    Cinergi's 28 kWh / 4 kW Solar / 10 kW inverter RV build

    How much surface area of the terminal are they covering? I ordered them but for the studded cells I have this seems inadequate :(

    Yes. They arrived late Aug if I am not mistaken. Were kept in my storage shed prior to taking this photo.

    [SOLD] 10 CATL 302Ah cells in unknown condition, located in Oakland, CA

    I have 10 CATL cells from a group purchase that were supposed to be grade A, but clearly are not. They all measure at ~3.2-3.3v (not near them right now but can check if needed). They probably work but I don't like how they look. Make an offer.

    Rec Bms problem

    BTW, for everyone seeing this thread, there's now a new version of the WiFi module firmware that adds a bunch of features and bug fixes. I installed the update on mine and everything went smooth. My understanding is the cable issue was an early production issue that has now been addressed by REC.

    Yeah, this might be a fixable problem by securing something, but I am not yet ready to void my warranty...

    Multiplus 3000/24 buzzing while charging even at low current

Fan was measured at 63dB. Discharging was similar. Its not excessively loud but I have had a bunch of inverters that were...

    Multiplus 3000/24 buzzing while charging even at low current

    It is currently sitting on a heavy desk. I will place it on a moving blanket when I get to playing with it again. Moving it around slightly on the desk had no noticeable effect, and neither slightly tilting it.

    Multiplus 3000/24 buzzing while charging even at low current

    That's a repair I would like Victron to do, before I go and void my warranty :)

    Multiplus 3000/24 buzzing while charging even at low current

    According to the MP manual (haven't checked the MP-II), mounting in that orientation is fine: "The MultiPlus is suitable for wall mounting. For mounting purposes, a hook and two holes are provided at the back of the casing (see appendix G). The device can be fitted either horizontally or...

    Multiplus 3000/24 buzzing while charging even at low current

    I unfortunately am out of the return window. What I am considering doing is ordering a 2nd one and trying it out, and if it sounds differently perhaps I will have a stronger warranty claim that this is unacceptable.

    Multiplus 3000/24 buzzing while charging even at low current

    How come some people's Multipluses seem immune to this problem while others are not?
