question

Fist port'o'call. Pull the pv wies from the mppt and confirm their polarity with a multimeter.

Do you have you a BMS for your lithium batteries communicating with your MPPT somehow?

If so the brief bulk led blink every few seconds can indicate 'not charging' & be caused by a remote request (from the BMS or any device with remote control) to stop charging.

Based on your screen images I cant see anything wrong, apart from the fact that it seems you don't have enough solar POWER available to bring the battery up to the absorption voltage (in consideration to your battery state of charge and loads).

Don't be fooled with the solar panel VOLTAGE ALONE. It is solar POWER that you are lacking.

The history graphs also support this - most days you never get out of bulk.

The battery voltage rises gradually from it's start voltage to the absorption voltage once it absorbs enough charge energy - this is not an instant thing, particularly with insufficient charge current (to cover both the recharge & any loads).

So I recommend to reduce your loads or add more solar power (or both).

If you want to test my advice run it for one complete good sunny day with all loads turned off/disconnected.

Your charging voltage will raise to the 14.4 at the tail end of the charging cycle. I have a bank of six and the charge voltage is pretty flat until right at the end.

@bolandd: The battery voltage is the reading of the battery. Lithium batteries are unique in that their voltage does not immediately rise to the voltage they are seeing. The voltage reading shown is what the battery would also have right after disconnecting the panels. A lead acid with 12.1 volts will read out at 14 when you connect a 14 v charger, then drop down to it's new voltage after shutting off the charger or panels. So the only problem is that you are thinking this reading is showing the charger output but with your Battle Born it is showing the actual battery voltage.

The number under "battery" section in the app that I like to watch is the Current entering the battery - although note that this is a net current and charging current will be offset by loads. Most important of all is the wattage reading of the panels. This is why it's the big meter. This is your best reference and tells you how much charging power you are getting. Helps for aiming the panels and to verify that you are not getting unexpected shading. Be aware however that if you ever get into absorbtion mode, the mppt will lower the power as well to match what is needed.

Victron makes great gear but as a former technical writer, I do feel they could do a better job explaining their products. The manuals and videos especially seem overly-simplified. I have figured things out through use, but may be wrong so hopefully someone from Victron can confirm or correct my explanation.
