Hi,

Two question regarding the Sonnenschein @home lithium

1. Will become an approved Victron battery?
2. If used with the Color Control GX will it be able to have managed DC coupling like the BYD and Pylontech?

We're connecting two 24 volt Tesla batteries to 2 LG panels to have some off-grid power. Do we need a BP 220 for each battery or will one do for both?

The fan may run for 1-2 hrs. Other times it cuts in runs for a period cut out and then cuts in again after a few mins. The unit is not hot. The circulating air is cool. Any thoughts? Is it a heat sensor problem?

I just installed a new ccgx at one of my customers' site. I registered the new unit on VRM and followed the procedure to change the old ccgx with the new one. The following popup appears

It requests an input before the button "confirm". Which input is requested? Thanks.

I received this video from a client, but struggling to identify the LED error codes. Seems to be 2 different codes:

In both cases the Inverter On LED is FLASHING, alternatively tot he Bulk, Absorption & Float LED's which means it is VE.Bus error.

1) Float LED on with Bulk flashing = code 13.

Can't find interpretation of code 13 anywhere.

2) Float & Bulk flashing = code 14.

Error 14 - Device cannot transmit data

Most probably a short circuit in the communication cables.

Another possibility, very rare though, is a broken component on the board. Return the device to

the nearest service point for repair.

System does not have any comms cable, no GX, no BMV. Just Multiplus and MPPT, with batteries and panels. Grid-connected, but running in off-grid mode.

Can anybody please interpret the error codes for me, if I have it wrong? And then also let me know what code 13 means?

Thank you,

Anita

I have a Bmv and twin 150/35 controllers

Chargers will go into float each day but the bmv reading drops by ave 2% each day

Ive done a reset to 100% Next day 98% so and so on

Checked shunt Think that's ok

Any help

Hi together,

I have a question concerning using a BatteryProtect (BP) to disconnect the charge source in a Lithium Battery System with VE.bus bms.

In the BP manual Figure 5 illustrates how to connect the BP for charging situation and it states that "uncontrolled reverse current will flow through a Battery Protect if Vout > Vin."

Now I wonder what happens, when the Voltage of the charger (Vin) drops, i.e. Solar charger when there is no sun or any other charging source that is swithched of. Wouldn't then the Voltage of the Battery (Vout) be higher and thus reverse current flow causing danger?

THanks a lot for your comments, I am abit affraid of burning down my RV...

cheers, Daniel

I am intending to buy a Multiplus II 3000VA GX.

With my 10 kWp installed Solar power and a 9 kW inverter, I will not meet the factor 1.0 requirement for AC coupling.

Can I still use a Multiplus II for ESS , even if it is not AC coupled ?

Can I connect the Multiplus grid-parallel in this case ?

What happens in case of grid-failure if connected grid-parallel ?

Can the Multiplus power the connected house phase in case of grid failure from the batteries then ?

Thanks much for your help.

Daniel

Newcomer here.

Here is what I have:

1. 30' trailer that is "pre-wired" for solar. 10ga wire running from roof connection to closet about 15 foot wire run. 8ga wire from closet to battery bay also about 15 foot wire run.

2. Running 2 Zamp 170 watt panels in parallel.

3. Have Victron BlueSmart MPPT 110/30 controller

4. Have Victron BMV-712 with temp sensor.

Question: Which is better:

A. Do I place the controller in the closet and connect to the 8ga to the battery side and the 10ga to the PV side? Use the VE Network to provide battery temp and voltage to the controller.

or

B. Do I splice together the 8ga and the 10 ga, and then place the controller in the battery bay and run short 6ga wire to the battery from the controller.

The issue I am trying to avoid is voltage drop from the panels if I place the controller in the battery bay.

Thanks,

Bill

Hi all,

Just confirming here that when my boat is floating on the water there should be a link from the input PE terminal to J34a.

So, the earth wire from the shore power supply flex is connected to the input PE terminal and I make a small wire up with a female spade connector from this input PE terminal and connect it to J34a?

This transformer is not the auto 115v - 230v switching model

Many thanks

Hi

I am installing a system using Multiplus charger/inverter. I need to configure the Multi. Hence communication between PC (Lenovo Win10) and Multi is required.

I have installed the VE configure III and I have a MK3 USB interface.

When I let the VE Config auto detect nothing happens i.e. the programme is doing a search and eventually times out.

When I try manual connection to e.g. Com3 an error message apperas saying "Cannot open Com3" - it does not help to change Com port no.

