Let's us know how do you think about it.

There was an interesting poll on this Tuesday, in various groups. The topic is for solar installers, which coupling (AC/DC) approach prevails in home energy storage system projects? The results are shown in the pictures.

Here I make a data summary. A total of 259 votes were received, among which 104 were AC coupling votes, accounting for 40%. Dc coupling 155 votes, accounting for 60%.Conclusion: 1)The voting results show that DC coupling system accounts for 60%  
2)This data show that the current home energy storage market is mainly from the new installed market? Because the DC coupling system is more suitable for the new installation of the system, while the AC coupling has more advantages for the transformation of the solar system. 
3)It mean that the hybrid inverter has become the mainstream.Energy storage systems matching hybrid inverters will be more popular in the market.The above conclusions do not consider the differences of sample countries and regions, just for reference.

Were these results what you expected? And do you think they'll change in the coming 1-3 years?
