- Page 3 INTRODUCTION Thank you for your trust and for choosing our Solar BOOST solar inverter with MPPT. We are confident that the product will meet your expectations. This manual will help you to familiarise yourself with the unit and facilitate the configuration process, as well as help you with any problems that may arise during the operation of the unit.
- Page 4 ABOUT THE PRODUCT The ECO Solar Boost solar water heater inverter with MPPT technology is designed to deliver the electricity generated by the solar panels to the electric water heater with maximum efficiency thanks to MPPT technology. It converts the direct current from the photovoltaic panels into square wave alternating current, which can be directly connected to traditional water heaters.
- Page 5 suitable for heating only heating elements by solar energy, and the load on the controller can be used to connect AC equipment or heaters, heating power 420V/4000 watt range. Characteristics Maximum input power from PV 4000W Solar input current ≤ 20A Solar input voltage range 160 Vdc～420 Vdc MPPT operating voltage range...
- Page 6 The installation environment is critical to the performance and service life of the product. It is recommended that the inverter is installed in a dry environment, protected from water. It is best to ensure sufficient ventilation around the product and adequate airflow. Warning : Never install the device in a closed box! This device cannot be used in parallel! Caution : Risk of damage to equipment!

- Page 10 1. Disconnect AC power source: Make sure the product is disconnected from the mains. Turn off the AC input switch. 2. Disconnect solar panel: Make sure the product is disconnected from the solar panels. Switch off the PV input switch. 3.
- Page 11 2. The AC temperature setting will be displayed. 3. Press the 'enter' key. 4. The maximum water temperature setting number will start flashing. 5. Use the "up" (up arrow) and "down" (down arrow) keys to select the maximum AC temperature (you can choose between 30°C and 80°C).
- Page 12 Recovery: When the voltage drops below 260VAC, the fault indicator goes out and the controller resumes normal operation. 2. PV high input voltage alarm Condition: If the open circuit voltage of the solar cells connected to the controller exceeds the maximum input voltage specified by the device. Risks: The product may stop working or become damaged.
- Page 13 do not open the controller wiring cover. Do not open the controller wiring cover until 5 minutes after the power has been disconnected. Check: That the power cable in the connection box is not damaged due to ageing, friction, insects or small animals. If there is any damage, repair or replace it in time.
- Page 14 The following situations are not covered by the warranty service: Man-made damage such as accidents, negligence, improper installation or misuse. Damage caused by solar cell voltage, power or load current exceeding nominal values. Damage to the controller caused by selecting heaters with excessive specifications.
