Regolatore di carica solare MPPT da 10 A, 10 Amp 12 Volt, regolatore solare intelligente con display digitale LCD, ricarica SOC per batteria da 12 Volt

Der Laderegler ansich funktioniert gut, ich habe mich leider für die Variante mit steckverbinder entschieden (Anderson Stecker). Der mitgelieferte Batterie Anschluss ist mit rund 15cm viel zu kurz, hier wäre es besser 2 paar roh stecker mitzuliefern welche dann selber gecrimpt werden mit passenden Kabeln.Leider weist der Schaltanschluss bei meinem modell einen wackel Kontakt auf welchen ich nur durch fixierung des Kabels beheben konnte. Ich würde deshalb vom Modell mit diesen Steckern abraten und lieber das Modell mit schraubanschlüssen nehmen.

Guten Tag. Der PowMr. 60A MPPT Laderegler funktionierte ca.4 Wochen einbahnfrei. Anschießendfiel der LCD Bildschirm aus und der Regler war funktionslos. PV Eingangsspannung betrug max.130V.Batteriespannung 48.Bitte um eine baldige AntwortMit freundlichen GrüßenPeter Noetzel.

Da der "PowMr"-Solar-Laderegler effektiv, zuverlässig, günstig & auch wasserdicht ist, habe ich mir sogar ein "Backup-Exemplar" zugelegt ! Beide Teile haben ihre Funktion mehrfach im strömenden Regen, aber auch in "praller" Sonneneinstrahlung unter Beweis gestellt & mit "bravour" bestanden ! Sie haben dabei, via 50W-Panele, einen 12V / 100 Ah LiFePO4-Akku geladen & dadurch, während ca. 3-stündiger (30A-E-Motor-) Bootsfahrt & idealer Sonnen-Einstrahlung, für ca. 30-45 Minuten mehr Reichweite gesorgt ! Empfehlenswert !

Das Ladeteil ist praktisch, weil es direkt die richtigen Stecker hat, kompakt gebaut ist.Aber es lädt meine 100Ah LiFePo nicht zu 100 % auf - bei 13,2 bis 13,3 V ist Schluss, mein Votronic MPP 165 macht den Akku bis auf 13,4 V voll.Aber dennoch - ein gelungener Kompromiß aus Preis, Kompaktheit und Qualität.

I wanted a basic and efficient low cost MPPT controller to go with a 100W portable solar panel used to charge a 105Ah battery whilst camping. Running a portable fridge/freezer can take more power than a 100W panel can supply but should help extend use to a few days in good weather. I needed all the power available so MPPT was preferred but did not want to pay over £100 for something left out on a campsite and possibly in damp conditions. This unit at less than £40, small and rated to IP45 water resistance seemed ideal. It also does not waste power by having a large display, additional solar power output and 5v charging points. I use the battery to connect any 5v converters when I need them but they are not connected all the time taking power.How does the MPPT perform?There are some very cheap controllers claiming to be MPPT but reviews say they are not. I was a little skeptical that that might apply to this unit as it was cheaper than most but I am glad to say it does work well. It is possible to buy chargers which step up voltage for a few pounds and this is the basis of an MPPT controller with some smarts to dynamically find the "tracking" point. The hardware should not be as expensive if development costs can be coverred by volume sales. So this unit at 10A rating is feasible for the price charged.To test I used 3 digital multi-meters to measure both input and output current as well as the important input "tracking" voltage. The dispay readings of the output on the controller were checked and were found to be accurate, so I used the output voltage on the display. The current is only reported to 1 decimal digit so I used the multi-meter to measure the output more accurately. It is important when testing that the battery being charged is able to take the full output and is not being limited by the controller to prevent over charging. This is why the output voltage needs to be checked. At all times the output current was greater than the input current showing that the controller does work in MPPT mode. The tracking point was seen to vary as the controller adapts to changing clouds and shadding; typically 16v in sun. The current gain was consitently between 8% and 18% (typically 15%) at all current levels (0.5 to 5.5A) which seems a fair result. Max. MPPT gains should occur in colder weather and when the battery has a lower charge/voltage. The current step up efficiency at 5A was around 98%. Lower efficiency was observed at less than 1A e.g. 90%. The stand by current with no solar was only a few tens of milli-amps so any drain if left connected at night would not be significant. Whist I could not determine if the tracking point was optimum and I don't have another make of MPPT controller to compare the max. current and voltage the panel should produce ie 17.9v and 5.6 (100W) where as the controller set the tacking volatge at 15.6v and 5.5A (86W) and when conditions changed slightly to15.9v and 5.34A (85W). This seems near optimum considering the efficiency of the panel and the predicted max solar power available for London for that time and date was around 80% to 90% of the power used to rate the panel i.e. 80 to 90W expected and 86W measuredPosible Negatives:The tracking point did vary and take a few seconds to settle. A more expensive MPPT might be faster and save a bit more power but the gain would be very small. The unit gets warm on full output so should be kept out of the sun and in shade. This might be a problem on a very hot day where temperatures inside a tent can be quite high. The unit does have a high temperature shut down and does tolerate a high temperature. This is something to watch and will update the review if a problem is found. The max current is suitable for panels upto 150W which is ideal for a portable application but would require a purchase of another controller if 200 to 300W was required. However, this would double the cost and still be a similar price to other units rated at 20A. Also another MPPT would set the tracking point to match the second panel which would be better than one contoller trying to match 2 panels.
