Thanks @Steve_S . I'll try that

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 yet again @mikefitz (y)

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

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

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.

Thanks Fega

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

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

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

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

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...

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...
