VEConfig "Internal error occurred" when setting up assistant.

Hi All

I get the error "Internal error occurred! Please contact Victron Energy" when I am setting up an assistant in VEConfig. I am able to do firmware updates and all other settings but not the assistants. This happens whether I am using a mk3 or through VRM remote VEConfigure.

Also each time I open VEConfigurator3 it updates the assistants.

The issue started when I had updated the first inverter to 489, after the update it had to update the mk3 and VEConfig. Since then I am unable to load assistants on any inverter. Same happens with inverters on 490 and older versions as well.

I have uninstalled, redownloaded and reinstalled VE Configuration tools but still have the same issue...

Hope someone can help.

Thanks

Discharging instead of charging on dash: is my setup actually working? Or are these issues serious?

Hello,

I'm a newbie with a new installation in East Africa (Victron Multiplus 5KVa, Smart Solar 250/100, Venus Cerbo GX, 10 solar panels of 345W and one Weco 4k4 battery). It's fully off-grid.

There seems to be a few issues with the setup and I was hoping some here would know how to fix it, or let me know if there's nothing wrong. Any help would be really welcome, thanks!!

I had a professional install this but there seems to be mistakes in their setup (e.g. initially there was no power usage showing on the dashboard) and so I want to check that everything is in order.

1 - The charging lights on the 4k4 Weco battery always indicate that it's discharged, even fully charged:

[image]

2 - The Cerbo dashboard is showing the battery discharging when it's actually charging and vice-versa, like here:

[image]



3 - At night, the system (fridge mostly) takes 0.05KWh of power on average for around 11-12h. It starts discharging from 6pm (until then it's 99% full) and charging from 6am. But it looses 1kWh during the night and the battery is at 70% charge in then morning (6am) when the sun comes back. I'm guessing my math is wrong but can't make sense of this.

[image]


4 - Should the DVCC be activated (it is now)? I couldn't find out which settings should be used.

[image]


5 - Bonus question: how bad is it to discharge the battery to 30-40% on some nights? Should I get a second one? What happens if it goes to 0%?

Thanks a lot!!

Full solar Setup Advice

Hi Everyone

We're going completely offgrid due to the distance we are from power lines. I'm needing some guidance on a good offgrid setup and how to go about building it and programming it. Here's what I'm planning on using:

- Victron 48/500/70

- Victron Colour control GX

- Victron 85 amp controller

- JA Modue Solar 390W panels

- BYD 4.0kwh x4 with BMU and unit OR 4x Pylontech 3.55kwh

- Timber ground mount with flush mount system

I'm having a couple of electrician buddies coming around to give me a hand installing it all but they haven't every installed offgrid solar before.

My questions are:

1. Is installation a fairly straightforward process for your average electrician or even home handy man?

2. Is there anything I need to be aware of before we get to work?

3. Is the programming fairly straight forward?

4. Is there any issues with either of these setups or recommendations on a better setup?

5. Good bang for buck?

Thanks in advance!

My Solar panel is 180Watts (total)

Does "Nominal" 290Watts mean the controller requires a minimum of 290watt solar panels?

IP22 Boiling Batteries

Hello,


I recently installed an IP22 3 output 15 amp charger in my trailer. I am using the charger to charge three 70ah Lead Acid Deep Cycle batteries. I have attached a wiring diagram, I have the batteries and charger setup in this way as batteries two and three are also used in my caravan where they too are charged separately but used together.

When I have the charger on its standard settings for Lead Acid batteries it starts to boil the batteries during bulk charge. I have the charger now setup on custom settings to prevent this but this results in the batteries not being fully charged. The charger is set to 7.5 Amps and not 15 Amps, why would the charger boil the batteries during bulk charge? My 5 Amp CTEK charger never boiled the batteries, I'm sure a 2.5 Amp higher charge current would not cause this.

