A system sized as a whole
We design the panels, inverter, battery, protection and monitoring as one system. Capacity and output are based on how you use energy.
Installation and configuration · Catalonia
Home batteries tailored to your needs.
Already have solar panels, or planning an installation? We review your consumption, inverter and available space before recommending and configuring a battery for your situation.
Backup during an outage requires compatible equipment and defined circuits; we check this as part of the assessment.
Three scenarios
The battery system is designed around your needs
Check compatibility before integration
We check the inverter make and model, its configuration, the electrical diagram and available space. Depending on the system, it may be possible to keep the existing equipment or make changes.
Choose priority circuits
We define priority circuits and check output, capacity and the transfer system. Backup duration depends on available energy and actual consumption.
What we check before recommending a battery
Compatibility, consumption and loads
The initial enquiry helps us understand your situation. We make a recommendation and prepare a proposal after reviewing the required technical information.
- Total consumption and when energy is used.
- Solar generation and surplus, if panels are already installed.
- Inverter make, model, output and configuration.
- Available space, ventilation and cable routes.
- Main goal: self-consumption, tariff management, backup or a combination.
- Output needed for the loads that must run at the same time.
- Possible future additions: solar panels, an electric vehicle or a heat pump.
Power and capacity, explained simply
kW, kWh and selected loads
kWh indicates how much energy a battery can store and helps estimate how long it can power specific loads. kW indicates how much power it can deliver at once and limits which appliances can run simultaneously.
A sound proposal considers both figures and a realistic list of loads. Backup duration cannot be promised as a fixed figure without knowing consumption.
Backup: clear limits
A battery on its own does not keep a home powered during an outage. The system needs a compatible design, safe separation from the grid and a setup for the selected loads.
How it works
A battery is part of a system.
During a grid outage, only circuits included in a backup design can continue to receive power. We verify this before making any claims about backup duration.

Indicative scope
What the service may include
The final scope is tailored to the project and confirmed in the proposal.
Check compatibility
Initial review, technical information and compatibility checks.
Sizing with clear assumptions
Capacity, output, equipment, protection, work and exclusions.
Configure and explain
Installation, configuration, app setup and backup testing where included in the agreed scope and supported by compatible equipment.
Frequently asked questions
Decisions to make before sizing
Can I add a battery to my existing solar panels?
It depends on the inverter, configuration and goal. We check the model, system diagram and available space before recommending whether to keep or change equipment.
Will a battery keep my home powered during an outage?
Only if the system includes a compatible backup function and is designed for the selected loads. A battery connected for self-consumption does not by itself guarantee power during an outage.
How much capacity do I need?
It is calculated from consumption, usage times, solar generation, tariff and backup goals. We do not use one figure for every home.
What is the difference between a physical battery and a virtual battery?
A physical battery stores energy at home and, with a suitable design, can be part of a backup system. A virtual battery is a commercial billing arrangement; it does not store energy at home or power loads during an outage.
What warranty does it have?
The equipment warranty depends on the manufacturer and model. The proposal identifies the terms that apply to the equipment and the included work separately.
Next step
Assess my system
Tell us whether you already have panels and what you want to achieve: use surplus energy, add a battery or provide backup during outages.
Request an assessment
We use this information for an initial review. Before recommending a battery, we will check consumption, existing equipment, photos and the loads you want backed up.
