when the mppt is in abs the shunt say 80 or 90% so that is how i see that is not correct.

thx for the tips.i have set the Victron default values,14.2 absorbtion and 13.5 float .the charged voltage in the smartshunt is set to 14.16 ( the app say 14.2) i hope this fix the issue .

so the mppt absoption voltage set to 14.60V and the smartshunt charged voltage also set to 14.60V?.and the rest of the settings are ok?thank you very much

Best, I have a lifepo4 power queen 12V 200ah battery. I monitor this with a victron smartshunt. I have the impression that the smartshunt is different. I am adding 2 photos of my victron mppt and smartshunt. Can someone please tell me if the settings are wrong? I also asked this question to...

hello, I want to place a heavier 170w panel next to my existing panels which I have already indicated above, but in a separate string.I have another Victron MPPT and I want to connect it to my same battery. So 2 MPPT on the same battery bank.specc of the other panel are Maximum power (Pmax)...

thx.what size?also 200A?

my brother-in-law bought a power queen 12v lifepo4 200ah (200a bms). He will use this with a 2000w inverter. Should he install a class T fuse here?or just a mega fuse?

So I want to take a different approach.i have 3 50ah lifepo4 powerqueen batteries.if i connect them in series than i have 36V ( 1920wh if im correct ) i can set my victron mppt to 36v so i only need a 36V inverter.It actually comes down to the same thing, but then I don't have to secure the...

I'm not saying that you don't know anything about it. I'm just saying that I saw this on Facebook. For me it's confusing because I still have a lot to learn.so thanks for all the tips(y)

yes i have a main fuse for the cable. but this is a fuse for between the batteries

on facebook someone had 3 100ah redodo batteries in parallel and he said you can place a fuse between the batteries but it is not necessary.of course happy with what he said. I saw what an MRBF fuse costs, they are not cheap,I should already have 3 MRBF fuses in my system...maybe a 4th. I was...

according to the manual, a 50ah battery can reach 100a for about 3 seconds

thx.my setup is like in the diagram only not connected to a busbar

I should check the manual to see what this 50ah battery peak current has.then I will have to place an MRBF Terminal Fuse Block of around 50a on each of the batteries so that if a short circuit occurs in one of the batteries, the fuse will blow.but it is not if I use for example 120a that the 50a...

I read it. I didn't know that myself. I see a lot of DIY on YouTube that have the same connection as I see in the photo.So you don't have that problem with 1 large battery.to connect all 3 batteries to a busbar I would have to buy new cables of the same length...or make them the same length.

I also have the cheap busbar from Amazon, but I rarely exceed 120A. So I understand that every battery must have a fuse. My main fuse is a mega 150A.what size should the fuse on the battery be?then I will look out for MRBF fuses

thanks. so i need to fuse each of my batteries in parallel. i have a 150a mega fuse close to the battery.

first and foremost a happy christmas. i have 3 50ah powerqueen lifepo4 batteries in parallel.I want to buy another 50ah battery so that I have 200ah. Is it better to have 1 200ah battery or 4 50ah batteries in parallel?Should there be a fuse between the batteries connected in parallel?thank you...

the panels have in serie 90V so that is to high for the ecoflow.i can charge the ecoflow from the diy...so that is the easy way yes.but I thought there was an easy way with a step down converter. But as you say, that makes it much more difficult

If I want to connect the panels to my Ecoflow I have to connect them in parallel. If I want to connect them to my DIY solar system I have to connect them in series.What I mean by this is that I don't want to connect the panels in parallel or series every other time

I know I can connect them in parallel. But it is not the intention to constantly connect the panels in parallel or series. Is there no other option?

I have an ecoflow river max. the input is 25V, 12A max. now I have 4 solar panels in series.i know the voltage is to high for this powerstation.Is there a way to connect it to these panels with some kind of step down converter or something like that?To be clear, I use these panels for my DIY...

yes, I saw this video on YouTube. If I'm not mistaken, it was very expensive.

thank you. I have an ecoflow power station in addition to my DIY solar system. That's why I thought about purchasing a flexible solar panel because I no longer have room to put another glass panel.

what do you think of flexible solar panels?

found only 22mm A little bigger doesn't seem like a big deal to me

thank you very much. I will look on amazon for 20mm conduit.

nope.just the red and black cable.

oh yes:) there are only 2 cables, the plus and the minus

maybe a stupid question but I want to protect my solar cables outside with a Conduit (not underground).I use 6mm2 cable,what size of conduit can I use for this?thx

Hello, just a question. I have 4 solar panels in serie that are connected with a 15M 4MM2 cable.the problem is that it is winter now and the panels are in the shade.I now want to put them further away where the sun does shine.but from my home to where I want to put the panels is 40/50...

So I placed a 150A mega fuse on the cable to the inverter and a 40A mega fuse on the cable of the MPPT controller. Thanks everyone for the great help!and brad I'll see you again on youtube;)

That's a nice setup. Still too complicated for me. I'm happy that I could put together a small system like i have.thx for sharing.

typo...yes this fuse is not suitable i know.i have to change it with a 40A mega fuse.
