Inverter three-stage charging cycle:
• Bulk Charge Cycle: Brings the DC voltage
up high, initially between 14.2 - 14.6 Volts.
The length of time the inverter is in Bulk
Charge depends the state of charge of the
batteries.
• Absorb Cycle: Absorb Cycle battery volt-
age is the same as the Bulk Charge Cycle,
between 14.2 - 14.6 Volts. Length of the
Absorb Cycle is a timed event determined
by the inverter.
• Float Charge Cycle: Charge voltage is gen-
erally around 13.3 - 13.7 Volts.
Approximately 80% of the charging cycle
has been completed by this time.
NOTE:
The Inverter/Charger will charge the
batteries with AC power applied
regardless of remote status.
Battery Temperature Sensor
A Battery Temperature Sensor (BTS) is affixed to one of the house bat-
teries to measure battery temperature and send that information to the
inverter. When battery temperature rises, the inverter will decrease charge
voltage to prevent boiling the batteries. When battery temperature cools, the
inverter will raise charge voltage. Voltage compensation with temperature vari-
ation is necessary to keep charge voltage at optimum values. If the BTS cord
is unplugged from the inverter, the inverter will use a temperature default
setting of 77º F/25º C as a reference point.
Pass-Through AC Power
A double pole "pass-through" relay trips when AC power is supplied to the input terminals to transfer
AC power through the inverter to the sub breaker panel in the bedroom. The sub breaker panel supplies
AC power to most outlets and appliances. When the inverter receives AC power, the internal battery
charger "ramps up" battery charging voltage. After approximately 20 seconds, the relay engages, allowing
AC power to pass through the inverter to the sub-panel.
