Finally received it! It took a long time to ship, but the seller was attentive and answered my questions. Yesterday, 29.05, I received the WIFI module, and today the inverter. At home, I connected it to the network, it turned on and started working. Now the only issue is the battery life.

installed, works so far.

Good inverter and controller.
Switching from grid to battery is indeed near 20ms - can test with 230v led lights. Tried powering monitors and they can't tell the difference: no flicking, no lag. Have not tried beefy computer yet.

Only downside is +-40watt power draw to keep inverter active at all times, but that can drain the battery. Have not found an option to disable this... but can be managed with external contactors on grid/battery side

Overall looks to be good product and definitely for affordable price.

Tested model 2kva(1.6kw) 12v battery lfp
Will surely buy bigger model as i expand solar and battery!

The device is actually very good. This is already my second one, because the first one broke after a few months. The inputs for the battery cables are not secured! That destroyed the electronics.



But if you keep an eye on that, everything is fine. The fans are very loud. That's why installation in the basement or outside the house should be preferred.

I couldn't manage to connect to the WiFi, and I'm probably not the only one.

The only downside I have is that it operates at a slightly high temperature.
I had to add an additional fan.
the rest perfect.

Great inverter, 5 stars.

the inverter is in top condition, it arrived a little scratched but that doesn't bother me for its operation. For now, I've used a maximum of 1.5KW, the minimum V for the solar panel is 60V, so it's best to have 2 solar panels, if not the maximum.

They are very serious and quick in their work. I am very happy with their professionalism, I will surely continue buying here. Thank you very much for everything.

It arrived quickly and everything is correct, it's already working, I'm happy with the inverter (I recommend it).

Received it quite quickly. Didn't have to pay anything extra. The WiFi whistle came separately. So far everything is great. I'll keep checking.

The inverter was sent as ordered from Germany. I received it a week later. It works perfectly!

Can even operate solely on solar panels. I tested the load at 2 kilowatts, it works well. Excellent device.

Excellent seller, highly reliable!!!!!! Top-notch reliability

I had the old version of the 12v model, they are a bit delicate... anyway, this one works well, everything is ok installed, it's working well, satisfied to see how long it lasts... anyway, shipping wasn't very fast as it was declared 'local', good packaging, no damage, ok.

Good product does the job well very easy to install.

Works great, also fit for my airconditioner, so now on 100% solar with both heatpump and aircooling. .
