High-Capacity 14.34kWh Energy Storage

The 14.34kWh capacity makes the Volta Stage 4 suitable for applications where a larger battery reserve is required. It can store excess electricity generated by photovoltaic solar panels and make that energy available when solar production is reduced or unavailable.

This makes the battery ideal for:

• Solar self-consumption
• Evening energy usage
• Load shifting
• Backup power
• Load shedding protection
• Hybrid solar systems
• Off-grid installations
• Residential and commercial energy storage

High-Performance 280Ah Battery

With a 280Ah nominal capacity and 200A maximum discharge current, the Stage 4 is designed for higher-energy applications. Its 1C/1C continuous charge and discharge capability supports demanding energy storage applications when the battery is installed and configured according to the manufacturer’s requirements.

Long Cycle Life

The Volta Stage 4 is rated for at least 6,000 cycles at 80% DoD, based on the manufacturer’s stated test conditions. This makes it suitable for applications involving frequent daily charging and discharging, such as solar energy storage and load shifting.

Wi-Fi Remote Monitoring

The battery includes Wi-Fi remote monitoring and cloud management functionality, allowing users to monitor battery operation remotely through supported monitoring systems. This provides greater visibility of the energy storage system and can assist with system management and maintenance.

Flexible Installation

The Volta Stage 4 supports two installation methods:

• Wall mounted
• Floor standing using the removable floor stand

This provides installers with greater flexibility when designing the battery installation around available space and system requirements.

Expandable Battery Storage

The Stage 4 supports up to 16 battery modules in parallel, allowing the total energy storage capacity to be increased for larger residential, commercial, and off-grid installations.

When 16 Stage 4 batteries are configured together, the nominal combined storage capacity is approximately 229.44kWh, subject to system configuration and manufacturer requirements.

Inverter Compatibility

The Volta New Generation battery range is shown as compatible with a range of inverter brands, including:

• Growatt
• LuxPowerTek
• Deye
• Voltronic Power
• SMA
• GoodWe
• SRNE
• Sofar
• Victron Energy
