Function of the backup box Huawei

The Backup Box Huawei is used in PV systems on residential building roofs to switch the inverters to grid-connected or grid-decoupled status. Should the utility grid fail, the Huawei Backup Box switches the inverter to grid-decoupled status and supplies power in emergency mode. As soon as the power supply is working again, the Huawei Backup Box automatically switches the status again.

1A quality, fast delivery, highly recommended. Everything's fine. Thank you

Bad sellers

Unfriendly seller claims that I still have to pay VAT. You have to pay and end the conversation. Afterwards, PayPal claimed that I had not said my name and that this had caused misunderstandings.


You didn't tell us your name when you called, we sell 4-5 backup boxes a day and our staff confused you with other customers.

Our staff mistook you for other customers and the product was delivered on time after your payment.

Best regards
Mini Power

Reliable dealer

My ordered B1 box was delivered immediately. My questions were answered promptly.
The installation will only take place in a few weeks, so I can't write much about the B1 box.
I will gladly order from again

Super fast delivery, super reliable

I am glad to have found this seller.
I ordered exactly this back-up box from another supplier 6 months ago. Unfortunately, I am always put off that this box is not available at the moment. The only fatal thing is that I have already paid (2.295 euros + sales tax). Now I will consult my lawyer......
