Tasemu

true rms multimeter, also confirmed in the victron-connect diagnostics which matches the voltage to the reading on the multimeter.

Hi, long time since i've posted here. I have a problem i'm hoping someone can advise me on. I recently purchased a new Victron Multiplus 12/1600/70. I have run into an issue where the unit is not activating charge mode when I run my Beta Genset (BZ482). After much troubleshooting I have found that the genset outputs a voltage hovering around 260v-270v, which is too high for the multiplus to accept. I was hoping someone on here may know a way to adjust the output voltage on the genset so I am able to charge my batteries? Thanks in advance for any and all advice.

Hi all, sorry for the very late response. So my fridge started up again for some reason and has been working fine since. I'm confused as to what the issue may have been. I've turned it off for winter now. Thanks for all the advice, wish I could have worked out what the cause was before it fixed... itself? haha

To be fair i shouldn't have said 13 because that was when the battery was 13. Basically i'm noticing very little to no voltage drop from the battery to the fridge. The cable size is 10mm2 but then drops to a smaller gauge with an inline blade fuse right before the fridge unit. I'll have a look at currents and report back, thanks!

I see what you mean now. In that case it seems like something that can't really be avoided..? I've never had this problem until recently though. Lifepo4 bank is at 14.2 volts. If the current pull from the fridge starting is enough to cause this issue, I would imagine it happening fairly regularly for the lifespan of the fridge. Unless i'm missing something.

I've checked over the connection and it is solid, the battery is definitely not under charged... However after pulling out the fridge I could easily imagine that the spade terminals on the back of the unit itself are in dire need of a good clean up... Good thinking mate, i'll get that done and keep an eye out for the error code in the near future.

The 13v is pretty stable as its coming from a reasonably sized lifepo4 bank. I'll keep an eye out for codes, I saw it beeping red once a second for a while before it died. Unofrtunately there are no brand markings on the damn thing so I haven't been able to find a list of appropriate error codes. @Bod

Hi, i'm hoping to get some advice on here regarding my 12v compressor fridge. The fridge packed up and died a few days ago. Its getting 13v happily from the batteries to the back of the fridge. About 10 minutes ago out of nowhere the fridge turned on and started working again. I have no rhyme or reason why, but I bet it hasn't magically fixed itself. Is there anything I can do to troubleshoot it and see if maybe its salvageable? The prices for a new fridge is incredibly expensive. Thanks in advance for any and all advice!

I have a Rayburn 212 and it works a treat. Imagine it must be a nightmare to install though.

480ah, usually takes 2-3 hours to put the batteries into float. I also use the genset to heat water at the same time via an immersion heater. Also for cooking in summer via induction hobs. Sounds like a victron inverter-charger might be a good move, but will also require rewiring everything I think, for the larger amps. PS: Genset is fixed and working great now, was a busted impeller and anti-siphon valve. Now i finally can see what it looks like working properly.

Excellent, yup i got a 20a sterling

Haha fair point

Currently I don't use 240v between 8pm and 8am. Just looking to see if i should be putting in 12v sockets or if an inverter will do the job fine and not lose me too much power in conversion. Everyone always says use 12v wherever possible, so that's stuck with me.

Its definitely spitting water out the exhaust, but water vapour too. Not very much of it tbh, just a little. I've checked everything except the impeller, gonna leave that to the guy. Everything looks good, except that the water level in the water strainer/filter seems a little low. If I put my finger over the anti-siphon valve for a second, it fills back up though lol... What am I like haha. Save me from myself..

You know what! I got down by the exhaust and had a big whif of it, its definitely water vapour! No idea if that's bad or not, but i've clean LITERALLY everything else and i have no idea. Got a guy coming tomorrow to take a look at it, and another to look at my rayburn. Bring Out Another Thousand is starting to make sense to me now. EDIT: Or it could just be the fumes

I think I have found my answer then. I'll see how the 10w standby current goes for me. Thanks for all the help.

Ah, that's not bad. They never specified the spec on the website so I thought it was more. I think I may be min-maxing a bit. The victron is 0.9 watts.. somehow that feels pretty sweet to me. I reckon i'll take your advice and plug in my 1.5kw. Worst case i can just swap it over. Do the big ones chew more power when converting?

Just read this, on second thought I'll be able to charge the phones off the 12v socket anyway. Got a dual usb adapter running from there, so it'l just be the 2 laptops and maybe some misc stuff. I already have an inverter from sunshine, i just got a new new boat and want the best tool for the job! Not sure if that's pointless or not, but that's what i'm here to find out.

i have a 1.5kw inverter already from sunshine solar but I feel like it pulls a lot of passive power and has no load sensing. Was considering a smaller victron phoenix... 0.9w in passive mode. edit: not installed btw

Sorry, should have stated that, phones, macbook pro (x2). That's it I think. Anything heavier will be powered by the genset instead.

Hi all, I have my new boat and its 68ft long. My boat has plenty of 240v sockets throughout the boat but only a single 12v cigarette lighter socket in the saloon. The 240v is powered a diesel genset but no inverter is installed on the boat. I was wondering if it is a good idea to buy a small inverter with a low power consumption, rather than taking the time and money to install a bunch of new runs/fuses for 12v sockets throughout the boat. I know inverters have a power loss, but am hoping that a small inverter (with some kind of load sensing) could be a viable alternative. If an inverter is a good option, does anyone have recommendations for a model? Ideally with load sensing. Thanks as always for any and all advice!

Anti-siphon valve all cleaned up but i couldn't spot any blockage or anything in the pipes or the valve, it did have a little rubber thing in it that is what i'm guessing is knackered and making it squeak. I've also noticed that there was very little water filling the strainer bowl when running. I put my finger on the anti-siphon valve for a second when it was running and now the bowl is about half full and looks to be pumping happier. I think i've been overheating the genny lately and maybe this is why? Is there an issue where a broken valve could cause the pump to pull more air than water and raise the temp? The genny still puts water out the exhaust either way though... I'm confused haha.

I think that is exactly what it is yeah

Good point sorry! I'll add a picture once my phone charges. Its a beta BZ 482 with raw water cooling. Installed in the engine bay. There appears to be a separate weed hatch for it, which then pipes to a secondary filter, then to this valve or nozzle (looks like an upside down plastic drip tip) and then into the genny. It could be the only filter, i just heard it called that by another boater. Pics incoming shortly!

I'm getting quite a lot of noise from behind my genset, there appears to be some kind of nozzle at a high point in the piping after the secondary filter. It appears to be to let air out of the pipe. It is making quite a racket but I don't think its steam or anything. I'm slightly worried though and was hoping someone may be able to inform me why its doing that. Cheers for any help!
