Save the midday sun for dinner time
Without a battery, a home directly uses 35–50% of what its panels produce. The rest goes to the grid and is compensated at a much lower price. With a battery, self-consumption can exceed 75%.
01
Reserva batteries
- LFP chemistry (lithium iron phosphate): safer and longer-lasting.
- Modular: start with 5.12 kWh (Reserva 5) and grow to 20.48 kWh by adding modules.
- 6,000 cycles at 90% depth of discharge.
- 10-year warranty.
- Backup during outages for the circuits you choose (with the backup kit).
- Installed in half a day on Lumen H5/H8 inverters. Compatible with other hybrid inverters after review.
Does it pay off?
Almost always, if you use more than 3,500 kWh a year, you're home in the evenings, or you already have panels and export more than 40% of what you produce (SolarisTrack shows you).
Example: a home in Paterna with 5.4 kWp installed in 2021 added a Reserva 10 in 2025. Self-consumption went from 41% to 79%. Extra savings: €360/year. Cost: €4,950 installed.
