charge controller compatibility

In order to gain more amps out of the a single Centaur charger, is it possible to simply attach all three output to a buss - and thereby gain 3 times the current output?

To clarify... I do not want to plug the display onto the controller but use connector to mount display remotely. Is this what VE.Direct to RS232 is used for?

My boat has BlueSolar MPPT 100/30 solar panel controller and AGM deep cycle batteries. I would like to replace the AGM batteries with LiPo batteries with the following characteristics:

Can I use this solar controller with the LiPo batteries, and if so, do I need to change the settings?

Based on the Victron battery compatibility page, the Pylontech Force-L1 battery has been tested and is compatible with the MultiPlus-II 48/5000/70-50.

I'm from South Africa and here we don't get the Pylontech variant of the Force-L1 but rather a KODAK re-branded Force-L1 battery. They are virtually identical in spec and appearance. The KODAK is just a different color but I'm not sure if the MultiPlus will recognize it as a Pylontech battery or if the KODAK runs a different firmware on the BMS.

Does anyone have experience / knowledge on whether the KODAK branded Force-L1 will be compatible with the MultiPlus?

After one or two minutes of use, the controller stops to send power to the instruments. If I disconnect the - of the battery, and reconnect even immediatly, it reworks for, again, one or two minutes.

I have tried to plug the battery direct, no problem, so it seems that's the controller which is in fault. Is it possible to fix it?

Thanks and regards,

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, 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

Hello all.

I want to add more charging capacity to my victron ESS system moslty for the winter/dull days.

(multiplus 48/5000/70, 4 x pylontech us2000 and 4kw solar Edge)

Looking at getting a 100/20-48v.

The choice of panels I have are

4x 285w 2series 2 parrel (voc39.3V isc 9.5A per panel)

2 x 325w in series. (voc40.7V isc 10.37A per panel)

2 x 375w in series. (voc47.75V isc 10A per panel)

They will be on a flat garage roof s/w facing so will not have max sunlight.

All check out on the victron calculator but with 4x285w showing Amber charge current of 20A

Im thinking 4 x 285w for most efficient in bad conditions, but some expert advice would be much aprociated.

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

I’m building an RV system using (6) 250w panels with the following specs:

Max Power: 226.92w

Vmpp: 21.052v

Imp: 11.01a

VOC: 24.34v

Isc: 11.75a

While researching for the appropriate Victron controller, I attempted to use the MPPT Calculator (Excel) to size the charge controller, but my panels don’t seem similar enough in specs to the Victron panels for inputs.

I plan to use MPPT 150/100 with the above panels (which I already have) in parallel and 12v. But now I’m confused as to whether the panels exceed the controller’s capability, and/or whether I should wire it differently in some combination of serial/parallel.

Can anyone verify this unit will work or recommend a better course of action or a different hardware configuration. Any help greatly appreciated.

BTW: I currently have a 12v battery bank using (4) Trojan T-145 6-Volt batteries. I realize this is small for the above, but plan to replace this after I install the above.

Connection to my 150/85 CAN MPPT controllers has always been flawless until I installed my new Cerbo yesterday. Does CAN connection to the Cerbo prevent Bluetooth connectivity? The Victron remote console shows solar charging correctly.

The Victron connect app shows one controller in grey and indicates it's already connected to another device. It's not. The other controller looks normal, but connection stalls at 20%.

I have shut down and restarted the Victron connect app. I have restarted my phone. I have un-paired and attempted to re-pair the controllers. The controllers will not re-pair.

Let's say a 12 V AGM battery bank is charged by a big, powerful but terribly inefficient "BULK" charger that runs for a limited time up to 14.4 V Absorption, but this charger wastes 50W when IDLE / Float, even when the battery current is less than 100 mA. The Bulk charger can be set to turn off at end of Absorption.

Could I use a Blue Smart IP65 (or IP22) set to Power Supply Mode at 13.5 V in parallel with the Bulk Charger, just to provide a more efficient Float stage?

Would the 14.4 V Absorption of the Bulk charger cause damage to the IP65 or IP22 set to 13.5V?

Thanks!

Hi all,

I am designing a custom solar system setup and want to be sure it will work.

Here's details on all components

Solar Panels - Two 12v panels at 115 W each (already owned)

Charge Controller - Victron BlueSolar MPPT 100/30

• 2 units at 500 Wh each = 1000Wh x 70% usable = 700Wh usable. These batteries are 60-70% usable capacity (I guess because BMS limits it?)

Inverter - Victron Phoenix 12V 500W

My goal is to disconnect the solar panels and connect the wall charger (powered by generator) on cloudy days. The reason I chose a 48v charger is because I will eventually get a 48v battery for an electric bike so I'd need it anyway. I calculate that I can plug this charger into the inverter to charge the bike battery from the Nissan Leaf batteries. What do you think my potential issues are? Thanks a ton!

Hello all,

I have a small panel (80W), sufficient for my boat.

I want to be able tu cut off both panel and charge controller ("regul"), but also prevent a wrong manipulation (that is to say; panel connected to charge controller but charge controller not connected to the battery.

I have plan to use 2 bipolar switch, wired like in this picture.

Well here only the "+" is shown, to have it clear, but the idea is to set 2 switch, one on the "+", and another on the "-".

Is there any issue to do it this way ?

Any risk when the charge controller is connected to the solar panel and the battery simultaneously ?

