Ecolion 4kWh Solar Lithium Battery
Ecolion is a brand known for LiFePO₄ deep cycle batteries made for solar, inverter, and off-grid backup. While the exact “4kWh” model specs vary by voltage, here’s the full description based on Ecolion’s LiFePO₄ line and typical 4kWh units
Features & Benefits
Long Lifespan: 4000+ cycles vs 300-500 cycles for lead-acid. That’s 10+ years daily use
Safety: LiFePO₄ has excellent thermal + chemical stability. No fire/explosion risk like other lithium
Deep Discharge: Can use 80-100% DoD without damage. Lead-acid only 50%
Fast Charging: Higher charge current + efficiency vs lead-acid
Maintenance-Free: No water topping, no acid spill. Just install and use
Expandable: Most Ecolion LiFePO₄ batteries can be paralleled 4-16 units for more capacity
Smart Monitoring: BMS with RS485/CAN lets you connect to inverters like Growatt, Victron, Sol-Ark for closed-loop comms
Applications
Designed for:
Solar Energy Storage: Store solar power for night use
Inverter Backup: Replace UPS/lead-acid batteries for home/office
Off-Grid Systems: Cabins, farms, shops with no grid
Telecom Towers: 24/7 reliable power
CCTV + Security: Stable backup for critical loads
What 4kWh Can Run – Realistic Load
With 3.2kWh usable @ 80% DoD:
Light load: 4 bulbs 15W + TV 100W + Fan 50W + Laptop 60W = 225W → ∼14 hours
Fridge + Freezer: 150W running 1/3 time = 1.2kWh/day + other loads
0.5HP AC: 500W → ∼6 hours
Water pump 1HP: 750W → ∼4 hours
Installation Notes
Match voltage: 12V battery must go with 12V inverter. 48V battery = 48V inverter
Wiring: Use thick cables. 4kWh @12V can pull 300A+
Ventilation: Keep at 15°C-35°C for optimal life
Parallel: Can add more Ecolion batteries later if load increases
Bottom line: Ecolion 4kWh is a plug-and-play LiFePO₄ battery for anyone wanting low maintenance, long life
