Customer Reviews
A qualidade do produto é bem premium, funciona muito bem e basicamente estou usando como sistema off-grid em uma casa com dois painéis de 500W cada.
I cannot believe how life became so easy and simple with my ecoflow delta pro 3 system. Very easy to install and operate! I cannot wait for delta pro ultra to be released in europe so i can buy it as well.
