I wrote 14.2v in the post simply because I can't remember what the figure is supposed to be. Below are the Victron IP65 charger voltage settings I use when balancing. There's no debate here- that's what BB recommends. When using the Victron Connect App I wait for the batteries to conclude...

"The Victron balancer is intended to get the results you desire." Ok. Perfect.

Oh....well....here's the video- https://www.currentconnected.com/product/victron-battery-balancer/

Tim...didn't you make a video about that? I watched it. Thanks. As before I'm really tired of having to balance the batteries once per month. The entire system has to be shut down, the AC lines from the M+ placed into grid outlets (not fed from the M+) and then balance each battery. Tired...

The Victron balancer is only $56.

Correct, I do it because BB told me to do so.

I have 2 BattleBorn LifePo batteries in series for a 24v off grid system. Once per month I balance the batteries individually. That means charging each battery up to 14.2 volts using the Victron IP65 charger. (Pretty sure that's the voltage). Well, I'm getting tired of doing it...

Yes, that was understood. The foil pieces on the connectors are only about 2 inches long and are two horizontal feet away from the batteries. So long as I don't move the Rsp and USB cables around to relocate them all is well... so far. You're probably right- I'll end up buying two more...

Well, no, I can't. The array is in a fixed position. Frankly, I'm glad I'm having this problem as I had anticipated purchasing another 2kW of panels. Will just leave things as they are and get 8 awg wires until I get frustrated by the reduced output on cloudy days.

3S doesn't exceed the MPPT. Only once in the past 2 years has the 2S reach 79 volts. The MPPT is rated up to 150v. 3S would give 120 volts and that's safe for my 150v 60A MPPT. But....I had have to buy a 2 more panels (which would be a total of 12 in the array) or reduce the size down, as...

You're probably right. They were noticeably warm...not hot....just warmer than was to my liking. Also, I've got to put a fan on the MPPT to cool it a bit. Gentlemen, at my age I have little tolerance for "risk". (That's why I'm not gambling in the stock market).

'Had considered that as well but the 8 awg is a better option. I have 2 extra panels so the system would be 2S-5P for a possible 2.5kW (9 amps per string). But, I think the Victron 150/60 limits the input to the MPPT to something like 1700 watts. I'm not sure about that.

Will do. Thanks.

Ok....thanks. Nuts....now I'll have to fish the new wires. Better safe than sorry. In the mean time I'm going to isolate two of the panels....or pray for cloudy days. The major power production was caused by recharging to the LiFePo4 batteries and not the loads.

The run is about 30 feet. So, the question is- what size wire to should it be increased to? 8 awg?

Of course I did. However, today I cut down some trees that consistently blocked the array so the increased power resulted. Also, I'm referring to the wires FROM the combiner box to the MPPT. The wires between panels are fine and produce around 7 amps

Today my panels produced a consistent 1600 watts. The array is 2S-4P (250 watt panels 40 volts for a 24 volt battery system) The amperage from the Combiner box to the MPPT (Victron 150/60) was around 30 amps and the Cerbo/VRM showed a peak of 33 amps. I checked the wires from the combiner to...

No pictures. Too lazy. Just sloppily wrap some aluminum foil around the first couple of inches of the USB portion of the connector- that's where the fancy electronics are located or somethin' like that. As to "Tin foil hatters".....I used to laugh at that notion. Now, with the wretched...

Trees? I'll email you some....

I've been using a Rsp Pi with Venus to watch solar output on VRM. In the past, unpredictably, either the MPPT or BMV signals would be lost and I'd have to reboot the Cerbo/Rsp. The problem has been often attributed to cheap Amazon, non-Victron, USB direct cables. I wrapped a piece of aluminum...

This is supposed to be funny. I've found a simple way to double the PV daily yield of my array which is 2 kW. Usually, the array only produces 2 kWh per day. Today, a bright sunny one, produced 4.1 kWh after the minor improvements which I describe below. The following method is thoroughly...

The result; Today I configured the Multi for "Prioritize other energy sources" It does exactly what I wanted- stops charging the batteries when set to "On" in VRM. 'Was very much worried of blowing the Multi and myself to smithereans by changing the settings using VE Configure. Man, I wish...

That's what I'm now planning on. 2kW was fine for a start and got great experience in the process. More power.

My thinking is that you're closer to understanding what I want to do. Now, I'm running the Rsp Pi and fiddled a bit with the Generator start and stop function but was too scared to try it for fear of seeing smoke pour from the Multi. In truth, I've been watching VRM-ALL-DAY-LONG every few...

I think I'm senile. No. The idea is to get the multi to not charge the battery to full once switched to "On" in VRM (that's a specific option in the Dashboard at near the top right of the VRM screen). Once the Multi goes in to Bulk the grid power really gets dumped into the batteries and I...

I wouldn't let it go dead. (I hope). I want the sun to do all the work in providing (most of) the electricity. Charging the batteries with grid accomplishes nothing in energy saving, as I mentioned before, if the PV provides 2 kw during the day but I have to recharging of the batteries to...

When the batteries are low, in terms of SOC, I click the Multi's "On" box in the VRM and the Multi immediately starts charging the batteries and load with full grid power. During the day that's fine when I'm inclined to bring them to full charge. However, it would be nice to have AC pass-thru...

Honestly, I think I'm asking the wrong questions. This is so darn confusing.

Adam, in one of your videos you mentioned turning the charger off. I think it's the first video above. Where's that option located...in Assistants or Virtual switch options?

My Rsp version, Venus os, is 3.11 and multiplus is 506.

In my configuration whenever I use the Cerbo (Rsp Pi) I switch the Multi from "Inverting" to "On". Once it has been set to the option "On" it immediately starts charging the batteries and supplying AC to the loads. That's not what I want to do. I don't want the Multi to charge the batteries...

I've got a Multiplus 24 2000 and it works very well. The problem I'm having is I lose all of the solar generated energy at the end of the day (let's say 2 kW) after switching from "Inverter" to "On". "On" will fully charge the battery and supply AC loads simultaneously. That's fine but I'm...

The OTG adapter arrived and it worked a few times in connecting to VC but then was entirely unpredictable and more or less useless. So far, after working with the stupid thing for about 1 hour with my phone, I've given up. I guess you should expect that considering I paid $2.59 from ebay.

I'll let you know what happens.

Yes, me too. I could be the USB C cable I'm using is just a charging cable with no data ability. I'm just guessing about that.
