect labels, patching, pinout, continuity, distance and environmental damage.
Check configuration
Confirm addressing, zones, relay mapping, VLANs, recording schedules or user permissions.
Document the fix
Update the as-built notes so the same fault can be diagnosed faster in future.
Common problems
- Camera drops out overnight: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- Battery not charging: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- 4G signal weak or unstable: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- Solar controller fault: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- PoE switch reboots: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- Remote app access intermittent: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- Water ingress in field cabinet: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
- Voltage drop under load: start with power, cable continuity, device status, programming and the relevant diagram before replacing hardware.
Quick checks before replacing parts
Physical checks
- Cable seated and labelled correctly
- Correct voltage or PoE class available
- No water ingress, crushed cable or loose terminal
- Correct polarity where DC or bus wiring is used
Configuration checks
- Correct device address, IP or zone number
- Correct relay, lock, siren or output assignment
- Correct user permission or schedule
- Correct gateway, DNS or cloud/app registration where relevant
