CONSTRUCTION OF THE PV PROTECTOR BOX ..........operation. From the beginning of TECHNICAL DATA ....................our company’s operation, we have 5.1. Components of the PV PROTECTOR BOX: ............placed great emphasis on the design 5.1.1. Flow Electric Heater ................of our products.
While using the device, always comply with applicable regulations and health and safety standards. 1. SAFETY SYMBOLS The safety symbols and warning signs shown below are used to emphasize particularly important information regarding safety and proper use of the PV PROTECTOR BOX: SYMBOL MEANING Immediate danger! Failure to comply may result in death or serious bodily harm.
3. DESCRIPTION AND APPLICATION PV PROTECTOR BOX is a flow-through electric water heater activated when the grid voltage exceeds 253V. The device is designed to heat water and prevent the inverter in a PV installation from shutting down in cases where the voltage on any phase exceeds 253V. If the grid voltage exceeds 253V, the system activates a contactor that switches on the electric heater on the phase where the voltage was exceeded and also activates the circulation pump.

PV PROTECTOR BOX DHW TANK SUPPLY FROM WATER MAINS BUFFER TANK 1 HEATING CIRCUIT Diagram of an example connection of the device to the central heating system (C.O.) for a DHW tank with a dual coil configuration. The diagram illustrates the recommended hydraulic components installed outside the device to ensure proper operation.
5.1.1. Flow Electric Heater The flow-through electric heater used in the PV PROTECTOR BOX is a heater with a maximum power of 6 kW, consisting of three independent 2 kW heating elements, powered by a three-phase 230V~ supply. Each heating element is switched on via the current circuit of contactors K1, K2, and K3.
5.1.2. Pressure Sensor The water pressure sensor is installed in the heating medium circuit after the flow heater. When the heating system of the device is filled with water and the pressure rises above 1 bar, the safety circuit contact of contactor K4 closes, allowing it to control the electric heater contactors (K1, K2, K3).

VOLTAGE CONTROL RELAY ON/OFF INDICATION Voltage Control Relay OFF: LED Display - Alternates between "LU" and the current voltage, e.g., 243. Indicator Light - Red LED "FAULT" is lit. Status - Heating contactors K1, K2, K3 are OFF. Voltage Control Relay ON: LED Display - Shows the current voltage, e.g., 253. Indicator Light - Green LED "POWER" is lit. Status - Heating contactors K1, K2, K3 are ON.

TECHNICAL DATA: PARAMETER UNIT VALUE Supply Voltage 12V DC Power Consumption <3 Temperature Measurement Range °C -50 to 99 Measurement Accuracy °C ± 0,1 Nominal Relay Current Temperature Sensor The user can configure 4 parameters: F1 - Temperature setting F2 - Hysteresis: 0.3°C – 10°C F3 - Relay activation delay (LED blinking): 1 to 10 minutes F4 - Temperature sensor calibration: -10°C to 10°C When the temperature exceeds the set value (F1 + F2), cooling is activated, and when it drops below the set value, heating is activated.
When the temperature is within the permissible measurement range, the controller will return to normal operation mode. 6. PODŁĄCZENIE ELEKTRYCZNE PV PROTECTOR BOX is equipped with a complete hermetically sealed electrical switchboard TH-18. The switchboard includes N and PE terminal blocks, circuit breakers, voltage monitoring relays, electromagnetic contactors, a time relay, and a 230V/12VDC power supply.
All pipe connections are leak-free, and the water circuits are properly filled and vented. The 3 x 230/400V~ power supply to the electrical switchboard is connected, and the PV PROTECTOR BOX is powered via an AC type residual current device (RCD) with a 30 mA rating.
9. INSPECTION AND MAINTENANCE External parts can be cleaned with a damp cloth and commercially available cleaning agents. Do not use any abrasive cleaning accessories or solvents to clean the device. In hospitals and other public buildings, applicable regulations regarding cleaning and disinfection must be followed.
