How is a Solar Power Conditioning Unit Different from a Regular Inverter?

A solar power conditioning unit basically contains parts like a solar charger, battery mechanism, output selector mechanism, control algorithm, grids (main utility) charger as well as an inverter. It functions as an integrated system which gives the user the facility of charging the battery through either solar power or a grid/DG set.Getting a power inverter for home would be enough to meet all the requirements of energy.

Each unit of the PCU functions to improve efficiency and performance. The solar charger, using either PCM or MPPT technology, is the device that converts the received solar energy and charges the battery. The inverter plays the role of converting the stored DC voltage in the battery to SC power to the required output voltage. The grid charger is used when solar energy isn’t available and through it, energy from the grid can be used for charging the battery.The selector mechanism is the relay that makes it possible to prioritize solar energy and make sure grid energy is used if the solar energy is exhausted. The control algorithm also sets the PCU apart from a normal invertor by prioritizing and selecting the source of charging the battery. The battery bank stores the solar charger for another usage.

Basically, the solar inverter is a device that prioritizes solar charging although it does avail of an option where even if the battery is charged through solar during the day, in the presence of a mains facility, the load will be fed through the mains itself by using the bypass mode. The inverter mode of the battery allows for the solar energy that was stored in the battery to be used when the AC mains are absent. As long as the electricity needs are being met through the mains, the solar power remains stored within the battery itself. This way, there is no leakage of the energy that was received and it is used to its full efficiency. The solar inverter price for home is quite affordable as well.

As with the inverter, the solar power conditioning unit (PCU) also prioritizes the solar charging of the battery during the solar day. Until the full charge voltage of the battery is reached, the charging of the battery is continued. This is generally 14.2 V for a small inverter battery. Once the full charging is completed with the battery, then the electricity load is fed using the battery that is in inverter mode. This means that AC power will not have to be used in the presence of solar power. Only once the battery becomes fully discharged – which happens till around 11 V generally – does the mains take the over-charging and then begin to feed the load as well. This system makes sure that the mains energy is used to feed the load only once the solar energy is completely finished and in any other case, the use of solar energy remains the priority. Hence, a home inverter with battery price is affordable and worth it.
