The house has an island solar cell generation system of 100 Watt peak to maintain the backup bateries of the burglar alarm and automation systems charged during extended blackout. Blackouts are unusual but, in the past, we had several regional and national blackouts for periods longer than 12 hours, and they can shorten the life time of the batteries and increase the down time of the system. In our implementation, the automation and alarm systems are powered by a solar cell panel and we use the factory power supplies as backup when needed. The charge condition of the batteries are constantly monitored by solar charge controllers to guarantee operation of the SCS bus during long black out times and periods of poor sunlight.
Solar_100 Wp
The Solar DC system enables the reboot of all network and computer equipment, remotely, using the alarm central and the GSM wireless access.
Solar Kit
The Solar Kit consists of a 100 Wp, 12 VDC Solar Cell Panel with two Battery Chargers to assists the charging of Battery 1 of the Burglar Alarm System, and Battery 2 of the Automation System. The charging of each battery is constantly regulated by each Battery Charger during long black outs and sunlight times. Load 1 and Load 2 serve to indicate the charge condition of the batteries. The load is disconnected when a battery voltage goes below 10.5 DC.
Solar Chargers
The pictures describe an implementation to power automation and burglar alarm systems using solar cells, the power supplies are used as backup when needed. The charge condition of the batteries are constantly monitored by solar charge controllers to improve operation during long black out times and periods of poor sunlight.
Burglar Alarm System
The Burglar Alarm System is simultaneously powered by the:
- Public Utility, and
- Solar Battery Charger (in the event of power blackouts)
The Central burglar alarms generates a call when there is a black out.
Automation System
The Home Automation System powered by three energy sources:
- Solar Cell Panels
- DC Battery
(Charged by Solar Charger on sunny days, and AC Charger when needed) - Public Utility
(Controlled by Battery and Sun conditions)
