HELP - Leaking starter batteries / rotten egg smell - Travelling across Africa - Stuck

Hello Community,

Hope someone can guide me :-)

We are in a professionally built expedition truck with Victron systems. Over the last two days we have been smelling rotten eggs. I started with the toilet but ended up at the starter batteries :-(

Both starter batteries are leaking (2 x 12v series).

Q1 Is it usual for both starter batteries to fail together or is this symptomatic of an external issue ( overcharging issue or something else)?

We are parked up (Corona 19) with a shore supply feeding a Pheonix Multiplus that charges our leisure batteries and starter via a Cyrix-i 12/24-120 bidirectional voltage sensitive relay. A Victron MPPT solar charger is a second charging source (added a month ago to replace a PWM unit).

About two days ago the inverter displayed a Bulk Protection alarm. And I reset it. I didn't know what this was, but the community has told me that it means the max bulk charging time of 10 hours was exceeded. I suppose this is associated with my problem.

I noticed yesterday that my MPPT was generating 17A, but the BMV indicated only a few amps charging the onboard leisure batteries and I wondered where the rest was going as I had not much load switched on. I guess it was going into the started batteries.

Q2 Can anyone through some light on what is going on? Have the batteries failed as a result of a system issue or of their own accord and just need replacing?

Many thanks in advance to responders.

David

UPDATE 1

Multiplus & MPPT have identical charge settings (bar current limit):

Vab = 28.8v

Vfl = 27.6v

Current limits are 45A and 30A respectively.

Voltage across starter battery terminals (chargers off): 24.8v

Voltage across leisure batteries (from BMV) (chargers off): 25.5v

Voltage across starter battery terminals (MP charger on): 27.6v and climbing slowly

Voltage across leisure batteries (from BMV) (MP chargers on): 27.7 and climbing slowly

Voltage MPPT 75/15 Float and absorption

Hello,
I have two 100W solar panels on my vehicle, an MPPT 75/15 with a Banner Energy Bull 12v 130 ah slow discharge lead acid battery on a motorhome.
In the MPPT 75/15 configurations, there are no voltage configurations for slow discharge lead acid batteries for absorption and float voltage.
14.4 for absorption and 13.1V for float, do you think it is correct?
We sometimes see a higher floating voltage (13.8 V), but this does not risk causing the evaporation of the electrolyte during the period of non-use?

SBP operation

Just trying to understand the remote switch operation be for installing.

This system will be load only on a small yacht. All charging will be between battery bank and SBP.

No integration with other equipment. Simple cut off to protect deep discharge.

Can the remote be use to override the cut off and force a reconnect?

IE to temporarily bypass for emergency radio transmission, operate emergency lights etc. While charging system is brought on line.

Orion Tr 12/24-15 Isolated not displaying Voltage Output in VictronConnect


Hello, the VictronConnect app on my Android does not show the voltage output when the power supply mode is on. I used version 1.03 and just today v1.05 of the latest firmware.

Rarely does the output voltage show on the app, mainly it just shows the two dash "--".

Any ideas why?

Is there a bug in the app, or an issue with my cables? 8awg from the 12v battery with a length of 6 feet to the Orion, then 10awg from the Orion to the unit being supplied with power with a length of 8 feet.

Isolation Transformer help

Hi! I bought the Isolation Transformer 3600W Auto 115/230V (SKU: ITR050362041) from a web shop in France in October 2019, brought it in Greece (Preveza) this summer, and installed it in my boat this week.

The connections are straightforward :

Input (L, N, PE) connected from the shore inlet with 6 mm2 wires (H07RNF 3G6) to handle future 110 V input;

Output (L, N, PE) to Differential Circuit Breaker (left open at the moment).

A 4 mm2 cable connects directly the transformer case to the ground common point of the boat.

The various shunts in the transformer are set in order to: 1) output 230 V; 2) connect N et PE outputs; 3) connect input and output PEs (the boat is on the dry).


Unfortunately, when I connect to shore power, only the green Led lights up, which would be normal if the input voltages was not in the proper ranges.

However, I checked that there is 227 V on the input side between L-PE and N-L, and 2 V between N-PE (same as on the shipyard post). 0V everywhere else at the output.

I addressed the problem to the retailer yesterday, but I don't know when I will get a response, and I am afraid that this response will be anyhow to send it back, which will not be very convenient for me (to say the least).

There is no Victron distributor in the Ionian area.

Is there anything I can do to identify the origin of the problem, and what can be done from this place (I won't stay here much longer than 2 weeks).

Much thanks for any help.

Scheduled charging without ESS

Hi, I just switched on my installation of 2 Multiplus 3000s and a Venus GX and am now looking at scheduling power draw from the grid. I'm in the US and have a grid tied SMA inverter in parallel with the Multiplus. Since I can't set a grid code here I can't use ESS.

I'm able to handle turning on and off AC input with modbus but couldn't find a way to disable charging without using one of the relays which I'd prefer to avoid just to keep wiring nicer. It looks like there's no way to disable charging or set the DVCC limit to 0 over modbus without ESS, is that correct? Any workarounds?

Victron Multiplus II with feed-in (while grid on) and blackout operation

Hello there!

I am trying to figure out something rather simple but can't find the answer:

* The system is a three-phase system with three Multiplus II 48/5000. There is also a Fronius Symo 8.2 connected at the AC OUT of the victrons.

* Grid is connected to the AC IN (Spanish grid).

* Victrons have a 20 kWh BYD LVS battery.

We want to allow exporting all excess energy towards the utility grid, while the grid is available.

If the grid fails, we want the system to keep running, without feeding any excess to the grid, and regulating the power output of the Fronius Symo, in order no to overcharge the batteries.

