Specification

FEATURES
Massive 20.48KWh Capacity: A LiFePO4 Lithium Battery That Powers Entire Operations
At the heart of this power box lies a 51.2V 400Ah LiFePO4 Lithium Battery delivering 20.48KWh of energy—enough to run multiple high-demand devices simultaneously. From construction tools (e.g., angle grinders, air compressors) to event equipment (sound systems, lighting rigs) or emergency medical devices, this LiFePO4 Lithium Battery system eliminates the need for multiple smaller batteries or noisy generators.
6000+ Cycles & Wide Temp Tolerance: A Battery Energy Storage System Built for Longevity
Durability is non-negotiable for a battery energy storage system, and this unit delivers with >6000 charge-discharge cycles (at 25℃, 0.5C/0.5C, 100% DOD) and remaining capacity >70%—that’s 8–10 years of regular use (far longer than lead-acid battery energy storage system models, which last 500–1000 cycles). It also performs in extreme temperatures: discharging from -20℃ to 60℃ and charging from 0℃ to 60℃—so whether it’s a freezing winter rescue or a scorching summer festival, this battery energy storage system maintains peak performance without capacity fade.

Triple Charging Options: A Battery Energy Storage System That Adapts to Any Environment
Flexibility sets this battery energy storage system apart: it supports three recharging methods to fit any scenario, a feature rarely matched by basic battery energy storage system alternatives:
AC 230V Charging: Reaches 80% capacity in 3.5 hours and 100% in 4.5 hours—ideal for grid-connected areas like job sites or emergency shelters.
Solar PV Charging: Compatible with 6kW solar panels (MPPT voltage range 65–245VDC), letting the battery energy storage system harvest energy in off-grid locations (e.g., remote construction sites, camping grounds).
Rema External Rapid Charging: Hits 80% in just 2.5 hours and 100% in 3 hours 10 minutes—perfect for time-sensitive situations like emergency response or event turnarounds.
This multi-charging capability makes the battery energy storage system a reliable choice whether you’re near a power outlet, under the sun, or in a hurry.

8KVA Inverter with Surge Protection: A Battery Energy Storage System for Heavy Loads
Equipped with a 48V/8000VA inverter, this battery energy storage system handles high-power devices that stall smaller units: it supports 8KVA continuous output and 15KVA peak surge (for 5 seconds)—enough to start a 5000W generator or power a 6000W industrial heater. The inverter also features strict voltage regulation (230VAC ±5%) to protect sensitive electronics like laptops, medical monitors, or LED lighting from voltage spikes. For tradespeople or emergency teams, this battery energy storage system means no more choosing between powering tools or delicate equipment—it does both safely.
Comprehensive Safety & Smart Monitoring: A Battery Energy Storage System You Can Trust
Safety is embedded in every part of this battery energy storage system: it includes RCBO protection (for overloads and short circuits), a battery isolator (to prevent accidental discharge), and a high-temperature cut-off. The on-board control panel adds transparency, letting you monitor State of Charge (SOC), voltage, and current in real time—so you always know how much power the battery energy storage system has left. Unlike unmonitored battery energy storage system models, this unit eliminates guesswork, helping you plan recharging and avoid unexpected downtime.



The ECOLITE 8KW/20KWh Portable Power Box’s versatility, power, and durability make it the perfect LiFePO4 Lithium Battery solution for a range of commercial and industrial use cases:
Emergency Response & Disaster Relief: Powers medical equipment (e.g., defibrillators, oxygen concentrators), communication radios, and emergency lights at disaster sites. The battery energy storage system’s wide temperature tolerance and rapid charging let it perform in hurricanes, wildfires, or winter storms.
Outdoor Events & Festivals: Supplies power for food trucks (small fridges, grills), stage lighting, and vendor booths. Solar compatibility makes the battery energy storage system eco-friendly, while multiple USB/AC ports handle both professional and personal devices.
Industrial Temporary Power: Supports tools (e.g., electric welders, grinders) and monitoring sensors at construction sites or maintenance projects. The 8KVA inverter handles heavy loads, and the battery energy storage system’s long cycle life reduces replacement costs for ongoing projects.
