This is a really hard review. The product was good however the customer service sucked. About the best thing I can say is Vevor should not advertise "get it by" date unless they can deliver on that date. I had an issue that I needed the inverter basically overnight for a mechanical issue that needed immediate resolution. I ordered the device on Saturday the 31st of January, expecting a delivery date of 2/2 which is what was advertised. Mind you, I did not have any options on shipping, because of this I expect the vendor to select a shipping method that would get the product to me on time. I received the product 5 days later than the advertised date causing me to have to secure a another controller and install it. This cost me so much time that paying a couple of buck for shipping would have been a better way to go. Heck this box weighed about 3lbs and is very small, In fact I could ship this box with 2 day delivery for about $13 bucks and that is at retail. I am sure that Vevor could have done two day shipping for $3 or $4 bucks which I would have paid for if I had the option. I did get the new inverter installed on Sunday and it appears to work as advertised. My biggest issue is customer service making excuses for the slow shipment, telling me that they shipped it on time. This is not an acceptable excuse as Vevor gave no option on shipping. This box went all over the western US going from Chicago, to Colorado to Los Angeles to San Francisco then to Sacramento. While I am all for site seeing, not for a package that was advertised "get it by Feb 2"

Not work properly

Bonjour. Je n'ai pas fait attention que c'était un produit chinois et document en anglais. Ou es ce que je peux récupérer la facture et sa garantie. installateur initial absent, je recherche instruction en français. Merci de votre réponse Bernard TETARD

Para um variador de 4CV cuja cablagem será no mínimo 4mm2 os bornes não suportam esta secção de cabos

No lo pone en ninguna parte, quizá mi error fue asumir por omisión que trifásico, como estamos en la unión europea, se refería a 380V, pero no... Solo funciona a 220v en bifásica o trifásica...

Ook hierboven is een deel van de sterbeoordeling nog niet correct, wordt vervolgd, de omvormer is op 3 fase input aangesloten op de aansluitingen L1, L2 en L3 en circa 5 tellen na inschakelen van spanning een doffe klap, wat rook uit de inverter en uiteindelijk na demontage afkomstig van een condensator welke in het apparaat ontploft is, een soortgelijke review had ik hier al eerder gelezen en dacht toen van zal wel een fabrieksfoutje geweest zijn echter nu gebeurt mij dit ook, ik moet verder en heb voor nood een andere goedkopere inverter gekocht waarvan de input aansluiting nu alleen op 220 volt is.

Bonjour, je l'ai branché et il a fondu, je ne vous en ai rien dis car vous m'auriez répondu que je m'était trompé dans le raccordement. bonne journée.

I have been trying to connect tech support for so i can connect unit to my cnc. I have submitted several "contact us" notices.

Between the 3 phases it only allows to get maximum 220V so it is a device for 3x110-120V. It is NOT meant for real 3x220V (380V) or 3x230V (400V). It do NOT match with the European voltage standards, despite the customer support statement. After the confirmation of the customer support, I have tried to connect that to 3x230V and it exploded. Overvoltage protection reach for only +15%.

Unable to purchase from this site anymore. Cannot specify shipping unable to use Fedex. This is a problem because customer service says ( I cannot help you with that) I thought that what customer service was for
