Help with choosing proper converter amperage
I'm finally replacing my failing converter and am looking at the INTELI-POWER 9200 SERIES CONVERTER/CHARGER - 60 AMPS. My question is, my trailer currently has the WFCO 55 amp (yeah, yeah WFCO.....I ...

Difference between 55 and 60 is 5 amps which in slightly rounded terms is "Less than Ten Percent" In Electronics we more or less ignore "Less than 10 Percent" and consider them to be the same (There are exceptions but this is not one of them)
In short consider the 60 amp PDI to be identical to the 55 amp WFCO in all respects save quality and charge alogarithm (Much better on both) .
How to compute proper size of converter if DESIGNING an RV. (note: once someone else builds it wire sizes come into play,, So use above guide for replacements).
Add up battery 20 hour amp hour ratings (C/20 rating)
Group 24. about 70-75 (73) amp hour
Group 27 just shy of 100 (say 95
Group 29, Just over (Say 105
Group 31 130
GC-2 Pairs 210-230 depending on sub-model (note this is the capacity for the pair, also for each battery but in series you add bolts, not capacity).
Add up your battery bank.. Multiply by 0.30 (30%) and that is your ideal converter size. For a 220 AH GC2 that would be 66 Amps, So you'd use a xx60 converter.
