Empowering Iberian Homes with Smart Energy Storage: Residential Battery Projects in Spain & Portugal

As solar adoption accelerates across Southern Europe, more individual homeowners are turning to smart energy storage systems to gain energy independence, reduce electricity costs, and prepare for grid instability. In Spain and Portugal—two countries blessed with abundant sunshine—we've supported several residential customers in building custom battery backup systems designed for reliability, flexibility, and long-term efficiency.

Here's a look at three recent projects that reflect the growing demand for solar battery solutions (baterías solares para casa) in the Iberian Peninsula.

1️⃣ Spain: Full Home Backup System with Wall-Mounted Batteries & Hybrid Inverters

A Spanish homeowner chose to future-proof their home with a complete solar battery storage setup, integrating:

· 3 × 10kWh wall-mounted lithium batteries

· 2 × Growatt hybrid inverters

This configuration provides 30kWh of backup capacity, sufficient to meet all household electricity needs during the night or grid outages, including appliances, lighting, and essential electronics. By integrating efficient Growatt hybrid inverters, the homeowner enjoys seamless energy switching, app-based monitoring, and significantly reduced electricity costs.

2️⃣ Spain: System Upgrade with 3 × 15kWh Gaia Series Batteries

Another customer in Spain upgraded their existing battery storage by replacing two older 10kWh models with three 15kWh Gaia Series batteries, totaling 45kWh of high-efficiency lithium storage.

· Increased usable energy capacity

· Longer cycle life and better thermal management

· Enhanced compatibility with their existing inverter

The new system ensures greater autonomy during periods of peak electricity pricing and grid instability. This is a perfect example of how TERLI can meet diverse customer needs for battery energy storage systems—delivering higher load coverage without compromising battery lifespan. It showcases how residential solar users can scale up their storage capacity to meet increasing energy demands.

3️⃣ Portugal: 10kWh Off-Grid Solar System with Yellow Face Inverter

In rural Portugal, where grid access is limited, a homeowner installed a fully off-grid 10kWh lithium battery system, paired with a new-generation inverter with yellow front panel. This self-sufficient setup powers their lighting, refrigeration, and internet connectivity—all from solar energy alone.

· Essential home appliances

· Lighting and Wi-Fi routers

· Backup loads during cloudy days

The compact design makes it well-suited for rural installations, providing a reliable off-grid energy storage solution for budget-conscious consumers. As a result, diesel generators are no longer a sustainable or cost-effective option.
