1. Leave enough margin for the inverter
Usually 48V Off Grid Solar Energy Storage Power System is a power supply system for specific loads. During the design process, the rated power of the load connected to the system should be calculated and checked, and the output of the inverter used should be determined according to the total power of the load. Power, fully consider the inrush current, starting power and reactive power that some special loads need at startup, which may affect and demand the inverter, and leave enough margin for the inverter. Once the capacity of the inverter is determined, the capacity of the connected load cannot be expanded or increased at will, so the off-grid photovoltaic power generation system should leave enough margin for the inverter.
2. Fully consider the matching of various loads and inverters
The 48V Off Grid Solar Energy Storage Power System should fully consider the matching of various loads and inverters, especially if there are inductive loads such as washing machines, refrigerators, air conditioners and other inductive loads with motors, they must be selected and equipped. Sine wave or quasi-sine wave inverter to meet the demand of inductive load for inverter output waveform.
3. Calculate the daily average working time and electricity consumption of each load
The 48V Off Grid Solar Energy Storage Power System designs the capacity of the photovoltaic array and the capacity of the battery according to the customer's needs, so as to meet the user's electricity demand and control the overall investment cost.
4. The design is based on the amount of solar radiation in the worst month of the year
The 48V Off Grid Solar Energy Storage Power System needs to ensure the least amount of radiation, and the photovoltaic system can still guarantee power supply. Therefore, the 48V Off Grid Solar Energy Storage Power System usually designs the inclination angle of the photovoltaic array according to the optimal inclination angle of the worst month. That is to say, the array inclination angle of the 48V Off Grid Solar Energy Storage Power System is usually 2° to 8° larger than the local geographic latitude angle to take into account the weaker solar radiation in winter.
