Currently I have a solar controller Sunware Fox 320.
This controller can load 2 different batteries, currently the starter battery for 10 minutes und the consumer battery for 50 minutes.
Is there a similar controller in the viltron portfolio?
Thanks in advance for your help.
In a previous post I shared the scheme of my Van electrical system. It is almost set now, but I have some small doubts...
Mostly about Negative / Ground
here I share a scheme with three options on how to connect Orion 12/24 to the negative busbar
which one is more correct?
Howdy! I'm looking for a little help as I've figured out the beginning and end of my solar set-up but it seems like there's multiple ways to fill out the middle. I was originally piecing together a build based off of youtube but I like the idea of a mostly victron system where I can still cheap out on a couple of the components.
Here's what I'm working with so far:
My panels are going to be wired in series so I've been eyeing up the EasySolar II since it seems capable of handling the 200v input from the panels. I will be using 120VAC and 12VDC in the bus so I need to figure out the best way to handle the 240VAC output from an easy solar II unit.
Alternatively, it seems like I could just get a 250|70 mppt solar controller and work that into a cheaper 2000W 24V inverter connected to a battery monitor and then the battery bank.
Will there be a 120v easysolar ii coming out? Is there a different product(s) that makes better sense for assembling my system?
Side question: how feasible/complicated/expensive would it be to integrate my 24v solar power system with the 12v system of the schoolbus?
Thanks in advance for any insight!
Appreciate you stopping by. I’m new to this area, but I’ve done a bit of research to solution for various other issues.. That said, i now am a bit stumped and would appreciate some help.
Background on my set up:
Configuration for Victron systems:
Pictured below are my key setting configurations for my set up. I used the manual as well as some other threads to determine my settings.
Settings for the 100| 30 Controler :
Settings for the 712 Smart Monitor:
Any help is greatly appreciate. Happy to provide more details around certain aspects.
Here are some additional data grabs...
Below is a picture from the monitor today while having a slight load on it (fan, heater, lights):
Here’s a picture of the van when I bought it.. It’s changed a lottttt since then.
If anyone could tell me what is the name of the plug/connector type model I would be much happier person :-)
I did check documentation also looked at different connector types and could not find a simple thing - what is the connector type model. I also can't find Victron cable that is meant for this port.
Here is the photo of the port itself:
Earlier today, right before noon, my main solar panel array on SmartSolar 150/100 stopped producing power. My smaller one (100/30) is still working. It was decently windy today, but my panels have survived much worse. I walked the cable and everything appears fine. Open circuit at the panels is 114v, right before the MPPT is 74v after a 150foot aluminum cable run. When I connect it to the MPPT, the panel voltage drops to that of the battery voltage and there is zero amperage. I tried resetting it, disconnecting and reconnecting it, etc. Does anyone know what the problem could be? This has bee working great producing 3k+ watts for the past few months. Here's a screenshot of when the failure occurred - is this a hardware issue?
Hello, my mmpt smartsolar 100/20 indicates a nominal pv power of 580w.
I don't understand why is this value indicated as the datasheet indicated that maximum current will be limited at 20A and maximum voltage supported is 100v.
Then maximum power should be 2000w.
So why is there a limit of 580w indicated?
nominal pv power means that sum of WC of each pannel should be lass than this value right ?
Hi I want to update my solar installation. It is in a boat, alway anchored,so she is moving all the time around the anchor. Weather is always tropical, close to the ecuador
To update it, I though to set 2 solar panel, 450W each one, in series, 900W. Voc= 49.27 and Vmp=41,37 I want to use MPPT 100/50. If I set the panels in series, Voc total is = 98,54v. It will be 2 sets, 2 regulators, 4 panels, and total 1800W. If I use bigger regulators, I should go to 150/60, so I will double the budget, as I will have 2 sets
Please my questions:
1º - PV MPPT 100/50 limit is 100v. Can it be keep it below limit with stated above, keeping in mind that the PV would be always between 15ºC and 60, and I can assume that it will be some lost in 6 cable meters and joins?. And important too, in a boat, with my old installation, I never reached maximums, as the boat is always moving around the anchor, so there is no a optimal and fix orientation towards the sun, and there are some few objects (mast, aerogen, radar), which cast shadows to the PVs?. E.G., in my old I have 500W, but never got more that 340W( 14vx24A), with sun at zenit
2º In the same way, what is the tolerance +/- of the 100v limit for the regulator? Within the manual, there is nothing about it. I meant, if the real limit is 120v, it will be safe I guess.
