Troubleshooting
Unexplained Faults
Sometimes the PROsine may not show a fault at the panel, but may be acting in an unexplained way.

| Other AC loads are present on the PROsine output and the unit is reducing |
| the charging current so that the total AC input is kept below 80% of the |
| AC Breaker Size setting (per UL and CSA requirements). Or the AC |
| Breaker Size has been configured to a low value to limit the charging |
| current so the PROsine can charge batteries from a weak AC source. With |
| no additional AC output loads this breaker setting must be 19A or greater |
| so that the PROsine can draw 15Aac to provide 100A of battery current. |
| The PROsine internal temperature is high. To avoid overheating the |
| PROsine will reduce the allowable charging current if one of the internal |
| temperatures exceeds 75°C. |
