This may be the answer: https://shaneyake.blogspot.com/2022/09/victron-disconnect-inverter-from-grid.html I was/am hesitant to just short the Aux wires together, but it looks like that is the way to do it.

Hi Eggo, I think assistants will be the way to go eventually – after I have a better understanding of them. My use case is as follows: Primarily critical system backup. I am in a rural area at the end of a line. Anything that happens affects us, and with the low population, we are low...

How many reprograms is too many? Using the VE Configure software, are these settings being written to a flash memory that will degrade over time? Specifically, Is having multiple configurations for different weather conditions with frequent changes going to be bad long term?

I'm glad you posted this. I had no idea thermal scopes could focus down to distance practical for electrical inspection. However, they do! The zoom is a little annoying, and there is no estimated temperature reading, but it works incredibly well. I mounted mine on a tripod to make the...

You need VOC not VMP

I have a Signature Solar 5000 ES powering a single mini-split and charging a battery bank that has been in service since early summer. A recent new development is that it requires a complete shutdown (removal of AC, solar, and battery connections) to re-train the MPPT. The MPPT gets stupid...

Probably because it seems many actually can't

What brand/model did you get? I have the same thing.

That pole barn looks exactly like a project I have in mind. Could I talk you into taking some more details and photos of that?

Which are "these" ? The 450V Victron?

If you are open to pre-built and/or server rack batteries, I would buy SOK from Current Connected without hesitation. Ian from watts247.com also has them, and had a sale going. Ian has a good reputation here. Since you are running on a generator, I might call both to see which one would...

Mine has been great for about 3 yrs so far. Should I buy a lotto ticket, or did I use all my luck on the water heater?

If they are actually balanced then I think you've been lucky, and I am not sure how much longer your luck will last with that. Keep in mind that in the 40%-80% range, you are in the REALLY flat part of the voltage curve, and the cells can be considerably out of balance with very little...

It's situational - the only advantage of the bottom balance that I know of is that it is easier to add power than to get rid of it. The charger I used sends 6 amps to the cell, I don't remember the dissipation for the Jakiper BMS, but I think it was 0.6 amp. Having said that, if you have one...

It is a "Lv yuan lian" charger. 110 plug on one side, small pos/neg alligator clips on the other. Model#: H10980150W Input: 110V-220V 50-60 Hz Output: 3.65V/6A I've never seen or heard of it before. I do not seem to have died or exploded anything from my limited use of it, but it isn't...

Test on discharge to see if one of the same runners becomes the first to nosedive. If so you likely have a bad cell. Mine actually turned out to be a bad cell, and Jakiper sent me a replacement along with an individual cell charger to match the new to old state of charge. Something to keep in...

The easiest way for him to determine this is to get more than one quote.

What were the other quotes?

"voltages between 3.3 and 3.37V" I went through this too. The thing I had to learn coming from lead acid batteries, is that relatively minor differences in voltage - particularly in the range you have described - can mean that the cells are in very different states of charge. If you are...

Answers to questions like this are incredibly location and company specific.

This will be ignored, while wild speculation will continue.

It's balancing away now. You were absolutely correct. Closer study found that one cell would trigger the over voltage protection even at conservative overall charge voltages, so the extreme settings were needed to slowly reach the BMS balancing voltage without overwhelming it. I think my...

There was a large spread at peak voltage. 3364Mv to 3515Mv. I have set the absorption and float as suggested and will update after a couple of weeks if I can remember to do so.

Thank you again for your help.

Thank you for your help. I will get them fully charged and look at the voltages. The Multiplus is currently set to Victron defaults - 56.8V absorption, 54.0V float and 1 hour absorption time every 7 days. Assuming they are different, do you have suggestions for absorption/float voltage and...

It has recorded over-voltage protection, but they all have. I thought that was from balancing? I have looked but not noticed an extreme voltage when nearing the top of the charge. Chargers include a Victron MultiPlus set for LiFePo4 batteries and the signature Solar charger. I THINK I saw...

One of my Jakiper batteries now indicates 93.0 amp hours instead of 102.9 on the LCD display. I have not checked any further than this. Did I really lose ~10 amp hours - or do I need to do a reset, or something else? There are 10 cycle on the battery at this point.

Will there be a 25 Amp version to swap in any sort of reasonable time frame? I'd rather you keep the money and get what I ordered vs return the one I have and start shopping again.

Did you find anything out?

Any Updates?

Hi Richard, I received an email offering a partial refund or return, stating 25A units are not available. Are the 25A units gone forever, or will there be a 25A unit available later? I'd rather wait if possible, instead of a partial refund or a return to re-start the shopping process - I...

Just send a really big current through it.......

I do appreciate what you are doing, and understand that you have more to do than post here. Can we see some uses with the grid passing through? I'd really like to see PV and grid and the effect they have on the loads. If you will show us 120 loads with PV and grid input with no current trying...

The ones on Amazon that look exactly the same are rated at 20 amps max. Mine from SS has produced 17-18 amps maximum on a 50% battery with nothing else connected.

I can't take the JuncTek seriously after saying the name out-loud...
