Float Transition Current Measurement Shunt

Solar Boost 6024H can use the internal current shunt measuring Output Charge Current, or an external
current shunt measuring net battery current to determine full charge. When the battery is unloaded during
charge or the load during charge is relatively constant, use the internal shunt. If load current is highly
variable, consider use of an external shunt for optimal charge control.
Solar Boost 6024H peut utiliser le shunt de courant intérieur qui mesure le Courant de Chargement de
Sortie, ou un shunt de courant extérieur qui mesure le courant net de la batterie pour déterminer la
charge complète. Lorsque la batterie est déchargée pendant le chargement ou la charge pendant le
chargement est relativement constante, utilisez le shunt intérieur. Si le courant de charge est très
variable, envisagez l'utilisation d'un shunt extérieur pour optimiser le contrôle du chargement.
Solar Boost 6024H kann den Innenstromschunt, der den Ausgangbeladungsstrom meßt, oder einen
Außenstromschunt, der den Nettobatteriestrom meßt verwenden, um die Vollbeladung festzustellen. Wenn
die Batterie während der Beladung ausgeladen ist oder die Beladung während des Vorgangs relativ
konstant ist, benutzen Sie den Innenschunt. Wenn Beladungsstrom hoch variabel ist, empfiehlt sich einen
Außenschunt für optimale Beladungskontrolle zu benutzen.
El Solar Boost 6024H puede usar el shunt interno de corriente, midiendo la corriente de carga de salida o
un shunt de corriente externo midiendo la corriente neta de la batería para determinar la carga completa.
Cuando la batería es descargada durante la carga, o la carga es relativamente constante, use el shunt
interno. Si la corriente de carga es altamente variable, considere la posibilidad de usar un shunt externo
para un control de carga óptimo.

If battery load current is highly variable during charge more effective charge control can be obtained through the use of an
external current shunt measuring net battery charge current. The wiring diagram of Figure 3 shows how this optional external
current shunt would be used. This external shunt can be an already existing shunt as long as it is in the negative leg of the
battery and is wired to measure net battery current. Note that each measuring device connecting to this shunt should have it's
sensing wires connected directly to the shunt sensing screw terminals. A variety of optional current shunts are available through
your Blue Sky Energy dealer.
The advantage an external shunt provides could be illustrated in the following manner. Suppose a battery is at a fairly high
state of charge in the acceptance mode, and is drawing 5 amps of charge current which is being provided by Solar Boost
6024H. If a 10 amp load is then placed on the battery, Solar Boost 6024H increases output current to hold the battery at the
desired acceptance voltage. Solar Boost 6024H is now delivering 15 amps, 5 amps to the battery as before, plus 10 amps to
the load. Using the internal shunt, it appears that the battery is now consuming 15 amps of charge current. But, the external
shunt still senses 5 amps of charge current since it is measuring net battery charge current. With the external shunt connected
to the Solar Boost 6024H charge control system, the charge control system measures only the 5 amps or charge current
producing optimal control of the charge process despite changes in battery load during charge.

Float Transition Current Setpoint

The Float Transition Current setpoint controls when the system switches between acceptance and
float. If charge current is less than the Float Transition Current setpoint during acceptance, the battery is
considered charged and system switches to float. If charge current is greater, the system switches to
acceptance. A lead-acid battery is considered fully charged when charge current during acceptance
decreases to ≈1 to 2 amp per 100 amp-hours of capacity. If load current is highly variable, consider use
of an external shunt for optimal charge control, or select a Float Transition Current setting that allows the
system to switch to float during light load and full charge conditions. Set the Float Current potentiometer
for a voltage on the "I Float" relative to "Com" test point per the following table based on the shunt used.
