Frequently Asked Questions

Can the system be expanded?

Yes, the Felicity system is modular and allows multiple batteries to be connected in parallel to increase capacity. The Solis inverter supports expansion, as long as configuration values remain within the inverter’s limits.

Does it provide backup power during outages?

Through the EPS output, selected circuits such as lighting, refrigeration and communication remain powered during grid failures. Backup time depends on consumption and available battery charge.

Can it operate without solar panels?

Yes, the system can charge from the grid, making it ideal for dynamic tariffs. Charging during low-price hours and discharging during peak hours helps reduce energy costs even without PV.

How much can I save?

Savings depend on consumption patterns. Households typically reduce evening grid usage significantly. With dynamic tariffs, savings can increase further by time-shifting consumption.

What is the expected lifespan?

The Felicity battery delivers over 6,000 usable cycles, corresponding to many years of daily use. The Solis inverter has a long operational lifespan with minimal maintenance.

What about noise levels?

The Felicity battery operates silently. The Solis inverter has minimal fan noise, typically only audible at close distance during high load or charging periods.

Where should the system be installed?

Common locations include garages, utility rooms or technical spaces. The IP65 rating of the battery allows protected outdoor installation if required.

Is the system compatible with current grid regulations?

Yes, when installed by certified technicians according to NEN1010/NEN3140 standards, the system fully complies with Dutch safety regulations and grid operator requirements.

Can I monitor the system?

Monitoring is available via WiFi and mobile app, offering insight into production, battery state, consumption and export levels.