The question I never got around to asking but now remember

So I just want to know for sure how to obtain an accurate reading of the batteries from the MPPT controller in setup stage. I always go with a certain order,- first the battery to controller, then load, then inverter, then Pv. Due to my configuration however, it is a little annoying to have to dismantle the batteries or inverter, and have to reconnect in order again, and go through the whole ‘spark’ of connecting the inverter again. So it would be nice to just keep it all connected. Not sure if you know what I mean, but question is; does it really matter about the order, given that there is an he mix? -for example, if I add the inverter to batteries BEFORE I connect the MPPT, will it REALLY affect the reading of voltage from the MPPT controller?


oh please note that I have a bluetooth temperate sensor. So if that changes anything, given that it is reading from a-close to the terminals. Was told this improves accuracy of reading (makes sense) however, nothing I read explain you must put this on in a certain order…


just like to be clear on things :)

help w/Victron Energy SmartSolar MPPT 75V 15 amp

hi. i am new to solar and. hit a wrinkle that i hope is something simple/obvious i might have overlooked.

Using 2 solar panels 12v. i measured the output of ea. and was getting about 15v. I hooked them up in series and measured 30v. thought i was good.

plugged it into my Victron Energy SmartSolar MPPT 75V 15 amp controller, and measured across. the terminals and got about 12.5v. the bluetooth app showed same.

so i unplugged the solar panel measured across it again. 30v. so it seems once i plug it into the controller the pv terminals show 12.5. I measured the battery. and load terminals. got about 12v using it w/a 12v battery which for testing i did. disconnect and i had no load connected just a volt meter.

any ideas. why the controller isn't sending power to charge the battery w/30v from the solar. should be enough to activate the charge ckt, but. dunno why. i am not measuring 30v at the pv terminals when i plug it in

anyone have any ideas what i did wrong?

Victron Multiplus Compact best setup in a motorhome?

Hello everyone,

I'm installing a Multiplus Compact 12/2000/80-30 230V in my motorhome, and would like to validate my planned setup with y'all.

The Multiplus is connected to a bank of 3 parallel LiFePO4 12V 100Ah batteries, thru a 300A megafuse on the positive cable and a BMV712 shunt on the negative cable, and as soon as I finish upgrading its firmware and configuring it, will be connected "in between" my motorhome's external AC cable -- the plan is to cut the cable at the point it comes in from the street, and the part coming in will be connected to the Multiplus "AC IN", and the part going into the motorhome will be connected to the Multiplus "AC OUT".

The idea is to be able to use the Multiplus charging and automatic transfer switching capabilities).

What do you think?

Thanks in advance,

BMV712 - Amps vs Percent?!

Hi All,

I just can't figure this out and it's driving me nuts. There are similar posts but never a working solution?

I have two 6v Golf Cart batteries connected in series. 230 Ah. System settings and wiring below.


Victron reports 10.4 amps used, and says that's 97.2% of 230 amps. (is that not 95.4%?)

But when you take their 97.2% of 230, that SHOULD BE 6.44 Amps used?

HOW DOES THAT WORK?! What am I missing here?


What I've done:

- Fully charged the batteries to 100%.

- I then let them let sit for 2 days to stabilize voltages (Completely disconnected all power leads - only thing connected was the BMV 712 - just the little power wire)

- Battery read 12.8v after the two days (The little BMV power wire was still connected)

- I did as the manual states to set zero current:

A zero current calibration is (almost) never needed. Only perform this procedure in case the battery monitor shows a current while you are absolutely sure that there is no actual current flowing. The only way to be sure of this, is to physically disconnect all wires and cables connected to the side of the shunt. Do this by unscrewing the shunt bolt and remove all cables and wires form that side of the shunt. The alternative, which is switching off loads or chargers, is NOT accurate enough as it does not eliminate small standby currents.

- To me, it should not matter the state of the battery when you set Zero Current?

(There is NO current flowing as the battery is disconnected)


Can someone explain it like I'm 5? LOL

So far everything else seems to work like it should, but I'm still confused as to what my battery state really is?

