My goal was to be able to live normally for a minimum of 3 days with no solar input. Three days wasn't a completely random number, last year while traveling, we had 3 days of heavy cloud cover and almost constant rain/sleet/snow. I struggled with everything, including limited battery capacity...

Thank you to everyone who put up and answered my seemingly endless questions. This was an extremely steep learning curve, as I knew nothing about solar, and enough about electrical to make sparks happen. I was able to keep the 5th wheel operational with the two existing 100ah batteries and...

First time I've ever seen one, it was pretty kewl.

Even after inadvertently leaving the electric hot water heater energized my 600ah and 1200w did very well after 48 hours of normal living. My goal was 72 hours, and it looks like I'm well on my road to success. Decided to let the fridge run off electric, and it uses a lot more watts than I was...

My issues with propane accelerated this winter while snow birding. It literally became a daily challenge to keep it running. Potpourri of issues like build up on spark igniter to some unknown issue with coolant flow, to just being cantankerous. I knew putting in the 12v compressor system would...

For my TT running on a 2500w generator, i installed microair easystart. aircon went from stalling the generator to running fine. . Got a bit more interesting in the 5th wheel Multiplus II 2x. It would start the aircon, but MP went into overload, and I was scrambling to shut off anything 120v...

Thank you to everybody that has been helping with my difficult 5th wheel installation. If you're just joining, I'm already at 13'5", so higher was not an option. Total of six panels in two independent strings (driv/pass sides), 24v 200w panels. The drivers side, I left enough room for on...

My Norcold has turned into a Nevercold :( . I'm looking primarily at the conversion kit to add a compressor kit to my existing fridge. Second choice may be replacing the whole fridge with a RV specific 12v compressor fridge. Third choice might be a residential fridge. I'm leaning to 12v over...

I'd think this wouldn't be this difficult... I "think" I need either 4 port unit, or a 2 (or 4) port gland to run the wires through. Two sets of wires, each coming off three 24V 200 watt panels. going to two SCC. Found a set of glands on Amazon, ship between Feb 3rd to Mar 3rd. Trailer did...

I pulled off the Rich Solar 12v panels and replaced them with 24v. I was shocked to find two attachment screws that worked their way loose :( Guess this will have to be an annual inspection point. It's kind of late to think about loctite in my setup. I really don't want to pull the panels...

Trying to solve a problem with keeping a home server up and running while we snow bird. I have a gel battery surge protector inline... but it's only good for about 45 minutes. Thinking about a solar generator that will be plugged into shore power, but what will that due to the LFP battery...

I've seen all kinds of claims, 3-4a all the way up to 25a. 2022 F350D, towing a 5th wheel, solar input current was shut off, so the only source of energy was from 7 pin going into the battery. i intentionally ran the 5th wheel Lithium battery banks down pretty far. I have dual alternators...

I'm nearing completion for the 12V system. !20V will take a bit longer. Hoping to {shudder} put a hole in the roof tomorrow, but think I have a plan for that. I bought 100' of red and black cable, but 25' may have been enough :) Wire is pulled 1/2 way up the wall. Not totally happy with how...

The recent week long power outage was not kind to my server and network. I have a small UPS with unknown AGM battery condition. I currently do not have the USB cable connected between server and UPS for "smoother" shutdown. The hard shutdown caused some issues which I can not resolve until I...

I can get three 200w panels on each side of the RV, for a total of six panels. Plan is wire 2S 3P. Shading from junk on the centerline is a problem depending on trailer orientation. It will get worse with adding these panels. Should the panels in series be on either side of the the...

Attempting to save money and bandaid my RV factory installed system is getting out of control. Came with 215w solar and Zamp 30a charger. I've upgraded solar to 470w doing my best to match voltage. 200+170+100 Currently with 200ah LIFeO4. First thing to go, Zamp charger. Planning to go to...

