First, I want to say I will not attempt any modifications until I get an approval from Eberspacher.
I have a airtronics B4L M2 installed in my Transit. I went with a Ecoflow Delta Max to supply power to it and few other items. What I am finding is at the start up stage of the Espar, the watts for the fuel pump and fan will fluctuate from 50-148 watts. The EF Max 12 volt cigarette output allows for 126 watts. On first attempts it will overload the 12 volt but if I kick everything back on shortly after it will do its 30 minute cycle. Likely because the initial heavy load is over and now the watts drop below 100. My question is, if allowable and approved, is there a way to limit the fuel pump amp draw just a little so the cycle does not overload the EF 12 volt circuit? I obviously do not want to mess with the fuel pump functioning properly but if I could get the amps decreased by about 2 I think it could work. I cannot tell if a DROK Buck module is an appropriate device or something else inline that serves this purpose. I know I can fabricate an AC to DC converter to my fuse panel and everything would work but I would prefer simply not doing that inefficient process if it can be solved easily. Thanks for any input.
