Replacement Converter PD9270v

The PowerMax 75amper has PF correction, so it will run on the 2000w gen ok with room to spare. However, the PD has a Charge Wizard feature, which can be a handy thing at times.

Assuming the PD 60 really acts more like a 55, as many have reported, there is still not that much gen time to be saved going from a 55 to a 75 doing a 50-90.

On balance, much as I like my PowerMax, the OP's choice of a PD 60 amper is sound, IMO.

Do you think that the PD would be a good replacement for the WF converter??

YES!

I think that would be a very good choice.

You can get away with higher than 60 amps on an eu2000i if you're willing to make sure the battery doesn't get highly discharged, cut other loads when necessary, and/or manually kick the converter out of boost mode when necessary. If you really need the bigger converter, a power factor corrected model might be justified.

Thanks . . . . good info. I am not sure, but I think that you are saying to get the 70-75 amp converter.
How do I manually kick out the boost mode on a converter? Is that a special option on some converters?
We don't boondog much, but I have a Harbor Freight 3000 generator, and I plan on doing some boondogging where I will need to use the generator.

I went through Bend 40 years ago, and fell in love with it. I remember one gas station and one diner. A guy at the diner said he shot a buck off of his porch. I returned to Bend 15 years later, and decided to look elsewhere.

The PD "Progressive Dynamics" product line is the only moderate cost converter that provides this ability. In my and many's opinion one of the best features avail for charging our batteries.

Sometimes when one starts charging and the batteries are cold they will cause all converters to not go into Boost/bulk mode. Thus charging will be slow. If one has the PD with the controller he can switch modes to bulk by pushing a button.

Another is if you have a big battery bank and a high amp converter 60+ and are trying to charge using a smaller genny you can switch modes to a lower charge rate, ABSORB or Float until the batteries have charged enough to allow the higher charge rate of bulk mode.

Another is when your batteries are hot 95deg+, because of hot weather . You do not want to charge very long in bulk mode with any converter. The PD allows you to switch modes to a lower setting and thus not boil your batteries.

Thanks all for you recommendations and ideas. I will get the 65 amp PD.

whatever....I have watched my Iota 75 put 73 amps into the 50% battery bank while being powered by my Honda eu2000i.

Renoman's experience is the perfect example of why I stopped guaranteeing and promising. Sometimes things just work out differently.

The PD units are IMHO a definite improvement over the WFCO units. WFCO are not known for going into bulk mode charging for most users.

If you dry camp and use a 2000W or smaller generator, I'd recomend the PD60A unit over a bigger one. The reason is that the 60A is already near the max continous rated VA for many 2000W generators. The actual current draw is near 1500VA (much higher than the watts, related to the poor power factor) when charging well discharged batteries. The 70A unit may push you over the edge with a 2000W generator, especially at higher temps and high altitude.

If your not "generator" limited, go for whatever will fit.

My Honda 2000i runs my 75 amp Iota just fine.

I have had problems with single stage power converters shortening my battery life in 2 different rigs. In both cases I replaced what I had with a multi stage Progressive Dynamics charger and my batteries last much longer.

It looks like you model has a built in "Charge Wizard" - I'd keep it. Looks like a great piece of equipment.

That is the model you are talking about, right?
