Battery characteristics of solar inverters

In this article, the solar inverter will be introduced to a certain extent, and I hope it will be helpful to you.

    Solar inverter is a part of solar power system to generate power from solar panels to storage into battery bank , with a backup which works in day and night both, during the day, the solar panel charges the battery.

    To develop a solar inverter system, it is very important to understand the different characteristics of solar battery (PV Battery).  

    The light intensity and temperature can greatly affect the working characteristics of the PV cell of the solar inverter. The current is directly proportional to the light intensity, but the change in light has little effect on the operating voltage. However, the operating voltage is affected by temperature. An increase in battery temperature will reduce the operating voltage, but has little effect on the current generated.

    The influence of light intensity changes on battery output power is greater than that of temperature changes. This applies to all commonly used PV materials. The important result of the combination of these two effects is that the power of the solar inverter PV cell will decrease with the decrease of light intensity and/or the increase of temperature.

Maximum power point (MPPT)

    By continuously increasing the resistive load on the irradiated battery from zero (short-circuit event) to a very high value (open-circuit event), it can be determined that MPPT.MPPT is the operating point at which V x I reaches its maximum value, and under this irradiation intensity The solar inverter can achieve maximum power. In the event of a short circuit (PV voltage equals zero) or open circuit (PV current equals zero), the output power is zero.

    High-quality monocrystalline silicon solar cells can generate 0.60 volts open circuit voltage at a temperature of 25°C. In the case of sufficient light and air temperature of 25°C, the temperature of a given battery may be close to 45°C, which will reduce the open circuit voltage to about 0.55V. As the temperature increases, the open circuit voltage of the solar inverter continues Decrease until the PV module is short-circuited.

    The solar inverter must ensure that the PV module is working at the MPPT at any given time, so that the maximum energy can be obtained from the PV module. Solar inverters can use a maximum power point control loop for this purpose, which is also called a maximum power point tracker.
