Practical mantenimiento tips, common problems and error messages. Keep your batería doméstica in top condition and know when to call in a professional.
The short answer: very little. A modern batería doméstica with LFP cells is designed to last 15–25 years with minimal mantenimiento. There are no moving parts, no fluids to top up and no filters to replace. The battery itself is a sealed system that you do not need to open.
That said, there are a number of simple checks and actions that optimise vida útil and performance. Just like a boiler or car, a batería doméstica also benefits from periodic attention.
Below is a practical schedule with the most important mantenimiento tasks:
Even the best batería doméstica can occasionally experience a fault. Below are the three most common problems with solutions you can try yourself:
Possible causes: The inversor is switched off, the paneles solares are producing insufficient power (cloudy/night), the battery has reached its maximum state of charge, or there is a communication fault. Solution: Check whether the inversor is on and correctly connected. Check the app to see if the battery is already at 100%. Restart the system by switching the battery off for 60 seconds (main switch) and turning it back on. If the problem persists, check the fuses in your fuse box.

Possible causes: Higher temperature in the room (battery cools more actively), cold temperatures (less available capacity), outdated firmware, or early cell degradation in older systems. Solution: Check the ambient temperature — in cold conditions, temporarily reduced capacity is normal. Install the latest actualización de firmware. Check the app for cell balancing issues. For systems older than 8 years: have a professional capacity test carried out.
Possible causes: WiFi connection lost, router restarted, app update needed, or the gateway/dongle has frozen. Solution: Check your WiFi connection and whether the battery is still connected (LED indicator). Restart the WiFi module or gateway. Update the app to the latest version. As a last resort: reset the WiFi pairing via the physical button on the unit and reconnect.
