For you guys running residential fridges, how many amps do they pull while running? Trying to figure out my battery storage requirements.

Mine seems to be in the neighborhood of 12-15 amps.

Hi all. Great info here. I'm wanting to do a similar project (for general power purposes, not a res fridge) on our 30A 23BHE. Can you guys advise what alterations I'd need to make (e.g., mine has no ATS) from am equipment perspective? I'm assuming my shore power runs directly to the 30A breaker on the power center (will be replacing the WFCO-8735 with a PD4045-KV)? Planning on no solar right now. Just 2 Lion Energy UT 1300s, a Victron 712 monitor and a Multiplus 3k. Thoughts? I can place in a new post if that would be helpful. Or PM me. Thanks!
