• Product description

  • Solar inverter ECO Solar Boost EVO MPPT-4000 PRO represents a modern and highly reliable solution for direct water heating and space heating using solar energy, entirely without the need for connection to the distribution grid (off-grid) or the purchase of expensive batteries.
  • Thanks to an enhanced architecture designed with the support of artificial intelligence (AI) and an innovative MPPT algorithm, the inverter intelligently maximizes energy harvest from photovoltaic (PV) panels even under reduced light conditions, such as sunrise or sunset.
  • The device offers a maximum power of up to 4000 W and a current of 16 A, making it ideal for powering purely resistive appliances – from water heaters and thermal storage tanks to electric radiators and convectors, as well as heating mats or infrared heaters.
  • A major advantage of the PRO version is the integrated LCD display, which provides the user with continuous and detailed real-time system information.
  • You can conveniently monitor the current voltage from the photovoltaic panels (V), the current generated by the panels (A), the instantaneous output power to the load (W), the energy produced today (kWh), the energy produced yesterday (kWh) and the total energy produced since system start-up (kWh) directly on the display.
  • The model features a dual output in the form of two standard type E sockets (with earth pin), operating on a priority-switching principle.
  • The system primarily heats devices connected to Output 1.
  • Once that device’s thermostat reaches the set temperature and power draw stops, the inverter automatically redirects power to Output 2.
  • Completely safe operation is ensured by integrated electronic protection against overload, short circuit, overvoltage and overheating (at 80 °C).
  • If an anomaly is detected, it shuts down immediately and clearly signals the fault directly on the LCD display.
  • Important wiring note: While the priority Output 1 is universal and may be used with any heating appliance (including those with electronic controllers), the dependent Output 2 is intended exclusively for heaters with a bimetal thermostat. Devices with electronic control must not be operated on the second output.
  • The installation of the entire system is exceptionally simple, requires no complex permits and consists only of the inverter, a compatible resistive heating element (200–4000 W) and a photovoltaic array.
  • Panels (typically 400–700 W each) should be connected in series or series-parallel using standard MC4 connectors so that the system open-circuit voltage (Voc at 25 °C) falls within the optimal range of 120–300 V.
  • Technical specifications:
  • DC input voltage: 120 V to 350 V.
  • AC output voltage: RMS 120 V to 250 V (modified sine wave, 50 Hz).
  • Maximum power and current: 4000 W / 16 A.
  • Efficiency: > 97 % (with integrated MPPT function).
  • User interface: Informational LCD display (shows voltage, current, power and production statistics in kWh).
  • Connectivity: 1x set of DC MC4 input connectors, 2x AC type E output sockets.
  • Supported loads: resistive only (device does not support capacitive or inductive loads).
  • Protection features: short-circuit, overload, overvoltage and thermal protection (80 °C).
  • Cooling and enclosure: active automatic cooling, IP21 ingress protection rating.
  • Operating temperature: -25 °C to 55 °C.
  • Construction: durable aluminum housing.

  Please note that installation and dismantling of solar panels and solar accessories must be carried out by a qualified person.
