Greetings! I am the proud new owner of a AC200P.
I (unfortunately) already purchased a Rockpals 100W (90W = 18V*5amp) RP2 foldable prior to getting my Bluetti AC200P.
Question #1: Is there a world where I can make good use of this panel? (Ideas welcome!)
(I’ve been scribbling down various scenarios, but I keep coming back to the best option would be to relegate the Rockpals to ad-hoc charging of my lead acid batteries (with the addition of a cheap charge controller that supports both flooded and AGM) in my car and/or trailer. i.e. Just cut it out of the “main” system because the low amps pulls the whole output down.)
Question #2: (My Main Question): If you had a budget of ~$400 or less (preferably less), an existing 18V/5A foldable, and an AC200P, what would you invest in solar-wise for camping in the Pacific NW?
Option #1: Jump ship for two higher amp (and watt) panels
i.e. The purchase 2 BougeRV 180 watt panels for $332 for a net voltage of 36V (Just over the 35V min) and ideal voltage of 360 watts. Total weight of around 48 lbs (24 lbs each) I think.
Folks that have the larger 180Watt solid panels for camping - do you find them unwieldy? (DIY Solar suitcase / packing ideas welcome!)
Option #2: Double down on the same foldables for a series of 3 total?
In this option, I’m spending another $370 for 2 of the same Rockpals for a net voltage of 54V and 270-300W. Upside: That gets me a weight of 28.5 lbs (9.5 each) and portability for certain. They’re nice in that way, but I’m wondering if I will miss that 60-90 watts and that $38? The other big MISS on the part of past-me was that the Rockpals (being a fabric foldable) are not fully-water-rain-proof, but I believe the BougeRV flat-style would be.
Use case: Boondocking with a simple 17’ Casita travel trailer. (Fiberglass egg.) Loads include (propane) furnace fan in chilly NW months, water pump, stove fan / maxx fan when cooking, led lights, various AC/USB electronics with their own batteries. (e.g. ipad probably the biggest) Fridge is the ultra-inefficient (DC-wise) absorption style, so that will stay on propane. Can easily do a long weekend on the existing ~88ah flooded interstate battery, but we would like to do as much as 2 weeks off grid.
FWIW, I do not plan on mounting on the camper because I figure I’ll need to chase the sun around the campsites. (State/Federal/Dispersed Camping.) So… The BougeRV would probably get legs hacked on somehow.
Many thanks in advance for your time and opinions!
Best wishes to all!
