It helps estimate how much stored energy is needed to power household or industrial equipment during outages. The basic formula is:

Battery Capacity (Ah) = Load Power (W) × Backup Hours / (Battery Voltage × Efficiency)

Examples:

• A 5kWh rack battery cabinet can support a small home inverter system for hours.

• A 372kWh liquid-cooled ESS provides long backup for industrial inverters.

How to Calculate Inverter Battery Capacity?

• Identify Load Power (W): Total wattage of connected appliances.

• Decide Backup Hours: Desired inverter runtime.

• Select Battery Voltage: 48V for small systems, higher for ESS.

• Consider Efficiency: Inverter & battery losses reduce usable energy.

Example: 1000W load, 4 hours, 48V, 90% efficiency →
Capacity = 1000 × 4 ÷ (48 × 0.9) ≈ 93Ah (~4.5kWh).

Factors Affecting Inverter Battery Capacity

• Load Variation: Larger or unstable loads require more capacity.

• Battery Chemistry: LFP batteries provide longer lifespans.

• Cooling Method: 144kWh air-cooled ESS balances cost & performance; 215kWh or 3.35MWh liquid-cooled ESS handles heavy loads efficiently.

• Depth of Discharge (DoD): Higher DoD allows more usable energy.

Applications of Inverter Battery Capacity Calculation

• Home Backup: 10kWh wall-mounted ESS supports home inverters.

• Commercial Projects: 100–241kWh air-cooled ESS secures critical loads.

• Industrial Use: 372kWh liquid-cooled ESS powers large inverter equipment.

• Utility-Scale: 3.35MWh liquid-cooled ESS container integrates with inverter stations.

Price of Inverter Battery Capacity Solutions

Cost depends on:

• Capacity size (kWh/MWh)

• Cooling method (air vs liquid)

• Cycle life & performance

• Installation & logistics

Dagong ESS offers EXW, FOB, or CIF quotations tailored to projects.

How to Choose the Right Inverter Battery Capacity?

• Homes: 5–10kWh ESS is sufficient.

• Businesses: 100–241kWh ESS balances peak loads and runtime.

• Large Projects: 3.35MWh liquid-cooled ESS container fits renewable & industrial needs.

How Long Does Inverter Battery Capacity Last?

High-quality lithium systems (like 215kWh or 372kWh ESS) provide 8000+ cycles, keeping over 80% capacity, ensuring 15+ years of inverter reliability.
