    Victron Multiplus 2 buzz

    Has anyone experienced a vibration/buzzing from (I think) the small coil winding within the Multiplus II? I don't recall it making this noise before, and it's very sensitive to just tapping even the outer casing of the unit slightly. And no it's not the main transformer making the nose! All...

    Low solar power output

    Prior to upgrading to 48v, I ran a 24v system, with the solar capped to 60a. 8x 265w panels wired in 2s4p. Whenever the sun was out the controller always seemed to be capped at 60a (1.6kw) or there abouts. Now on 48v with a much higher PV input, I seem to be getting less power. I mean, it's hot...

    48v has damaged my SCC?

    Well here's an annoying one, I've run a Morningstar TriStar MPPT 60a on a 24v system for a couple years now with no problems. I decommissioned the system for about 3 days whilst upgrading to 48v, and then flicked the dip switch on the SCC to 48v and connected that too. No life whatsoever, well...

    Using an External Charger with Victron Multiplus II

    Just trying to wrap my head around this.. I'm upgrading my system to 48v, and will be using an external AC charger to charge from my generator, This is to prevent dirty passthru power supplying my loads. I'd like to accurately monitor the AC charger current and history, so I will fit a smart...

    Using Server/Telecom power supplies as battery chargers

    Soon will be upgrading to 48v with a new Victron Multiplus, but I'd like to get away from using the dirty geni power on passthrough. Trying to find a 48v 70-100a charger is proving difficult (EG4 not available in UK) I've come across some Eltek Flatpacks which are readily available here, two...

    Good deal or not worth the hassle..?

    So picked up 9x of these 255w panels for 5p (6c) per watt. As you can see they are shattered, although most of the panel actually feels smooth bar around the edges. Possibly a bit of an impulse buy since I wanted another array and these were cheap. Is it worth just putting them up as is? Any...

    Multiple component sale.. UK

    I'm going to change my system from 24v 3000va to 48v 5000va. Been debating changing a few components and it's more cost-effective to import 16 batteries rather than 8. So.. I'd be willing to sell - Victron Multiplus 3000/70/50 (labelled muti-g but the same thing) running latest firmware...

    Pairing Victron Equipment with different brand SCC's.

    Been a little conflicted on what to do with my system as I upgrade.. I currently use a 3k Multiplus, victron battery shunt and an older victron battery monitor with a CCGX (soon to become a cerbo gx I think) running from 24v 280ah of lifepo4. My current SCC is a Morningstar Tristar MPPT 60a...

    Which water heating element

    Currently I live completely off grid with a 2kw solar array (limited to 1.6kw by cc) and 6kwh of lifepo4 with diesel geni backup. I'm finding now coming into summer that when I'm out most of the day my batteries are constantly sitting in float and I'm wasting potential solar power. I've got a...

    JK BMS Erratic current readings?

    Anyone able to offer some advice? Got the JK BMS hooked up.. all good heat shrinked ring terminal connections. Running a 3kva Victron Multiplus. In the video..never mind, can't upload, I draw 30w or so, and the current reading is all over the place jumping between 0 and 5 amps. Even the cell...

    Too close for comfort..? PV Voltage.

    Getting round to doing the final wiring on my Canadian Solar panels soon, they run at 37.7 OCV, 265W X8. I have a MorningStar 60a MPPT running a 24v lifepo4 bank. It sure would be nice to run a 4s2p setup on the panels, my problem is that comes to 150.8V. The max input of the tristar is 150v...

    Limited choices..

    I am currently building a 8s 280ah lifepo4 off grid solar battery setup, I have a Victron 3kva Multi, bmv712 and a ccgx display. For my charge controller I have a Morningstar MPPT 60a. All well and good now just down to the BMS, I've been limited to about.. two good options. I know there are...
