How do you turn this thing on?
- Oct 12, 2021
BackgoundI purchased a new Airstream that came with:
- 2 lead acid batteries
- WFCO WF-8955LiS-J-WAGO charger / power distribution panel that is compatible with lithium batteries
- Progressive Dynamics PD1610J 1,000w inverter
Currently when not using our trailer we plug it in to shore power. If we're not going to use the trailer for weeks I would trigger the storage charging profile and trigger the 90% SOC profile a couple days before we leave for a trip.
I am using a Victron BMV now to gather data Ah usage on right sizing the battery I will eventually make. I plan on staying in the Victron family with a Victron solar charger down the road and possibly for my question below. Also to note, I don't plan on using an inverter my RV came with hardly if ever with the way we boondock. Everything we use on the trailer is 12v, appliances, lights, charging phones, etc.
My QuestionTwo ideas I had to get two custom charging profiles. I'm not what the best solution here is and would appreciate feedback:
- Put a Victron DC-to-DC in between the WFCO and the battery to get custom charging profiles. What I'm not sure on is if the Victron will allow electricity to flow in reverse to the WFCO distribution panel and to 12v appliances when the trailer is not plugged in to shore power.
- Replace the converter / charger in the WFCO with a Victron charger? I'm trying to figure out if Victron would have a compatible drop in replacement that would work with a distribution panel but I'm not sure. Could it power the power 12v appliances in addition charging the battery when were plugged into shore power? Maybe the Blue Smart IP22 charger or the Phoenix Smart IP43 Charger?
