Use cases:

• A company have PCU, GTI, Zelio, Regalia, iCruze Inverters,
• All Inverters have a Power rating which is determined by ( Current * Operating Voltage )
• Only PCU, GTI, and Regalia are solar Inverters other are not (solar inverters get charged by solar panels and solar energy,
• Solar Inverters have Solar Panels also
• Solar Inverters further have two option one Battery version that whatever energy is produced will be stored in a battery other will not store any energy, so PCU comes with a battery but GTI has no battery,
• Solar Inverter also has GRID On, a system where you can sell your extra energy back, GTI is GRID On whereas this feature is not available in PCU,
• Non-Solar Inverters are Simple Home Inverters That have a Battery
• Design this assessment with OOPS.
