solar

GX GSM is not on my settings list , so can't get GSM too culminate with Easysolar 48/5000/70. Have checked SIM in another phone and can call and receive calls on an old phone in exact location of GSM Aerial ? Can someone please help . It is an optus SIM in Australia

In smartsolar datasheet it is written :

maximum battery current = 20 A

doest it mean that current to charge batteries will be properly limited to 20A or will it be a problem if, for instance, 400W are provided to victron and then : 400/12 => I = 33A. Will battery charge current be limited to 20A ? or will it break the victron ?

best regards

Anyone come across a solar radiation sensor with output voltage proportion to incoming insolation. Would like to record the values with the Venus GX.

Hi Victron Community,

I hope these stressful quarantine days find you well.

Let me explain what I have and what I want to accomplish and maybe you can help answer some of my questions and concerns

I am making switching to electric propulsion on my 43'(13.1m) yacht since the 40 year old Diesel Buhk/hydraulic drive system has seen better days.

For this I am installing a Fischer Panda 8000 NE PMS 230VAC 50Hz max power 6.5kW

The propulsion motor I am considering would be 48VDC with around 15 to 20kW of power with an expandable 48V 100 Amp-Hour battery bank

I also want to solar panels provide some level of charge as I am planning on cruising to the south pacific islands.

I have been considering the EasySolar II GX setup since it seems to have all of the parts in one unit.

One of my fears is that it's IP rating is 2.1, which would mean that I would most likely have to install the unit in dry locker that is constantly ventilated.

Would you recommend going this route of would you go for separate components for each one of the functions of the EasySolar unit, meaning, separate charger, inverter, MPPT solar charge controller, battery balancer etc... Price would not be an issue, as I estimate the costs of having to replace the EasySolar unit would offset going the separate route.

I think it's a big decision and it's possible to argue for both configurations:
1.On the one hand would like the fact that I could maintain each of the functions separately in case either of them fails, whereas with the EasySolar I imagine it would be very hard to debug issues since it seems like it would all be bundled together, and the low environmental rating makes me think it would not be very well suited for the marine environment.
2.On the other hand having everything centralized in a neat small package would make it indeed easier to accommodate in a very well designed dry locker with proper ventilation and possibly a small dehumidifier.

I apologize for the long message, but I seem to have a lot of spare time these days and it's got me wondering.

Let me know what you think.

Kind Regards

What would be the ideal settings/recommendations for SOC for the Venus GX/MPPT to maximise the use of solar power and minimise the use of (expensive) grid or generator power on a yacht. Details: battery OPzS 980 Ah, Victron Quattro 24/8000, MPPT 100/50, 4 x 350 Wp solar array, grid 230 V 16 A, generator 4 Kw.

During the day there is a discharge of about 4.1 Kwh when not present. When just visiting during the day and using some equipment discharge will lead up to 5-6 Kwh. Fully living on the yacht will lead up to 9-10 Kwh per day. Yacht is fully equipped with fridge/freeze, oven, dishwasher, microwave, combination washing machine/dryer, central heating, led lights, etc.

My idea was to let consumers discharge the battery to 40 % before the grid/generator kicks in and the Quattro will start charging. Should the Quattro then charge to say 70 % and let the solar take over to charge to 100 %? Or maybe it is better to let the Quattro charge to 100 %?

Any thoughts?

Hi, I have the following configuration:

• Victron MP2 5000 / 70amp charger
• SMA 5000TL-21 solar inverter on AC-Out#1
• Pylontech US3000 batteries
• Color Controller

If I have to turn the SMA inverter off and then turn it back on later, the CC display looks like this (still) after 15 minutes from turning on the SMA Inverter:

[image]

You can see that the Solar inverter is working because it is exporting, however:

• SMA inverter is not shown,
• AC Loads are not registering (=0) despite being around 600W.

The SMA is remembered:

[image]

But does not appear on the device list:

[image]

This has happened a few times and it often takes hours before the display corrects itself.

I was running FW 2.51 on the CC but saw that 2.52 was available, so I installed that, but alas, still the same problem.

The CC and SMA are both on the same subnet and I can confirm that the SMA has obtained its IP address which is fixed by DHCP settings. I can confirm this by the SMA front panel.

