Source: ankersolix.com (verified 2026-08-01) · corroborated by solarreviews.com. Anker's official X1 page confirms the system is modular from 5 kWh (1 battery module, 3 kW continuous / 4.5 kW peak for 10s) up to 30 kWh per power module and 180 kWh across 6 paralleled systems, with LiFePO4 chemistry, up to 90.2% round-trip efficiency, and a 10-year warranty. Because the only weight and price data points found (SolarReviews' independent review) both specifically describe a 15 kWh configuration (389 lb, ~$9,750-$11,000), that mid-tier size is reported here as the 'base config' for internal consistency, with continuous/peak power (6 kW / 12 kW for 10s) taken as Anker's 'standard configuration' figures rather than the bare single-module minimum (noted for comparison: a single 5 kWh module is capped at 3 kW continuous / 4.5 kW peak). No confirmed backup-transfer-time figure was found.
