charge controller compatibility

I have an 18S NiMH battery pack with connected in 12 parallel and I want to charge it using my SMART Solar 150/60 or 75/15. Has anyone had success using NiMH batteries with solar? I know that I'll probably need a BMs and any suggestions would be appreciated.

Hi,

Historically I have always spec'd systems with a battery protect to turn off the charge controller through the VE.bus bms. However recently seen schematics on Victrons page showing the charge controller connected directly to the CCGX with nothing to turn the charge controller off.

Has this been changed so the comms can control the charge controller based on what the BMS needs?

I want to use two power sources to charge a battery, which will in turn power a motor. I need to know how to design the circuit required so I can charge the battery from two sources

hi, i would like to know if victron mppt charge controllers support wind turbines? if yes could i run 2 controllers in parallel, one with solar and one with a wind turbine?

Thanks

I have been having issues with my charge controller.

I have one solar panel (specs below) connected to the "Victron 100/20 SmartSolar MPPT" charge controller. When I tested the panel directly, the multimeter was reading 37.2v.

There are 2 x 12v leisure batteries (haven't been charged in a while) wired in parallel to the controller. The controller light flashes blue when the batteries are connected, but no change when the solar panel is connected.


Solar Panel specs:

Maximum power (pmax +10%,-0% - 245w
Short Circuit Current (Isc) - 5.86a
Open circuit voltage (Voc) - 53.0v
Maximum power current (Imp) -5.54a
Maximum power voltage (Vmp) -44.3v
Mamimum system voltage -1000v


Readings from charge controller:

Battery: 12.49v
PV: 12.3
Load: 12.49v


I tested it again after a few hours and the Load was 12.45v.
Are these the reading I should be getting? Or is something in my set up wrong? I was told this controller would work in creating a 12v system (very important, don't want 24v).


"Nominal PV power, 12V - 290W":

Any help would be much appreciated.
Thank you.

Hi, I would like if someone with more experience than I can help me to solve this. Actually we have an Off-Grid site with 4 PV strings, every string have 16 50w solar pannels connected in serial-parallel to get 24V to the power bank (14 batteries 12V 100Ah each battery). Each string have a Morningstar PS-30M, but they are connected in parallel on the load port and works well, but we have to replace them, because they have more than 20 years in use. I have seen that a Smartsolar MPPT 150/35 is a good option, but we can't connect the battery banks in parallel to charge the batteries because they are in 2 different places with a distance between them of 4 meters (around 8 meters of cable difference between the longest cable and the short one, so they could have a difference of the charge voltage. How can we connect the battery banks to the load with the Smartsolar and maintain the 4 battery banks?

Thanks a lot for your help.

I have a Quattro 48/10000 in an off grid solar system with BYD batteries It has a backup power supply via a Honda EG5500 CXS fitted with a 2 wire autostart. The generator can be started from the colour console but the inverter does not sync with the generator and disconnects. Generator supply is 240 50 Hz but apparently split phase. Do I need to change the generator or is there a serving on the Quattro to accommodate this?

Does any one can help me if this type of controller mppt 75/15 is suitable for this type of pv.

Hello,

We have a small wind turbine that charges a small battery bank that is only used as a buffer for a 240 inverter that goes into a 240 cable about 70 meters and charges the main 12V battery bank there via a Victron Blue smart 10A charger.

The main bank is also charged via a Victron smart solar charger.

Both battery banks are about to be replaced so would like to know if there is a better way to do this, before we buy new batteries.

Q:

Can these two chargers sync via Blue tooth to optimize shared charging of the batteries?

Can the Blue Smart charger output be connected over the Battery smart shunt, as any load?

Many thanks for any hints on how to proceed!

Hi all,

Our caravan is set up with Victron Lithium set up and has a Buck-boost dc-dc converter. The problem is that it doesn't charge when van is stationary and tow vehicle is running.

Can this be programmed to work with no vibration (or do I need to change to a different unit).

The second Q I have is does it shut down if the tow vehicle is putting out around 14.5 volts if so can it be programmed to accept tow vehicle voltage or do I need to reduce voltage from tow vehicle.

Thanks in advance as the caravan manufacturer has no idea even though they fitted the setup.

Darren

Greetings,

We have a customer who has a Victron Smart MPPT 150/100 - Tr. He's using it with a Schneider XW+ 5548. Does anyone know of any incompatibilities between the 150/100 and the 5548, in particular anything that would prevent the 5548 from selling to the grid?

We're combing through settings looking for something, anything, and it is a bit of a head scratcher.

Thank you, in advance, for any insights you might be able to provide.

Sincerely,

I'd like to have (2) 100W solar panels on the roof of a van. Is there a simple solution to have (2) extra 100 W panels to plug in when parked? Would the charge controller just need to be sized for 400W? Is there any kind of simple disconnect system available to add the 200 W in series to the panels?

Dear people

I am preparing project for my master degree, and my subject is off-grid solar powered electric vehicle charger. I need your help to check my calculations. I am bulding 9kWh solar system which will aproximetly produce 54.23kW daily. This calculation is done with average daily sun hours 6.3h with Victron solar panel mono 360W (working with 85% of their max). I need to install 28 panells 7 in series and 4 in parallel directions. Each panell is producing 1.9kW daily. 28 panell produce 8.56 KW per hour. Can I put my system to work on 48V, if solar pannel max. power V is 38.4V ? and my batteries are working on 25.6V ? Second question is choosing right charge controller. SmartSolar MPPT charge controller 250/100 can handle 100A and 250V. If I connect my 28 panells in way that I described (7 in series and 4 in parallel) how many charge controllers I need to handle all this power from solar panells ?(With my calculations that system require 2 * 250/100 MPPT charge controllers). And my DC load is going for Level 2 EV charging with 7.7kWh and rest DC current for Lithium Iron Phosphate batteries charging through quattro hybrid inverter/charger. Thank you very much.

