    Can a fully programable PWM charge controller safely charge a Lifepo4 Battery?

    I’d like to understand why they don’t recommend the panels Voc to be over 21V. Aren’t they admitting that there is a risk of over voltage with their controller with this very statement? EDIT: I see that they were referring to their 2030 unit. I understand the concern now. This seems like...

    How to create 2 input sources for SOK

    You may want to get a service manual for your Jackery and see what kind of wizardry they use to adequately charge a LiFePO4 battery using both a standard cigarette lighter and solar panels. There has to be some type of charge controller they use but I’m concerned that even if you figure this...

    100w single panel setup advice for shed

    Sunsets are amazing but we don’t go there until late spring. It’s too cold this time of year and my wife and I are full time RV‘rs so we are currently set up in Gulf Shores AL enjoying the weather here until then. Most outdoor lighting is 12V so I think this should be pretty easy to do...

    100w single panel setup advice for shed

    Well, I think you are on top of it all and you know your limitations and expectations. I’m also certain that you’ve had fun messing around with it all and I know that you know where to get advice so you are well in your way to success. I’ll be doing something very similar to my storage shed on...

    100w single panel setup advice for shed

    That would take almost two months to charge 50Ah worth of battery. You’re going to need more panels my friend.

    Sok battery size difference

    Not sure if I would recommend doing that very long though. I like the fact that it has its own Bluetooth BMS. Wish SOK offered that.

    SOK batteries

    Not how much simpler I could have been. It might be time to buy Wills book and learn some basics. If you don’t understand what you have, then I suggest you might not want to use it for fear of ruining it. Im not sure if there was a question in your last comment to help you become a little...

    Battery bank replacement: drop-in LiFePo vs diy

    Watch Wills latest video. If it were me, I’d buy one of those EG4 Server Rack batteries. Has everything you need without the hassle.

    SOK batteries

    With 400 Watts of solar you are best off with one battery NOT two. It’s going to take a while to charge two batteries unless you purchase more panels. Get a 100 Amp fuse or breaker for between your inverter and battery and don’t ever plan on using more than 1000 Watts from that inverter until...

    iPad Pro App to draw circuit diagram of my solar/boat electrical diagram

    I suggest Affinity Designer in the App Store. It’s great for creating flow diagrams in my opinion. Another great option that is free is https://www.draw.io/

    Best practice for cleaning and protecting connections?

    I appreciate your experience and honesty. I agree, I’m probably overthinking all of this with a 12V system. I really just don’t know how much that I don’t know and I’m glad I asked. Thank you!

    Best practice for cleaning and protecting connections?

    I agree that everyone’s situation will be different. In my case, my system is located in the front storage bay of my 5th wheel. So it is dry but it is susceptible to outdoor humidity. I oversized my cables, lugs, busbars and everything else from the get go. This gave me the piece of mind that...

    Best practice for cleaning and protecting connections?

    After designing my system and making all connections, I’m concerned that I don’t have proper and safe connections for longevity. All my connections are with new lugs but I didn’t sand them down or clean them in any way. I just crimped them and torqued to specs and called it a day. What is...

    New Guy, Off Grid in Baja, replacing old 12V system.

    If you stick around the US long enough it will be very similar to Mexico. No need to go to Mexico to live under government control, poverty and cartel drug rings. Coming soon to a neighbor near you! Sorry, just saying. I apologize for going off topic. I love the people, culture and family...

    What is a cycle?

    When using the victron shunt, if I ever need to disconnect the battery for any kind of maintenance task, I simply go into the battery setting and get the current soC setting as seen by the shunt which is accurate to the tens position. Then after I’m done with my maintenance task, I manually...

    What is a cycle?

    SoC. but its based off of the battery size and current draw to determine how many Amps you've used. Not sure how much is actually learned from these devices without you inputting the correct values in the first place. You shouldn't use voltage to determine a batteries SoC anyway unless the...

    What is a cycle?

    Within the Victron app, a charge cycle is considered charging your battery between 60% and 90%. It's that simple. You have to drain your battery to below 60% and it needs to be charged back up to 90% . It will then add a charge cycle to the count.

    It's "loses", not "looses" (and other grammar lessons)

    When we live in a world of autocorrect, I think we get lazy and don’t proofread in our haste. I personally could care less what people mis-typed as long as I understood what they meant to say. Especially on a forum such as this. What really irritates me is when people think they are...

    50Ah are never going to be enough. Not even close. Do an energy audit first.

    Hello All First Post Solar Design

    It really depends on the vehicle and how it is set up from the manufacturer. My 7 way only sends about 13.4V when it’s on and even then I’m lucky to get an amp or two at most if my LiFePo4 is lower than that voltage. However, if my truck is off, the voltage goes the other way and my LiFePo4...

    Hello All First Post Solar Design

    If there is a short between the bus bar and something else in the RV other than the inverter, which fuse will break? Personally, I would want the one that would terminate all connections coming from the battery to trip for obvious safety reasons. And if there is a short between the inverter...

    Hello All First Post Solar Design

    That is smart to keep the brakes separate from what you added. I agree. I also agree that everything that is connected to that busbar should also be fused based on its current needs. But I was specifically talking about the inverter. Again, that entire current from the battery to the Inverter...

    Hello All First Post Solar Design

    Just to jump on this thread and ask a couple of questions, I’m a little confused with some of the observations and suggestions. First, I have a very similar setup. You need to be careful with installing a cut-off switch between the battery and the bus bar. If your switch is off, you won’t be...

    RE: A/C powered charger: can you parallel 2+ of them?

    I can’t imagine why it would be an issue since people use multiple SCC’s on their battery banks along with a DC/DC charger along with other charging sources. But, as others have stated, you have to make sure that you’re not suppling more Amps than the battery can handle. If it were me, I...

    Newcomer RV solar help

    Besides the weak link being your battery, the next issue is your stock converter in the RV. If you replace that single lead acid battery with a couple of AGM’s, golf cart or a LiFePo4 battery, expect to run that generator a minimum of 5 hours with the stock converter(probably closer to 8). You...

    Creating a portable RV solar system

    Basic setup but no need for more ATM

    My generator has a remote start and is wired to my shore power. Had to make a bonding plug for it since I also have a hard wired surge protector installed. If I need extra power to run the A/C or air fryer or something, I can just push a button from inside the RV and it takes about 30 seconds...

    Basic setup but no need for more ATM

    Your exactly right. It has a LiFePo4 profile and because it is running thru the default RV shut off an has a long cable run, I’m only getting about 30Amp output instead of the 50Amp output that it claims. It’s better then the 10Amps I was getting from the old controller and I only need it on...

    Basic setup but no need for more ATM

    The single battery will get me by but will be the first thing I address when the need arises. I’d definitely purchase a second one and parallel it. Panels are connected in series configuration. I have a lake property that I spend the summers on. No electricity on the site but I do have water...
