First, calculate the required unit power according to the electrical load of the required load. The higher the power, the higher the price. Before bidding and purchasing, be sure to understand clearly and pay attention to the relationship between rated power and standby power. The power of diesel generator set is generally expressed in kVA or kW. KVA is unit capacity, namely apparent power. KW is electrical power, that is, effective power. The factor relationship between the two can be understood as 1kVA=0.8kW. It is recommended to design clear power load requirements before purchase.

The effective power kW is generally recommended. Before bidding procurement, it is necessary to communicate with the electrical designer to confirm that the same concept is clearly defined in the design drawing description, technical specification and quotation. Unit power. In the process of communication with the technology and suppliers, the expression shall be made according to the same power, and the corresponding equipment shall be specified, so as to avoid the appearance of the equipment and the configuration of the equipment are insufficient to meet the design requirements, or the unit equipment exceeds the requirements, which wastes the cost.
