So what'd you change in the setup after you replaced the EG4? Installing the same unit in the same setup wouldn't really give me confidence.
Can you run inline fuses on the +/- leads to the battery? Maybe MRBF style fuses?
Old thread, but tint all your windows, windshield included. Most of the heat input into car/vans will be through the windows, especially if you have the roof covered in panels already. A 70-80% VLT ceramic tint is almost invisible and will cut down on UV and IR ingress dramatically. Darker will...
Anyone probe these pins to find if it's just a regular SPST switch?
It's such a big panel for limited functionality, would rather just incorporate it into a larger multi-switch panel.
You wouldn't be the first to quote that number, and you won't be the last, but it's a PEAK number.
The real numbers are available if you dig past the the marketing smokescreen.

This is great data.
Any more details on the loads you are running? I was hoping to have similar performance in my setup, but have invested much less in panels (mostly due to space limitations). Either my expectations for load are way undersized, or I am overly ambitious about solar performance...
Not sure where the OP is or what his situation might be, but a fair bit of their content out on social media is targeted for farmers and such, to provide off-grid or stable power to areas with unstable grids.
They obviously show you the glitzy setup, but you can imagine there's quite a few who...
Not sure anyone outside the US knows about AWG (it's a dumb system to begin with, like nearly all our measurement systems).
ROW goes by cross sectional diameter in mm.
Funny, I've been on the hunt as well. I have a rooftop AC that's 12v, so trying to stick to 12v and not add more components, as I've been struggling to cleanly map out all the specific components, and an AIO seems like a much cleaner solution.
MPP Solar advertises this, I haven't found any...
...or that they're banking on the fact that people will have sold/replaced their 10 year old technology with something newer. ...or that they're banking on the fact that people don't measure their capacity regularly. ...or that they plan to not exist in it's current shape in 10 years, whether...
How are you combining them in parallel? Are you using MC4 branch connectors? Can you test the branch connector before installing? Do you have a hall effect ammeter? Can you measure current output of each section? Do you have enough wire to handle the output post-parallel?
Those power supplies are built like PC power supplies, i.e. you can't pull all 40A on one bus. I could be wrong though.
Progressive Dynamics makes a 24v charger, but it's not exactly cheap.

So I did a little research on charging profiles, let me know if anyone disagrees.
I have dual AGMs for starter batteries, and found this info on AGMs from two different sources:
https://batteryuniversity.com/learn/article/absorbent_glass_mat_agm
6 cells x 2.4v = 14.4v
6 cells x 2.25v = 13.5v...
Yeah, only lasted a few weeks. They pulled down everything afterwards.
Looks like they did something similar last November, so if you're not in a hurry, they might pop back up.
Anyone have a good method to limiting SoC? I've oversized my system by about 20%, and was thinking of invest that oversizing towards longevity, by not charging to 100% each time. This is on an RV/van, I have all three methods of charging, solar, alternator, and shore/generator. I'm planning on...
In the past, I've used a Progressive Dynamics mixed 12v/120v breaker panel, but I've decided that for this build, I will be not be using in-built 120v charger unit, there might be some other options?
Anything worth looking at? Maybe something that doesn't look it it came straight out of the...
So you jumped to a whole bunch of conclusions on what you feel, not on any empirical data. Got it.
Why would you not believe them when they say it will buck a 14.6v down to 13.9v? That's what makes it "drop-in" capable.
I believe the stated 3,000 charge cycles is at optimal conditions, the reality is I'm unable to control the temperature to a great degree, since I don't have enough solar capacity to actively cool the storage area at all times. I can control the storage SoC though.
@Will Prowse made a video...
Have you tried disconnecting all your loads before measuring the voltage?

@Digital DIY Make sure you thoroughly inspect them before your return period is over.
I ordered a pair of Grape 180w panels, and they really lack on quality control and final assembly. Not impressed. I returned them, picked up a pair of Newpowas and the difference is night and day. Would've...
Ah interesting. I did not know about Xanbus. Since there's a "NMEA2000 add-on card" for the Xantrex Marine line, maybe you can do something similar w/ their other units. That said, while I am not attached to NMEA2000, it does look like there are some off the shelf display units that you could...
