As more Portuguese households adopt solar power, they are also looking for practical ways to increase solar self-consumption and manage household electricity more flexibly. For this Portugal residential energy storage project, we supplied three 10 kWh wall-mounted batteries with a combined capacity of 30 kWh. We then connected the batteries to the customer’s existing Growatt inverter.
The installation team completed the connection successfully, and the customer reported that the battery system operated normally with the Growatt inverter. As a result, this project demonstrates how a compatible battery solution can upgrade an existing home solar system without requiring the customer to replace the original inverter.
Project Configuration: Three 10 kWh Wall-Mounted Batteries
The project uses three wall-mounted batteries, each with a nominal capacity of 10 kWh. Together, the three units provide a total configured capacity of 30 kWh. This modular arrangement allows the customer to build the required storage capacity with multiple units instead of relying on a single high-capacity device.
In addition, the installers mounted the three batteries neatly along the upper section of the wall. The layout keeps the equipment organized and leaves practical space for operation and maintenance. Because the wall-mounted design uses vertical wall space, it reduces the system’s impact on the floor area. Therefore, it can suit garages, utility rooms, storage areas, and other residential spaces that provide a suitable wall for installation.
For households that need a larger storage capacity, multiple 10 kWh batteries offer a flexible configuration path. However, installers should confirm the final battery quantity after checking the inverter specifications, household loads, installation environment, and applicable local electrical requirements.
Smooth Connection with the Customer’s Existing Growatt Inverter
The project’s main advantage comes from its ability to work with the customer’s existing Growatt inverter. Instead of replacing the original inverter, the installation team matched the battery system, communication connection, and operating parameters with the customer’s existing equipment.
This approach can simplify the upgrade process for homeowners who already operate a solar power system but want to add energy storage. It can also help them avoid replacing equipment that still meets their needs. Before installation, however, qualified technicians must verify the exact inverter model, communication protocol, battery voltage range, system power, and installation requirements.
After the team completed the installation, the three 10 kWh wall-mounted batteries connected normally with the customer’s Growatt inverter. The successful connection met the customer’s requirement to upgrade the existing home solar energy system with additional storage capacity.
Why Portuguese Households Upgrade to Solar Energy Storage
Many households in Portugal already use, or plan to install, residential solar power systems. Nevertheless, solar panels and an inverter alone may not allow a household to use every unit of electricity at the time of generation. A suitable home solar battery can give the household greater flexibility when it manages and schedules its electricity use.
By adding energy storage, homeowners can coordinate system operation with their solar generation profile and daily consumption habits. When the system design allows it, the battery can store electricity generated during the day and make that stored energy available later for household use. The actual energy savings, backup performance, and financial return will depend on several project-specific factors, including local electricity prices, solar capacity, household loads, and the system’s operating strategy.
In this Portugal project, the three 10 kWh wall-mounted batteries provide a total configured capacity of 30 kWh. Consequently, the customer gained more storage capacity for the existing solar system while continuing to use the original Growatt inverter.

Conclusion: A Flexible Storage Upgrade for Existing Solar Systems
This Portugal installation shows that homeowners do not always need to build a home energy storage system from the ground up. Instead, homeowners who already own a Growatt inverter can first confirm the inverter model, communication protocol, and system parameters. They can then select a compatible battery solution that matches their actual storage needs.
For this project, three 10 kWh wall-mounted batteries connected normally with the customer’s existing Growatt inverter. The compact wall-mounted layout also created a clear and space-efficient installation. Therefore, the solution suits households that want to increase storage capacity and improve the flexibility of their solar power system.
