Whether hooked to shore power or operating
from the generator, the internal battery charger of
the inverter will automatically charge the batteries
when AC power is supplied to the input terminals of
the inverter. The time it takes to charge the batteries
to a full state of charge varies greatly. It can take
several hours or even days depending on the inverter
set-up parameters and actual state of charge of the
batteries. The inverter uses a three stage charging
cycle. The first stage is “bulk” charge. The bulk
charge will bring the DC voltage up high, initially
between 14.2-14.6 Volts, actual bulk charge voltage depends on which bat-
tery type has been selected in the programming menu. The bulk charge cycle
is controlled by voltage and current. The length of time the inverter is in the
bulk charge cycle will vary with the state of charge of the batteries. The sec-
ond stage is the “absorb” cycle. The battery voltage in the absorb cycle is the
same as the bulk charge cycle between 14.2-14.6 Volts. The length of the
absorb cycle is a timed event determined by the inverter. The final charging
stage is the “float” charge cycle. Approximately 80% of the charging cycle
has been completed by this time. The float charge voltage is generally around
13.3-13.7 Volts. The last 20% of the charge cycle typically takes the most
amount of time.
NOTE: The inverter will charge the batteries with AC power applied
regardless of remote status.
The inverter uses a battery temperature sensor to adjust charge voltage.
When the battery temperature rises the BTS will send this information, regis-
tering as counts, to the inverter to decrease charge voltage. Voltage compen-
sation with temperature variation is necessary to keep charge voltage at opti-
mum figures. The BTS should be adhered to a house battery. If the BTS is
unplugged, the inverter default setting of 77º F/25º C is used as the charge
temperature reference point.
Incorporated in the inverter is a double pole “pass-through” relay which
trips when AC power is supplied to the input terminals. This will transfer AC
power through the inverter to a sub panel supplying AC power to outlets and
appliances. When AC power is supplied to the inverter, the internal battery
charger will “ramp up” battery charging voltage. A 20 second time delay
allows charge stabilization before pass through AC power is supplied to the
sub panel.
