Introduction

As energy storage systems scale up, LiFePO₄ batteries are often deployed in parallel or modular configurations. This introduces additional requirements for inverter design and control.

Parallel Inverter Operation

Inverters used with parallel LiFePO₄ battery systems must support:

• Load sharing between inverters
• Synchronized voltage and frequency
• Stable communication between units

Battery Parallel Management

When multiple LiFePO₄ battery packs are connected:

• BMS communication must remain consistent
• Inverter must recognize total system capacity
• Charging current distribution must be balanced

Scalability and Expansion

A scalable inverter allows system expansion without redesigning the entire energy storage architecture, which is critical for commercial and industrial (C&I) applications.
