No, it makes sense. I just want to read more about it, the 5-10% voltage thing is mentioned a lot on forums, but I'm not finding any nice articles that go into more detail. Like, a lot of the articles about mixed panels don't even mention this, which I find surprising.

I understand what you're saying, I guess I just don't understand why this is. I've been googling and reading mainly posts on this forum about parallel strings of different voltages, but nobody ever really says why. For almost every other solar theory/basic thing I've had to learn, there are a...

I get that it technically 'underperforms', but all 3 of those mixed diagrams above are at least 145 more watts of solar than I have now. I've been reading a lot about mixing panels, but nowhere did I read about smaller panels discharging into the larger one, have a link?

So I have a bus with 2 100w Renogy panels on the roof. It's not cutting it anymore. I have an extra 230w santan panel laying around doing nothing... so mocked this up, does this look correct to everyone? Also yes F Renogy, but this system already exists, so I'm using it.

I think they're run by marketing now.

Yeah, blows my mind that the Kidde CO alarm didn't go off at all either. WTF. It wasn't 100% blocked, but... 50%? If it was 100% blocked I think the heater would shut off. When it's crazy restricted I think the heat builds up, and there is pressure in there from the combustion, so maybe...

Durango, ish. Yes... honestly it's a glaring design flaw in all these diesel heaters. IF the exhaust clogs up.... it's still burning stuff, and it has heat, so hte heat builds up and causes the gaskets to fail INTERNALLY in the unit. Then the exhaust can start coming out the heat output port...

Even then, it won't work.

Agree completely, this product is junk. Spread the word. I am now actively going to crap all over this company every chance I get.

Hey guys, so... .. I'm going to link a video review of my experience with the Renogy One M1. This was a brand new product when I recorded this, was out for maybe a month, so I have no idea if they've fixed things now, but.... holy **** I have never been so unimpressed/annoyed/disappointed in...

Yup, this was the first time we were out there.... didnt' go very well. This forum, and YOUR HELP SPECIFICALLY, saved my ass. I owe you a beer. Since switching to victron everything has been flawless. F renogy.

Sharing a video I just dropped today; this was the first week of adventure living in my shortie school bus, in the rocky mountains during winter. The diesel heater tried to kill us, my batteries failed, and my solar system quit charging during 5 days of snow without any sunlight. Good times, but...

Here's a quick video I made about installing a CDH in my off grid shed.

That's kind of where I'm at right now, to be honest. I grounded my panels/brackets/roof to a ground rod in case of lightning. Interior is ungrounded, but I have been wiring all the outlets with continuous ground in case I want to ground the electrical side of the building at some point in the...

I searched but most answers are for huge residential systems. I have a solar 'shed' with 400Ah of lithium batteries, and 700 watts of solar on the roof. I wired the interior of the shed for AC, and my inverter is a Victron Phoenix 1200w with a single AC output receptacle. I'm unclear on how...

Edited original post, the issue was my victron system had a low temp charging protection ENABLED by default. Once I turned it off I no longer need to externally heat the batteries.

Update on this: My "self heating" litime batteries are still completely useless unless I warm them up, so this is my solution at the moment: I taped 2 seed starter heating mats on the sides of the batteries, which I have stacked on top of each other. I then wrapped both batteries and the...

I deleted my original post. You need to DISABLE low temp charging protection on victron smart solar. Then it will give the batteries juice at low temps, which turns on the battery heaters, and then accepts a charge.

Hey all, I have a fairly simple system in my bus, it's 200watts of solar on the roof, a renogy 40A mppt charger, and two Relibatt 100Ah batteries. I charged both batteries with a walmart battery charger (set on lithium) and THE CHARGER said both batteries were 95% full, so I topped them both...

Thanks Waffles. Imma just get the one for the smart shunt, less wiring to run all over the place and can keep it in the battery box, basically. Ruuvi is cool but I don't want the battery to die on it when I'm 1700 miles away.

My system: 690 Watts of Panels, 150/45 SmartSolar Charger, 1200w Phoenix Inverter, Cerbo GX connected to a 5g router with good reception, and a Smart Shunt attached to 400Ah of self heating LitTime batteries. Last winter, the batteries did not charge reliably until I insulated them and got...

My panels are used santan panels, 230 watts each. They're great for what I paid for them.

I tried saving money and installed my system w renogy MPPT charger, and renogy M1 which has wifi capability, so I could monitor my system remotely. Just unbelievable trash. The M1 system was buggy and would not connect to the wifi that my phone and laptop had no problem with, I spent hours on...

The AGMs definitely work, they are what I am using in my skoolie. They've been great!

I mean, sort of. I'm going to be using this as a cabin, and I don't have shore power, so it'll be solar only. NBD in the summer but in winter it will need as much energy storage as I can get, and since I am going to have 2 AGM batteries without a home, it makes sense to try to integrate them...

Thanks! The video quality is great, it's HD. Also, the data is YOURS, not going to Amazon or google, with zero monthly fees. And the system is expandable; I could run 8 cameras if I wanted to, all of various types. They SHOULD be okay in the winter, I had some issues last winter...

How do you do capacity testing without flattening them? Have a link? I'll google it now.

I don't have a situation yet. Just trying to figure out what makes sense to keep everything topped off when I'm not there for months at a time, and keeps the batteries topped off when I am there using it.

What about a DC to DC charger? Would that be more efficient?

That's an interesting idea. It is wasteful, but it would make a robust system. I'm just not sure how much capacity it would add after running DC to AC back to DC. Right now I have access to a 230 watt solar panel, and a 100 watt panel. I'm not sure how i'm utilizing those yet; I am...

No lithium here. Please forget I said anything about upgrading an entirely different vehicle/system to lithium.

No lithium. I have a skoolie that currently has the two AGM batteries, but it will be upgraded to lithium shortly. Then I will have the two AGMs sitting around doing nothing..... and I have this camper iwth one deep cycle, don't have the specs. Just trying to figure out how to utilize the...

Alright, here's the sitch: I have a camper with a bigass deep cycle 12v battery, lead acid. My skoolie (entirely different system) has two AGM batteries like this, but I'm replacing those with lithium, which means I will have two of these laying around, to be USED ON THE CAMPER...

yeah man read up on mixing different panels, you are doing it wrong.

Yeah I am regretting getting batteries with BMS. Or BMS I can't control, interact with, or diagnose. It's probably their stupid BMS.
