SUNFLEX: BESS for PV Farms

SUNFLEX is the optimal BESS and PV inverter system in order to sale solar energy on not solar time. The SUNFLEX System could reduce between 5 to 7 % the DC/AC conversion losses, because SUNFLEX BESS is on the DC site and the energy will converter just one time from DC to AC.

Traditional AC BESS

Direct

Indirect

5 to 7% Reduction losses conversion DC/AC process No PV Inverter clipping

SUNFLEX

Mayor income per year

One AC conection assets

Less TR + Cable Capex

One BESS and PV inverter Supplier

Bankability.

Peak Saving BESS for Assets

Discharging BESS Max Power of the Asset

• The peak demand will be achieved by the asset + the BESS and the BESS will be charged by the same asset on the valley time.

Charging BESS

• You shouldn’t increase the capacity or build a new asset if the demand peak will be in a few minutes of the year. Demand

24h

Asset Line

• T&D application need tariff payments rules, but not Industry sector, Industry sector need business case base on the saving.

• The best business case for BESS is when the demand have big peak in short time.

• Assets as transmission or distribution line, Generators and power transformers could be support by Peak saving BESS. © Siemens AG 2018 Page 7