Kind regards

I would just like to check the compatibility of the following products.

Can the Light dimming output or some other means used so a SmartSolar MPPT 75/10 can control a light using the time of day functions, and independently switch off a load (and the light) based on battery voltage? Is there another simple solution to this issue? Or is two SmartSolar MPPT 75/10s one controlling the light and the other the other loads the best solution?

hi there, i am new to this forum and also a PV beginner, so my questions might sound silly, apologies.

two things:

1. i have a 75/15 mppt installed combined with 2 50w westech panels

panel specs:

how many more panels can i connect in parallel? as far as i can understand, i need to add the short circuit current figures and make sure that total amps don't exceed 15 amps.

2. i want to deliver ~15 amps 30-35 meters away (100-114 feet) from the battery bank. a dc cable calculator i found online, suggests that an AWG 00 (~9mm diameter) cable should be used. has anyone done anything similar?any suggestions?

thank you all in advance for your answers

First off, let me clearly state that I'm a total moron when it comes to matters of electricity and electronics. Perhaps I should also mention that all the installations I'm about to refer to were done by Victron accredited installers. Historically, about 4 years ago, I had a 12/1600/70 inverter installed in my house to cover daily electricity cuts of up to 5 hours, and this worked perfectly for the appliances I wanted to keep running during those power cuts. Of late, however we are now experiencing power outages for 18 hours daily, so I decided I needed a solar solution as back-up to keep the 2 X 12v 200Ah batteries charged during daylight hours. This was done 2 days ago, but according to the battery monitor readings, the reserves keep dropping, which, to my addled brain indicates that the solar panels (3 X 265W) are not charging the batteries? My question is this: Is there a possibility that the MPPT 100/50 charge controller isn't doing its job, and if it is, why doesn't the battery monitor indicate an increase in storage levels?

Good day, I just lost the"connection" between the 150/70 CC and the Color control ? Suddenly.

The Color control shows "not connected" for the Charge Controler .

Checked the cables and they seem OK.

Checked to "see" the CC with bluetooth and I do see it there .

Any idea what can have gone wrong ?

Thanks

Hi all. Is there any way one can get basic information from a Bluetooth enabled Victron devices through Windows and its embedded Bluetooth?

We are making use of the BlueSolar MPPT 100/15 charge controller.

Hello,

I have recently purchased the Victron Smartsolar MPPT 100/15 15A 12V 24V Solar Charge Controller. I use this to operate the solar panel in my camper to charge the 2nd battery. My question is, if I can also attach my 1st battery (starter battery) at the outputs LOAD. If I understand correctly, this output is only energized when there is enough or excess energy, right?

Can you help me?

Cheers Boris

If I use a Victron Color control with a BMV and 2 Victron Solar Controllers + possibly 2 AC Victron chargers, will the chargers / controllers get confused, or are they synched to charge together? If they are, which device manages this - the BMV or the Color Control?

I have an external system that ties into my Victron system via a Modbus TCP connection to my CCGX. My need is to refine some tuning parameters in the external system. To do this I need to control the PV voltage and amperage inputs to my Smart Solar 150/45 controller wired to a 48V battery bank. I will do this by removing the PV Panel connections and using the Power Supply instead.

Testing output from the Bench Power Supply will range from 60-75V and 0-33A, not to exceed 1200W total output power.

Are there any risks to the charge controller during this test scenario?

Just want to make sure I don't fry something.

Thanks,
Pat

I have 2 x 330 watt panasonic HIT solar panels with a maximum 50 volts fitted to a narrowboat which is powered by a 48 volt electric motor. I have 2 banks of 48v gel batteries with 230ah from each. I will be looking to move to lithium in the future when the prices drop. Looking for advise on the most suitable charge controller

I currently have a 205W Kyocera VPm 26.6V IpMax 7.71. The Victron sizing calculator says 100/15 controller is what I should use. At some point in the future I would like to add another module to bring my system up to 400W and at that point I should be using a 100/20 controller according to the calculator. If I go with a 100/20 controller how much of an efficiency hit will I take using my one panel? I seem to recall max efficiency of a controller is when the panel sizing produces power towards the max end of the controller. I am currently running 12V with 180Ah from 2 AGM Trojan Batteries.

Hi
Can I connect 300KWHr 48 V LiFePO4 Battery bank to 16 units of Smart Solar 200-48 all in parallel to charge the bank from 90KWp of solar panel? how this can be connected to any XXGX? The inverter connected to the Battery Bank will.be 3XQuattro8000

I am considering changing 24V to 48V multiplus, but considering the Multiplus II. Is this compatible with the blue nova LifeP04 lithium batteries?

Also, is it compatible with the blue solar charger controller?

Hi, I have a 12v 45Ah AGM starter and a 12v 110Ah AGM cycle battery connected to my Blue Smart IP22 (3 outputs). The starter battery is always more or less full, but the cycle battery sometimes will go down to about 60% SOC. If I then connect shore power to the charger, it looks like it switches into float way too early, because of the already full starter battery and my BMV only shows float voltage for my cycle battery. So I assume I will not get charged properly, because float voltage is much lower than the needed abs voltage.

Or do I miss something?