2022 Arctic Fox 27-5L, 50a service Zamp factory 30a controller 2 port cap on roof one 45w panel & one 170 panel Rest of planned configuration upgrade below the solar questions Looking to put on another 170 panel and had a heart attack at Zamp's cost of $599. Led me to HQST 190w panel. Zamp...

I was planning to run wires (50a) from the back of the trailer to the front and back again. Trailer was prewired for ATS and I had installed a 50a inlet on the front of the trailer for that and an inverter (50a plug on it). Thinking this through further, and it's beginning to make sense to use...

I currently have 1200w on the roof. Started with factory limited amountn, added to it, taking off one panel... Four mounting holes patched Added an additional panel Took off the 2nd factory panel and my new panels, eight holes patched Added six new panels It looks like at least one panel mount...

During my recent trip, LFP bank (600ah) got down to 20% due to several days of very limited solar collection. I was leaving later that morning and decided to start the generator for a short period of time. Generator is 2200w running capacity, I set limit to 18.5a. Couple of interesting...

I have a car that will sit for a couple of weeks at a time and is stored all winter with a trickle charger. The factory battery is now 13 years old, about 5 years ago, I hit it with a homemade desulfator, which worked well. I no longer have the desulfator, but think it's time to replace the...

Rather than toss or sell them at a huge discount, I'm going to keep the two 200w 12v panels for ground deplyment and use the side wiring input. But I need to be able to support them. Weight and ease of use are critical, along with as flat as possible for storage. I may regret hauling the...

Woke up this morning to clear blue sky. Started the AC to run the batteries down a bit. By the time the shadow from the trees cleared, there was a thin cirrus layer and then some thinner cumulus clouds developing :( Someday I'll see what my 600w (per side) can truly achieve.

I see absolute storage, no energy going in or out should have a limit of 80% SOC, What about some usage? Right now, 5th wheel is not being used, but I'm leaving 120v and 12v running, and vampire parasitic loads pull about 8% every night (600ah total capacity). Second somewhat related...

I had a plan.... apparently not a good one :( Original plan was to pull wires using the existing wire going to the roof gland and over the hole with a project box, used as a combiner. For once, wires are stabled or otherwise restrained. There are two sewer pipes going up in the same cavity I...

15a total coming from each of two separate strings (1s 3P) to two separate SCC. Each panel lead is fused going to combiner. Can I use a non polarized breaker as switch to turn off energy coming from both strings of panels, only positive lead? 2nd question, two victron 100/50 SCC, I'm assuming...

I ran about a 10' of 16g to a 12v blue sea outlet through a 10a blade fuse attached to the buss bar. I use the outlet to run 12v native powered freezer. Freezer is reporting about -1.0v to what I'm seeing at the buss bar when the compressor is running. It's difficult for me to get to the back...

For grins, I started it on 12v... it hit the battery bank much harder than I expected. It was an experiment, and took about 20sih hours to finally cook down, and hit my 600ah battery bank for almost 500 amps. It was an empty fridge. I so need to either upgrade this fridge to 12v compressor...

I mistakenly thought that batteries in parallel somehow magically shared the load. Boy was I wrong, and may need to do some rewiring. Positive point, even after 20 minutes of running in overload, my worst wire was 5F over ambient.... now I understand why. I was expecting one of two things...

5th wheel came with PWM, which was removed and replaced with two VE MPPT. Also have two 200w panels that are currently holding up a wall in the shed. Can I ground deploy those two panels and wire them to the Zamp PWM attaching to the buss bar? Thinking of using those primarily when I need...

Our snowbird site is going to be on 30a site (50a 5th wheel). Limiting power inlet to 30a, does this mean I will have 6000w (3600 + 2400) available and shared across both L1 & L2? Main AC has EasyStart installed, and I have yet to need both AC units running at the same time. Last winter there...

Well, I thought I had a mixed energy supply plan... not working so good. Generator is Westinghouse 2500 - 2200w running, power limited to 18a, or less. I know I can run my main 15k AC just off of battery, for about 5 hours, 600ah battery bank. Actually had both AC's running with generator for...

