Inyección Red Multiplus 500W

Greetings to all members of the community. I have two questions regarding the Multiplus 500W product.

With this Multiplus device, is it possible to inject energy into the grid as is done with higher power Multiplus devices?
The second question is whether, if a higher power load is connected, it can draw energy from the grid to supply that load as higher power Multiplus devices do?

Tks
