• Critical business circuits

Commercial Solar Generator & Energy Storage System

The LionESS Vault can also function as the heart of a commercial solar generator system. Connect compatible solar arrays to capture solar energy during the day, store that energy in the Vault's LiFePO4 batteries and use it when needed.

The system is designed for both on-grid and off-grid applications and is also generator-ready, giving businesses multiple ways to maintain reliable power.

Up to 171.6 kWh of Battery Storage

The LionESS Vault uses modular 14.3 kWh Sanctuary 3 Lithium Iron Phosphate batteries. Systems can be configured from 57.2 kWh up to 171.6 kWh of nominal battery storage, allowing the Vault to support applications ranging from large residential and light-commercial backup to substantial commercial installations.

Up to 72 kW Commercial Backup Power

Commercial LionESS Vault configurations can deliver up to 72 kW of AC output with up to 108 kW of solar input, providing the power needed for demanding business applications.

Popular LionESS Vault Configurations

*Output and solar-input specifications depend on the selected commercial configuration. Contact All Pro Generators for system design and confirmation.

Lithium Iron Phosphate Battery Technology

Each Sanctuary 3 battery provides 14.3 kWh of energy storage using Lithium Iron Phosphate (LiFePO4) chemistry. LFP technology is well suited to stationary energy storage because of its safety characteristics, long service life and stable chemistry.

Solar & Generator Ready

The LionESS Vault gives businesses multiple energy options. The system can integrate utility power, battery storage, solar generation and compatible generator backup to create a flexible commercial energy solution.

This makes the Vault an excellent option for businesses looking for:

• Commercial battery backup
• Commercial solar generator systems
• Commercial solar battery storage
• Business backup power
• Peak shaving
• Demand management
• On-grid energy storage
• Off-grid commercial power
• Solar plus storage
• Generator and battery hybrid backup

Peak Shaving & Energy Management

The LionESS Vault isn't limited to emergency backup. Stored energy can also help businesses manage when and how they consume utility power. Depending on the installation and utility program, this can help reduce peak demand and shift energy consumption to more favorable times.

Outdoor NEMA 3R Enclosure

The Vault is housed in a secure Type 3R / NEMA 3R enclosure designed for outdoor installations. Major system components arrive pre-assembled with integrated internal wiring and breakers, helping simplify installation compared with assembling a large commercial battery system from individual components.

Remote Monitoring & Control

Monitor system performance and energy flow remotely. Lion Energy's monitoring capabilities provide visibility into battery status, solar production and energy usage, while allowing system settings and essential loads to be managed.

For businesses with multiple locations, centralized monitoring can make the LionESS Vault particularly attractive for commercial deployments.
