Pylontech modules blocking charge / discharge

I have 4 x 3000 pylontech and 4 x 3000c batteries connected together with one of the C models as master. I have noticed on the Venus GX under the Pylontech section that sometimes it indicates that only 4 batteries are online and 4 modules blocking charge / discharge. This mostly happen at night but during the day it indicates 8 modules are online. Is there a problem with my configuration?

Cerbo CX : Wrong solar power readings

Hi ,

Some background info . Starting to build my victron system slowly from the ground up.

I have 3 solar inverters :

- 1x Kostal piko 5.5 - 3 phase

- 1x Ginglong 2.9 Kwp - 1 phase

- 1x Ginglong 2.1 Kwp - 1 phase

I bought a Cerbo CX installed and 2 x ET340 and 2x ET112. To connect them I bought 4x RS385 industrial galvanic seperated converters and a powered USB HuB. The devices show up perfectly.


The readings where ok until I connected the last ET112 (Solis 2.9 Kwp) to the CerboCx.

I see my consumption on the AC Loads increasing as my power increases that comes out op my Solis 2.9 kwp inverter . As soon as I turn the solis inverter 2.9 kwp off , the readings on the AC loads are perfect .


Also for some reason we sometimes have a generator in there ? I don't have one and the readings are static . If I refresh the page sometimes and then it's gone ? UI bug ?

Please help . Any advice appreciated .

Ripple Warning On Shore Power

I am having a problem that I don’t understand. When I am plugged into shore power and use a high drew item like the microwave (12.5amps) or air conditioner I am getting a low battery, battery voltage ripple, and sometimes an overload warning from the Victron App.
It’s strange because I don’t get any warnings when high draw items without shore power, everything seems to work fine when the power is coming from the batteries through the inverter.

At first, I thought maybe the shore power source may have not been providing 30amp’s and the inverter was kicking in to make up the difference. But it is happening anywhere I plug into a 30amp service.

Below is what I have installed.

Off grid Crypto. Using as much of the battery as possible Life04?

I have a few off-grid systems I have built for my helium mines. These were built to be as light weight as possible to get into some remote locations hiking in.

This is my first time working with Solar so please excuse my lack of knowledge on any advance setting configurations.

My question is in regards to settings. I want go be able to use as much of the battery as possible when needed, like a few days of bad weather, as opposed to having the unit cut off to increase the life of the battery. I don't mind have to change batteries more often if needed. So in short how can I modify my settings to get maximum use of batter during bad weather if battery life/longevity isn't my concern?

Skylla IP44/65 Charger Storage Mode Firmware Bug

I have been observing a firmware bug in the Skylla IP44/65 chargers. This only started occurring with either the latest (1.10) or very recent firmware. Upon power-up, the charger often jumps directly into Storage mode, or cycles briefly through Bulk and into Storage. The result obviously being that the battery bank never gets charged. This is being observed on a regular basis.

As an attempted work around,I have configured setting 30 "Watch Function (start-up in storage if battery voltage > 13V)" to OFF. Though the battery voltage was not close to 13V until the charger was powered up. Initial testing shows this to have worked around the issue; we will be able to confirm over the next week as the charger goes through multiple power cycles.

We are running a pair of synchonised chargers. One is a 60A IP44 and the other a 70A IP65.

How many Trina Solar DE15M(II)'s can I connect in series with MPPT 150/35?

I already have a new MPPT 150/35 Charge Controller and six Trina Solar (Tallmax) DE15M(II) 395-420W panels. The panel Voc is listed as a range (not a single value): 48.7 to 49.7v at 395 to 420W (respectively) at Standard Test Conditions and 45.9 to 46.7v , same power output range, at Nominal Module Operating Temperature. I live at 38.5375 deg. N. lattitude (maybe 60 miles north of San Francisco, CA as the crow flies). The Victron Energy MPPT 150/35 lists Max PV Voc of 145v start-up and operating conditions, 150v absolute max. coldest conditions. It seems like I can therefore just "squeek in" connecting 3 of the DE15M(II)'s in series, and have two of those 3-element strings in parallel going into the charge controller. The battery bank is 48v (eight 12v batteries, 4 in series, two sets of those in parallel). The panel short circuit current is 10.37 to 10.76 A at STC so that seems fine either way (3 x 2 or 2 x 3). Is this correct? Would 3 strings of 2 panels in series be better, safer, ...?

