You need to become a lot more familiar with your system. Off grid is not a set and forgot. That being said, you have two methods of charge. One being the charger in the inverter, the other the solar panels through the charge controller.
Both have settings that can be configured to the battery type you are using. Set some of them wrong and you will ruin your batteries and could cause a fire. So some of those settings are password protected. Some of the settings need to be fine tuned and adjusted seasonally. If you use any power from sundown to sunup the solar charge controller should start in bulk every sunrise. Once charge amps taper to a set point that is internally determined by the amp hour of the battery that has been entered into the solar charge controller (SCC). Then it transitions to Absorb which is a time based setting. Lead acid needs lot’s of absorb time. Then at the end of time the SCC goes to Float. Should stay in float the rest of the time the sun is up. If it clouds up in the middle of the day then clears off before sundown it starts over from the beginning with Bulk, Absorb,Float. This is specific for Schneider SCC. I believe that is what you have seeing the buttons in the pictures.
The charger inside the inverter that is powered by the Generator has the same settings. Most people use the generator to Bulk charge (put a lot of amps into the battery in a hurry) which is about 80% of total charge. Those settings need to be Set to match your battery requirements. These I think can only be adjusted in the SCP. Do you have one? It is a interface between all of the Schneider components. It can be mounted alone of in place of the inverter screen that has lights to designate state of charge. I am a thousand miles from my system. When I get back next week I’ll look to see, I think the DC Over volts, and Under volts is user settable. In the SCP you can look at the fault history. You should be able to see what the voltage was. Batteries. Look neglected. Have you unwired and cleaned the connections in the last six months? The more you know about your system you can better communicate what you have and what is going on. I have to assume you don’t have grid power and this is a hobby. Your post is a little like “ I have a car that has been running good but, now it quit. Can someone tell me what is wrong?” We are all happy to try but my just cause more confusion.