I am new to Victron and Solar in general. I just purchased a 250/100 charge controller and want to make absolutely sure I don't ruin my starter battery. I am using a Nissan Leaf Gen 1 14S setup at 48volts. I want to make sure I use the best charging profile for this, can someone give me some guidance from their setup?

Hello,

from the data sheet it looks as if the Victron BlueSolar MPPT 75/15 is identical to the 75/10 except that it costs approximately 10 EUR more but is capable of charging with 15A rather than 10A.

Is there any reason (except of the 10 EUR) not to choose the 75/15? For my purpose it would be overdimensioned as of now but I may choose to connect larger solar panels sometime in the future.

Best regards,
Daniel

Having difficulty figuring out what controller I will need for my solar power boat project. I’m hoping you can help me.

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.

I have a 2021 eclipse attitude rv that has (2) 210 watt solar panels roof mounted, with a Zamp Solar ZS-30A 30 Amp Digital PWM Solar Charge Controller. This trailer is new to me and have tried to do alot of research on solar/ chargers. I was looking at the victron 100/50. I am not sure if this is the correct choice, I am currently seeing 30 amps of charge rate but will not keep that up until the lifepo4 battery is charged, it will kick into float very early in my opinion. I also plan on adding (2) panels but not for a awhile. also what wiring changes will i have to do to the solar panels to use the victron charge controller? thanks for nay help

I recently installed the SmartSolar MPPT 150|100-Tr charge controller. I love it so far, and a huge selling point for me was being able to monitor the controller from an app and also export the data.

I have a few questions about this controller that'd I'd love help with:

1. How much data will the charge controller store? What kind of storage is inside it? I would obviously like to keep the data for the lifetime that i have it and want to make sure I don't loose any data
2. Is it possible to query the charge controller's data from some kind of API? I'm a developer and I'd love to be able to query the current stats of my charge controller for other projects I have. Is there some interface I can setup to do this from a local network?
3. The controller has a remote and relay output. I want to setup a tablet next to the charge controller and don't have any AC outlets in my electrical room. I obviously have a ton of DC connections, but I'd love to avoid setting up another breaker just to power a 3v 2a USB connection for my tablet. Can I use the Load Out of the charge controller to power a USB device and if so, how?
   
   Thanks in advance for any help, much appreciated. I'm really excited to be part of the victron community. I've been eyeing these systems for a while and really happy to be using them now.

I have an old Victron Phoenix 24v 3000w Inverter, with an old "generic" solar charge controller.

My old batteries have finally given up.

I want to replace them with something with a good lifespan and was thinking about the Lithium HE battery 24V 200Ah 5kWh

I THINK I need some fancy battery monitor in addition to the battery. Is there something specific I need to check on the old charge controller? (From Memory it had options for sealed, flood, and gel. Lithium didn't really exist when I bought it). If no good what would be a good controller (around 500w of Solar)

Thanks in advance

400Ah (2 x Renogy 12v Deep Cycle Batteries)

450 Watt Solar (3x150) - the most I can fit mounted on my van roof, I will NOT be expanding to more panels. https://www.amazon.com/gp/product/B07WV6P4BT/ref=ox_sc_act_title_3?smid=AV16HZDTPF1LD&psc=1

W/ Wirthco Battery Isolator adding power also

Hi. I have a VW T5 with a 12v leisure battery connected to vehicle battery via a 140A Sensitive Relay (Portable Power Technology).

I have fitted a 150W solar panel and SmartSolar controller MPPT 75/15 to the leisure battery. My problem is that the split charge relay constantly clicks and only stops when I use power from the leisure battery (turn lights or fridge on).

Is this a problem with the controller settings or the relay?

I just expanded an existing installation by adding a 250/85 to an existing system with 2 x 150/70 charge controllers . All wired up this afternoon, but the new charge controller is just sitting in float rather than charging as well. The old chargers are in absorb and the new addition goes straight to float, meaning the new array is not doing anything . Is there a fix for this ? One thought I had is the the 150/70s are using the adaptive charging ( which I cant change) and the new one I have set to fixed absorb time . The 250/85 didn't even run through its full absorb time before going to float

thanks in advance

Hi,

I have 2 loss-free diode bridges between the alternator and my 4 (1x start, 1x bow thruster, 1x winch, 2x service) batteries. The specific type is this one:

https://www.studer-innotec.com/media/document/0/mbi_series_user_manual_en.pdf

Can I connect an MTTP solar charger to the same + as the where the alternator is connected to?

I'd like to do so, so that all batteries get charged and not just the service battery.

All batteries are 'deep cycle 12v' batteries.

I tried to use the online calculators here and other and can't seem to get a output. Ive send emails technical support from my Solar Panel company with little help other than to try to sell me a complete system that I dont want or need.

Just want some friendly advice on Victron Solar Charge Controller for my situation.

550 Total Watts, hooked up in parallel (but could be convinced to switch to Serial)

I have the following:

(2) Go Power MODEL: GP-PV-190M
Output power 190 W
Rated current 9.3 A
Rated DC voltage 19.1 V
Open-circuit voltage 22.5 V

(1) Go Power MODEL: GP-PV-170M
Output power 170 W
Rated current 8.79 A
Rated DC voltage 19.3 V
Open-circuit voltage 22.8 V

Thank you for the assistance

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,
