Solar and backup power for CCTV
How to size backup power so cameras keep recording.
Add up the load
IP cameras typically draw 4–10 W each; an NVR 15–40 W. Add the router and switch if you want remote viewing.
Battery and solar
Multiply load by hours of backup, then allow for battery depth of discharge and inverter losses.
