I have registered here to try and get some advice with a solar powered sliding gate system. the gate is approx 160 meters from the house and there is no mains electric so hence the solar system.
The gate system is 24dcv and the battery pack is 20ah charged by a 24v 30w panel.Originally it had a 15w panel but i have gone up to the 30w in order to have a greater charge rate in case we have a cloudier spell of weather.
I am also wanting to fit a wireless video/intercom system that I am assured will work over the distance as there is line of sight from the gateway to the house with no obstructions. However this is a 12v system and draws 60ma at standby and 300ma when in use.
My questions( as a newby with solar) are;
1. Can I use the 15w 24v surplus panel (says it has an open voltage of 42v) to charge a separate 12v battery for the intercom system?
2. Would it be better to add the 15w panel to the 30w in parallel and power the 12v intercom from the present 24v battery ( with a transformer or some such)?
3. What charge controller,fuses,etc etc would I need if i use a separate battery for the intercom and what size 12v battery would I need?
Any kind advice would be most welcome
thank you
