And that attitude is why many RV fires start because someone inadequately wired their inverter.
It's not just about you, but anyone who uses your RV in the future. That's one solid reason for code!

I see the person losing my respect is you, Blackhat, and you've provided no worthwhile input. I certainly don't read elewis's posts as negatively as you. You've made your point and so has elewis33. How about both of you move on.

Last January something was causing our AGM batteries to get too low a voltage overnight. Our Victron BMV-712 monitor's history showed us our batteries had received 21v at some point in time. I reset the monitor and the next day it showed another 21v charge. It was intermittent and we were at...
Actually the answer would be "Yup." I stated "The WFCO could probably keep your batteries at 80% or more (just an off-the-cuff estimate)" Again, that was "80% or more" and 95% is simply "more."
Many charge to 100%, and for them it's a point, but I could care less if it's 95% (choose an upper...
We've had excellent results with our Victron 100/30, 100/20 and BMV-712. All three are their Smart products so have bluetooth accessibility. They all work together and are accessible from my phone when driving down the road.
Enjoy,

Last February we purchased a set of 260 ah Soneil silicate-salt/lead crystal/silicon dioxide (SiO2) batteries. I believe they are all the same, just using different descriptions. I'd been looking at lead crystal batteries for years and after our AGM's failed, from a bad WFCO, decided to pull...
We went from 220ah of AGM's to 260ah's of Soneil's Silicon Dioxide (SiO2, or lead crystal) batteries.
The difference with charging SiO2 vs AGM was quite dramatic. Our SiO2's charged much, much faster with the same 170 watt GoPower solar panel. In the winter in Arizona, the GoPower PWM SCC...
This morning I went down to the camper to install the 200a Class T fuse and it doesn't fit. Turns out there are at two sizes of Class T fuse holders. The smaller is up to 200a and the larger is for => 225a. I have a 200a Blue Sea fuse but a 225-400a Blue Sea fuse holder. The inverter...
Perhaps I'm reading this wrong (I'm dyslexic), using 40% of your 340 ah's at night seems quite high for the camper in your schematic. What loads are you running at night?
Enjoy,

Nice neat install! I wish we had that much room to work with. I have to use three portions of walls in a u-shape dinette plus a vertical board on the battery box for our install. The board will be attached to the battery box with Velcro and anchored to the floor with two shelf brackets...
22.44 X 7.1 = 159.3 watts
14.19 X 10.9 = 154.7 watts
There is always conversion and line loss, so not much difference here.
Depending on hour your BMS measures vs Victron measurement will explain that difference. I'll let someone else handle that.
Neither device is 100% accurate, but is...
We have 465 watts on the roof. The original 170 watts was not enough many times, so we added three 100 watt panels. Wired in parallel only lost 5 watts (would have lost 65 watts in series for only 405 watts). Our 170 watt panel never got over 150-160 watts in June/July and we wanted about 100...
In your schematic it says you're installing a "Solar MPPT - Victron 20 amp" SCC. We have a Victron 100/20 SCC and the bus on the 100/20 is a joke and barely accepts 10 awg wire. Will had the same feeling on the 100/20 he tested. We also have a Victron 100/30 SCC that has an acceptable bus.
I...
As far as I'm concerned is isn't worth a tinkers damn if it doesn't keep history. We don't sit and watch the meters endlessly. The AiLi and Renogy's are only meters (I see Will finally came around and now calls the Aili a meter). Neither the AiLi or Renogy (or many other meters) would have...
It appears you're running the batteries with a 24v scenario. If so, your bulk charging voltage is a little low at 28.2. Your attached jpeg states 14.4 to 14.6, so your bulk charging should be set to 28.8 to 29.2. We charge our SiO2 batteries (lead crystal) at 14.6 (29.2 in a 24v setup)...
I have a Orion-Tr Smart DC-DC Charger Non-Isolated that I would like to reverse for a whole-house voltage controller running at 12.8 volts. I don't like the idea of my trailer's appliances seeing 14.6v during the day when we have solar. Will this work efficiently in our trailer, or do I need...
It sounds like your batteries are full (13.2v or greater). If so there will be no or very little amps from the SCC to the battery bank. If your batteries are full then your SCC is doing it's job.
Shut your panel(s) down (switch your Blue Seas breaker off), use 20 or more ah's, and then...
Since my original post I sent back the smaller Class T fuse holder and have installed a larger holder with a 250a Class T fuse purchased from West Marine for $52 plus tax and my drive to their store. I since have purchased two backup fuses (which Murphy say's I'll never need) from Best...
I don't see anything with a larger draw than his inverter. The ANL fuse next to the battery should be sized to what the inverter manufacturer recommends, protecting his inverter wires. The smaller devices need their own fuses. I have a 250a T fuse next to the battery, a 30 amp fuse for the...
Actually neither of us knows which went first, the inadequately prepared roof/mount or the gel coat. My guess is the one with the gel coat was the only one that was prepared properly, but with the other three failing the gel coat was overleveraged.
Many mechanical fasteners have failed on...
That's one reason why I used 2/0 rather than 2 awg. A fuse that's too large does not protect the system. I won't go there, because that's how you melt wires and fry batteries, a major cause of RV fires.
Your largest load should be fused at the battery. Our 1500 watt inverter should only need...
Some use Eternabond, others use Dicor self-leveling caulk, but I use zip tie mounts. I remove the existing tape with a knife and then use 3M VHB tape for better adherence. After using the zip tie I'll cover the edges of the mounts and the zip ties with Dicor to help prevent UV issues.
