Eastman MX-ECO hybrid solar inverter series-EM-3224 MX-ECO

Eastman EM-3224 MX-ECO – 3.2kVA 3200W 24V Hybrid Solar Inverter

The Eastman EM-3224 MX-ECO is a 3.2kVA / 3200W off-grid hybrid solar inverter designed to provide dependable power for homes, offices, shops, and other applications requiring efficient solar energy management. It combines an inverter, solar charger, and battery charger in one compact system, helping simplify off-grid and backup-power installations.

Operating with a 24VDC battery bank, the inverter delivers 230VAC pure sine wave output with a rated capacity of 3200VA/3200W and a 6400VA surge capacity. Its pure sine wave output makes it suitable for a broad range of household and office equipment, including electronics and motor-driven appliances.

The integrated MPPT solar charger supports up to 3500W of PV array power, with a 60–450VDC MPPT operating range and up to 100A solar charging current. This allows the system to efficiently convert available solar energy into usable power while charging the connected battery bank.

The inverter also provides configurable AC/solar charging priority, smart battery charging, cold-start capability, automatic restart after AC recovery, and protection against overload, overheating, short circuits, and low battery voltage. Optional Wi-Fi connectivity is available for compatible monitoring configurations.