3º Can I put in paralell the 450w PV increasing AWG cable but lowering the max voltage? I guess in a MPPT would be not suitable do that?
4º Can I set a voltage limitator for 100V just in the inbound of the regulator?. Maybe some kind of varistor.
5º I tried to use the victron excel tool, but I couldn't as per there is some problem if you open it using open office (xlsm format), and I cant use with excel 2003. I tried with opencpn, but it was overflow (value!), when I tried to set parameters, and a new PV , custom. Any idea?
Thanks for your time, BR
I have a van that I am building out and trying to straighten some things out in my system as I design for kitchen.
I am hitting a lot of points where the inverter just won't budge though. Sometimes I'll be at a good charge say 75 - 80% of capacity and the inverter light will switch to "low battery" when I turn on the 1k watt hot water kettle. Really, at 1kW? No go. If I start the car, the kettle works. I haven't even bought the induction stove yet since I'm running into these issues.
I saw somewhere that potentially I would need at least 3 x 100ah batteries just to give enough current to the 3K W Inverter to do its thing. Is that right??
I'm hesitant to drop another $1k on a battery, although I would do it if it let me run my whole setup with the induction stove smoothly. It starts to worry me though that maybe I couldn't fill the 300ah battery bank fully with only 400W of solar. I've heard good rule of thumb is 200W solar per 100ah battery charge. I have enough room on the roof for another 50V panel..maaaybe 100W. So I'd be at 450W-500W, not the ideal 2:1 ratio. I do have an Orion that charges while I drive... so there is that. I would hardly ever be parked anywhere for days on end without moving. This is mostly a family extended trip mobile. Going for several days up to 2 months at a time remote work/travel trips. I also have a shore power hookup but don't plan on relying on that for steady refill, more of an emergency backup thing if in a pinch.
The other option would be to just swap out the 3k W inverter charger for the smaller 2k W inverter charger - if that is in fact a more appropriate current draw on 200ah batteries- not buy another battery, and just go propane setup for the kitchen stove instead of the induction stove. Thoughts? What say ye?
Hey! Please advise, it is possible:
Q1: Will solar energy be shared between AC Out #1 and AC Out #2?
Q2: If the consumption is small during large PV generation, is it possible to set up a power discharge to the grid?
Q3: Do I understand correctly that when AC Input #1 disappears, AC Out #2 will automatically turn off?
Ik heb thuis een multiplus II GX aangesloten op het Net met een 10Kw lithium batterij.
Alles in mooi aangesloten zoals het in de manual beschreven staat en het systeem werkt ook gewoon perfect, Maar nu is de keuring langs geweest om het systeem te keuren en dat wilde hij niet doen omdat de omvormer in serie was aangesloten met het electriciteitsnet en niet in parallel. (Ik vertelde hem dat dit systeem enkel maar in serie kan worden aangesloten en dat alle meet apparatuur vanbinnen in de multiplus aanwezig is, en dat dit toestel aan alle veiligheids voorzieningen voldoet en gekeurd is door Synergrid belgie)
Kan iemand mij helpen met info of voorbeelden van iemand anders die dit ook zo gedaan heeft thuis, zodat ik dit kan voorleggen aan de keurder? Of heb ik zelf iets over het hoofd gezien?
