Our van has been sitting round for approx a mth in storage
It hasn't been connected to 240v , I have checked it a couple of times, and the V read 13.5 or around that from memory.Cant remember if the sun was shining at the time.
It obviously is Charging from the SP .
Theres no load on in the van , yet it has drop down and it reads low battery tonite.
I know that when the voltage gets down to around 11v the solar charging stops .
Is it usual for the batteries to drop V when sitting idle .
The weather has been very cold and gloomy here in vic over the last few weeks .
Should I be connecting to power during the cold grey weather.
The answer is yes, lead acid batteries will discharge when idle, and even when not connected, as they get older, they discharge quicker, don't ask me why.

Where did you get that gem from? If your battery voltage gets down around 11 V then when the sun shines the system should go into full charging. If it is stopping there is some problem in your system.

I was told that by the sparky that wires up all the vans for the manufacturer , I think its the regulator that stops any charge from the solar panels once they hit 11 v or below
There are some 240 V battery chargers that will not start up unless they see at least 8 V from the battery. There are also some chargers that need a good supply from a 12 or 24 V battery to set up their operation (ie whether to operate as a 12 or 24 V charger) but once set up they are then OK as long as they are not disconnected from the battery.

On the bus I have an mppt regulator and on the Patrol I have a standard type regulator. When the sun shines both of them charge whether batteries are charged or flat. Charge on and charge off can be set on the regulators but it has nothing to do with the battery voltage.
I'm not talking about the charger in this instance , but the regulator .?
The regulator is a charger. The regulation of the output is the same as the DC-DC and 240 V chargers. You still have not revealed what the make and model of your equipment is.
