Oops. Had a battery on the output of this and connected Positive to negative for split second. Big spark and then smoke. One thing that surprised me is that it kept generating heat and smoking until I disconnected the 24V input. It didn't pop it's internal fuses. I was expecting more disaster...

 So Im thinking. You need a bms for charging the thing up but there aren't really any BMS that can deliver the current I would want. So I think the jumper leads should bypass the bms. Has anyone constructed one of these things? A case for an old one would work great. 4 of these little guys...

So some of these open frame Hondas have auto choke. Thus makes them super easy to turn into auto start. This one also has a 6 pin connector designed to hook into a WIRED remote control panel which also makes it easier. Modifications: 1) Interrupt starter cranking once voltage is present on 12V...

Have a bigger non-inverter generator now and want to increase charging power to shorten run times and take advantage of extra power, save fuel etc etc... I want to add an EG4 24V 35 amp charger to the 2nd a/c output of the Multiplus. This output is only active when the generator is running...

Asking this twice since it will maybe get attention here. The short. My cells discharged to 1.5 volts overnight. Generator failed. BMS failed to stop allowing discharge. Can these cells be recovered? I can make an emergency trip today, maybe with a suitcase generator otherwise not until...

So ongoing issues with this bms. The generator at the sight has failed and its winter so not enough charging. Unfortunately I cannot make it out there until Friday night. So as you can see, Discharge Mos is off but the bms shows a 70 amp charge even though no though no charging source is being...

Why do you guys use Pi, cloud services etc when you can just use a cheap PC and log into it via any remote desktop app or program and look at your stuff that way? I have a $100.00 mini pc with everything hooked into it and I just google remote desktop and I can access the pc with any android...

Posted this in the BMS forum but I think that sub doesn't get the traffic. Anyways. This was at night. There is a constant draw of 2 amps leaving the battery. The "Chargemos" shut down due to low temperature and the amps into battery reading shot up to 70 but there is obviously no charging...

It's night time. There are 2 amps leaving the battery. The charge mosfet is off. If I reset bms it reads normal until low temp shutoff kicks in and I get the reading below. It shows 70 amps in.

https://www.nbcnews.com/news/us-news/live-blog/live-updates-active-shooting-perry-high-school-rcna132235 17 year old kid. Shot himself at the end. 1) Too much internet usage 2) Probably prescribed SSRI'S. If you think the covid cover-up is bad, look at how many hands there in prescribing...

Ok. So I adjusted it to 6 then to 2 because the current readings were all over the place. Then the SOC dropped from 100% to zero. What's the fix and how do I get the thing to read current accurately?

Where can software that will work be downloaded from?

As the title stated, how do you manually toggle the built-in relays or can that even be done? 24/3000 Multiplus permanently hooked into a PC running both Victron Connect and VEConfig.

Does anybody know the hole diameters? I already took the thing out to my cabin and I'll be using some cord that's too large for the included gland nuts so I need to stop at home depot to get some clamps. I don't see it listed in the drawings in the online manual either. Thanks. If worse...

Lefties never explained and the 50 "intelligence officials" never explained what the backstory would look like if Hunter's laptop is Russian disinformation so help me out here. The Russians generated a bunch of photos, videos and emails of Hunter doing hookers, blow, crack etc and wrote tens of...

1) Microwave transformer burned up. Thought it had just suffered under voltage. 2) Noticed when I was using my shop vac, the motor speed all of a sudden drops and it makes a burning smell, then after about 20 seconds it speeds back up to normal and burning smell goes away. Thus happens...

Good Morning. I have a few little repairs/modifications to make at the cabin. A small Lincoln welder runs off my inverter generator but I would say its nothing short of abuse of here-said generator when I do. It see-saws up and down rapidly and incoherently as the current draw rapidly...

https://www.nbcnews.com/news/us-news/group-50-people-shoplift-100k-luxury-items-l-mall-used-bear-spray-guar-rcna99598 This is actually disturbing to watch.

Where is the suction level on this pump? This is in a cistern tank. The pump is protected by a pumptec. The water level got down to where it is in the photo. The pumptec makes a loud snarling noise for about 3 seconds then stops and no output from pump. should the water level even be allowed...

How do they stay so close? At no time have I ever done anything to set 100% soc on either device and the bms doesn’t talk to the multiplus.

To clarify, winter doldrums are knocking down harvest. Ill get exact numbers tommorrow, but my EPEVER will be charging at say 4.5 AMPS @ 12 volts (pitiful), battery voltage will be like 12.4. I'll fire up the generator which then powers an a/c charger which then makes the battery voltage come...

So I'll be upgrading my system in the spring to 24 volts and Victron Multiplus. Currently have an Epever 100 AMP CC and progressive dynamics RV converter handling the charging. I'll be upgrading to lithium, the multiplus and keeping the EPEVER CC. Why does or should the lithium batteries...

Bought this off ebay. It's "new unused" for $1000.00. I'm guessing the seller got it because the original dealer noticed it was damaged and got rid of it or something. Do you think this will cause any issues? Haven't fired it up yet. I guess I'll take at least one side off and see if the circuit...

Hello. When in charger only mode, do the programmable relays still activate? I want the multiplus to close the Gen start relay when the battery is low and charge it up then turn the relay back off. What is the idle draw when in charger only mode?

Open circuit voltage. ~130. 9 x 275 watt panels = 2475 watts Current total and output for the day @ 11:00 AM. Gen should fire itself up soon.

https://signaturesolar.com/eg4-lifepower4-lithium-battery-12v-400ah/ Can these be used in series to get 24V? It doesn't say you can but it also doesn't say no?

Hello. On my 12 system, I want to measure small current draws (like a few watts). This does NOT have to handle full draw but maybe a max of like 10-20 amps between the equipment I want to measure and the battery. With that said, does the victron or someone else's smart shunt catch draws that...

I access my controller through a cellular connection and remote desktop so I didn't want to tinker without asking questions. Can you download or view daily harvest data? If so, how do you do it?

Why can't these be used or can they? Battery manufacturer specifies 14.6-14.6 charging voltage and float at 13.8. I can set my MPPT solar controller to this no problem. My RV Battery charger is only used for rebulking the batteries when I am there using the cabin or when it's too cloudy to...

Hello. You're not supposed to parallel lead-acid batteries due to cell imbalance issues that can crop up. Does this hold true with lithium as well? My system is 12V. I currently have 3 8D FLA batteries in parallel. I would like to keep the rest of my equipment and change over to Lithium...

If I have a flooded lead acid battery with a 240 amp hour rating or whatever, what will the terminal voltage be after pulling 240 AMP hours out of the battery? In other words when a manufacturer is calculating AMP hours to put on the sticker, they start with a fully charged battery and place a...

A Manufacturer of FLA acid starts an Amp hour test to see what rating to give the battery. They start the test with a full charged battery and end the test when the terminal voltage reaches......?

I have a shunt installed just before my batteries. I have a small standby loaf between 40 and 60 watts and I would like to figure out exactly how much it is. Using a voltmeter and the shunt, how can I calculate the standby draw? Yes I could also use the meter itself but that's too easy. I want...
