ich habe ein netzparalleles ESS mit Multiplus-II, Pylontech-Speicher und EM24.
Eine Phase des Hauses ist am AC-OUT1 angeschlossen. Meine PV-Wechselrichter sind lediglich am Hausnetz, und nicht am AC-OUT eingebunden. Der Überschuss der PV Anlage wird über EEG ins Netz eingespeist.
Soweit, so gut.
Nun habe ich noch ein wenig Dachfläche übrig und überlege, ob und wie ich das nutzen könnte, die EEG-Anlage will und darf ich dazu nicht verändern.
Ich dachte daran, ein paar Module mit einem Bluesolar 150/35 DC-Seitig anzuschließen.
Diese Anlage soll anmeldefrei bleiben. Geht das irgendwie? Kann verhindert werden, dass der Überschuss eingespeist wird? Wenn Nulleinspeisung möglich ist, bezieht sich das dann hausseitig über das saldierend messende EM24 oder nur auf die am AC-Out angeschlossene Phase?
Danke schonmal für die Tipps.
Instruction manual for Manual for BlueSolar PWM Charge Controller – LCD - USB shows on page 2 the warning:
BlueSolar Charge Controller is only suitable for regulating solar modules.
Never connect another charging source to the charge BlueSolar Charge
while the user manual Manual BlueSolar PWM-Light 48V Charge Controller does not contain this warning.
What happens if we connect a 80V battery instead of solar panels to the input ? Possibly the reverse polarity protection will blow in case of accidental wrong connection but shouldnt it start charging any battery with voltages 24/48V ?
I recently bought a BlueSolar PWM Charge Controller LCD&USB 12/24-5. Now, I'm using it with a 20 Wp solar panel and a 12V/24Ah VRLA battery. It's going well. But I have a question.
Sometime, on the LCD display, the left arrow, the one between the solar panel and the battery (also called "charging symbol" in the manual) is blinking. Moreover, there seems to be two different blinking speeds. I didn't found any explanation. So, what does the blinking of the charging arrow means?
I built a pontoon boat with a 48V outboard and the SLAs were not getting the job done so we are changing to lithium. I am adding a cobbled together solar charging system and was planning to mount the BlueSolar PWM 48V 30A inside the console. Will this work? If not, will a small daylight source (a hole) work?
Hello. I've connected 2 new 95Ah AGM batteries and 12V 100W panel to Victron PWM LCD duo regulator (20A). When I connect everything in correct sequence PV voltage shows around 13,2 V and batteries are being charged at the same voltage (1,5 - 2A). When I messure voltage directly on + and - cable from panel I get reading around 20V. Regulator program iz set to B01 (AGM). I have even tried another regulator and same thing happend. Is this ok? Sky is celar and sun is high. Batteries where new and almost full. Thank you very much.
I'm have a 30 amp 12 v pwm blue solar charge controller that is new. Will be charging well. Come back an hour later and less than half charge. Reconfigure from lifepo4 to gel and immediately recovers for an hour or two the drops again. Reconfigure back or any battery alternative and full amperage recovered. Im using 2x 160 w 36 cell panels in parallel with 120 lifepo4 battery with 40 amp bms. System works fine with cheap pwm from china not designed for lifepo4. Its as if system goes into absorption mode even on lifepo4 after a few hours
Any advice please
When new, this charger charged continuously in full or low sunlight, through the appropriate stages until it reached float.
Now 2 years later, if the battery is only slightly discharged but I have full sun it will charge as expected. If a cloud then covers the sun, instead of still charging continuously right when I need all the power I can get, the charge disconnects and reconnects about once per second. I can see this on an ammeter measuring the current from the solar panel. Hence I am only getting about half the charge that is available.
Why does the charger ration the power to the battery right when I need it to put all the possible charge through? Can I change something to make it charge continuously without have to bypass the charge controller? I have no load connections in use so the charger is simply there to charge the battery.
