What is this tool used for?

Use this tool to screen a proposed panel-string arrangement against the selected voltage and current limits of one inverter MPPT input.

How to use this calculator

Enter series and parallel counts, panel datasheet values and temperature coefficients, design cell temperatures, and the inverter's absolute PV, MPPT operating and current limits. Treat each independent MPPT separately.

Understanding your results

Review every voltage and current check rather than just total array watts. A passing screen covers only the limits modelled here; startup voltage, permitted array power, connector restrictions and manufacturer design rules still need verification.

計算方法

Temperature-corrected voltage = series × reference voltage × [1 + coefficient / 100 × (cell temperature − 25)]. Compare cold Voc with absolute PV maximum; hot and cold Vmp with MPPT window. Compare parallel Imp and Isc with their separate current limits.

使用結果之前

Passing these selected checks is not full equipment approval. Verify startup voltage, permitted array wattage, irradiance/current correction factors, connector limits and manufacturer string-design rules. Inputs describe ONE MPPT, not combined independent MPPT channels.