In bijlage de schets van hoe het is aangesloten:
Met vriendelijke groeten
I purchased this system (https://dakotalithium.com/product/dakota-lithium-12v-200ah-battery-plus-zamp-solar-panel-and-victron-bundle/) with an additional 170w solar panel. I will be running a cooper and Hunter mini split 12,000 btu at 120v. considering misc items plugged in for charging what size (kw) electric water heater can I get away with. Also the inverter can be switched to put out 240 @ 60Hz. With that being change will I still be able to operate the mini split. I can get additional 100Ah batteries if needed. Please help.
Good day all,
Apologies if this has been asked and answered already. I have been searching for a couple of days now and not been able to find the answer yet.
I am in the process of upgrading and installing new batteries as well as a larger solar array on my boat.
I have bought 3* 220ah Victron deep cycle gel batteries.
My solar so far consists of two 365W panels with a Voc of 41.13V and Vmp of 33.96. the current ratings are 11.30 lsc to 10.75lmp per panel.
My plan is to connect these in series. I will be adding some more solar to these, probably 2 150W panels at a later stage.
According to the information I have been given and my calculations, the max carging current for the batteries will be 44A.
My question is this:
I have been advised to get the 150/85 MPPT controler for this as it can take up to 1200W for a 12V system. Is this really needed if I need to limit the charging current to 44A. Will a smaller MPPT better/worse for the charging of the batterie bank? or will it make no difference?
Kind thank you in advance.
I would like to put this out to the community to see if I am missing anything in the way I currently have my system wired before I power everything up
I have 10 battleborn lithium batteries divided into two banks interconnected with 4/0 cables.
Each banks positive goes through a 400 amp class t fuse then through a battery disconnect and over to a 1000 amp buss bar.
Each negative goes through a smart shunt and then to a 1000 amp buss bar.
Cables are within inches of being the same length slight variance due to placement of switches
Inverters 2 Multiplus 120v 3000
Each inverter positive and negative go directly to the the buss bars using two 2/0 for both pos and neg
Each inverter casing is grounded to the motorhome chassis local to the inverters
Cables are the same length
Charge controllers 100/50 x 4
Each pair of solar panels go through din rail pos & neg breakers to the PV input on the controllers over 10awg wire. The wire calculator I used was border line 10 or 12 so I went 10
Each output of the controllers battery side goes through a din rail pos & neg breakers then on to the buss bars over 6 awg wire
Charge controller chassis grounds are daisy chained and terminate on the motorhome chassis at the same point as the inverters
Cables are the same length.
Motorhome DC distribution
I am using the existing motorhome 3/0 inverter cables to supply voltage back to the original battery compartment where the original chassis ground is, dc distribution and alternator cables go to.
AC 120v 50amp
AC comes in from either shore power or the generator through the transfer switch over to a double pole 50 amp breaker then the ac is split into two circuits 1 going to each inverter.
AC1 out on each inverter is fed to another 50 amp double pole breaker and then continues to the main AC distribution panel for the motorhome each inverter feeding one leg of that distribution panel
AC cabling is within a couple feet of being the same length. Not sure how critical the symmetry is when running separate legs of the ac panel since the inverters will not share each other’s load.
Is there anything I am missing here?
I have a project that requires an off-grid battery storage and inverter solution. I have a 120vac 10amp load that needs to be brought off grid. I don't care which battery config (12vdc, 24vdc, etc.), but if I can manage it, I would like for this entire project to be purchased from one vendor (ie Victron). They only thing I would like to incorporate that I already have is the Yangtze solar panels listed below.
Load: 120vac, 10amp
Calculations I'm using for reference: https://www.batterystuff.com/kb/tools/solar-calculator.html
Is it possible two use two Multiplus in a three phase system with a seperate battery bank for each Multiplus.
Each battery bank has its own BMS. And should be charged/discharged by its Multiplus individually.
I already have one Multiplus running in a solar setup with ESS and three phase energy meter on the grid. The Multiplus is connected to the Venus GX. It's connected to the first phase on the grid side.
Now I want to add another Multiplus with its own battery bank to have more capacity and redundancy. This shall be connected to the second grid phase.
