    Series Parallel panel wiring newbie question

    So if you have to setup a battery monitor shunt and set the point when the battery is at 100% charged to start the monitoring how would I know when my battery is at 100% SOC with my current system. Would it be as soon as my battery gets to the new float voltage of 27.2v while charging and then...

    If I go to having two batteries, would I ideally want two shunts to be able to see each battery individually or just one for the combo or them?

    Do you think my float setting caused any major damage already? ?

    Series Parallel panel wiring newbie question

    I'm planning on getting a second mule 24v battery to add in a few weeks when they get them in stock. I've already ordered it. Should I get one of the Victron shunts that have the option to monitor a second battery in this case?

    Thank you so much for clearing the float charge up. I've been worried about it and feel like I haven't gotten clear answers so I feel much better now. ?

    I've changed my float to 27.2v now.

    My understanding is that MPP reports SOC via voltage. There is not even a option for defining the size of battery.

    This is exactly what I've been asking Big battery directly and ShopSolarKits.com. I've asked repeatedly if my bulk and float both should be 28.8v. I said this doesn't seem right from what I've read and seen elsewhere. They both said it's right. Follow what is in the specs! ?

    Series Parallel panel wiring newbie question

    Am I paying too much attention to the voltage? I'm looking at it like the state of charge percentage on my little Jackery portable battery I guess. The state of charge on my MPP display seems totally unreliable. So what do I go off of? I was expecting to see the the voltage slowly come down from...

    Series Parallel panel wiring newbie question

    Today I had my inverter off and no load on the battery. It was a good sun day and my battery was taken from a steady 26.6v resting voltage to a fully charged 28.8v and PV power was reduced during mid day by the system in order to maintain the full capacity. This all made sense to me. When I got...

    Series Parallel panel wiring newbie question

    Yeah I get that. This was only comparing like a week ago to now so shouldn't be that much difference but I am waiting for a really clear sunny day to really get a comparison before I make any changes back to 4S. It may just be that we had some really bright sunny days a week or two ago and the...

    Series Parallel panel wiring newbie question

    Ok, I will have to watch for that next time I have excellent sun input and if my battery is peaked out. I haven't been up to my 28.8v max for a while now since sun has not been at it's max. It's been cloudy most days with brief times of good sun but even these brief times just seem to be lower...

    Series Parallel panel wiring newbie question

    Is it possible that I would get less performance going to 2S2P vs my 4 in series before? I haven't seen the higher wattage (600w+) that I was getting before on 4 panels in series. I mean it has been overcast some of the days like normal but on the clear days I haven't seen it get as high as it...

    I just switched to 2S2P so will see have to see how it compares to what I got today in 4S. Will update.