I have removed and re-installed the MK3 driver. In device manager I am able to locate the virtual serial port i.e. that part seems to work fine.

I have also tried to use the VE Bus Quick Configure software - and the error is the same

Any good suggestions?

p.s. I have tried on a different Multi and the error message is still the same. I have not tried a different PC yet - not so easy due to remote location

I have just had a new Solar PV system installed. It uses a Victron Multiplus 24/5000 Inverter/Charger and a BMV712. I want to buy a Venus GX. Can someone tell me if all the cables etc. necessary to connect the system together are supplied with the Venus

We have a Lister-Petters TR3 with Stanford 16.6kW generator charging a 24v 1150ah AGM bank with a Multiplus 24/5000. At max charge (120amp) and daily load demand, we have difficulty achieving a constant high SOC. Could we utilise the genny better by having an additional 120 amp charger in conjunction with the Multiplus 24/5000? The +/- leads from Multiplus to bank are 100mm2 x around 4 meters long. Thanks, joe

Today I tried to connect to my system and VictronConnect could not see any of my devices. The iPhone Bluetooth settings showed the devices, but VictronConnect device list showed 'No Device Found'. I noticed the VictronConnect version had been updated to 5.13 just the night before. How do I reset my devices, VictronConnect, and iPhone so as to start with a clean slate?

load indication on ccgx/venus in ess mode

it is not entirely clear how the loads are divided between AC loads and critical loads during ess mode.
in my case all loads are either on ac2 or ac1 output . which load is considered a critical load and which one is AC load

Is the critical load equivalent to what inverter is feeding?

and the remaining loads are termed AC loads which basically equal to Input from the grid - (PV inverter - Critical loads) ?

In a related question is there any way to separate thge loads on AC Out 1 and AC Out 2 in VRM .

In energymeter menu there is no possibility of selecting the location on the output side ?. I would be glad to put a separate EM340 on the load side and log it to VRM

[image]

Hi

How can I display the critical loads and ac loads like in the pic below (pic from another user question)

I have Multi 24:3000 don’t have ess installed yet

I can not select grid code AUS/NZ grid code and have lom device,how can I select au/nz grid code or do I have to select other not complaint

Thanks

Hi

I have just moved into a Marina and I need a little advice. We have shoreline power going via 13 amp socket into the Multiplus inverter, which is a Phoenix Compact Multiplus 12/1600/70. This then runs out to a consumer unit for AC.

Do I still need a galvanic isolater or will the inverter do this for me? If I do need one where does it need to be fitted? between the consumer unit and the inverter or between the 13amp socket and the inverter?

Any help much appreciated

Thanks

Matt

I plan to add further supplier sources to my of grid System: 3x Quattro 48V-8000VA with Pylontech Batteries 40kWh behind. For continuous feed I would like to integrate a SkyWind Micro - Wind mill 1kWmax connected to the 52Hz off grid environment.

The FuSystems SkyWind is able to drop the AC power if no loads are connected.

The power is provided by a 60Hz AC connection in the micro grid while dumping the power into a heat sink when no loads are connected. In between a 60V DC to AC conversion is done.

Question: Does the Quattro AC output provides an adequate (grid like) stable frequency and 1-phase voltage to the SkyWind AC-Converter/Controler (needed to simulate an on-grid / without feed-in situation)?

Is the Quattro’s AC frequency strong enough, concerning the consumer sided behaviour based on active loads or no power consumption situation to indicate the heat sink or AC power provisioning ?

Does the Quattro provide preventions to consume itself the AC power on the micro grid side?

It seems a simlar control as been established with “Fronius PV Inverters” on the AC consumption/ micro grid side, which in fact has to be configured in a special setup.

Hi Victron community

I was wondering if the neutrals in the Easy Solar 3kva ports input ( generator ) AC1 output via rcd or cb are connected when the generator input is running .

I have disconnected the men at the generator and the relay men function in the Easy solar . I am back feeding the main switchboard form the AC1 out put and men it there ?

my question is now should I have run a separate earth back from the MSB to the generator to men the generator ? or should I have left the men in place in the generator ? the inspection company is getting me for AS/NZS 3000 7.3.2

Can anyone tell me where I can find the pcb schematic of a phoenix Inverter? There are no suppliers in my country (Angola) and the person who installed the Inverter is no longer reachable.