I have a BlueSolar PWM Charge Controller – LCD - USB and a generic PWM charing the same LiFEPO battery with build in BMS (LionTron).
Very often when the sun shines, the BlueSolar 's arrow between the Solar Panel icon and Battery starts blinking fast. ( not the slow float blinking, but fast like 4x per second ). The charge current is also low (but not zero).
When I reset the PWM ( disconnect solar panel and battery / Or switch between B4 and B5 and back, so PWM reboots ) the blinking stops and the PWM charges maximum current.
I wonder why it is doing that. There is no mention about fast blinking in the manual. I asked the question to Victron through my reseller, but that did not get me an answer.
Does anybody know what this blinking means ?
Is the USB powered by just the solar or the battery too, if it is battery is it via Battery 1, then Battery 2? Does it cut off at a certain voltage? I want to hook a fan via USB up to the controller but I don't want it to kill my batteries if left unattended for longer periods of time.
Hi. I have just setted up a system with BlueSolar MPPT 150/70 and two Multi C 2000 @ 24v with 4x445 panels (1780w) connected with a 600h SOPZ bank.
I started it up and saw the BlueSolar bringing in ~200W, since the batteries where almost charged by the Multis via the grid.
I then put some load on the inverter, up to 1.5Kw and I noticed the BlueSolar was not producing more than ~420w, therefore drawing rest from batteries. At that time the panel voltage was at 92V , o a summer sunny noon.
Is there something wrong in the setup , do I need to do any further configuration?
leider komm ich nicht ganz klar welchen Laderegler ich auswählen soll oder muss. Ich dachte das mir der 100/20 reicht, da ich aber gelesen habe das der kurzschlussstrom 20A nicht überschreiten darf muss ich wohl den 150/35 nehemen. Oder habe ich jetzt was übersehen. Meine Konfiguration ist 4x370w Panels welche an einem Balkon montiert sind und zwei in reihe und dann paralell angeschlossen sind, mit diesen würde ich gerne jetzt einen 48v Pylontech Akku landen. Die Werte des Panels Voc 44,4 Isc 10,5A (Vmpp 37,5 / Impp 9,9A) Das zusammen würde ja dann Voc 88,8 und Isc 21A machen. Deshalb die Frag. Danke Ach ja mehr wie 220w bekomm ich nicht pro Panel im peak.
I have done a search but can't find an answer relevant.
I have a BlueSolar Charge Controller-LCD-USB 12V-20A.
It has started showing a flashing error message L5C (or maybe LSC) as shown in the image below. "L" in the manual relates to the output load and sunset etc which doesn't appear relevant.
It doesn't appear in the error codes listed in the manual and I can't see anything useful on Google. It also doesn't appear to have any issues with the operation as it takes charge from the panels, and the loads which come via this unit.
Thanks for any help which can be offered.
1) Would it be possible to have two different types of batteries with Bluesolar DUO? For example 12V LiFePO4 and 12V AGM battery or then two AGM batteries with different sizes.
2) Also is there any output for battery cut-off at low voltage on Bluesolar DUO? Of course I want to keep my batteries without getting to too low voltage... Even a separate relay would be ok, but I would not like to build the logic for that (Battery Protect device is too expensive also).
3) How about two batteries of same type & capacity (Li, AGM or so), but having one completely empty and other one full. Example: You connect the full or empty battery on bank 2, while the othe one in bank 1 is in different state, what happens?
I have the following setup in tests before installing it on a sailboat with some more Victron equipment:
We have the system working but with some important configurations to be done and for which I would like your help:
Easy solar was working perfectly, the 150/70 working perfectly too.
Then no PV charge at all.
Solar voltage is 101.13V
Solar Current is 0.0A
Battery is 51.03V
Battery Current is 0.0A
I’ve contacted the company from whom I purchased all the kit.
Their guy took a look at my Victron Connect and he can’t find any reason why it isn’t charging!!!!
He’s wanting me to remove the Blue solar and sent it to be independently tested.
Any help would be great fully received.
Thank you in advance
