Page 18: Photovoltaic Connection
User Manual POW-RELAB SERIES DANGER ⚫ Before connecting the battery, it is essential to disconnect the circuit breaker to avoid the risk of electric shock. Do not perform any operations while the power is on. ⚫ Ensure that the positive and negative terminals of the battery are correctly connected and not reversed, as this could damage the inverter.
Page 19 User Manual POW-RELAB SERIES DANGER ⚫ Before connecting the photovoltaic panels, it is essential to open the circuit breaker to avoid the risk of electric shock. Do not perform any operations while the power is on. ⚫ Please ensure that the open-circuit voltage of the connected photovoltaic modules in series does not exceed the maximum open-circuit voltage of the inverter (which is 150V in the POW-RELAB-SPLIT series), as otherwise, the inverter may be damaged.
Page 20 User Manual POW-RELAB SERIES ⚫ In any scenario, the total output power is equal to the power of a single photovoltaic panel multiplied by the total number of panels. The guideline for configuring photovoltaic panels is that the total power should be equal to or slightly greater than the maximum allowable PV power of the solar controller (refer to the technical specifications table).
