The manual states "Always connect the batteries first, in order to allow the Controller to recognize system voltage"
This leads to the question, "What will happen if the solar panel is connected first?" There may be occasions, for example when a fuse to the battery is replaced, that the solar panel is already connected. Will the system fail and if so will it fail safe? What will be its behaviour?

Hi folks

I have a BlueSolar PWM (LCD) controller that has a blank screen and is not charging. It is connected to a 40 watt panel, and is used to keep the starting battery topped up on my camper when it is sitting for long periods.

On a sunny day, I meter 20+V at the controller input terminals, and 12.8V at the output-to-battery terminals. However, the screen is blank, and it is not charging the battery.

After only three years, has it died?

Hello I have solar panel connected to car battery through Pwm, everything works fine, but after I started engine with a bit low battery, on Pwm started blinking U 0.2v, which means voltage on usb output is only 0.2 volts. Normally it shows around 5 volts. It happened me once before and after a while it went back to normal, but now it always stays the same.

Pwm is working normally, only usb is not working.

I haven't found any relevant info on this, do you have any idea what can be causing this and how can it be restored?

P.S: I tried disconnecting the module, but didn't help.

Thank you

Bonjour,

Quelques questions concernant mon pwm victron 12v/5A

Ci-dessous l'installation :

• Régulateur BlueSolar PWM LCD-USB 12/24V-5A - configuration b04 (tension d'absorption 14,2v + batterie lithium).
• panneau victron mono 30 Wc (câble 6mm2, longueur 1 mètre).
• batterie victron lithium superpack 12,8V 20Ah 256Wh (câble 4mm2, longueur < 50 cm).
• victron BMV 700 (param 02 tension chargée = 14V, indice peukert = 1.05, efficacité de charge 99 %).

En condition d'ensoleillement optimale (inclinaison, orientation, midi solaire) on a :

La tension au niveau du panneau est de 17 V sans être raccordé et en étant raccordé au borne du pwm la tension est de 13 V.

La tension ne monte jamais à 14,2 V tension d'absorption prévue par la configuration b04.

L'intensité de charge ne dépasse pas 1,5 A en plein soleil (à midi solaire, soit 20 W max mesuré par le BMV).

Le pmw en charge ne dépasse pas la tension de 13.4 V.

Les tensions aux bornes PV et de la batterie sont toujours égales au niveau du pwm (environ 13 V).

Quand le PV est débranché la tension au niveau des bornes PV du pwm est de 1.1 V.

La tension au niveau des sorties USB est de 4.9 V

• Est-ce que tout ces tensions sont normales ?
• Est-ce que le calibrage de la tension du pwm n'est pas défectueux ?
• Est-ce que le BMV 700 a une action sur la charge / décharge de la batterie (pilotage) ?

merci

Hi, is it possible to connect the Victron-Energy BlueSolar MPPT 150 45 tr with the victron app? What is the difference to the one with the bluetooth sign on, Victron-Energy SmartSolar MPPT 150 45 ?

Hello everybody,

I'm interested in BlueSolar PWM Lade-Regler (DUO) LCD&USB and like to observe the amount of capacity going into the batteries.

Is there an option to integrate it in Cerbo GX which I have?

Thank you very much for your help

Jens

I'm curious if my PWM Light bluesolar (for 12v battery) charge controller is okay to stay connected with an autostart feature on the 32kva genset. Or should I keep the generator off until disconnecting the two solar panels before using the battery to start? Normally this setup is for a battery for camping, but the generator batteries usually are dead before I need the generator and tired of having to jumpstart from a vehicle.

I'm currently using the PWM on H (manual) setting, but if there is a recommendation of a different setting for my setup would appreciate hearing. Thank you

I'm running a BlueSolar pwm LCD-USB 10a controller in my bicycle trailer with a 30w panel and 8ah LiFePO4 battery, all new.

Battery was draining quickly in storage (only whilst connected to controller, alone it holds charge), thinking it must be a short in my circuitry and not a problem with a new Victron I disconnected all my circuits one by one until finally disconnecting load wires completely from the controller, but it still shows 0.5-0.6a load. Battery is connected directly to controller and to nothing else. All circuits are switched and connect to load terminals but even with both load terminals disconnected the controller still shows 0.5a constant draw, which stops if I deactivate the load output from controller.

Do I have a faulty unit? I read self consumption is 10mA in the manual. I feel like a half amp draw whilst load terminals are active but disconnected isn't right, and it renders my system unfit for purpose as my battery won't last long days with the extra draw of leaving load terminals active.

Any explanation or similar experiences? Thanks

Received two new BlueSolar MPPT 150/35 with handwritten permanent marks on back. Is this normal?

Hi, would this work?

1 PV array with feed cable going to a junction box where 2 Bluesolar Duos connect. The first duo goes to 2 lead acid batteries, the 2nd Duo goes to 2 Lifepo4 batteries. I could add diodes in the junction box if required.

In my boat I installed the PWM Duo with battery 1 being a lead acid starter battery and battery 2 a 100ah Lifepo4. Settings only allow selecting 1 battery type however. Is the product only designed to charge 2 batteries of the same type?

And if so, what would be the right solar charger for me given 12v and 200W solar?

System : Color Control GX, MultiPlus 48/5000/70-100,SmartSolar MPPT VE.Can 150/85 rev2

I want to connect a spare bluesolar mppt 150/85 with new panels for the east side, as my north-west generation only fully performs around 13:30.

Is it possible to connect and "old" bluesolar and smartsolar ve.can together on the same Color Control GX?

Thanks

I'd like to refresh some old 12v batteries with an equalization, I bought the PWM Pro for this purpose, but I see no way to launch it as I can do with, for example my TriStar MPTT where I just have a button to press.
This is not an ad for the Tristar, I love Victron products....

The software does not seem to allow this either (at least it's not explained in the software manual). I have a raspberry with a RS485 interface if there's any open-source documentation on the PWM-Pro COM protocol.

Hello

I have a had a BlueSolar 75/10 in my camper van (VW T4 Westfalia) for four years now, and up to now it has worked really well. Solar panel is 60w.

However, on a recent trip I was on a campsite - sunny day, had driven some distance, and on electric hookup - and I noticed the voltage display was flashing and reading 15.1v. Previously, in these circumstances the display would have registered float voltage (13.8v, occasionally 13.9v or rarely 14.0v). I was concerned about overcharging the battery so I disconnected the hook up, but the 15.1v soon returned. The battery itself wasn't warm, but I wasn't taking any chances, so I disconnected the Victron for the rest of the trip. No further problems (i.e. 13.8v/13.9v on hookup, lots of charge from the split charge relay), leading me to believe that the Victron could be faulty.

Now I've returned home, and the days are less sunny (and no hookup), I've reconnected the Victron and it's steadily building up (13.3v at the moment from 12.9v a couple of days ago).

Is there an issue with the Victron, or is the flashing 15.1v something I can ignore, as maybe the battery is absolutely at full charge and the Victron has cut out?

Grateful for any help/advice!
