The Input Voltage on our smaller Solar Generator is generally 30A/120V. The Diagram above is for setting up a 60a/120v-240v solar generator to your breaker package. There was another website available that shows the Diagram that is wiring for a 30A/120V Solar Generator to your breaker package. Never forget, the Portable Generator comes with additional outlets from the region of the generator that is portable linking equipment or devices right to the Solar Generator. The Solar Generator is very simple to work.
