Klantbeoordelingen voor VEVOR hybride zonne-omvormer, 6 kW, alles-in-één omvormer met zuivere sinusgolf, 48 V DC naar 220/230 V AC, met geïntegreerde 120 A MPPT zonne-laadregelaar, voor loodzuur-lithiumbatterijen in off-grid systemen.

Mis en fonction il y a 1 mois. La connexion WIFI ne fonctionne plus.

Modes of operation are hard to follow, in consistent terminology. Needs a better translation.

It has a really good price which comes with some drawbacks and I thought the only drawback are the only mentioned in product description but it turns out, it isn't. -It has a relatively huge no load consumption, despite the 35 W mentioned on the website, it's 61-62 W when the inverter is turned on, if You turn on the power output and it turns on automatically because of the solar input, it's around 52W which is 37.5 kW per month, if you let turned on the output it's 44.6 kW per month which in some cases more than the winter months production. -The voltage measurements are quite accurate but this isn't true for the current measurements and there is no option to do some calibration unfortunately. -The data forwarded to the servers/application are in some case quite confusing since I made continuous measurements with calibrated clamp meter and in some cases I find out that some part of the datas are forwarded in different time, thus it's confusing when the solar production is about the same as the charging power (like there would be no loss), and in some cases it's more than doube (like there will be less than 50% efficiency) -Unfortunately due to high base consumption, at smaller amp production (due to novermber, december) the mean efficiency calculated by exact measurements was 53%, with over 500W production, it reaches 82% which is far away from the claimed 94 % efficiency. As I will have more sunshine and bigger solar production, I will update this review with exact datas, I hope it will come closer to the claimed one. -As some positive, it looks good, it works and it can give the power noted in the specifications. It would been nice to have some software updates which would allow amp measurement calibration, reduction of the baseline consumption for example by reducing the speed or turning off the fans since in 10 degree when there is only 1-2 hundreds of watt production I don't think that it needs to go continuously and also some consumption reduction programs for example during the night, if there is no load on the output and no solar production, it's not efficient that all of the MPPT and outputs are turned on consuming 62 W or some other automations that would reduce the base consumption.

Ser greit ut men ikke fått tilbake meldingen ang sinus, må agregat ha ren sinus for at innverteren ska lade🤔🤔🤔

Product arrived on time quality packaging seems to be quality device how ever they do not specify that these are 220 230v single phase they will not work with our split phase systems in the USA even with a step down converter power plulses and spikes burnt up dvd player fan and some led lights

Il manuale dice di usare un cavo rj45 per il protocollo bms ma non è incluso. Ho adattato uno dei miei cavi seguendo i pin del manuale ma non riesce a leggere le batterie che ho già installate e pertanto l inverter per me non è utilizzabile. Ho chiesto il reso anche perché assistenza non è facile riceverla. Spenderò una cosa in più e tornerò al vecchio marchio.

El inversor ha dejado de cargar a la Baterías de Litio que se han agotado, es una casa aislada, sin suministro eléctrico, el inversor enciende con un grupo electrógeno, pero no carga las baterías, ni con la placas solares ya que tienes salida con voltaje a amperaje correcto, tampoco con generador electrógeno, les envió la fotos que he tomado, les ruego me cambien el mismo o me den dirección de envió

the inverter was easy to set up but the APPs are a total joke. and near impossible to get working so this is the last thing i buy from VEVOR until they either include the software or make an APP that actually works, i wasted a day trying to get these useless apps working even with the help of Chat-gp and Ai could not get it to work and WHY WHY WHY does the writing in these bloody Chinese manuals have to be so tiny?! I needed to use a magnifying glass to read the overcomplicated setup and worst of all the so called "QR Code" on the side of the machine just leads you back to the VEVOR Shopping site no apps there either what a truly awful experience!

I was very happy with the original operation for the first week. The inverter started having power supply issues and buzzing noise. I am currently waiting for support team to hopefully resolve my issues. If the inverter can continue to work as it originally did I would be very happy with the purchase. This will be a good test for me as to how support team helps with this issue and how happy I am with Vevor going into the future.

Das Gerät ist im Großen und Ganzen gut. Leider ist die Einstellung des Geräts über das Display nicht so einfach. Es gibt leider keine App oder die Möglichkeit, das Gerät über den Webbrowser zu steuern. Das würde natürlich alles vereinfachen und eine bessere Übersicht verschaffen. Bei Garantiefällen ist die Wartezeit leider viel zu lang, bis der Support eine Lösung bereitstellt.
