[RE-wrenches] Off Grid Alarm Communicator

[Carl Adams]

Hello Wrenches,

I had a request from a local alarm company for a small PV - Battery
system to power an alarm communicator system.  The parameters given
are as follows

12 V DC power supply to the gear
standby load 28 mA - this is the majority of the time
Operation peak load 2A for 2 minutes - once per day for communications
check and as required for alarm condition report

Have any of you provided such a system and if so could you share your
recommendations for a cost effective solution.

With Regards