Is this a known issue?

thanks for your assistance,

Ron

Hi. Just wondering whether or not there is any difference in terms of functionality and remote control between Smartsolar VE Direct and VE Can products. Is there anyone that have some experience with both that can explain?

Thanks in advance for your help

Hello community,

I need some help please!

I have just installed my system:

1 x Multiplus 48/5000

1 x SmartSolar MPPT 15/70-TR

1 x Venus GX

1 x PylonTech US2000B 2.4kw

12 x 350w Canadian Solar

ESS is installed in 'Keep Batteries Charged'

DVCC -ON

My PV is peaking out at about 3350W. It seems that something is throttling the system.
I have followed the setup recommendation for the Victron/Pylontech setup.

System has been running for 2 days. When I first set up it would not work on ESS 'Optimised without Battery Life'. PV was on and then off, on and then off. I then setup as 'Keep Batteries Charged' and PV worked fine. End of the day, still on 'Keep Batteries Charged' the system went crazy again with PV on, off, on off, on off. I looked closer and it seems liked the 'State' on the MPPT was ESS/Fault.

I then reset as much as I could and everything started working again today. My PV is still peaking out at about 3350W.

Surely I should be getting at least 3800w out of the max 4200w? Is there anything I am missing?

Does this have anything to do with the jumpers on the underside of the MPPT? (untouched out of the box)

Unloaded my voltage is 130v on both strings of PV. Loaded it drops between 94v and 107v

Any help will be much appreciated.

Hi can anybody give me some basic instructions on connecting a Solas 4G mini inverter AC coupled to a Victron Multiplus 11GX

I am installing 4 170watt panels each with its own VictronConnect mppt controller with Bluetooth. I have a Bluetooth BMV712 as well with a temp monitor for the battery. Will this provide sufficient coordination between the controllers to receive common voltage and temp data or should I add a GX module for better performance?

Hello community,

On the smart solar charge controler, we have PV pannel, Battery and application as everybody know.

If we have some issues because of bad weather or anything else, the application continue to take current on the battery (that's make sens...).

We the battery is empty, the S-S-C-Controler cut off the application to prevent an over discharge of the cells.

That's good, but in case we cannot recharge quicker the battery, the smart solar controler consume a little on the battery, to be able to keep an intelligent sytem to put ON (after a good charge level on cells) the application after.

We loose all if the solar cannot be recharge the cell before the over discharge (because of control consumption on battery)?

Can we programm (configure) the smart solar in a sleep mode and for exemple create a wake up every 15 minutes ? So we could reduce a lot the controler consumption on the battery.

Hope all is clear....

Thank you for any feedback.

Best

I'm looking to set up an off grid van system. I have 4x 150w of solar on the roof and 2x 150ah of basic lithium batteries.

I was planning on fitting:

Smart Solar 100/50

Orion 12v/12v 30a (Poss x2)

Multiplus 1600va

BMV 712.

Smart Battery Protect 100

The batteries have a basic BMS, with low voltage and over voltage protect, but I would like to have low temp protect and be able to set my own DOD alarm and cut out. How is the best way to connect and program this system? I have looked into the set up guides and there seems to be many different ways. I also wonder if the different charging units may trip over each other during charging, ie DC to DC and Solar when driving or Solar and 230v Charger when plugged in. Is there any way of syncing them to work as one rather than each unit doing its own thing?

Hi,

Have a SmartSolar MPPT 75/10 and an 80W solar panel.

I wish to upgrade the panel and I am confused at to how much solar I should stick on the roof. I am limited to 10amps. Am I correct in saying that if I put something like a 175w panel (or larger?), depending on conditions, the charge controller would limit it to 10amp? (It is currently set to that)

Any thoughts and/or recommendations on a suitable panel

Hallo,

I have the MPPT 75/15 unit installed in my 4x4 and connected the the Auxiliary battery for solar charging (using a 100W solar panel) as well as to manage the load output. Since solar may not always be sufficient in high demand situations (and/or not able to charge via alternator when stationary), I plan on connecting a BluePower 12V/15A charger to the mix where camp sites may have 220V power.

If both devices are directly connected to the battery (with the MPPT providing solar power to battery), will there be any risk when the Charger is plugged in and also providing charge to battery? Will the MPPT detect this higher charge on the battery and then go to float mode (or switch off)? Any settings I need to make on Connect App?

