This is the result of my reseach last 3 weeks :
i was in contact with "Kingsley Lin" from https://supersolar.en.alibaba.com/?spm=a2700.12243818.104.22.168ce83e5fIAkhzz
but i have not yet purchased since i still have time for my solar project.The quotation was 715usd DDP to Germany wifi included...
I received last days some emails from different companies in Alibaba saying that they have a big stock of this Growatt SPF 5000 ES .
The cheapest was 715usd DDP to germany. some were at 850 usd DDP to Germany but have no expreience yet
SO if someone can give any advice thanks in advance
