Traditional Power System

Inside Building

…………………………………………………………………………….……………………..

Problems in Traditional Power System

• Safety: high voltage; need electrician for installation and maintenance

• Efficiency: require inefficient AC/DC conversion for DC load

• Distribution: still use mechanical switches with long response time; high short circuit current; no remote control

• Integration: need DC/AC conversion to ingrate PV or battery into the system.
