Solar Battery Service in Mallorca

Battery storage is at the heart of many self-consumption and off-grid systems. Kreuzer provides diagnostics, maintenance and technical support for existing solar batteries in Mallorca, whether the cause lies in the battery, communication or inverter.

Typical solar battery problems

• The battery does not charge or discharge as expected
• Usable capacity or runtime has noticeably decreased
• Communication faults between battery and inverter
• Warnings, shutdowns or implausible state-of-charge readings
• Cell voltage differences or balancing problems

Diagnostics before replacing parts

We review event logs, voltages, temperatures, charge limits and communication across the complete system. Only then can we determine whether settings need correction, modules require testing or components must be replaced.

Maintenance and preventive checks

For older or heavily used systems, we inspect connections, environmental conditions, firmware and operating data. Findings are documented so that developing faults can be recognised early and expansions planned realistically.

Brand-specific service and expansion

For brand-specific diagnostics and technical support, see our BYD Battery Service and Pylontech Battery Service. If the existing capacity is no longer sufficient, our Battery Expansion & Retrofit service checks whether additional modules are technically compatible and economically sensible.

Request solar battery service

Send the manufacturer, model, age, number of battery modules, inverter type and exact error message. Photographs of rating plates, displays and the installation help us make an initial assessment.
