Hey Laurentius, thanks for the information! Your WFCO WF-9990 has a 90 amp converter in it so the only option we have to match that rating is the Progressive Dynamics 4500 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel - 90 Amp item # PD4590K18LS8. We do not have just a converter section.
What kind of RV do you have?

Question: Looking to upgrade batteries in RV from Lead Acid to Lithium Ion. As I understand the converter will need to put out 14.5 - 14.6 volts which the WF-9990 does not do. What converter is recommended as a replacement? Cheers Roy
