So I’ve been running generator for 4 hours now and it’s still MPPT bulking. Outback says 59.0 volts. Do I just keep going until it starts to absorb?
Could my outback controller be failing somehow?
For some reason my inverter keeps kicking off the generator. Not sure if I need it at this point. However it’s not sunny out and the outback controller just went into snooze mode. What’s happening.?
Yeah, you haven't reached absorb yet, the battery isn't full so the voltage isn't 'running away'. Setting to Equalize isn't helping really, because the battery is limiting the voltage. Taking 2% is pretty ugly, it might be time to get Rolls involved ask them what they would suggest. I understand high voltage pulsed current is sometimes used to recover. I suspect, your battery is heavily sulfated, so the sulfates are covering the plates not allowing the passing of current. Equalizing helps in 2 ways, 1 is to return sulfates into solution, and the other is to simply aggressively get them to fall off (I've even heard of people bumping and banging their batteries!) Once they fall off they expose more area of the plate...Equalizing, it's self, generally is done on a fully charged battery, hence no real reason, in a properly designed system, to remove loads.By raising the voltage you are 'tipping the scale' allowing/forcing the battery to take more current. It's a controlled over charging of the battery bank.If you are having a sunny day, you might compare the flow of amps to the battery bank from the array and from the generator. It could save you a lot of gas and food.

The combox screen in post #50 is exactly what you would see if the genset is not qualified or off/disconnected. The phantom 439 watts is from the solar. Even though it is not networked to a schneider mppt, there is a Hall sensor that shows 439 watts. It is coming in from somewhere, like the FM 60. Genset is where Schneider shows unknown power to not confuse people if there were a Schneider mppt and its Hall sensors in the network.
Vic said:If one had a FLA bank that really needs a good Absorb, and EQ (sulfated plates), the battery would Accept a lot of current. Have probably not dealt with too many battery banks that had Hard Sulfates, but just my experience is if the charge source can deliver a lot of current, and is able to reach the necessary voltage setpoint, as the charging process progresses, the battery will Accept a lot of current. This bank is either not Accepting, or the charger is limiting the current.I do not know the workings of the CSW's charger. Perhaps it is still trying to Absorb. Dave did mention, that with Schneider inverters, when the EQ is initiated, that a new, full Absorb needs to be done, even if one had just been completed. (this makes little sense to me for off-grid systems, to me ... Schneider!).The OB CC thinks that IT is in EQ, but, the CSW may not be. Could not find the CSW charge state on the Combox image.
