String planning for PV systems
Plan PV strings error-free and efficiently. With autarc, you can connect solar modules automatically, easily and flawlessly and check all parameters live. For maximum system performance.
What is string planning?
String planning is the electrical connection of solar modules to strings for connection to inverters. It determines the number of modules, voltage and amperage per module row. Correct string planning maximizes yield and prevents technical problems. Factors such as module type, inverter compatibility, and installation conditions are considered.
How does string planning work with autarc?
autarc automates the entire string planning based on your module assignment. The software calculates optimal string configurations and checks all technical parameters in real time. You will receive immediate feedback on the feasibility and efficiency of your planning. Inverter data is automatically included and individual MPPT settings are taken into account.
- Step 1: Drag & Drop modules
- Step 2: Live testing of all parameters
- Step 3: MPPT optimization
