Get a digital multimeter and test for voltage with.
Solar batteries work the night shift to make the most of your panels daytime production.
All this is happening with the gate system completely disconnected.
I guess that would mean either the controller is draining the batteries.
Is a solar panel clamped to a battery a drain on the battery at night time.
It also ensures that power does not go back towards the solar panels overnight which can drain the batteries.
The only things connected are the solar panels charge controller and batteries.
A second way solar panels can indirectly power your home at night is battery storage.
The blocking diode may have failed and you are powering the panel at night from the battery.
The panels are draining them over night because the controller doesn t have a blocking diode or the batteries have had it.

Even a basic 40 amp converter will provide more charging than five 100 watt solar panels and it will do it night and day rain or shine.
Solar panels fill your battery with energy from the sun.
I suspect the charge controller is somehow letting the solar panel discharge the battery to zero over night as there is no other device in the circuit that can use that much energy overnight.
This question is in regards to a 100 watt solar panel that is less than a year old.
The solar panel is putting out over 13 volts in the sun.
I m new to.
The battery bank is a highly utilized and successful method to provide power at night especially during extended blackouts if necessary.
Only the solar panel is connected.
Now when i hook the solar panel up to my batteries the solar panel starts drawing energy from the battery.
In either case the company which installs your solar panels should analyze your situation and provide you with the best solutions to optimize solar energy use so that you can save money be prepared for.
