I went to the Danger Zone.. I have mounted 6 SunPower SPR X21-335 PVs on 2007Coachman Mirada.
I am ordering a pair of BigBattery 24V 170ah LiFePO4 Power Blocks, for 48V config. Yes.. going BIG.
This Class A RV is a 50a config. There are no 240 appliances... the dist panel divides the loads on for
each of the 120s. I will not be adding or changing any electrical wiring. I will install the inverter, chg ctlr in
RV's external power bay where an existing 50a receptacle from an onboard 5500w Onan and the RV's
50a service cable is for plugging into shore power (or the Onan receptacle). No transfer management exists
or is wanted. I will simply plug the RV's 50a service cable into shore pedastal, Onan receptacle or new inverter.
The main driver for this approach is easy install, easy removal, easy use, all without wiring work to RV.
Notably, the 48v batt array will sit on the RV floor above the external power bay for short, easy connection.
I am getting vertigo from comparing wired power centers, reputable 4400w and above inverter/chargers,
ample charge controllers for connecting PVs 2s3p. Taking a timeout and tossing out for responses, comments.
Thank you in advance for gawks, coughs, laughs, but especially useful feedback or ideas. Rick
