Auto gen start settings Journey 2013 36m

I have a 2013 36 M with auto gen start. The unit has a house fridge with
A 2800 wat inverter and 6 AGM batteries. My question is what low voltage
Should be set and what stop voltage should be set. Also what type of
AGM battery setting should be used AGM 1 or type 2 on the inverter charger.
Called Winnebago and they had no clue at least the guy on the phone did not
Know and sent me to Cummings who only had a guess and did not know
What Forrest City sets them at ?

I haven't checked Autostart yet, by my inverter is set for 400 amp hrs, and AGM type 2.

The way it came from factory.

I had Paul Smith of 3TTTs check it out shortly after we got the coach and he said all inverter settings were correct.

Cummins, not Cummings

I haven't got that far in the owners Manual yet. I need answers too.

I have mine set to start at 12.1 volts and stop at 14.4 volts after 1 minute. You can go lower with the start voltage if you wish but the higher you keep it, the longer the battery should last. AGMs cannot take as deep cycling as flooded batteries so the voltage should be higher when the genset starts.

Thanks for that Bob ! I agree on the low volts at 12.1 . my coach has the AGM type 2 batteries and am not sure at what volts I need to have set for the generator to shut off.

I assume you have the Magnum inverter with the OEM control panel supplied by Winnebago. I suggest you google Magnum Inverter and download the manual for the full remote control. It has considerable detail on setting up the inverter and the voltage levels used with their AGM2 setting along with the battery manufacturers it applies to.
You want to d/l the "Magnum ME-RC Remote Manual". On page 20, you will find the settings - AGM2 provides an absorption voltage of 14.5volts. That is the voltage that the charger portion of the inverter will provide to the battery when it is being charged. I would use 14.4v as the shutoff on the AGS after the battery has held that voltage for one or two minutes. If you use the 14.5, the charger might go into bulk mode and reduce the voltage applied before the AGS decides to shut the generator off. If you were to use a significantly lower voltage, the battery would not achieve the proper level of charge. Once a three stage charger has achieved the target voltage level, it switches to the float level which is one volt lower. You really want you AGS setting to align with the charger setting for best results.

I just took a look at the online manual and that has a lot of good information, I'm not saying I understand it all but it is a place to start. Thanks for posting, Jim
