What Documentation Installers Need Before Project Handover

Pylontech Force H2 high-voltage stackable battery

Why documentation matters

A well-documented handover reduces callback visits, speeds up warranty claims, and builds installer reputation. Customers who understand their system are less likely to trigger false alarms.

The minimum documentation package

A signed commissioning report, as-built wiring diagram, warranty registration, inverter and battery manuals, a one-page quick reference card, and monitoring login credentials.

Commissioning report essentials

Record PV string voltages, serial numbers, firmware versions, configured grid code, battery settings, functional test results, and installation photos.

Customer education

Walk the customer through the monitoring app, explain normal operating indicators, show them how to read SOC and energy values, and provide a clear support contact.
