The PowerPro WallMount All Weather 280Ah batteries are ideal for low-voltage residential outdoor energy storage system (ESS) applications. The batteries use lithium iron phosphate cells with the highest safety performance and an intelligent Battery Management System (BMS) that can monitor and record the voltage of each cell along with the current, voltage, and temperature of the module in real-time. The BMS also contains a passive balance function and an advanced battery control method, both of which improve the performance and longevity of the battery pack.
Key Features & Benefits
Built-In 200A BMS: Intelligent Battery Management System monitors cell voltage, current, temperature, and module health in real-time with passive balancing.
Integrated 600A Busbars: Internal busbars with multiple terminals (4 positive & 4 negative) eliminate the need for external busbars when paralleling batteries and/or multiple inverters.
82.6MWh Lifetime Production: High lifetime energy throughput for long-term value.
10 Year Warranty: Backed by EG4's 10-year limited warranty.
>8000 Cycles @ 80% DOD: Exceptional cycle life at 0.5C discharge rate.
On-Board LCD Touch Screen: Easy to see BMS monitoring with selectable closed-loop communications for EG4, Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye inverters.
Dual On-Board Fire Arrestors: Offer fail-safe protection against thermal runaway for enhanced safety.
Weather-Tight Quick Connects: Included battery cables with outdoor rated connectors allowing for fast, safe, and reliable battery connections.
Integrated Self-Heating Feature: Heats the battery when ambient temperature is low (≤32°F / 0°C) - a key feature for outdoor lithium battery cell operations.
Innovative Emergency Stop Function: Optional ESS disconnect can shut down all batteries and inverters (if equipped with rapid shutdown capability) with the press of a button.
Perfect Partner to EG4 18kPV: Optional conduit box mates directly to the inverter allowing a sleek and efficient installation.
IP65 All-Weather Rating: Weather-tight enclosure suitable for outdoor installation.
