Charging my alarm backup battery using solar
Anyone DIY a solar charger for your alarm battery? I’m looking for guidance to set mine up. Is is as simple as connecting a panel to a regulator to the existing battery? What about the built in charging from the alarm system? Should I rather put it a bigger battery while I’m about it?

I can't advise on the solar, but regarding the battery, it's easiest to run two batteries in parallel to double your capacity.

Our electric fence system [Nemtek] uses a double size 12 volt battery which gives us x2 times the back up when Eskom plays its load shedding games.

I am also interested in this. I want to connect a 100 aH battery to my alarm system.
I have 32 zones and 20 of them are beams outside. This drains two 7ah battery in 4 hours.
I would also prefer to charge battery via solar.
Our power was off for 2-3 days in a row twice now so need a plan soon.
I want to upgrade battery and charger on gate motor also as you can open/close the gate 6 times and then 7ah battery is flat when power goes out.
On the alarm system I have tried a tiny relay connected to the leads that go to the 7ah battery to the coil of relay and as soon as the charger looses charge the relay feeds power from a bigger battery back to those two same leads of the charger but on my alarm the brief switch over of relay switches my alarm off totally. Probably some sort of protection of the alarm when 7ah battery gets to low or something. I need to have a small battery connected to the alarm at all times to solve alarm going off because of low battery.
I want to try this setup on the gate motor as well but first need to install a secure box to leave a bigger battery and solar panel and regulator somehow without the midnight wanderers getting their hands on these items for their own personal use back at home.

As I am also looking for answer to this challenge I contacted my service providers technician and he suggested a USB.
What do you guys here think?
