Easy access to your own storage with the PLENTICORE BI 

Retrofitting an existing photovoltaic system with a storage unit offers you various advantages. It allows you to do the following:

  • Increase your self-consumption
  • Reduce your electricity costs
  • Use the solar power that you have generated around-the-clock

 

Why does it make sense to retrofit a power storage unit?

Photovoltaics are a safe, renewable and sustainable source of energy. However, this solar power can only be used when the sun is shining. So what happens after the sun goes down?

Use your self-generated electricity even then by retrofitting a storage unit. Today's storage systems are sophisticated and very inexpensive. With an electricity storage unit, your solar electricity is stored during the day so that you can use it in the evening, even after sunset. This increases your self-consumption and reduces your electricity costs because you have to purchase less electricity from the grid operator. A storage system allows you to become less dependent on your energy supplier. With the PLENTICORE BI in combination with a high-voltage battery, you can always use the sun's energy, up to 24 hours a day!

Comparison of power generation and consumption with and without storage

Save on electricity costs with the most efficient 3-phase AC battery inverter

Up to approx. €1,086 saved per year when using the PLENTICORE BI 5.5 with the BYD battery storage H11.5 as described in the HTW Berlin's latest Energy Storage Inspection. With an SPI of 89.7 %, this combination offers maximum system efficiency for three-phase AC inverters.
The study identifies the System Performance Index (SPI), an economic value that allows the interaction of the components (inverter/battery
/PV modules) available in the complete system to be compared, which creates more transparency for the customer.
As well as offering potential savings on electricity costs, efficient storage systems also contribute to climate protection. After all, reducing CO2 emissions depends largely on the efficiency of the system. When choosing your storage system, you should therefore consider not only the individual components, but also how the inverter and battery interact because efficient systems allow storage losses to be kept as low as possible.
