Battery Expansion & Retrofit
Many photovoltaic systems in Mallorca were installed without battery storage or with insufficient capacity. A battery expansion can significantly increase self-consumption, reduce grid dependency and, depending on the system, enable backup or off-grid functionality.
When does a battery upgrade make sense?
- High grid consumption despite having a PV system (especially evenings / nights)
- Desire for greater energy independence (e.g. finca or holiday home)
- Unstable grid or occasional power outages
- Existing battery system is too small and needs expansion
Is my system suitable for expansion?
In most cases: yes. Key factors include the inverter type, existing protection devices, grid configuration (e.g. TT system) and the intended goal (self-consumption, backup, off-grid operation). We assess your existing installation and recommend a suitable, brand-independent solution.
Which battery systems are possible?
- Modular lithium battery systems (expandable)
- High-voltage or low-voltage batteries
- Hybrid / ESS solutions (e.g. with backup or generator integration)
The system is always selected based on your existing installation and consumption profile – no standard packages.
Specific conditions in Mallorca
- Variable grid quality and long cable runs (fincas)
- High ambient temperatures: correct installation and ventilation are essential
- Optional integration of generator, EV charger or load management
How the process works
- Review of the existing system (photos, datasheets)
- Feasibility and safety / compliance check
- System and battery sizing
- Installation, configuration and commissioning
