Sunpal 50KW 55KW 60KW High Voltage Three Phase Hybrid Inverter

In order to ascertain the most suitable battery size for your business, please consider the following factors:

Required Backup Duration

Assess how many days your business needs to operate without grid power.

For instance:

1-day autonomy: 50 kWh × 1 = 50 kWh
2-day autonomy: 50 kWh × 2 = 100 kWh
3-day autonomy: 50 kWh × 3 = 150 kWh

Entladungstiefe (DoD)

To prolong battery life, avoid discharging below a certain percentage.

For example, with a 90% DoD:

1-day capacity: 50 kWh ÷ 0.9 ≈ 56 kWh
2-day capacity: 100 kWh ÷ 0.9 ≈ 111 kWh
3-day capacity: 150 kWh ÷ 0.9 ≈ 167 kWh

System Efficiency

Account for energy losses during conversion and storage.

Assuming 85% efficiency:

1-day requirement: 56 kWh ÷ 0.85 ≈ 66 kWh
2-day requirement: 111 kWh ÷ 0.85 ≈ 130 kWh
3-day requirement: 167 kWh ÷ 0.85 ≈ 196 kWh

Recommended Battery Capacity

Based on the above factors, a battery system with a capacity between 66 kWh and 196 kWh is suitable, depending on your backup duration and system specifications.

Considerations for Businesses

Battery Type: Lithium-ion batteries are preferred for their efficiency and longevity.

Integration with Solar: If integrating with solar panels, ensure the system efficiently charges the batteries.

Budget: Costs vary; for example, a 136 kWh system may cost approximately $54,400.

Regulatory Compliance: Ensure the system complies with local regulations and standards.

Scalability: Consider future energy needs and choose a system that can be easily scaled.
