Energy Storage, Engineered for Scale

Dependable battery energy storage systems (BESS) for utility, industrial, and commercial-grade power supply.

Utility-Scale Power, Anywhere You Need It

When you need to stabilize the grid, support renewables, or deliver reliable energy where infrastructure falls short—you need GridBox. We build containerized battery systems for utilities, developers, and companies who need flexible, fast-deploying energy storage at scale.

Residential Solutions

With the HomeGrid Cube we’ve paired the power of our Stack’d Series battery and Sol-Ark inverters into a single weatherproof and temperature controlled enclosure. Best suited for large residential and small commercial projects, the HG Cube can supply the needs of any site.

Powerful Applications

Peak Shaving + Valey Filling

Charges during off-peak hours when electricity prices are low and discharges during peak hours to reduce electricity costs.

Demand Response

Adjusts charging and dischcarging based on grid demand, either by discharging power or reducing charging when requested by the grid operator.

Renewable Energy Integration

Stores excess energy from renewable sources like solar and wind and releases it when needed, smoothing out intermittent generation.

Load Shifting

Stores excess electricity during low-demand periods and releases it during high-demand periods to balance grid load.

Energy Arbitrage

Charges when electricity prices are low and discharges when prices are high to generate revenue from price differences.

Frequency Regulation

Charges or discharges in response to grid supply and demand imbalances; a process that ensures the electrical grid maintains a stable frequency.

FAQs

Can more than one GridBox unit be utilized to reach a higher kW
output and/or kWh capacity for industrial energy storage?
Yes, multiple GridBox units can be paralleled together to reach the desired kW output and/or kWh capacity. When deploying more than one GridBox unit on the same system, a master controller is required. GridBox systems are compatible with most third party master controllers.  
What GridBox products currently are PV and DC-coupling
capable and how much kWdc can be connected?
All 10GB-0100 GridBox products have inherent PV DC-coupling capabilities. PV solar kWdc capacity is 200kWdc with a max voltage of 900Vdc. Other configurations are possible based on specific project needs. 
What GridBox products currently are PV AC-coupling capable
and how much PV kWac can be connected?
All GridBox products are PV AC-coupling capable. However, when operating GridBox with AC-coupled PV in Grid Island (standby mode) operation a microgrid controller is required. The controller will choreograph when to discharge and charge GridBox, when to curtail PV solar production when GridBox is fully charged, and when facility load does not exceed OV solar kW output. Also please note, an appropriately sized electric panel or switchboard, external to the GridBox, will be required to provide breaker or fused switches to allow all sources to parallel with each other.
Can Lithion Battery and GridBox offer a microgrid controller and remote monitoring to integrate AC-coupled PV solar and battery energy storage systems (BESS)? How does it work? 
Yes, Lithion Battery offers the GridBox EAM. The EAM includes a gateway device and data aggregator with onsite data storage. The gateway device acts as a firewall interface between the Lithion Battery 24/7 command center that monitors BESS installations, and the data aggregator. The data concentrator polls data from each GridBox at a high rate to capture operational change of state and analog values. That data is then analyzed at the site to consolidate key trouble alarms, failure alarms, temperature values, operational status, and more to reduce the amount of data streamed through the gateway device to the command center. Data sets will be updated every 15 minutes in this command center. Any trouble or failure alarms will trigger an event report containing high resolution data capturing of pre-events leading up to the triggered event. The algorithm in the data concentrator will issue pre-fault maintenance alarms to notify customers of predicted failures, allowing them time to have the components serviced before they fail and cause further issues. Predicted failure alarms also allow customers to resolve issues before they occur to better guarantee BESS uptime. 
Do you offer customized warranty options?
Yes, our warranties are customizable with full augmentation options available.
