Choosing a home energy storage system starts with understanding battery capacity, the loads that need support and the planned solar or backup configuration. LinkPower's all-in-one LiFePO4 range includes 5kWh, 10kWh and 16kWh options for different residential energy storage requirements.

What Battery Capacity Means

Battery capacity describes how much energy a system can store. It does not by itself determine exact backup time. Actual runtime depends on connected loads, operating conditions, inverter settings and system configuration.

5kWh System

The 5kWh model provides 5.12kWh of stored energy in a 51.2V / 100Ah LiFePO4 configuration. It is the smallest and lightest of the three compared systems.

10kWh System

The 10kWh model increases stored energy to 10.5kWh with a 51.2V / 206Ah battery configuration while retaining a 6200W inverter rating.

16kWh System

The 16kWh model provides 16.08kWh of stored energy with a 51.2V / 314Ah battery configuration. It offers the highest stored energy of the three compared systems.

Factors to Check Before Selecting a System

  1. Identify the appliances and circuits that require backup.
  1. Calculate expected energy consumption and required backup duration.
  1. Confirm the solar array and PV input configuration.
  1. Check available installation space and system weight.
  1. Confirm local electrical, installation and compliance requirements.

Request Project Matching Support

The correct capacity depends on the real load profile and installation conditions. Contact LinkPower with the target loads, required backup time and solar configuration for project-specific system matching.
