I buy from Anern company 4000W ON/OFF grid solar system, 10pcs 400W anern solar panels, 6kW anern inveter, 2pcs 4,8kW anern lithium batteries.
Everything could be connected succesfully.
Problem is that at maximum intensity of sunlight, the system could deliver only at peak 2kW from solar panels (half).
The another problem is that inverter can charge the lithium batteries only at 10Amperes. So it took two sunny days without another electricity consumption to fully charge the batteries.
Their sales support will comunicate with you without any knowledge about solar stuff.
And they will stop to communicate with you.

Anern produce useless chinese equipment.
Can't recommend Anern industry.
Please look for another serious producer.

Update 31.05.2023 by Jozef K.:
It's even worse than we thought.
The solar panels from Anern lowering the produced power day by day.
The panels was installed in Nov/2022 and now is May/2023, after half year the 10pcs 400W panels producing only 1000W during sunny day and pointed directly at the sun.
The sales manager said that it caused some technical problem at their producing line, so the panels are defective from production.
Sales manager said that they can replace only if we make new order. (New order of useless stuff)
This was the worst investment we ever made.
