Solis: Storage of Solar Energy In The

Event of Blackouts

Solis, a leader in solar PV string inverters worldwide, promotes the adoption of hybrid solar systems with storage. This solution enables uninterrupted supply of electricity to homes and businesses that will not affect their operations in the event of a grid supply failure or blackout

According to the latest report issued by the World Bank and other international organizations, there are still 840 million people living in an electricity-free environment globally. 96 countries have not achieved 100% power supply, most of which are located in South Africa and Central, Southern Asia. Electricity prices are rising in most parts of the world, for example the cost of electricity in almost all European countries has continued to rise over the past 10 years. In 2019, the average electricity price for European residents was 20.5 Euro cents/kWh, which is 19% higher than the average price of 16.8 Euro cents/kWh 10 years ago. Australian electricity prices have risen by an average of 75% over the past 10 years and continue to increase. In addition, global natural disasters, such as floods, blizzards, typhoons and polar cold waves are becoming more frequent. These problems are a threat to fragile power grids and can cause blackouts. Across the world installing solar + storage is becoming a lifeline to many properties where grid failures are common.

Hybrid solar PV systems, unlike conventional solar installations, which send the excess energy
generated to the national electricity grid, sends the solar energy to lithium batteries that are
responsible for storing it to be used at night or in an emergency. There is also the possibility
of updating an existing solar PV system to include energy storage by utilizing a specific
inverter for this purpose. Among the benefits of adding energy storage to a solar PV system is:
1) Maximize self-consumption: You can use most of the energy produced by solar panels to
power your daytime energy demand and at the same time charge a battery to use at night.
2) Reliable and clean energy: Energy is generated from the sun, free of charge. Besides that,
this energy does not pollute the planet.

3) Cost reduction: When drawing energy from the grid, the intelligent hybrid inverter can be
programmed to only consume from the grid and charge the battery in low-cost periods.
4) Safety: There are many reasons why the power grid can fail unexpectedly, but with a battery
powered system, you can maintain your power supply to critical loads such as refrigerators.

The functionality that inverters offer should be carefully reviewed prior to system design and
installation, as they are essential in the success of PV installations with battery storage. It is

critical to note that a successful storage solution must feature grid-compatible inverters and
batteries. The compatibility of the battery to the inverter is of equal importance – the inverter
you choose must be paired with a relevant compatible battery. The solar hybrid inverters from
Solis are a reliable and flexible option, backed by many successful installations globally. These
smart hybrid inverters can be programmed in four different modes to maximize the above
benefits. Solis offers both hybrid inverters for new installations and “retrofit” AC coupled
solutions to upgrade existing solar PV systems. Both of which are grid tied solutions..
“This type of technology is revolutionizing the traditional power supply system since it gives
the user the power, security and independence to generate, store and consume their own
clean energy, thus reducing their dependence on the grid and traditional generating plants”.
said Solis Product Director Kun Zhang.
