IMO,
with either generator, the WFCO will likely be your bottleneck
IF you let the batteries become moderately to seriously discharged. My WFCO, and others on this forum, doesn't stay in 'bulk' mode long enough and then switches to 'float' mode. Float mode has lower current and voltage and takes longer to charge your batteries.
Suggestion: For lower draw from your batteries, start with your batteries fully charged and run the generator to charge your batteries
while the greatest use of 12v power is occurring. We did that last summer by
running our generator at low speed for 2hr in the morning and 2hr at night when our 12v use was at its maximum. We are very stingy users of 12v - no television or other electronics and used our LED lighting only as needed.
Our mistake (mine, actually
) was not starting to use our generator immediately! We waited about 3 or 4 days. Then our 2 batteries were discharged to about 75% (12.4v) before we started using the generator. After that, even running the generator about 8 hours one day (against the park rules, but, hey, no one else was in the CG and we were the CG hosts
) I could not get the batteries back to fully charged. That blew our plans to run the generator once every few days! We had to run it every day, twice a day to keep from ruining our batteries.
There's more to the story, but the above is probably TMI anyway.
Linear Mode