What would be the recommended settings for VE Configure/ESS? Would I need anything else like an external contactor? If the Grid code was configured to Spain, will the Victrons still work in the case of grid failure?

Thanks!

Question about the CAN IDs of the Venus GX (VGX) messages

Hello, I am using a Venus GX to communicate with an MPPT. I have connected a PCAN transceiver to the CAN 2 port of the VGX (not the VE.Can port) and I receive frames with the following CAN IDs:

0x305

0x307

0x18EAE1E1

0x18EAFFE1

0x18EEFFE1

0x19F014E1

0x1CEFE1E1

0x1CEFFFE1

I would like to know which information is within each CAN frame so a PLC can use it for analysis. Can anybody please help me to find any document which explains the information sent by this port? In the Victron's documentation I've found only the PGNs but this is not useful as I want to use the information sent by the raw CAN bus.

Is it possible to use MPPT 100/50 Solar Charge controller just like a DC-DC-Converter without MPPT?

I want to use my MPPT 100/50 1) with a bicycle powered alternator (0 to 75V and 36A, up to 1000W but 100W normal power) at the input and 2) different electrical consumers or battery charging at the output. Actually I need a DC-DC converter with very wide input voltage range.
1) This seems to work fine (with battery at the output) but the MPPT should be switched off to get this working like a normal DC-DC-converter. Otherwise, the MPPT will never find the right point because the input voltage changes to fast. Can I switch MPPT off somehow via VE.direct settings or custom firmware?
2) I didn't try that yet because I fear to destroy the device. Is it possible to directly connect different consumers (e.g. DC-AC inverter, 12V Car Mobile Charger, Car Hifi)?

Phoenix inverters no parallel connection

I have had 3 phoenix 24/3000 inverters working in parallel for years, after a firmware upgrade on my color controller, a week later they have failed to parallel connect now coming up with a firmware issue. Was advised to update the inverter firmware. Using the MK3 interface i have done one successfully which is the newest. 2612154.HEX to version 476.

The other 2 are older 1912137.HEX and 1912112.HEX The 137 unit appeared to update but will not accept changes on the dip switch settings now, the oldest one came up with no MK2 found.

So now no parallel operation what so ever.

Network Total Power field is way off. Worked correctly the other day.

Right now my three controllers power is adding up to about 700 watts if you view them individually. But the new network power field is very wrong today. I verified all three are networked with green checks. You can see in this screen shot that one panel is putting out 242 watts, but the network field is showing 64 watts total. One of my controllers was showing 64 watts, but the third was over 300w at the time. Total should have been close to 600 watts.

Wiring help for Victron Orion TR Smart 12 12 30 in motorhome

Greetings,

I am switching over from lead battery in my motorhome and installing a lithium battery. I am attempting to install the Orion-TR Smart DC-DC Charger so the vehicle alternator charges the battery while driving.

  • The Victron doesn’t seem to work properly grounded to the chassis as in the factory configuration. It appears I need to run the ground to the battery post directly?

  • If I ground the lithium battery directly to the Victron instead of the chassis ground is it okay to also keep the ground from the battery for the chassis since the Power Converter needs that ground?

  • Because of the Buss Bar, will it cause “crossing” of the 12. 5 AMPS coming off the alternator mixing with the 14.4 the Victron Orion?

  • The Victron won’t power on unless I have Remote Wire Bridge attached, which the instructions say not to attached until you get the Bluetooth set up, which won’t connect.

What is / Can we tune BatteryLife cutoff (SmartMPPT 75/15)

I am using a pre-used 65Ah car starter battery on a tiny trailer camper. It will eventually need replacing, but I am hoping to squeeze two more years out of it. It's only feeding LED lights and phone/tablets (oh, and the potable water pump)

The MPPT is set to BatteryLife. To preserve the battery I would like to go even less deep into the battery. So while I know the BatteryLife modifies the cutoff based on whether it has seen Float that day, what is the actual base cutoff, and can it be uplifted a bit.

While I am assuming it is one of the common numbers of 10.6v or 11.1v, I feel to be safe 11.6 is a good number too. I can set that by disabling BatteryLife, but I trust the Victron engineers knew what they were doing when they game up with that adaptive cutoff. I would just like to tune the latter to "extra-safe-BatteryLife" or "conservative Battery-Life"

Grounding chassis vs AC-IN and AC-OUT

I'm finishing up a fixed install of two Multiplus 24/3000 in a split phase setup and wanted to make sure I understood how grounding is handled.

In Wiring Unlimited for a fixed install looks like the Multiplus chassis ground connects to a bus bar (in my case Lynx distributor) along with the battery negative terminal which is bonded to the ground rod for our house. Using a multimeter it looks like all ground points are connected. Is there a difference between grounding through the chassis ground point vs AC-IN and AC-OUT and if not is OK to use only the chassis ground?


Thanks!

CCGX Not showing PV Production

We have a customer with the following installed:
1 x Victron MultiPlus II (48/3000/35-50-230V)

2 x Fronius 3kW Primos (1 on the input, one on the output)

7kWh of BYD batteries


Currently everything is working ok, except there is no pv production being recorded and displayed by any of the Victron devices.

Using the Remote Console I can see that the MultiPlus is aware of both of the inverters. The customer has a Solar.Web monitoring setup for the Fronius inverters, but can only monitor one of them, so the customer can't use Solar.Web to record production data.


All of the devices are connected to the customers wi-fi, though it is not the best signal strength at the inverters.

The customer used to have the PV Production showing on the CCGX, and in the past a reboot through the CCGX would get it to find the Fronius', though this isn't working anymore.

I have had the customer run through a full shutdown of the system and restart, but this hasn't changed anything either.

There hasn't been a firmware update installed since the customer had the ability to measure

Any help would be greatly appreciated.
