Re: Converter voltage drop
OP here...thanks all for the input. A took a closer look and my converter to battery run is closer to 15' one way, with mfg installed 6g wire. So a re-wire seems appropriate. So I've decided to keep the WFCO and use as a converter only when on-grid. It works fine in that capacity. Then buying a Mean Well NPB-750 charger to use with the generator off-grid. I can place about 3' from Batteries (which are 2 Weize 100ah). I think a better solution than replacing the converter/charger with a better one (was leaning toward the PD 9200 series). And I would still want to upgrade wiring if going the replacement route. I have left over 2/0 wire from the battery install that I can use with the Mean Well. Still open to suggestions if I'm still wandering around left field on this.795Views0likes0CommentsRe: Converter voltage drop

Personally, I would just eliminate the converter and buy an inverter/charger/automatic transfer switch. New to this so hopefully replying in proper format...all LFE specific converter/chargers I've found have a 14.6V bulk phase. My battery mfg says to stay at 14.4 or less in bulk. Are there LFE chargers that start at 14.4? Regarding an inverter/charger, I already have a 2200W pure sine wave inverter that Works great. My best value seems to be using existing inverter and upgrading the converter.449Views0likes0CommentsRe: Converter voltage drop
Thanks all. I did try the WFCO and it supplied 14.4v for a few minutes before going to 13.6v. Not a good option to quick charge with a generator. Regarding the PD 9200 series (non lithium)...I can use the charge wizard to bulk at 14.4v and hold it there for 4 hours. If before that 4 hour period is up and the battery is ready to absorption, will the PD move off the bulk phase? For most part, will be zapping battery with generator for a few hours at most. So will still be in the bulk phase. But If I want to fully charge, will the PD9200 do that if I use the charge wizard set to bulk at 14.4 and absorption at 13.6, or will I have issue as the WFCO and bulk cuts out after a few minutes?451Views0likes0CommentsConverter voltage drop
Just replaced lead acid with LFE (200ah) and want to change converter to a lithium specific unit. Current unit WFCO WF-9855. My LFE's suggest a 14.4v bulk charge. Converter's I'm considering all bulk at 14.6v. Do I take voltage drop into account when determining bulk charge at the battery? And will a 14.6v at converter work in my situation? I have 6g on an approx. 10' one way run between battery and converter. New converter will be a 45A model. A 1.5% drop will bring 14.6v down to 14.4v. Based on my limited knowledge, I'm thinking I'll have at least a 1.5% drop. Also note that I'm planning on getting a 45A unit to replace the WFCO 35A. Am I correct that current wiring will handle that? Thanks in advance for your input.6.2KViews0likes30Comments
