• Product description

  • The ECO Solar Boost EVO MPPT-4000 solar inverter delivers a modern, highly reliable solution for direct water heating and space heating using solar energy, entirely without the need for grid connection (off-grid) or costly battery purchases.
  • Thanks to an enhanced architecture developed with the support of artificial intelligence (AI) and an innovative MPPT algorithm, the inverter intelligently maximizes energy harvest from photovoltaic panels even in low-light conditions such as sunrise and sunset.
  • The unit provides up to 4000 W and 16 A, making it ideal for powering purely resistive appliances — from water heaters and thermal storage tanks to electric radiators, direct heaters, heated mats, and infrared heaters.
  • A major advantage of this model is its dual output in the form of two standard type E (with earth pin) sockets, operating on a priority-switching principle.
  • The system primarily heats the device 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 indicates the condition via LED indicators.
  • Important connection notice: While the priority Output 1 is universal and can accept 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.
  • System installation 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) can be connected in series or series-parallel using standard MC4 connectors so that the system’s open-circuit voltage (Voc at 25 °C) falls within the optimal range of 120–300 V.
  • Technical specifications:
  • Input voltage (DC): 120 V to 350 V.
  • Output voltage (AC): 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).
  • Connectivity: 1x set of DC input MC4 connectors, 2x AC output type E sockets.
  • Supported loads: resistive only (the device does not support capacitive or inductive loads).
  • Protection functions: short-circuit, overload, overvoltage and thermal protection (80 °C).
  • Cooling and enclosure: active automatic cooling, IP21 ingress protection.
  • 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.
