Why is it my new mppt 100/50 solar charger register a yield of 120w at after midnight and calling is yesterday and yesterday's charge is now registering as 2 days ago? I'm confused perhaps a solar shower last Night?

Trying to understand the MPPT bluesolar Charging behaviour
Hi Ace. It's likely you've disconnected your panels at some stage, and the mppt will read that as a 'night'.
It has no absolute internal clock, and so it's days become 'solar days' of uninterrupted light.
Call this a 'glitch' or whatever, but it's more a remnant of the bluetooth developments to kit never designed to tell you the time. I guess it could be done, but would only add to costs.
And of course it's always possible to step up to a GX box and VRM portal for the limousine treatment.
Hi Southace, a few issues in the 30 day history report were fixed in the last firmware update.
To install it, a few options:
- wait a few weeks for VictronConnect 5.9 to be released (this is what I recommend!). It will install it automatically. Or:
- download the VictronConnect 5.9 beta https://www.victronenergy.com/live/victronconnect:beta, or:
- use the VictronConnect you already have and take the firmware file from https://professional.victronenergy.com. That also has the change log. Or
- use VRM Remote firmware updates; requires a GX device to be in the system.
So why would my solar controller make power at 3am in pitch black darkness? Or is it just a glitch in the system?
So that's my first week with the blue solar 100/50 and my second day with the VE direct blue tooth, still puzzled why it did a little charge after midnight, I did see a news report about a solar sky show around midweek I doubt that would be the cause though.
Today has been my lowest yield for the week yet the charge went to absorption in the quickest time (11am) I Would have thought it would be better to keep it at bulk for at least 6 hours like most 3 stage chargers?
Both screenshots show pm as time at the top. Makes it midday to afternoon which sounds very reasonable with the sun up and what not.
Another interesting day of charge can now see a patten where I isolated 600amph battery bank and now just charging the 400amph bank.
I wonder how the next update will change this. I can see the absorption time varies a bit.
Thanks to whoever re formed my post liisting.thats a first!
Today's been a good run I added the 680 amp bank last night and the system went to float after lunch my min volts are looking good with a fridge run overnight. 12.6 mins and 14.4 max is what I'm happy with for 1000 amphr agm battery bank and 500watt of solar.
