Question & Answer

Do these HUAWEI Optimizers come directly from Huawei?

Mini Power is one of Huawei's official distributors in Europe. We promise that all our products are original Huawei products.

What is the difference between Huawei optimizer SUN2000-450W-P2 and SUN2000-450W-P?

The technical specifications of input and output between SUN2000-450W-P and SUN2000-450W-P2 are different, and the inverter models supported by each optimizer model are as follows:


Maximum power of the PV modules: 472,5w
Maximum input voltage: 80V
MPPT voltage range: 10-80V
Maximum short circuit current: 14,5A
Maximum output current: 15A


Maximum power of the PV modules: 450w 
Maximum input voltage: 80V
MPPT voltage range: 8-80V
Maximum short circuit current: 13A
Maximum output current: 15A

Does the current price of the Huawei optimizer 450W include tax?

The price of Huawei optimizer 450w is according to the German annual tax law 0% VAT 

Prices in other countries are calculated according to local tax rates.

How to determine the correct polarity of PV strings optimized with the optimizer Huawei Optimizer 450W?

In order to be able to determine the correct polarity (PV+; PV-), a string resistance or impedance measurement must be carried out.

The procedure is described in the enclosed operating instructions.

What is the difference between a fully optimized system and a partially optimized system with HUAWEI optimizer 450?

Fully optimized system:
each PV module has a power optimizer

Partly optimized system:
only individual PV modules have a power optimizer (e.g. shading, different alignment, etc.)

What is the minimum number of DC Optimizer Huawei per string in a partially optimized system?

The minimum number of SUN2000-450W-P power optimizers in a partially optimized system is one piece.

What is the minimum number of DC Optimizer Huawei per string in a fully optimized system?

As described in the data sheet, at least the following number of optimizers must be installed in a fully optimized system:
  •     3-10KTL-M1, 12-13KTL-M2: 6x SUN2000-450W-P
  •     2-6KTL-L1: 4x SUN2000-450W-P

Are Huawei Optimizers compatible with Smartlogger 3000?


The Smartlogger3000 cannot currently communicate with the performance optimizers.

How do I create a physical layout of my PV system with power optimizers Huawei PV Optimizer 450W?

A physical layout can be created by pasting, photographing and then uploading the included physical template layout to the FusionSolar portal.

A physical layout can also be created manually in the FusionSolar Monitoring Portal.

How quickly do Huawei optimizers turn off once the AC side is turned off?

The optimizers switch off within 0,5s as soon as the AC side is switched off.

Power optimizers SUN2000-450W-P2 are not recognized.

There is either a problem with your string, in the form of PV plugs that are not plugged together properly, or the inverter requires an MBUS update.
The MBUS update can be installed in the FusionSolar commissioning app at:

update devices
MBUS update

If the optimizers are still not found, please contact Huawei Support. Please also make sure that your inverter is suitable for optimisers.

The following inverters are compatible with the SUN2000-450W-P power optimizers:


Huawei PV Optimizer 450W does not work.

Please make sure there is no reverse polarity of the strands.

In order to determine the correct polarity reversal of optimized strands, a resistance or impedance measurement must be carried out. To do this, the resistance must be measured in both directions.

The measuring direction with the higher measured resistance is automatically the correct reverse polarity (+ pole from the measuring device = PV+ on the inverter).

Each 450W-P optimizer has an internal resistance of 1kOhm (+-10%). As an example, 10kOhm (+-10%) is measured in a string with 10 optimizers.


Reverse polarity of a PV string on the inverter means that the optimizers are not activated. Alarms with ID 2011 and/or 2012 are most likely to be displayed. Please correct the plug-in direction.

Pascal Schmitz
I had to update it first for everything to work

Except for a little delay in delivery, everything was great
After an update for the optimizer, the system runs great

Michael A.
I am very pleased

Delivered within a week. Connection is plug-and-play. The devices are automatically recognized and must be updated to the same version - the WR does this itself. The WR is then restarted and the system runs. I'm completely satisfied, price/performance is right!
