SMA Solar Inverter & Battery Compatibility – Installer Procurement Guide

A complete SMA solar energy storage installation must use components approved for the exact architecture.

Compatibility depends on more than the SMA brand name.

SMA Battery Compatibility Matrix – Main Platforms

What Must Installers Verify?

1. Exact inverter model and hardware generation
2. Battery model and battery module generation
3. Battery nominal and operating voltage
4. Battery management communication
5. Inverter firmware
6. Battery firmware
7. Minimum battery module quantity
8. Maximum battery module quantity
9. Permitted charging and discharging current
10. Battery discharge power
11. Backup power requirements
12. Parallel inverter restrictions
13. Monitoring and metering equipment
