Self-determined energy supply

Energy without sun

With our solar power storage systems, you create maximum supply independence and can live as self-sufficiently as possible. Electricity storage (also solar storage or battery storage) stores the surplus electricity of the solar systems and makes it available in the household when the sun is not shining.

Using solar energy intelligently

Types

AC-coupled systems have their own battery inverter and are connected to the house grid independently of the PV system.
Hybrid systems, or ESS, are electricity storage systems with an integrated inverter.
DC-coupled electricity storage systems are installed between the PV modules and the inverter on the direct current (DC) side of the solar system.

Optimal memory size

The optimal storage size depends on a variety of individual factors. The size of the PV system, the expected electricity production, the electricity consumption and the consumption behavior are relevant. We calculate the exact capacity for your plant.

Promotion

With the funding product "Renewable Energies - Storage (275)", KfW supports the use of stationary battery storage systems in connection with photovoltaic systems. The subsidy consists of 2 parts:
1. a loan from 1.1 % eff. annual interest rate
2. a repayment subsidy from funds of the Federal Ministry for Economic Affairs and Energy.