Multiplus not connecting to Onans HDKBB-6880 Generator

I have a Multiplus 12 | 3000 | 120 - 50 | 230/240V , I recently purchased a Onans HDKBB-6880 diesel generator which i have just installed . the problem i am having is the Multiplus won't connect to the Generator unless I put an external load on the generator 1st.

The generator is producing 232 volts but until I introduce a load the output of the generator the Frequency on the multi meter shows as over 100hz, once the load is introduced the frequency stabilizes at 50hz.

Can the Multiplus be set to create a load on the Generator prior to full connection.

Buck Boost DC-DC converter not found by TSConfig

I purchased a Victron 100A Buck-Boost DC-DC converter. Having installed it, the LED indicators appear normal (flashing green output LED). However when I connect a Windows 10 PC to it using the USB connector, and run the TSConfig program,

When I run the TSConfig software, a window called "Setup converter connection" appears. When I select the option "Automatic search and connect" it says "searching for converter" but nothing happens.

When I select the option "Manual search and connect", it says "please select the converter COM port and connect...", but then nothing else happens. I tried unplugging the USB cable and plugging it into a different USB port, but nothing happens.

There are two links at the bottom of the window that say, "CLick this link for the latest software" and "this link for the USB driver". Clicking on the first link just confirms that I already have the latest version of TSConfig. Clicking on the second link takes me to a page for, where I downloaded and installed their "CP210x Universal Windows Driver v10.1.10", then restarted the computer.

Despite the above the TSConfig program doesn't communicate with the Buck-Boost converter.

I find this to be useful as breaking cost down to a phase level allows greater incite into usage demands.

Spannungsabfall in den Leitungen halte ich für fast ausgeschlossen. Es sind 70mm2 Kabel dran von den Batterien zur Sammelschiene mit 600A. von dort mit 2x50mm2 zum Multiplus.

Best Wifi USB for CCGX (As of August 2020)

I'm confused on the best solution for the CCGX.

The current documentation (Section 1.6.2) found here:

says that there are 4 solutions, but only shows the 2 with victron part numbers. What are the other 2 options?

Also, when I google BPP900200300, the result is a 1 antenna device, and the ASUS model has 2 antennas.

Which is better?

Has anyone experienced this weird gap and confusion of information in the documentation?

Absorption time and Lifepo4 what is the best

Hi Victron friends

Have a 180Ah Lifepo4 from CS batteries and it has a built in "active" cell balancer.

On the camper roof 1 x 140Wp on MPPT 75/10 Smart and.. 2 x 110Wp + 1 x 175Wp on MPPT100/30 Smart

Both MPPT's are set to Lifepo4 but, I read at the bottom of the battery menu that the absorption time is 2h00 and "fixed".

If I look every day in the "history" I read "absorption time = 2h00...

If I understand correctly, the Lifepo4 is kept at 14.2v for 2h00...?

So I'm looking for an answer because a Lifepo4 doesn't need "absorption time" or am I wrong?

In the meantime, I have already set that absorption time to 0, once at 10 minutes 20 and also at 30 minutes

We have a lot of consumers, Nespresso, kettle, even induction via a 2Kw inverter, so the SoC goes from 100% every evening to 70 or sometimes to 65%

I bought this Lifepo4 for the "comfort" but I also want to treat them "correctly" and then it is about the lifespan

Since 2 days I have both MPPTs set to "adaptive" absorption

"loading" the Lifepo4 cells (unnecessarily) to 14.2v for a long time by continuing to use a "fixed" absorption time does not seem to me to be conducive to the lifespan, does it?

I can also set the absorption time to 0 because I also have a Victron IP22/30 and .... I can also use it every month when I am connected to shore power

The theme of "absorption" at Lifepo4 has been mentioned so many times

And we often read differing opinions...

But, what is actually the "best" way, taking into account that we use the Lifepo4 well every day (discharged)

Thank you very much for the responses

With best regards

ESS Throttling MPPT to zero when Grid Feed In is disabled

ESS Set to Keep Batteries charged. DVCC disabled. So, I do not want to feed excess power into the grid, but I want the solar to follow the load profile during the day where possible, and only take shortfall from the grid. Batteries must stay fully charged, do not want to cycle them unless grid fails.

Problem, is that when I Disable DC MPPT feeding in, the Solar output from both MPPT's drops to zero. If I Enable Feeding in, the solar shoots up to max, and sometimes it does feed into the grid.
