Tools & Calculators
Voltage Rise Calculator
Estimate voltage rise for solar inverter cable runs using a mobile-friendly calculator built for Australian installers.
This calculator is provided as a guide only. Cable values must be verified against the applicable AS/NZS standards and site-specific design requirements. Cable current ratings, installation conditions, protection, derating and compliance checks are not assessed.

PV String Calculator
Enter the solar module specifications from the datasheet to calculate a recommended string configuration for the configured MPPT inputs.
This calculator is provided as a guide only. Always verify final string sizing against current inverter and module datasheets, site conditions, local standards and installation requirements.
Recommended configuration
Balanced string layout across the configured MPPT inputs.
Optimal configuration
This string layout sits within the configured voltage, current and PV power limits.
Important considerations
Review cold-weather Voc, hot-weather Vmp, input current, isolator ratings, roof orientation, cable design and local installation standards before finalising the design.
This calculator is intended as a design aid only and should be checked against the current inverter and solar module datasheets.
System Sizing Calculator
Estimate the number of inverter, battery and solar modules required for a modular stand-alone power system.
This calculator provides a high-level estimate only. Confirm final system design and compliance requirements with a qualified designer or installer.
Recommended system configuration
A high-level sizing estimate based on the entered assumptions.
