Question & Answer
Do these HUAWEI Optimizers come directly from Huawei?
What is the difference between Huawei optimizer SUN2000-450W-P2 and SUN2000-450W-P?
Does the current price of the Huawei optimizer 450W include tax?
How to determine the correct polarity of PV strings optimized with the optimizer Huawei Optimizer 450W?
What is the difference between a fully optimized system and a partially optimized system with HUAWEI optimizer 450?
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?
What is the minimum number of DC Optimizer Huawei per string 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?
How do I create a physical layout of my PV system with power optimizers Huawei PV Optimizer 450W?
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?
Power optimizers SUN2000-450W-P2 are not recognized.
Huawei PV Optimizer 450W does not work.
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.
The optimizers arrived in their original packaging. In the meantime they have been installed.
However, the facility is not yet operational.
We thank you for your kind comments and wish you a lot of fun with optimizer!
priced right, uncomplicated delivery to Austria
...ordered 14x in the last 2 days, first 5, then another 10, because meil Solateur somehow can't get to it at the moment. From the order to the delivery everything was great, after placing the order 3-4 days and the goods were there by DHL.
If everyone were like that, keep it up!
Not installed yet, hope in about 2 weeks, then I'll know if they work too :-P
Jokes aside, the only thing that surprised me at first was the packaging, all together in a box without being individually packed, but I'm also a layman and don't know whether Huawei even packed them individually ex works become. Otherwise everything is great!
In short, everything is fine, I'll be back!
About the packaging - Usually Huawei Optimizer comes in a box of 20, we will give you the original box if you ordered more than 10; And we will repack and resend the package if you ordered less than 10 because the original box is not enough...
for the optpmation of my phptovoltaic system, i smoked and ordered the huawei optimizer, unfortunately not yet installed
Cheap, affordable and fast delivery. I like that very much.