I just updated my 12v 400Ah lithium battery system, reusing many components including my BP100 -- the BP100 worked previously but now is giving me an E1 (short circuit) code when I connect the battery positive to it. I have done a lot of testing and don't believe I have actually have a short circuit. Can you tell me what reasons would lead to the E1 fault so I can rule them out? Or is there a way to test if the BP100 is definitely faulty?

Scenario 1: If I remove the "out" load cable from the BP100 and connect the battery to the "in" the BP100 will not give an error.

Scenario 2: If I have the load cable connected to the "out" and turn on the battery, the BP100 will give the E1 error and not provide power to the "out" post, however if I use a jumper wire with a 15A fuse in line and touch it to both the "in" and "out" posts on the BP100, it will provide power to my house, not blow the 15A fuse, and I can also remove the jumper cable and the BP100 will work as normal, continuing to provide power to the "out" post without any error codes.

Hi folks,

I have a 5kVA Multiplus, wrapped up in an easy solar package but I dont think that matters in this context.

It is hooked up to a 13.8kWh BYD pack, all installed as it should be.

I am looking for opinions about doing a limited amount of welding, using a modern inverter based welder.

The welder would only require a single 13A supply and would probably only need to be set at about 80%, possibly less, of its maximum output.

Obviously load isnt an issue, but I am interested to know if I should be considering anything else or even if there is some technical reason that some load are not advised.

Thanks,

Al

I have a Multiplus 12|3000|120 installed to primarily run a hoover auto washing machine. The washing machine is 50Hz 220-240 Volts. Checked inverter settings with Dip switches. When running washing machine with Genny no issues, with Inverter the control panel lights and counts down the minutes but nothing operates within the washing machine. Tried running with a 100w lightbulb as suggested on this forum, no difference, no noticeable flickering of the light bulb. Has anyone found a solution to this? Or have I just wasted a rather large amount of money. Thanks

Handcarried this inverter to Philippines for my solar plant (24V, 200Ah lead-acid battery, min 25.2V max 28V, PWM controller, new battery, 50mm2 cables 1.5 meter). Worked brilliantly for 2 weeks at 60Hz, 230V. There was no internet connection.
2 days ago, there was an internet connection and the software updated automatically, no problem. The unit powered an inverter washing machine @ 650W max.
The inverter gets shutdown for the night. Next morning, the red/green lights started blinking alternately in 1 second tact. No output. The input voltage is min 25.2V and max 28V (measured with a Fluke at the inverter connections.
I cannot take the inverter to the dealer, a bit too far. Can somebody please give an indication what the blinking lights might mean and how to correct it? Thank you!

I tried to describe my problem in a file with drawn diagrams of my system. Please see the attachment.

Hello.

I'm trying to workout best way to wire up my panels I have a victron 150v 100a mppt Controller, my panel have a maximum voltage rating of 30.5v.

So sould my strings of panels strings in series be made up of 4 or 5 panels.

My system is 48v

I'm guessing that as my panels are used I could get away with 5.

4 panels 122v

5 panels 152.5v

Solar Panel Watts 255

Maximum Power Voltage - Vmpp(V)30.5

Maximum Power Current - Impp(A)8.37

Open Circuit Voltage - Voc(V)38.1

Short Circuit Current - Isc (A)8.83

Panel Efficiency (%)15.67

Height (mm)1640

Width (mm)992

Thickness (mm)40

Weight (KG)18.5

Cell TypePoly

I can't find the Discharge Current Limit shown anywhere for the 14kW battery bank. I have GX version 2.33 firmware and two batteries (28kW).

Please can someone advise what this should show and if possible where this is shown on a Victron web page?

Thanks.

How can I recover? Trying to leave app results in the message "Firmware update in progress, don't leave the current page or close the app during the process.". I have a smartsolar 100/20. upgrading to 1.46 from 1.39. Green/Yellow light alternating quickly.

Hi all, After a session of changing some settings using VE Configure over MK3-USB and simultaneously having a remote LAN CCGX connection open and also sporadically making changes using ModbusTCP, my CCGX remote display started reporting my Quattro was 'Off' (which it wasn't since the inverter output was happily powering a load). In the menus of the CCGX, the Quattro was described as 'Blocked'. I solved it by physically switching the Quattro off then on again. I guess this was because I had been changing some stuff over an MK3-USB link/ModbusTCP and something became confused by too many changes close together or having too many connections open. It has only happened once and clearly I caused it somehow so I am not too worried by it but it would be interesting to know if there is any way to prevent it happening again. Can anyone shed light on what could have caused this? Many thanks, Dave