I thought when I first started my system up, I could see the Cerbo display on my phone with local access. In the process of setting up remote access, I seemed to have lost the local display. I can still see it with online portal, but not local. Doesn't matter if I try and connect to the brain...

I'm not understanding this chart in the manual. Planning dual 100/50 with 600w on each unit. . How does the same panel double the Watts based on battery voltage? Specifically for my install, I went with 24V panels expecting SCC to maximize energy flowing into 12V battery bank. Now I'm afraid...

I think I saw the cable is 2 meters long. To put the cerbo where everything else is going, I'll meed approximately 3-4 meters. Is this doable with longer or extended cable?

I took my infrared thermometer and measured temp of each terminal. Ambient temp where the batteries are located, running 58-59F. !50 amps pouring into the batteries, and the highest post temp was 63F (pos). It was interesting that battery's neg post was 61F. Temp was measured about 45...

Any reason to install a switch on heated batteries, or just leave it and let BMS manage turning the heater on and off as needed. My batteries are in the unheated front compartment, and while I don't expect to be in cold temps, this year especially has shown it can happen.

Nearing startup. I originally was going get 12v operational before getting 120v going. Going to go ahead and connect 120v wires while the 12v and 120v is off. Panels are all confirmed wired to correct SCC and polarity is correct Turn off 120v disconnect 50a cord turn off and disconnect...

Going to add 2 left over panels as ground deployed, planning to use the Zamp PWM that I took out of the system. If I like it and works, I'll eventually upgrade to VE MPPT. I'm expecting to need aircon for a 5 day off grid, and the extra solar will be nice to have. . Any concerns with just...

I kept two 200w 12v panels that I removed when I upgraded to 24v panels. We have an event this summer, and going to set the two panels to supplement roof panels. For this event, trees will not be an issue. What's a good wire length to get started with?

Is there a place to retrieve detail current data from a couple of days ago? I installed Microair Easy Start and started the AC running strictly off battery, and boy did it struggle getting it going. After installation, it didn't even break a sweat. I'm just curious if there's enough detail...

According to my smart shunt, I was getting a whopping 25a going into two 100a BB Lithium 12v batteries. I know the interconnect cables are large enough. I believe the factory cables are 6g from the charger to the buss bar, about 25' one way.. Batteries were down to 20% when I turned the...

2400 watts 3000 watts qualified by this note: Non-linear load, crest factor 3:1 What is non linear load?

Current config Power Supply --> Automatic transfer switch --> EMS --> Power supply I thought the ATS was in the front of the trailer, it's not, it's in the back :( Now I have to run two new cables from the back to the Multiplus. Do I run multiplus between ATS and EMS or after EMS? I kind of...

Mixed use of Zamp and other brand panels (470w). RV came with Zamp panels and Zamp 30a controller. I've since added two 100ah battleborn batteries, and upgraded the Progressive LI charger. Neither the solar charger, nor the 120V charger go into bulk mode. Progressive is blaming the solar...

Installing two 100a 12v Li Battleborn batteries. I bought 2' long 2/0 to parallel the batteries. Called BB today to confirm the wire size, and they said they would have preferred 1/0, because 2/0 might have too low resistance, but I'll be ok since it's only 2200w??? This is where I get really...

According to Victron's published docs, 60a is max current on the 50a SCC. What happens if you go over 60a? Is it a hard limit like VOC? If it was hooked to say (random number) 1000w on a 12v system, would it release the magic smoke?

Changing Lanes did a pretty big set up with Volta prototype equipment. I'm not familiar with the battery chemistry they used. It's also looks like a complete AIO system. The estimated cost is a lot more than I'm willing to spend. Link to Changing Lanes video

qty =4 12v 100ah in parallel, possibility of going to 6. T Class? What size? i will have a victron multiplux 120v x2 connected to the 50a circuit. Also what size interconnecting wires? 5500w peak power, 3000VA continuous, 2400w continuous from the multiplus docs.

What is the risk of not topping off batteries before adding them in parallel to an existing bank?
