Do i need a extra DC-breaker between the EnergyHub and DC-distribution?

 For smaller facilities such as homes and villas, this is not necessary because the DC-breaker in the DC distribution is often relatively easily accessible and can be used to break and separate the facility. For facilties where the DC distribution is located far from the EnergyHub, there may be a point in installing an extra DC-breaker at the EnergyHub to get an easier opportunity to separate different parts of the DC-grid for maintenance.
