What is a Solar MPPT PCU?

Where there is a power shortage and power cuts happen in those areas people prefer to install solar panels with storage solutions so that if the power goes then the solar power can be utilized and there is no power break. Also, in the areas where the peak power tariff is higher compared to the normal power tariff there also solar storage solutions are required to save electricity costs.

  • A Solar MPPT PCU acts as the heart of your solar energy storage system. It does the following:
    • Converts DC to AC: Takes the direct current (DC) power generated by solar panels and converts it into the alternating current (AC) form used by your appliances.
    • MPPT Technology: Maximizes solar power extraction by continuously adjusting to find the optimal voltage and current for your solar array, even in varying light conditions.
    • Why the Tubular Lead Acid Battery fails in Solar PCU in two years: The Solar MPPT PCU is designed to fully charge the battery once the solar is available and give the power back to the load and switches off the grid supply. The battery takes time to charge as the Lead Acid battery can’t be charged fast.
    • First Challenge is fast charging: The major challenge faced by the industry is fast charging which is started by the Chinese companies initially and followed by Indian manufacturers blindly. The Solar Charge controller has to limit the charging current according to the battery type and size. The solar charge controller will act as a conduit of solar panel power, and it will not stop the solar power in the case of Solar PCU. The Solar power coming from the solar panels will straight away go to the battery attached to the Solar PCU system unless it’s a completely off-grid system where there is no power available. So, the capacity of the solar charge controller has to match the type of battery and size of the battery attached to it.
    • Let us take an example of Tubular batteries being used for Solar power backup systems in India. The Tubular Lead Acid battery can be charged at 10 per cent of its capacity only. If we install a 200 Ah Tubular lead Acid battery into the system, then we need to restrict the charging current by 20 Amps into the battery so the solar panels we can install with the single panel is 12X20= 240 Watt. So, one can use the Solar charge controller to the capacity of 25Amps or a maximum of 30 Amps, but people install 60 to 80 Amps solar charge controllers inside the solar PCU which becomes the major cause of Tubular Lead Acid battery failures in the solar system. Not only do they fail in the first year or a maximum of two years the batteries are exploding, and major accidents are happening. Lead Acid battery Explosions

Why Choose Lithium Batteries for Solar Systems?

  • Longevity: Lithium batteries boast a longer lifespan than traditional lead-acid batteries, often lasting several years longer. The Lead Acid battery life is 2 to 3 years in the case of Lithium-ion battery it’s 7 to 10 years.
  • High Cycle Life: They can withstand more charge and discharge cycles, making them ideal for regular energy storage and release.
  • Superior Depth of Discharge (DoD): Lithium batteries can be safely discharged to a much greater percentage of their capacity without damage, providing you with more usable power. The Lithium battery comes in C1 capacity and the Lead Acid battery comes in C20 capacity package.
  • Faster Charging: Lithium batteries typically charge faster than their lead-acid counterparts. The Lithium can be charged at 50% or 100% of its capacity so can be charged in 1 to 2 hours whereas the Lead Acid battery can be charged at 10% of its capacity only which will take 10 to 12 hours minimum to charge the complete Lead Acid battery which is the major challenge in the solar storage solutions.
  • Maintenance-Free: Lithium batteries are maintenance-free, and Lead Acid comes with a lot of maintenance challenges like refilling battery water and cleaning etc. On top of it produces poisonous Lead Acid fumes which are harmful to the environment and people at large.
