Performance parameters of High Voltage solar battery

1. Open circuit voltage

Open circuit voltage UOC: the output voltage value of the High Voltage solar battery when the High Voltage solar battery is placed under the AM1.5 spectral condition and the light source intensity of 100 mW/cm2 is open-circuited at both ends.

2. Short circuit current

Short-circuit current ISC: It is the current value flowing through both ends of the High Voltage solar battery when the output terminal is short-circuited when the battery backup solar is placed under AM1.5 spectral conditions and a light source intensity of 100 mW/cm2.

3. Maximum affair power

The operating voltage and current of the High Voltage solar battery vary with the cargo resistance, and the volt-ampere characteristic wind of the LFP energy storage can be attained by making a wind of the operating voltage and current corresponding to different resistance values. However, the maximum affair power can be attained, which is represented by the symbol Pm, If the named cargo resistance value can maximize the productivity of the affair voltage and current. The working voltage and working current at this time are called the stylish working voltage and the stylish working current, which are represented by the symbols Um and Im independently.

4. Fill factor

Another important parameter of High Voltage solar batteryis the filler factor FF (fill factor), which is the rate of the maximum affair power to the product of open circuit voltage and short circuit current. FF is an important indicator to measure the affair characteristics of High Voltage solar batteries. It's a characteristic that represents the maximum power that BMS lifepo4 100Ah an affair when it has optimal cargo. The larger the value, the lesser the affair power of High Voltage solar battery. The value of FF is always lower than 1 series and resemblant resistors have a great influence on the filler factor. The larger the series resistance, the further the short-circuit current drops and the filler factor decreases. The lower the resemblant resistance is, the larger its partial current will be, performing in a drop in the open circuit voltage and a drop in the filler factor.

5. Conversion effectiveness

The conversion effectiveness of High Voltage solar battery refers to the maximum energy conversion effectiveness when the optimal cargo resistance is connected to the external circuit, which is equal to the rate of the affair power of a High Voltage solar battery to the energy incident on the face of High Voltage Lithium Battery. The photoelectric conversion effectiveness of High Voltage solar batteries is an important parameter to measure the quality and specialized position of the battery. It's related to the structure, junction characteristics, material parcels, operating temperature, radiation damage of radioactive patches, and environmental changes of the battery.

Power calculation of High Voltage solar battery

The solar AC power generation system is composed of solar panels, charge regulators, inverters, and batteries. Solar DC power generation systems don't include inverters. To make the solar power generation system give enough power for the cargo, it's necessary to elect the factors nicely according to the power of the electrical appliances. Let's take 100W affair power and use it for 6 hours a day as an illustration to introduce the computation system.

1. First, calculate the watt-hours consumed per day (including the loss of the inverter) if the conversion effectiveness of the inverter is 90, also when the affair power is 100W, the factual required affair power should be 100W/ 90 ≈ 111W; if it's used for 5 hours a day, the power consumption is 111W × 5h = 555Wh.

2. Computation of High Voltage solar battery Grounded on the diurnal effective sun time of 6 hours, and considering the charging effectiveness and loss during charging, the affair power of the solar battery 48v 200ah should be 555Wh/ 6h/ 70 = 130W. Among them, 70 is the factual power used by the High Voltage solar battery during the charging process.
