ELECTRICAL
The built-in Charge Wizard is a microprocessor-controlled system that constantly
monitors the battery voltage and ensures rapid; yet, safe, recharge. The Charge Wizard
can select one of three charging voltages and one of four operating modes depending on
the condition and use of the battery.
BOOST MODE: If the voltage drops below a preset level the output voltage is increased to
approximately 14.4 VDC to rapidly recharge the battery.
NORMAL MODE: Output voltage is set at approximately 13.6 VDC
STORAGE MODE: If there is no significant battery usage for 30 hours the output voltage
reduces to 13.2 VDC for minimal water usage. In storage mode, the output voltage
increases to 14.4 VDC for approximately 15 minutes every 21 hours to help prevent sulfation
of the battery plates.
INVERTER/CHARGER
(OPTIONAL EQUIPMENT)
USED WITH AGM AND LITHIUM BATTERY PACKAGES ONLY
For operating instructions and troubleshooting, view the manufacturer’s manual.
The optional inverter/charger is a combination of an inverter, battery charger and transfer
switch into one complete system. When AC power is available, the inverter/charger
recharges the batteries. It also allows surplus AC power to pass through and power
downstream AC loads, such as a television, microwave, or air conditioner. When AC power
is disconnected, the unit can invert DC battery power into AC electricity.
The inverter/charger will charge batteries in a sequence known as three-stage charging.
The charging voltage delivered to the battery depends on the battery’s type, temperature
& state of charge. The three automatic charge stages are Boost, Absorption & Float.
Bulk Stage: the first stage in the charging process provides the batteries with a
controlled, constant current. Once the battery voltage rises to the absorption voltage
threshold, the charger switches to the absorption stage.
Absorption Stage: during the absorption stage, the inverter/charger begins operating in
a constant voltage mode and the current falls gradually as the amp hours are returned to
the battery.
Float Stage: maintains the batteries slightly above shelf discharge voltage. The charger
automatically switches to the float stage after the batteries have received a bulk and
absorption charge.
