Each DELTA Pro Ultra Battery Pack adds 6144Wh of LFP storage to the DELTA Pro Ultra system. Connect one for 12,288Wh total, two for 18,432Wh, or three for the maximum 24,576Wh — providing 3–5 days of whole-home backup for an average household. The BMS manages charging and balancing across all connected packs automatically.
The DELTA Pro Ultra Battery Pack uses the same LFP cell chemistry as the base DELTA Pro Ultra for matched longevity and consistent performance across the full charge range. Integration with the Smart Home Panel 2 covers the entire expanded system for automatic whole-home circuit failover.
