Nice solid inverter, packed well and quickly delivered. Beware of vertical installation. I connected the fans to an external dc power source and they pull the air from then inside to the outside. It is easy to reverse the fans if you like to install it vertically but with the fans at the bottom so the hot air is going upwards. Recommended product and seller.

The inverter itself is twice the appearance and weight of the heavier and the harder than the analogues, the quality is excellent, the packaging is also excellent. Now the disadvantages: 1. I ordered 2 pieces at different times, the first one got stuck in Romania and disappeared, after 3 months I opened a dispute and returned the money, ordered a second one, waited for 3. 5 months, the longest delivery in 8 years of work with Ali, so if you are not ready to wait and risk time, order from another seller. I ordered an 48-volt inverter, I thought they would have all types of connector and USB, when I ordered it, it was not written in the product card that these outputs are only available for the 12-volt version, so be careful. I opened a dispute по этому поводу, but the seller only returned $5. And I have already added information to the description. The product is generally good, but while he was driving the need for it has disappeared. In fact, half a year has passed since the first inverter was ordered and the goods were received :) I recommend the product, I do not recommend the seller because he probably sends it by courier who comes on foot from China.

The order arrived very quickly, in ten days the inverter was already in Ukraine, Ukr Post. It was not possible to try it, but it seems a great thing, well assembled and difficult. As soon as I check the performance (battery will come), I will add my feedback right away, I hope everything will be fine. The manufacturer and seller were responsible, always were in touch and answered all questions immediately. For now, Thank you very much and I recommend cooperation.

The order was placed on November 6th, the inverter was received only on February 26th. Before ordering from the seller, I was interested in whether any changes occurred in this model or its modification, which the seller answered. No, and the model remained the same as it was. Having received the inverter and opened the cover, I saw that the filling was completely different from the one that was in my old inverter, namely the already simplified one. The new inverter includes airflow of the fans not due to heating, but due to load. Somewhere after 800W the fans turn on and get slightly stressed when running. The old version of the inverter quietly holds 1 kW And time by time the fans blow it down and turn off; the new version blows constantly. Personally, I don’t recommend this inverter now.

Excellent device. Very high quality assembly, appearance. The branded packaging is also happy, which confirms the quality. The sine wave is perfect and holds the load perfectly. many protective functions. It looks like the device of this company is one of the best, which is true.
