SOLSOL offers cutting-edge technologies from various manufacturers, tailored to meet a wide range of needs and applications.
Why invest in C&I BESS?
- Backup during outages: Selected systems offer backup capabilities.
- Maximized use of PV systems: Surplus energy is stored and used later.
- Opportunity to trade on the spot market: System flexibility = a new revenue stream.
- Energy independence: Stability even during crises and grid fluctuations.
- Peak shaving: Reducing peak power consumption from the distribution grid with battery support lowers reserved capacity and thus fixed electricity costs.
Commercial C&I battery storage systems enable not only efficient management of self-consumption but also active participation in the modern energy market.
All solutions purchased from us come with a 10-year product warranty included.

Why is energy self-sufficiency essential?
Energy self-sufficiency means independence from volatile electricity prices and reliance on external suppliers. For businesses, it’s a strategic advantage—providing protection against grid outages, regulatory changes, and market fluctuations. It enables predictable cost planning, operational stability, and puts control firmly in your hands.
In an era of geopolitical uncertainty and energy transition, it’s a critical step toward both competitiveness and sustainability.
With a commercial battery storage system from SOLSOL, you're investing in certainty.
Take control of your energy, maximize your return on investment, and get ready for what’s next.
