Thanks for your help.
I don't use voltage as an indicator. I just mentioned it as a point of interest in this situation. As a side note .... I have a Go Power Solar Charger and a Magnum Battery Monitor Kit panel. 4 x AGM 300a 6v set up as 2 x 300a 12v. So, 600a 12v system. The alarm is sounding on the Go Power Solar Charger.
In order to test the night time situation, I tried to simulate night by turning the breaker off on the solar panels (The breaker site just next to the PV wires as they enter the camper from the roof). When I did this I got the nighttime icon, and zero amps of charge registering as you would expect. The problem (beeping and POL code) went away.
So the issue is happening only when the breaker for the panels is on and it is actually dark, with no charge registering. Turn off the solar panel breaker (night or day) and the issue ceases.
The issue also doies not occur with lower power appliances. Charging my laptop for example, although we don't have anything in between a higher wattage kettle and low wattage charge to test that middle gound.
I realise that the open circuit is not the same conditions but a worthwhile exercise in dialing things down maybe.
Still think the alarm might be a lower battery state issue? We have not plugged into shore power for a while so likely have not hit a proper full charge.
