EA POWER 24V Solar Inverter for Home & Battery Storage


The EA POWER 24V Solar Inverter is a versatile, high-efficiency solution designed to convert solar-generated DC power into stable AC electricity for residential use or battery storage systems. Compatible with 24V solar panels and battery banks, it integrates MPPT technology to maximize solar energy harvesting, achieving ≥97% conversion efficiency even under partial shading or fluctuating sunlight.


Key Features:

Dual Output Modes: Seamlessly switches between powering household appliances (e.g., refrigerators, air conditioners) and charging lithium/lead-acid batteries. Supports 3,000W continuous AC output (6,000W surge) for high-demand devices.

Smart Energy Management: Built-in WiFi/Bluetooth connectivity enables real-time monitoring via mobile apps, allowing users to track energy production, consumption, and battery status. Configurable charging modes (Solar Only, Hybrid) optimize energy use during peak/off-grid hours.

Robust Safety & Durability: Features pure sine wave output (THD ≤3%) to protect sensitive electronics, with multi-layer protections against overvoltage, overload, short circuits, and overheating (-20°C–60°C operation). The IP65-rated aluminum casing ensures resistance to dust, moisture, and corrosion.


Applications:

Residential Solar Systems: Powers homes during daylight and stores excess energy in 24V batteries for nighttime use.

Off-Grid Backup: Ideal for remote cabins or emergency power during grid outages, supporting up to 20kWh daily energy storage.

Hybrid Configurations: Integrates with grid-tied systems to reduce electricity bills through net metering.

Certified to CE, ISO9001, and UN38.3 standards, this inverter combines reliability with a 5-year warranty, making it a sustainable choice for eco-conscious households.
