Thanks for the replies. Everyday a school day, I wasn't aware of the fact that SPD wear

Thanks Fega

Thanks @Steve_S . I'll try that

Thanks Mike, I'm in the UK. As my batteries are connected in series should i also be using a battery balancer or can i get away without one?

Thanks again, much appreciated! My mppt has a visual display which indicates SOC so i will have a play with the settings and see how i get on

Hi, Can anybody explain to me the logic my Tracer 8420AN uses to enter into boost charge. I have the boost reconnect voltage set to 24.4v (i'm running agm batteries). I understand that the controller should enter boost charge when the batteries run down to 24.4v but this is not immediately the...

Thanks for your help ! :)

I'm using adaptive absorption on my Victron 150/85 mppt. The default setting for tail current is 2A to exit absorption and move onto float. Im running 2 x 260Ah AGM @ 24V. Is there a general rule on what tail current figure to use relative to battery size? I'm also VE. networking a victron smart...

Thanks for the info, so the combiner will give me a parallel output. That makes sense

Hi all, I'm running 2 X 260Ah AGM batteries wired in series @ 24v. Cycle use of the batteries are specified as 14.4 - 14.7v (28.8 - 29.4v @ 24v) Float / standby specified at 13.4 - 13.8v (26.8 - 27.6v @ 24v) I have some questions; I have programmed my mppt bulk & absorption voltages at...

Thanks for the reply Bobert, do you suggest that the diagram in the second picture would be ok to connect to 1 mppt?

I'm unsure how to determine tail current value from the data below

I have a Powerstar LW LF inverter (24v 3000w). I've noticed that its started to make a humming noise when there is a small load. This happens when the fan is not running so i don't believe its fan bearing noise. When i increase the load the fan kicks in and when the load is reduced the humming...

Thanks Mopat, I've adjusted the settings to see how i get on

Thanks for taking time to reply RC and thanks for the detailed information. Sorry if I was not clear.. Currently; float charge voltage is set to 27.6v Bulk & absorption set to 29.2v (reduced slightly from 29.4v in my original post) I was referring to absorption time as this is an...

What size surge protector should i be using for my 150/85 victron Mppt. I originally ordered a 100v SPD but the supplier sent me a 150v SPD instead. The SPD will be mounted within my PV combiner box. Can i get away with the 150v ? Just wondering how others size their SPD.

At the moment I have a fuse on the positive battery cable only. My question is, Should I fuse both the positive and negative cable between the Mppt & battery? Can anyone advise on an ideal switch/fuse to use? I currently have a midi fuse installed

Thanks yet again @mikefitz (y)

That's very helpful thanks Mike, My controller is epever Triron 3210N (100v max VOC / 30A) Batteries are 2 X Lucas LSLC260-12 wired in series @ 24v 260Ah

If anyone has a link to a suitable battery monitor it would be appreciated. I was wondering if it's worth buying a victron monitor and shunt although I see cheaper ones on Amazon/eBay. Does a battery monitor & shunt have to be connected to a fully charge battery to provide a reference point or...

Thanks for your input Substrate The batteries i'm using are brand new and i ensured that they were fully charged before connecting them up. Thanks to Mike / RC i've now installed the victron smart shunt which seems to be working well although i'm still playing with the settings. This time of...

Please can someone help me. I want to know what the output voltage and current would be on the diagrams below. I assume i'm correct with what I've written in the second picture but wondering what the output would be for the first picture. Thanks
