Setting the Power Share amps can limit the amount of AC power
available to the internal charger. Battery charger draw can exceed 20 AC
Amps. When hooked to anything less than 50 Amp service it may be
necessary, depending on other AC loads, to adjust the Power Share amps to
avoid overloading the shore power breaker.
NOTE: Limiting the amount of useable current for the charger
increases the amount of time necessary to charge the batteries.
The time it takes to fully charge the batteries varies greatly. It can take
several hours or even days, depending on the inverter's settings and state of
charge of the batteries. The charge cycle is done in three steps:
• First step is "BULK" charge.
The "bulk" charge will bring the DC voltage up high, initially
between 14.2 - 14.5 Volts DC, depending on conditions. The
length of the bulk charge cycle depends on the condition of the
battery, loads and other factors. When the battery voltage attains
14.2 - 14.5 Volts DC, the charger begins the next cycle.
• Second step is the "ACCEPT" cycle.
The voltage in this cycle is the same as the bulk charge cycle
14.2 -14.5 Volts DC. The length of the absorb cycle will vary
with state of charge of the batteries.
• Final step is the "FLOAT" charge cycle.
Approximately 80% of the charging has been completed at this
time. The float charge voltage is generally around 13.3 - 13.7
Volts DC. The last 20% of the charge cycle of the batteries
typically takes the most amount of time. The charging cycle is
initiated each time the inverter is disconnected or reconnected
to AC power. Repeated charging cycles in succession can lead
to boiling of the batteries.
Incorporated in the inverter is a double pole "pass-through" relay that
trips when AC power is supplied to the input terminals. This relay transfers
AC power through the inverter to the two circuit breakers located on the
front of the inverter. The two breakers supply AC power to various outlets
and the microwave. When AC power is supplied to the inverter, the internal
battery charger will "ramp up" battery charge voltage. A 20 second time
delay allows charge stabilization before pass through AC power is supplied
to the breakers.
