Modular 5.12-76.8kWh Off-Grid Energy Storage System with Dual MPPT & UPS Backup3

Product Description

The ACE LV ESS (All-in-One System) is a revolutionary off-grid energy storage solution designed to deliver uninterrupted power in areas with unstable grids. Built with stackable LiFePO4 battery modules, this system offers unparalleled flexibility with capacity options ranging from 5.12kWh to 76.8kWh. Its dual-channel MPPT technology maximizes solar harvest efficiency (up to 93.5%) even on multi-orientation roofs, while the ≤20ms UPS switch-over ensures zero blackout for critical home appliances.

Featuring integrated wheels for portability and a sleek stackable design, the ACE LV ESS adapts to diverse scenarios—from residential backup power to RV, marine, and remote industrial use. The high-performance BMS supports seamless integration with 15+ inverter brands (including Deye, Sungrow, and Victron Energy) and provides multi-layer protection. With a 6,000-cycle lifespan at 80% DoD and wide operating temperatures (-10°C to 50°C), it’s engineered for decade-long reliability.