Thanks

Brian

hello,

on the manual of the muti plus is written this:

"When solar inverters are connected to the output of a Multi or Quattro, the excess solar energy is used to recharge the batteries......"

but what is with the phoenix inverters ?

what happens with the phoenix inverter when a solar inverter is connectet to the phoenix inverters output ?

Just installed a 12v lithium battery and a 100/20 controller to my caravans existing 120w panel. When I'm not using the van I intended to disconnect the battery from the controller and leave the battery at a storage voltage.

Is this advisable? Can the controller dissipate the power generated from the panel?

I have 2 100/30 Smartsolar MPPTs integrated with a Quattro 5000 into an ESS, running on 24V lithium batteries. That system consists of 4 panels in 2x2 in parallel.

Can someone please explain to me the reasons for the attached pic?

It's a snapshot of the last 48 hours worth of charging. Both were equally sunny days (actually day 2 was sunnier). The batteries reached a nice good charge of around 95% (possibly reaching absorption voltage) on day 1. Then through the day's consumption, day 2 started out in the low 70s% SOC. But as you can see from day 2, hardly anything came in. The day finished up slightly higher @~75%. Why?

There was plenty of sun. The batteries clearly needed the charge. Yet?

It's obvious the system tried to hold some voltage on the batteries and I'm confused why. This is not the first time this has happened and I'd like to understand how to stop this unproductive behavior from reoccurring.

Thanks in advance,

George

Hello
A customer asked me the question if its possible to connect two SmartSolar MPPT`s to one string of 3 parallel PV-Panels.
The reason behind is, there are two diffrent type of Batteries (one bank is Lead-Acid Battery, the other is a LiFePO4 Battery).

He would like to charge both with the same Solar Array.

Is this possible?

Tanks for your Help.

Hello,

On the following page there is a section about "New: monitor SMA & Solar Edge PV Inverters". This section also mentions that only Solar Edge models SE2200H – SE6000H (HD-Wave) were tested.

https://www.victronenergy.com/blog/2018/02/14/venus-v2-12/

In my current Solar installation I'm using a SolarEdge SE10K inverter, this is a three phase inverter. I was curious if someone has experience combining a three phase SolarEdge inverter with for example a Victron Venus GX.

Thanks!

Emiel

Dear all,

I try to figure out, if the behaviour I see is per design or not. In my van I have installed a Victron LifePo4, a BMS12/200 and a MPPT75/15 with 2x110W solar panels. Due to the current cold weather conditions (<5°C), the battery and the BMS shutdown the battery charging.

Whenever there is sun available, the voltage on my BMS load and the MPPT battery output increase to ~17V. I assume this is due to the battery shutdown for charging. As soon, as the battery is open (>5°C), the voltage decreases to a normal level.

Is that expected? I thought the MPPT will reduce somehow the voltage when there is no charging in progress.

Why I am asking the question? If put the MPPT battery charging minus on the BMS load pin, where all my other load is also connected to. Now I have ~17V on all my devices, as long as the battery is shutdown. Is my design correct or do I need to change something?

best regards,

Fabian

Hi all,

I'm trying to spec out a 6kWp solar system with a Quattro 48/8000 and a 48V/200Ah lithium battery. The solar panels will be connected to the DC input of the Quattro

I have an EV and would like to use a Mienergy Zappi charger to charge the EV using solar power as much as possible. I'd also like to use a PV diverter (Mienergy eddi) to heat the water after the batteries have been filled in summer.

Ideally I'd like to design the system so the EV charger and immersion heater don't drain the battery bank.

From my understanding of the Quattro manual, I should connect these loads to the AC-2 output which will only use Grid power.

My question is, will that also prevent the EV being charged from Solar power? If so is there a better way to connect the system, for example can the Quattro prevent the batteries from being drained when particular loads are active?

Hi,
My VRM data displays 20kWh in the middle of the night 00:00, this mess upp the data over time.
Is it possible to edit the data on VRM? This must be wrong, there is nothing displayed in System - PV yield.

Just found out that Solar Plants went into liquidation just before Christmas and they are no longer trading.

Im fuming given that they are half way through my installation and I’m currently significantly out of pocket. I believe a company called Climate Save Renewables is taking over the Solar Plants business.

Is anyone else in the same boat or have any information?

First post - A little guidance please on our design below:

We have 48 PV Panels each has an Enphase 215w micro inverter.