Can I setup both Multis individually? Will the ESS take into account the two Multis for calculation of phase compensations?
I have an RV and am looking to consume Solar first then the grid or have the Solar off set the grid.
I’ve done research but can’t seem to find clear guidance on how / what needs to be done for my system in order to prioritize Solar over the Grid and would appreciate any help.
Multi - 3000kva/120v
SmartSolar MPPT 100/50
6 - 100w Panels
440A AGM Batteries - 12v
Overall, I want to offset the grid consumption with any available Solar.
Hello VE community.
I am a solar developer professional but not as technical as I pretend ...
I have a personal project to create a "Solar Portable Box" with Lithium batteries to run amplifier and speakers in remote areas with a MiltiPlus 800VA + SmartSolar 75/15.
If I have no doubts regarding the functionality in "Off-grid" mode, I would like to know if I can :
(1) - Do a rapid charge of the batteries from a wall power outlet without waiting from solar.
(2) - In order to amortize the costs, use the solar box to inject energy (solar + battery) at my place in self-consumption using a wall power outlet of the house. The grid would take the peaks and back-up. I don't want to perform some BTM cabling each week end.
If both of these on-grid modes work, I would really appreciate your support with the AC ports to use and eventual settings to be adjusted (if any).
Thank you very much for your support
I have connected everything according to the instructions. When not connected to the car, the solar is coming in via a voltage relay switch. In the app it's showing 19 volts coming from the solar panel and I'm get the error: 'charging disabled' and 'remote input not activated'.
Am I doing something wrong? Do I need a regulator to bring that voltage from the solar panel down? What am I supposed to do with the jumper?
Help greatly appreciated.
I'm planning an installation for a small workshop in a location where grid power is limited (230V/10A). There will be a constant load (heat pump) plus peak loads for a short period of time (say up to 6kW nominal power for a minute or so, when power tools are being used). I would like to supplement the available grid power with batteries for those peak loads.
I found the MultiPlus (48/5000/70-100) and it seems that its PowerAssist feature is exactly what I need. So far so good.
But — I could also add a small amount of solar to the mix. And that's where I don't understand things anymore.
Ideally, I'd like this ordering of power sources:
1. Use as much solar as is available at the moment.
2. Use the AC grid connection to pull up to 10A.
3. Use the batteries for anything on top of that.
But it seems that the MultiPlus does not have a separate DC connection for a solar power source. I found a system example (https://www.victronenergy.com/upload/documents/MultiPlus-system-example-5KW-24V-230V-AC.pdf) which is fairly close to what I want, but it seems that the output of the MPPT controller is connected directly to the batteries. It seems to me that in this system, if I configure the PowerAssist feature, the solar source can only supplement battery charging and supplement the power peaks over the 10A I can pull from the grid, but it can't participate in small loads if the batteries are fully charged?
I would like to avoid discharging the batteries as much as possible, to extend their lifetime. They should be used only for supplementing peak power above what grid+solar can supply at the moment.
Additionally, I do not understand this example: I thought batteries need to be charged according to a charging profile, and it seems like there are two chargers connected to the same batteries. How does one ensure proper charging?
I think what I was expecting was an inverter/charger with separate connections for battery and for DC in (from solar/wind), with source prioritization.
Can this kind of prioritization be done with the MultiPlus?
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.
[image]I just installed my Victron system. I have the multi 3000 with a smart dongle, smart solar 100/50 mppt, 1000amp smart shunt, and 420ah of safari ut 1300 lithium’s. Up top I have 4 200w panels wired in series parallel dumping 45ish volts and 25ish amps into the mppt, but coming out to the batteries at the terminals on the mppt, it’s on 8ish amps. Not sure if my setting are off? I’ve googled until my fingers are raw.
First solar installation! Uses MPPT 75/15 solar controller and Victron 90Ah gel battery. After two summers, the batter is no longer holding charge. Is this normal life time for this battery?
