TCK Solar introduces the new Bosch BPT-S 5 Hybrid solar power storage tank designed to store solar power generated during the day for use at night.

Storage problems associated with solar power mean that late-night power usage relies on the grid at higher consumption rates. Conversely, any power contributed to the grid during the day earns the homeowner about 25% of the late night energy price. Solar power systems have been unable to serve as a completely independent power source for homes.

Bosch’s new BPT-S 5 Hybrid solar power storage tank helps homeowners and users of solar power systems create their own energy source. Functioning as the system inverter, or complementing the existing inverter, the Bosch Hybrid serves as an intelligent energy management system. During the day, the BPT-S 5 generates and distributes power inside the building, using any power not used immediately to charge the high performance lithium-ion batteries. Once the batteries are fully charged, any excess supply will be sold back to the public grid at market tariff.

When the sun goes down, household power is drawn from the storage system till all the energy is completely drained; the energy source will then switch to drawing power from the public grid. The entire process is controlled by Bosch Hybrid independently to ensure continuous supply of energy at a much lower cost than before.

Depending on the model, the lithium batteries can store between 2.2 and 6.6 kWh with one hour of sunshine required to fully charge the storage system.

The BPT-S 5 Hybrid solar power storage system allows multiple appliances to be operated simultaneously in the home with the lithium-ion batteries immediately covering the required power with 5kW. Lithium-ion batteries offer impressive performance, lasting 7,000 charge and discharge cycles, or about 20 years.

Bosch also offers the standard 10-year warranty (upgradable to 15 years on the batteries) for long-term peace of mind.
