Felicity 40 kWh Tower +
Solis 15kW 3-Phase
Complete Package

This is a much larger and more powerful system with important differences:

• Capacity: 40 kWh vs 12.5 kWh - more than 3x storage
• Power: 15kW 3-phase vs 5kW 1-phase - 3x more power
• Application: Suitable for large homes, small business and agricultural sector
• 3-phase connection: Required for larger installations and heavier consumption
• Modular: 8 stacked battery modules for maximum flexibility

Yes, for this system you need a 3-phase connection. The Solis 15kW inverter is a 3-phase inverter that delivers 15kW continuous power. This is ideal for:

• Large homes with high consumption
• Commercial buildings and shops
• Farms and agricultural businesses
• Buildings with heavy equipment (heat pumps, air conditioning, machinery)

If you don't have 3-phase yet, this can often be requested from your grid operator (additional costs). We are happy to advise you on this.

The system consists of a battery tower and an inverter:

• Battery tower (8 modules): Approximately 60cm wide × 50cm deep × 180cm high (stacked)
• Solis inverter: 37cm wide × 43.6cm high × 16.5cm deep (wall mounted)

You need free floor space of approximately 60×50cm for the battery tower plus wall space for the inverter. Ideal is a meter cabinet room, garage or technical room with good ventilation.

With 40 kWh storage capacity, the savings are significant. For a large household or small business with consumption of 15,000-25,000 kWh per year:

• Savings: €2,000 - €3,000 per year
• Self-sufficiency: 80-90% with sufficient solar panels
• Payback period: 5-6 years at current energy prices
• Extra benefit: Protection against future price increases

The exact savings depend on your consumption profile, number of solar panels and energy tariff. We are happy to make a personal calculation for your situation.
