Can anyone explain what this all means?

[Phill D]

Well we don't have MiFi, and chargers are taken out, we make sure everything (fridge, telly) is off when we leave the van.

I can't disagree but the data shows the battery needed more from the solar panel than it does now.
So I cannot explain that other than there was a drain on the battery from something that the solar was supporting.
And its not there now.

Well that's a bit worrying, I can't for the life of me think what it could be, maybe it was supporting something important!!

I have contacted the installers and the hab guy now. Thanks for all your help.

It could be that during the hab service they switched something off....

 

[Guigsy]

Invertor? Tracker? Alarm? Cab battery trickle charger? Cab radio switch was on the hab battery? Oven or locker light was left on?

Nothing is wrong, your battery is fully charged going by the voltage shown in columns G and H, so the system is only taking the solar it needs to keep the battery topped up.

I understand that, but isn't it strange that in a whole year its never gone that low before?

It is strange but can really only be explained by something was drawing power all that time.
I would wait untill darker this evthen switch loads on for a hour or so.
Then have another look at the readings tomorrow.
I would guess that they would be similar to what you have seen previously.

Is there any need for that? I am very upset right now.

Apologies no offense intended..

We are going out for the day tomorrow, so will see how it goes, I would also like to hear from hab guy and solar installers!

You need the lad on for a while while there is no sun for best results.

As said nothing wrong with those figure your min voltages all show fully charged batteries those figures would be at night when theres no solar input the max voltages are your solar putting a top up in during the day, think of your batteries as buckets of water with a tap dripping in to fill if you take water out of the buckets the tap will refill them if you dont take anything out the tap cant add any
By the way i thought your response to jamesh was at best curt, this is a fun forum and thread drift and witty comments are part and parcel of it

When battery’s are full solar doesn’t try to charge, well it tries, sees them full and stops. Your battery’s are full

Thats why the charger is now spending all its time on float the battery is fully charged. Try discharging the battery on purpose I bet the time on bulk increases until it's fully charged again.

I think that the hab check probably involved switching things on to check that they are all working, maybe for some time. The displayed amount of power is simply the solar refilling the battery again. However it does look as if there is a slight drain from the battery that is replenished by the solar every day. Possibly something still switched on or connected, like a control panel left on, or a USB charger left connected, a light on in a locker maybe.

Even with everything switched off, my motorhome will flatten its battery in about 2 weeks. There's a lot of parasitic devices in many motorhomes.
