ACS Configuration Considerations
30 Prosine 2.5/3.0 Installation & Operation Guide
AC (Shorepower) Configuration
Only one configurable parameter is found in the AC Information menu: breaker size. An AC circuit
breaker must be installed in the AC supply circuit (shorepower) leading to the Prosine inverter/
charger. Specifying the size of the breaker in the AC Information menu reduces ‘nuisance’ tripping of
the supply breaker by preventing the charger from attempting to draw more current than is available
through the supply circuit breaker.
Example: when the breaker size parameter is set to 10 amps and AC loads are operating while the
charger is also charging the batteries, the Prosine automatically reduces charging current to help keep
the sum of all AC loads (including the charger) at or below 8 amps. As AC loads fluctuate, the Prosine
automatically adjusts charging current up to the maximum allowed by this setting.
For RV, marine, and mobile installations, the available shorepower circuit breaker size may vary
frequently. Marinas and RV parks often supply shorepower with from 15- to 50-amp service. By
adjusting the breaker size parameter in the AC Information menu, you can increase the maximum
current available for more rapid charging, or prevent nuisance circuit-breaker tripping when
shorepower current is limited.
To adjust the breaker size parameter, enter the AC Information menu by pressing the Enter key, as
shown below. Use the ▼ arrow key to scroll through the menu to the Breaker Size screen. Press
ENTER to enter the menu, followed by an arrow key to scroll to the desired value. Press ENTER
again to accept the value, then press ESCAPE to exit the menu.
