Solar inverter ECO SOLAR BOOST EVO MPPT-4000 GRID 4KW

Hybrid Solar Inverter ECO Solar Boost EVO MPPT-4000 Grid for water heating

Are you looking for an efficient, reliable and maximally autonomous solar water heating or heating solution that won't leave you stranded at night or in inclement weather? The ECO Solar Boost EVO Grid inverters represent a new generation of renowned and appreciated devices that allow the direct use of photovoltaic panels to power heating equipment.

This range has been designed based on years of engineering experience and valuable customer feedback. In addition, the use of Artificial Intelligence (AI) in the design process makes it even more reliable and optimised in its architecture.

Key benefits:

- Hybrid 24/7 operation (Automatic grid/solar switching). In the event of a power failure from the photovoltaic panels (e.g. at night or during heavy rain when the voltage drops below 40 V), the heater power is automatically switched from the solar circuit to the grid circuit. As soon as the sun comes out again and the voltage on the panels rises above 80 V, the inverter switches back to solar priority. The heating devices thus operate regardless of the time of day.
- High performance and improved algorithm.
- Maximum gains with MPPT: The integrated MPPT algorithm intelligently regulates the amount of energy transferred to the heater, maximizing the energy collected from the PV panels and automatically adjusting to the heater's output.
- The inverter clearly informs the user of the current operating mode via LEDs (PV/AC). In addition, it includes a unique 5 LED power indicator that indicates the instantaneous power supplied to the heater with 10% accuracy (in 400 W increments).

Example: if the first LED is on steady and the second LED is flashing, the current power delivered is between 801 W and 1200 W. When all 5 LEDs are on, the maximum power draw is between 3601 W and 4000 W.

Technical specifications:

Supported panel power: The system requires standard 400-700 W panels connected in series or series-parallel. The total voltage must be in the range of 120 V to 300 V ($V_{oc}$ at 25 °C), the absolute operating range of the inverter is 120-350 V DC.Maximum panel power: The inverter has an internal power limit of 4 kW, but the total installed power of the connected panels must not exceed 5 kW.Recommended panel power: For normal boilers (50-200 l) in spring-autumn operation, the optimum panel power is 1000-2000 W. For year-round operation, it is recommended to increase the power due to winter cloud cover and low sun angle. The connected heating element must have a power output of 200 W to 4000 W / 230 V.
