MILLY MALLY ECO SOLAR BOOST EVO MPPT-4000 PRO GRID 4kW Solar Inverter

For direct solar-powered heating with grid backup, the ECO SOLAR BOOST EVO MPPT-4000 PRO GRID stands apart from conventional inverters by prioritizing PV output to your heating loads while seamlessly switching to grid power when solar energy is insufficient. This grid-assisted solar heater inverter eliminates the need for batteries, reducing system complexity and cost while maximizing self-consumption of solar energy.

Highlights

• 4000W rated power for demanding heating applications
• Advanced MPPT technology with >99% tracking efficiency
• Wide MPPT voltage range: 120V - 450V DC
• Priority output for PV power ensures maximum solar utilization
• Automatic grid backup for uninterrupted heating
• Clear LCD display for real-time monitoring
• Robust protection: overload, short circuit, over temperature, reverse polarity
• Fan-forced cooling for reliable operation in temperatures from -25°C to +55°C

In daily use

The ECO SOLAR BOOST EVO MPPT-4000 PRO GRID is engineered for direct connection to resistive heating loads such as water heaters, space heaters, or heat pumps. Its intelligent control logic continuously monitors PV production and load demand, directing every available watt of solar power to the heating element. When solar output drops below the load requirement, the inverter automatically supplements from the grid, ensuring consistent heating performance without manual intervention. The RS485 communication interface (with optional WiFi/GPRS module) allows remote monitoring and configuration, making it easy to track energy production and adjust settings from anywhere.
