    Batteries won't charge on small solar system

    Soc memory issue? Could the shunts somehow be remembering values from before and now need recalibration for new soc values?

    Forum Technical Issue?

    Thank you for the workaround. Having the same issue myself. It started yesterday for me. Edit seems to be working now

    General Battery advice

    As a fellow newbie I am intimidated by the diy lifepo4 option. Be sure to check out the up in smoke forum before you go that route. One advantage of individual components over the aio is if you purchase things with your 48v goal in mind a lot of your learning system costs will also be your...

    Couple of Questions About Charging Requirements in Relation to Resistance.

    I get that usage, pv input, and bank size all correlate. What I don’t get is why a 50v array at 8amps would be bad for a 24v 500ah bank. Lets go with 500w daily usage at 20-25w constant load. In another thread it was mentioned that a 20a charge rate was killing some lifepo4 batteries that...

    Couple of Questions About Charging Requirements in Relation to Resistance.

    A missed opportunity for education. While the answer is in the question for newcomers trying to understand bank sizing and how everything works together this could have been a golden thread of knowledge. I’ll keep digging for the nuggets of wisdom.

    Multiplus 3000/24 buzzing while charging even at low current

    😂 “Hey honey I need you to lay right here while I plug this in…whomp, buzz slap”

    A thread on battery carts.

    In the spirit of DIY I went with some 8” heavy duty castors for the base of my project. At 771lb load ratio each they should handle a few hundred pounds of batteries gear. When I get something built I post it in the thread. For now I’m eyeballing this old upright freezer with a circular saw...

    Victron MPPT over panelling

    My understanding of overpaneling is case #1 where you have more input capacity than output ability but are still within the scc voltage and current limits.

    Victron 'Smart' Solar MPPT's / Manual on/off

    Phones break. I’ve yet to get all my pieces together to see how the software side works. Do you need an isp or just a local network? In a remote location sometimes one the other or both are just not available.

    "regular" solar system or portable power station?

    if it meets your needs and budget awesome! If it sees full charge/discharge often it might last awhile too. Both have advantages. They are the true AIOs. Highly portable. They meet a variety of application ranges at a decent price point.

    "regular" solar system or portable power station?

    Biggest difference I see between is applications. The portable power stations are not meant to be a 24/7 duty cycle piece of equipment. Sure it will work until component failure which is likely battery first. Use it daily and never cycle it I’m betting it dies quickly. That is where your...

    Connecting a PV panel to a Portable Power Station

    65w-100w max charge rate. Anything more would be a risk imo You might be able to hack a buck/boost type module to the dc jacks.. run the solar to a terminal bar and then charge thru all 3 but then again the batteries or bms might decide they don’t like that. If it were me i would find...

    12v 10a 230Wh 18ah system with low temp protection under $200 without panels

    Sure you don't sell batteries for a living. *jk Thanks for setting me straight on that too. As you said learning is a constant process and you have to be receptive to all the information not just the bits you want to hear. I also realize there is some tool investment to be made. Tools are...

    12v 10a 230Wh 18ah system with low temp protection under $200 without panels

    I thought that was how I understood the mrbf break ability from another thread. I wanted to be certain. I also understand the copper washer thing. It is acting like a busbar and is sized for the load. I did find it interesting that you ran the input from charger and output to inverter on the...
