Key takeaways
  • Compare entered string voltage and current against documented inverter input limits at the design conditions you supply.
  • What you get: String voltage · voltage headroom · current check.
  • Runs in your browser with no sign-up. Saving a result is optional. An estimate for guidance, not a certificate.

How it works

String voltage is the entered per-module design-condition voltage multiplied by modules in series. The worksheet compares those results and the entered current with the exact inverter limits you supply; it does not calculate site temperatures.

Estimates only: for guidance, not a quote or a compliance certificate. Verify against the current AS/NZS standards and a licensed design. The maths runs in your browser. Nothing is sent to Wattbench unless you sign in and deliberately save the result.