Am about to embark on deploying a Tiny House for off-grid. I've built the Tiny house based on an RV design. Major appliances, like On-demand hot water heater, 3-way fridge/freezer, 3-burner oven/stove, propane heater are all driven by LPG, Lights, Ceiling fan, and USB charging ports are all 12v based. Utilize a Natures Head composting toilet which requires small amount of 12v to drive a small exhaust fan.
The Tiny House was built with a Power Dynamics Power Distribution Center (PD4045LIKA), 30AMP input. So all 120V outlets and 12Vdc circuits are wired to through this unit. The PD4045 is a Converter/Charger and I have disconnected the circuitry for these, as the Victron MultiPlus Compact 12v/2000/80 I have installed will feed the AC and DC side of the PD4045 and also charge my lithium batteries.
As I'm not a Pro am looking for any advice/recommendations with regards to this setup.
I have installed a 150/35 MPPT Smart Solar charger in my van and it is driving me crazy with the noise it produces. Once I disconnect the solar panels, the noise is gone.
Is this normal, something I have to live with or is there anything that can be done?
Hello, I am looking for advice regarding updating my current solar panel setup on my leisure vehicle.
Currently I have a single 80w panel and a Victron 75/10 controller. With weight on the roof being the constraint, I think I have three options:
What do you think would give me best yield, all year round in the UK?
Many thanks for looking.
I noticed with the recent ESS update the inclusion of a "new feed-in limiter". Woah-and-behold, there is a seeting in my CCGX for max watts feed-in!
Previously, I've just had a current limit set-up that when feed-in starts to exceed, the inverter drops ALL feed-in momentarily. What I wanted however was a more dynamic reduction of the MPPTs.
I was hoping this new setting would do just that, limit the incoming PV to reduce my feed-in such that it regulates at the set-point (if it is able to exceed it).
It seems however it does the same thing, just dropping all PV momentarily, then ramping back up. Cycling over and over.
Is this how this is intended to work? Certainly not ideal as I suspect the load fluctuations are putting unneeded stress on my setup.
For reference my system is as follows:
Quattro 10KVA (VE.Bus),
2x victron 150x45 MPPTs (VE.direct),
victron BMV (VE.direct i think),
Would be grateful for any advice! :)
Ich habe folgendes Problem und auch in den anderen Feeds leider keine passende Antwort gefunden.
auf dem Dach unseres Wohnmobils sind zwei baugleiche Solarpanele mit 110 Watt verbaut. Wir betreiben dazu den Victron Laderegler MPPT 100/15.
leider zeigt dieser immer nur eine Lading von 0 Watt im Zustand Float an. Und dies auch unter Berücksichtigung der 5 Watt Differenz.
- Batteriespannung: 13,42
- PV: bsp. 20,41
Auch zeigt die Batteriespannung bei einer Messung an der Batterie lediglich eine Spannung von 12,9. wie kommt es zu solchen Abweichungen und wieso lädt der Regler nicht?
Hi Victron Community,
I want to convert my AC water heater to DC.
Can I connect my 12VDC 600 water heater element to the Load Out on my MPPT Solar Controller to run only when my batteries are full?
Here is my setup:
2 x 375w panels connected to a Victron MPPT SMART 150/60
2 x 175w panels connect to a Victron MPPT SMART 100/30
This is going into my LifePo4 bank 4 x 120ah.
Whats are your thought on programming the two MPPT Load Outputs to act like a dump loads from excess energy created my when batteries are full?
I can put two elements into my tank so have two separate heating elements with thermostats.
I'm trying connect my 260ah AGM battery and 320w solar panel to my mppt 100/20. It registers the battery but I have 0w and 0v from the solar. I've triple checked the wires are connected properly and the right way round. I've checked the fuse and I've checked the wiring using a multi meter and there is power coming from the panel but the controller still isn't recognising it.
I'm aware it needs +5v above battery voltage to charge but I'd have through midday on a sunny day it would produce that easily.
What am I doing wrong? Anyone got any thing else I can try?
Thanks in advance.