We have a genaration meter as part of our FIT

Our utility provider has installed a smart electricity meter to track half hourly usage

Would the below design work for us?

Our decision to connect the PV to the critical loads output (AC output 2) of the Quattro is to ensure the continuous supply from PV and battery in the event of a grid failure.

1) If we connected the panels to the Critical load, as mentioned in step 1 of the installation guide video at 7 minutes into it (https://www.victronenergy.com/live/ess:quick-installation-guide) - Would this work without the need for the additional ET112 meter?

2) With this setup, would we have use of the CCGX to show system energy flows and be able to control the system via the CCGX?

Thanks

Need help on how to do Zero Current Calibration on my set up:

Manual says that to do a zero current calibration "ensure there really is no current flowing in or out of the battery" and "disconnect the cable between the load and the shunt, then press 'select"'

What do they mean by "the cable between the load and the shunt"? and is that really enough to ensure "zero current flowing in or out of the battery" in the case of my set up?

I have two batteries. One negative cable (the one being fully monitored, call it the "main" battery) goes to the "bottom" of the shunt and the other battery (the one with the voltage only being monitored) goes to the "top" of the shunt. Then a "common" cable goes off the top to the common ground.

I also have solar positive and negative leads going from my solar charge controller directly to the main battery

Finally, I have bilge pump, gasoline fume detector, Victron MTTP 100/15 charge controller and Blue Seas ACR all with positive leads connected to the main battery before the battery selector switch and with their negatives going to the same common ground as the BMV 712

So in order to do a zero current calibration and "ensure there really is no current flowing in or out of the battery" would I

1. Disconnect the solar source (disconnect at solar panel end)

2. Disconnect the "common" negative feed off the "top" of the shunt.

AND

Do I also need to disconnect the charge controller, ACR and fume detector in order to accomplish the zero current calibration?

thanks!

1. Hello everyone,

After installing a 3-phase AC coupled system with 6 quattros an a PV inverter connected to AC out of Quattros, we realised that the Quattros cannot connect to grid (AC in1) when the grid operator swap 2 phases. The problem is that the grid operator often swap phases during maintenance of electrical network, and after which the quattros cannot connect anymore to Grid when energy comes back. Is there anyway to change setting of quattro so that they can still connect to grid even if the operator swap 2 phases?

I'm considering replacing my solar controller (Outback FlexMax + accessories) with a set of two Victron 75/15 and the Color Control GX for monitoring.

I have seen the VRM portal details and docs on the JSON API to get data from the portal, but I need to get data locally via TCP/IP, without relying on an active internet connection. From the documentationI've read it is not very clear if this is possible or not.

What are the possible ways of getting data from the Control GX via the local LAN?

Also, what Victron products do I need to monitor battery input/output? In my current system I use a FlexMax FNDC with several shunts for the different charge sources and between the batteries and load. I'd like remote access (via VRM and on local LAN) to all this data so I can analyze it using customer software.

Thanks!

Hi, I have an existing grid-tied SMA inverter (SMA 5000TL) and 2 strings of 13 panels for total of 6.5kW. I want to add storage and am considering the QUATTRO with 4 x Pylontech US3000 batteries (@48V nom).

The main aim of the exercise is to be self-sufficient in case of extended/indefinate grid outage. I am no expert, but my reading suggests that the Victron QUATTRO would provide a mini-grid on the AC-OUT-1 and that the SMA solar inverter would run 'normally' on this channel regardless of whether the grid was connected or not.

Assuming that the above is correct, would the SMA inverter connected in this way be a stable and reliable configuration. I ask this because I have read some posts/articles that indicate that there are situations where the inverter may go over-voltage and shutdown the QUATTRO.

Is this a potential problem, and what would be the recommended way to deal with this?

Note, the loads would include 1000W and 1500W pumps (bore pump etc), inverter aircon, fridges and freezers, lighting and misc.

thank you,

Ron

I have an array of 3x150W panels wired in parallel to my MPPT 100/50 controller. On a clear sunny day with no shading and clean panels, I've never seen the controller show more than 200W. What's the best place to begin to troubleshoot?

Hi there, community!

I wanna charge my campers’ leisure batteries both via the alternator (Orion-Tr Smart DC-DC Charger Isolated) and solar (SmartSolar 100 / 20 20A MPPT). Can I use both products simultaneously? Thanks!
