1 hét után 8 as és 3 as hibakóddal meghalt. Több mint 1 hónap után garanciában megküldték a teljes belsejét . Saját beszereléssel. A kissebbik testvére(3,5kw) tökéletes de a 6 kw-os sajnos nem egyező minőség. Erősebben megnézve mintha két külön cég gyártaná.

I'm just not happy that it is not a 120 volt so I can't use it in the United States. I wasted $313. I'm sure it's a good product for Europe because I always had good luck with VEVOR products.

Dommage que l'application ne marche pas.

Great product

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