Battery reports full when I believe it to be from the converter (and also the MPPT charger on the solar reports the battery to be full as well)


At the VERY LEAST, what is more accurate, the percentage, the amps used or the voltage?

(So far, I've been following Amps and watching the Voltage reading and trying to make an educated guess that way) Voltage will read 12.1v when the percent still reads in the low 70's? Is that not empty? So confused :(

To me the percentage is so far out of wack that it make ZERO sense. This battery monitor DOES NOT help me monitor my batteries :(

-----

BATTERY DETAILS:

The battery is manufactured by East Penn MFG also called (DEKA) its a GC15.

Two batteries connected in series will be 230Ah. (130Ah useable)

- Reserve Capacity at 25A is 448 Minutes

- RC at 75A is 120 minutes

- The Peukert’s coefficient for most use cases for this battery is 1.24


What is the recommended Bulk, Absorb, Float, Equalize and maintainer parameters?

- Bulk charge to 2.35 volts per cell and hold for Absorption. (14.1v for two in series)

- Float charge at 2.25 volts per cell. (13.5v for two in series)

- To compensate for battery temperature not at 20°C:

- subtract 0.005 V/cell for each 1°C above 20°C;

- add 0.005 V/cell for each 1°C under 20°C.

- An Equalization charge can be done at 15.5 volts.


Max bulk charging current is <=30A per 100 Ah (C20). So for this 230 Ah battery, that's 69 amps. (If charging a pair in series, it's still 69 amps.)

i took it back to local agent who tested it on a 24v system as they didn't have an array big enough or enough batteries to setup for 48v system

it worked perfectly

when i got it home i just changed system voltage back to 48v and there is no current flowing

so i retested it here with 110v on the PV array and system voltage at 12v and on one battery and it worked

i then retested it at 24v system voltage with 2 batteries & on same array and it worked

but doesn't work on 48V system

Configure MultiPlus Battery Setup & Charger

I have a MultiPlus system which I can't setup the charger on because of the blasted password.

Telsa Batterys have got a specific charge requierment, the paramenters I want to use are in the Multiplus are min 21.5v to start charging the batterys off landside power and shutdown of charging from landside at 23.75v, leaving the rest for the solar array to charge to full capacity.

But in Victrons wisdom you can't get access to those paramenters because they are protected by a password and if you know anything about Tesla batterys, 25.2v & above is dangerous which could lead to them exploding. Victron needs to at least release the charger parameters from behind the password so people changing out battery banks can atleast setup the correct charge parameters for the batterys.


What would also be useful is allowing the MultiPlus to know when it should use landside power vs. island power. So if you are connected to landside power (Caravan Park or House) , it will only connect once the SOC reaches say 30% instead of it's there I will use it feature. Especially if trying to avoid bills from a third party when you have a 90% SOC which you could use instead.


Isolating these features makes no sense, even more so if you move around and the landside power is always changing from Grid to Genset for instance.


I want someone at Victron to read this and understand normal people who know, really need access to those parameters so they can setup batterys, gensets & grid to run with there Multiplus.


What I really need now, is the password so I can go in & change the charger to ideal settings for my batteries also set when it should connect and charge from the grid. I have the Mk3 to USB ready to make those changes once I can get access.

MPPT 75/15 does not load my LiFePo4

Hello.
I shortly bought an MPPT 75/15, a LiFePo4 12V/100Ah and a Wattstunde 200W Solarkoffer.

I used the cables set that was delivered with my Solar Panel and I believe, they are sufficient for the job.

The battery had a voltage of 13.48V when I connected it. So I thought it was not really empty.

The VictronConnect App shows a solar input of 60-147 Watts.

I expected to see a charge voltage of 14.2V. I expected the charge voltage to be constant.

However the battery stays in bulk mode with voltage between 13.17 - 13.63 V depending on actual solar input. Battery current is up to 7.5A

I also expected the bulk mode to end after some hours, (after a harvest of near to 500Wh in the last two days), as the battery was not empty.

What am I missing?
