Pick Your Priority Outputs, Extend What Matters Most

Smart Remote Switching | Reduce waste to increase runtime for essentials

DELTA 3 Max Plus introduces Smart Output Priority Tech. This convenient new feature lets you choose which circuits stay powered via the app. Prioritize what matters—like your fridge, Wi-Fi, or medical devices—and extend runtime when it counts most, even when you're away.

Smart Power Reserve | Set your desired battery threshold (%) to automatically shed non-essential loads during outages

With app-based presets, DELTA 3 Max Plus automatically follows your priority settings during outages—shutting off lights while keeping your fridge running. Wake up to fresh food and plenty of power left—just like nothing happened.

Automotive-grade Full-Tab LFP Cells: Next-Level Battery Reliability

 

DELTA 3 Max Plus is equipped with automotive-grade full-tab LFP cells. The full-tab design reduces resistance, enhances efficiency and safety, and provides higher capacity with less heat, resulting in a longer battery lifespan.

Unrivaled Balance for Unmatched Battery Longevity

 

With 27% fewer cells per kWh, [7] our 16-cell design runs cooler, lasts longer, and delivers greater stability. Each cell is rigorously tested for capacity, voltage, and internal resistance—resulting in a highly uniform pack that protects against overcharging, imbalance, and premature wear.

Built to Last

 

From battery chemistry to structural design, DELTA 3 Max Plus is engineered for extreme durability, environmental resilience, and whisper-quiet performance—delivering power you can count on for over 10 years. [2]
