Design of ESS

I am looking for a skilled designer to create an Energy Storage System (ESS) for residential use. Only electrical consumption and not cogenerative (heat and electricity) fuel cell and electrolyser. The ideal candidate will have experience in designing ESS with battery storage technology and a capacity of a residential building with around 20 single units. The goal is minimizing the costs and maximizing the self-consumption (at least 60%). The project includes the following requirements: - Design an ESS with battery storage technology for residential use - 20 residential units - Fixed size of PV generation, it means the power of the PV panel is equal to the maximum power for the residential unit, this is 20x3 kW or 60 kW; - Include all necessary components such as inverters, charge controllers, and batteries. The control could be a basic one. - The initial value of the storage is at 50% of state of charge (both battery and hydrogen); - Provide a detailed design plan and schematics for the ESS - Ensure the ESS is safe, reliable, and efficient - The software can be disccussed. - The data for PV generation and Load profile are provide by me. -A detail explanation is needed. Ideal Skills and Experience: - Experience in designing ESS with battery storage technology - Knowledge of energy storage systems, renewable energy, and power electronics - Proficiency in electrical design tools - Excellent problem-solving skills and attention to detail
