Power Storage – achieve a zero usage power bill!

The most common challenge with solar is that it generates power during the day, when most people are at work.

Wouldn’t it be great if you could store the energy your solar system generates during the day, so you can use it at night? Now you can!

Centsible Energy is thrilled to be a supplier of the Phonocube.

The Phonocube is  an energy management unit that combines the inverter, batteries and the photovoltaic system into one compact system. It can be integrated in both new and existing photovoltaic systems.

Phonocube makes it possible for solar system owners to use PV electricity for their own requirements at times of less light; in the morning or evening.

Electricity produced by your system can be consumed directly, stored in the batteries or fed into the public grid. Phonocube prioritises your own energy consumption needs – grid power will only be used when the solar system nor the batteries are able to supply sufficient electricity.

How it works:

phono_img_88Morning Energy produced by the PV system (1) is used to optimize self-consumption.

Excess energy is used to recharge the batteries (3).




When the batteries (3) are fully charged and Phonocube is already meeting your self-consumption requirements

Excess energy is fed into the public grid.



Once the sun has set, the system automatically switches to energy from the batteries (3).




If the battery (3) capacity is insufficient to meet your consumption requirements.

Electricity is then obtained from the public grid.
