Installing 3 Stage Converter/Charger on 2013 View

[LeeB]

Thanks John...... I can see both directions are the same no matter which inverter is installed... I suppose it will boil down to performance, like when anyone compares a Ford to a Chevy.....

I see John your in North Dakota..... Stay warm....

Hello LeeB,

I’m not too sure you need to worry about the statement ‘then will continue
“trickle” charging at a very low amperage rate’ if you leave the original batteries installed. What this means is that the batteries are under a ‘float’ condition. That’s good. Would a good AGM battery bank be better, you bet. If that is what you are going to install, then I would strongly suggest installing a 3 stage battery charger that has settings for AGM batteries. Normally, all batteries will self discharge. That is what is meant by “trickle” charging at a very low amperage rate. It’s just that AGM’s self discharge at a much lower rate. And usually need a higher charging voltage. The forth stage is equalization which isn’t every applied to AGM’s.

The advantage of a three stage, are increased amperage to restore full charge but the last stage is still float. It just takes a lot longer to top off the batteries when float is all you have.

VOLTAGE LIMITS
WITHOUT LOAD: 13.6 VDC MIN / 14.1 VDC MAS

WITH LOAD OF 55 AMPS DC: 12.9 VDC MIN / 13.1 VDC MAX

Just to check I send a note to my friend at Winnebago.
"According to our Electrical Engineer, it is only a single stag charger"

I like your choice of charger, I will probably do the same when we get our Adventurer this summer.

I'm sorry for falling off the cabbage truck, but this reply is confusing to me. Are you saying that Schumacher, the maker of the converter/charger that Winnebago now uses is really a there stage charger, but your frind at Winnebago is saying that it is a single stage charger? I know that the manual talks about the charging current chaging based on the battery's state of charge, but the Winnebago manual states in a couple places not to leave the coach plugged in.

DeWat, Sorry for the confusion, I have done a lot or research on this converter/charger and I was sure it was a single stage charger. So when the guy at Schumacher just gave me max and min voltages even though he stated it was 3 stages I had my doubts. So I emailed my contact at Winnebago an sure enough it's just a single stage charger and that's why Winnebago said not to leave the coach plugged in.

We left North Dakota two weeks ago. We are boondocking in the desert 20 miles north of Yuma on the Colorado river. Mid 70's today.

Good Timing......

Thanks much! I had a live conversation with Winnebago today. Because of the new chargers/converters, they are not going to go "on record" and give any official nods, but said that I should be okay as long as I monitored my batteries regularly. They also told me that when I turn the house switch off, the batteries do not charge, so if I really get concerned, just turning the house off is a lot easier than unplugging... especially since everything inside will still work direct from the shoreline.
