A little thread necro here but I am as confused as OP and my confusion comes straight from late Amy Beaudet - The Solar Queen.
In her article on diodes she states:
So I assume this is what OP was referring to and @Hedges is offering in the previous post as a solution.
I am debating 3S vs 3P...
Had not seen the AliExpress All-in-one charger/controller.
I did look at the Renogy and ruled it out based on these review comments:
The problem with that second statement is that you might only get 30 amps of charge if the solar is producing a small amount of power (say 5 amps) and it truly...
:-)
Thanks. Obviously I had concerns so I was asking about anyone who actually bought one @Short_Shot.
I don't idle. 30A continous for many hours of driving would go a long way to keep my battery topped off. No illusion I am going to quickly recharge a depleted battery. And should have...
Anyone have any experience with one of these?

Sterling is way too expensive.
Renogy is better.
But I just wrestle with paying $230-250 for a device that really only exists to keep my soon-to-be lithium battery bank from sucking current too...
Hello panel peeps,
Home Depot is running a one day sale on Nature Power 215W mono 12v panels for $154 ($0.72 / watt)
Had been looking at Newpowa 210W mono 24v panels for $224 a piece and for Labor day they are dropping another $20 off (actually $60 off $500 order) so that puts them at $0.97 /...
The 210w panels in the second picture are 26.5 x 64.5" You can see that three of them side by side pretty much takes up the width of the roof. (about 81").
You can also see the brown spot where the old Zamp flex panel was on the roof. The flex panels are 45.5x21.5"
I got 2 90 watt Zamp rigids...
I just read @12VoltInstalls' comments about not angling 3S - I assume unless all three are angled similarly. So if I did pivot mounts it would be primarily for roof access purposes - though I am not sure how to do pivot mounts with pins where I could not reach the "far" end. Maybe a threaded...
These pics are not my MH - grabbed from a FB group.
Here is one with original flex panels moved from factory location plus a rigid:
And here is one that has the three 210 Newpowas I am thinking about.
Note this second solution provides no easy path to the front of the roof unless you walk...
Given the real estate, the 6 x 100 would occupy the same space as the 3 x 200/210. I have been thinking about a movable mount system that would allow all 3/6 panels to pivot to one orientation (or possible 1 or 2 ... or 2 or 4... to be oriented the same direction. TBH though - I think I would...
OK - I think I know what I am going to do.
3 x 210W 24V panels in series. Voc just shy of 40V so 120V. A couple of volt rise for colder than it will ever see at full irradiance. So maybe 132V max.
Epever Tracer4215BN. Max input voltage 150V. Rated max power 525. Overpaneling up to 1500W -...
@dpasch80 - I'll preface my remarks with "I'm a newb too" so perhaps blind leading the blind but I think I can offer some qualified perspectives.
The fuse is to protect the wire - not the inverter. You show 2AWG going from battery to inverter. 2AWG has a "chassis wiring" (open cabling -...
@circus Fit is the same. The 100w panels are pretty close to half the size of the 210w panels. Yes - I have thought about that.
@jberger - buck would only power the house 12V needs. No levelers. DC Fridge will run on 24V. Chassis battery/alternator stay the same at 12V. I haven't measured...
I may have made my first post too complicated so I'm going to post just one question.
I would like to put 600W+ on my RV roof.
Ive looked at HQST 100W compacts and Newpowa 210W (12 or 24V) panels.
Is there any advantage/disadvantage to 3 vs 6 panels? Right now - they are both basically...
Hello all,
The P.O.S. Zamp/Sunpower flex panels on my motorhome (2018 Winnebago View 24V) died. I'm getting a sub-optimum warranty replacement from ZAMP of two 90w rigids.
So - I am going to take the opportunity to just upgrade.
Current system:
1) ZAMP 30A controller
2) Progressive 30A...
