To configure an efficient Anern solar power system, careful calculations and precise component selection are required. This article will introduce how to configure an Anern solar power systemto ensure efficient operation under various conditions.
The controller's voltage should match the inverter voltage and the output voltage after connecting the solar energy panels. Then configure the controller based on the current. The current size is determined by the power of the solar energy panels. For example, four 200W solar energy panels with a total power of 800W. Assuming the output voltage after connection is24V, then the current is 800W/24V=33A. Therefore, you need to select a24V/40Acharging and discharging controller. Note that the controller's power (voltage × current) should be greater than or equal to the total power of all thesolar energy panels.
The selection of the inverter is determined by the load, which is divided into inductive loads and resistive loads. Inductive loads include motors, fans, pumps, and air conditioners, which have4 to 7 times the surge current when starting. For these devices, calculate power based on at least 4 times the power; resistive loads such as lights, computers, and monitors can be calculated based on their original power. The selection of the inverter should be larger than the maximum amplified power of the back-end equipment. For example, if driving a 1KW water pump and a1KWcomputer, the water pump will have a surge current of more than4times, while the computer will not. Therefore, the maximum required power is4KW+1KW=5KW, so the inverter should be at least 6KW or more.
The choice of batteries depends on the power size of the equipment being driven and the required battery backup time. The system power is the sum of the power of all equipment, excluding surges, as the impact of short surge times on the battery is minimal. The battery capacity formula is: (total power/DC voltage) × hours=the capacity of a single battery; the number of batteries is=DC voltage/single battery voltage. For example, if the total power is2000W, the DC voltage is24V, and it needs to supply power for2hours, the battery capacity would be (2000W/24V) ×2hours=166Ah, requiring two180Ah/12Vbatteries.
Solar panelscharge the batteries. The capacity and voltage of the batteries determine the size of thesolar energy panels. For example, using one100Ah/12Vbattery, if assuming5hours of sufficient sunlight in a day, it requires20Acharging current:20A×12V=240W, so thesolar energy panelsmust be greater than or equal to12V/240W. If the user wishes that in sunny conditions thesolar energy panelscan directly output through the inverter, thesolar energy panels' power should be greater than or equal to the load power, and the DC voltage level should match the DC voltage level of the inverter input.
Following the above steps can ensure that your Anern solar power system runs efficiently and stably.
