How to choose solar panels for an inverter

Our service helps you figure out how to properly match solar panels to an inverter so that the system works efficiently and safely. The calculations are based on data from official manufacturer datasheets for inverters and panels.

Compatibility of solar panels and inverters

Each inverter has its own solar input parameters: MPPT trackers, voltage range, current and power limitations. The selector takes these characteristics into account for popular models, such as Deye SUN-8K-SG05LP1-EU, Growatt MIN 5000TL-XH, GoodWe GW5000-ES-20, LuxPower LXP-5K, and others.

When selecting panels, models from different lines are analyzed, such as JA Solar JAM72D40-580/MB, Trina Vertex S TSM-500DE09, LONGi LR5-66HIH 505W, Jinko Tiger Neo N-Type 475W, Risen RSM120-8-600M, and others.

Calculation and operating conditions

  • taking into account the minimum temperature of the region of operation;
  • specifying the number of panels in a string and the number of rows (strings);
  • applying current and power clipping to bring the calculation closer to real conditions.

This approach allows you to understand how many solar panels you need for your home in your case and how to calculate the power of solar panels for the required load.

Why use a selector?

  • Quick calculation without manually analyzing dozens of specifications;
  • Comparison of solar panels and inverters to select the optimal solution;
  • Compatibility check of equipment and reduction of the risk of errors in design.

Important

The selector provides informational data. Final decisions should be made based on official manufacturer documentation and the practical experience of installers.

The data may not match your specific situation. If you notice any inaccuracies or would like to suggest improvements, please send them via the “Comments and suggestions” form.
