Troubleshooting

Unexplained Faults

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

current	Small battery bank size. To avoid damaging the batteries the PROsine
	will generally charge in the FLOAT or ABSORPTION stages at only 25-
	30% (in Amps) of the configured battery bank capacity (in A-hr) - this
	varies with the battery type configured in the PROsine.
	Battery does not accept full current due to being partially charged or
	damaged.
	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.
