Charger converter upgrade questions ?????

Consider T125s (same physical size) and T145s (taller) too.

Chargers should be around 10% to 20% of the capacity of the battery bank.
And to get full advantage of upgrade put it as close to the battery with proper wire size.
The iota 55 amp and under needs a 15 breaker, shiuld be same. Just leave existing converter where it is unpowered.
That what I did, I have the Iota 55 for 430a/h battery bank. And I made it so it can be plugged directly to my honda 2000w.
Have a nice day.

Best converter.com Progressive Dynamics upgrade. Take your choice, spend your money. be happy.

Agree with Sidecar. I changed my Magnetek 6332 **** for a PD4635 and am happy. I got it from Best Converter. Randy is their expert. Here's a thread I posed similar questions before the purchase:

My posts start on page 3. I think you will find it helpful.

Here is PD's page:

I installed an IOTA-55 stand-alone deck-mount converter in my pass-through. It's a short run to the 2 G29 batteries and I have the original WFCO converter disconnected but still use it as the main DC distribution panel.
If you keep the current converter but disconnect the charging section you don't need to change any fuses.

When I upgraded my Magnatek to Progressive Dynamic 45 amp I also upgraded the wiring from the converter to the batteries - that was primarily to facilitate faster charging not a safety concern.

Our thread from earlier this year where many good folks weighed in to help us choose a new converter, as well as batteries, inverter, ATS, etc.

Some good info in there. Maybe something you find helpful ;)

Do you expect a fast charge on generator power? If so you probably need to pull wire to reduce resistance. I recommend #4 marine grade wire.

No generator? the 30 amp IOTA or 35 amp PD will work just fine plugged in. Actually even with a generator these would charge like a rocket compared to the existing Magnetek.

I am in the slow process of converting my trailer to the marine way of doing things.

Out went the cheap & nasty converter/charger. In went a not cheap 2000W PURE sine wave inverter/charger. Out went the wet cell 12V batterys. In went a single 4D AGM battery which after 8 years is still going strong & needs absolutely no maintenance.

At some point the 12V fuse panel will get replaced with a 12V circuit breaker panel.
