Lithium Battery Selector

The Enexer Lithium Battery Sizing Calculator helps you determine the right lithium battery configuration for your energy storage needs. By using your daily energy consumption (Wh/day), system voltage, depth of discharge, and desired backup duration, the tool calculates the required battery capacity and recommends the most suitable Enexer lithium battery model and quantity for your system.

This tool works as both a sizing calculator and a selector. It first calculates the battery capacity your system requires based on your inputs, then selects the optimal Enexer lithium battery model and quantity—prioritizing the fewest batteries and lowest total cost—making it easy to choose the right solution.

“Days of autonomy” refers to how many days your battery system can supply power without any charging source, such as solar or grid power. For example, 1 day of autonomy means the batteries can support your daily energy usage for one full day on their own. Increasing this value increases the required battery capacity.

The Enexer Lithium Battery Selector supports 12V, 24V, and 48V nominal system voltages. This allows it to work for a wide range of applications, including RVs, solar energy storage systems, and off-grid or backup power setups.

The calculator provides reliable estimates based on standard assumptions and your inputs. However, actual battery requirements may vary due to factors such as inverter efficiency, surge loads, temperature, battery aging, wiring losses, and overall system design. For mission-critical or complex systems, we recommend confirming the results with a qualified professional.

Yes. Once the calculator generates a recommendation, you can add the suggested Enexer batteries directly to your cart with one click, making it easy to move from system sizing to purchase without additional steps.
