BATTERY CHARGING AND MANAGEMENT
The BatteryPlus35-II can deliver up to 35A to simultaneously power loads and charge
the caravan battery, with a maximum charging current of 20A for the BatteryPlus35-
II-SI and BatteryPlus35-II-SR and 30A for the BatteryPlus35-II-HA with the
di
ff
erence being reserved to supply 12V loads.
The maximum charging current will be reduced if the loads present are drawing
significant current and as the battery approaches full charge. To ensure that the
caravan battery is charged by the maximum charging current, switch o
ff
non-
essential loads.
Auxiliary Charging
When charging from auxiliary, the BatteryPlus35-II monitors the battery voltage
level and charges as needed. Auxiliary charging is commenced only when the
auxiliary voltage exceeds the battery voltage by at least 0.5V and is greater than
12.6V.
Mains Charging
When charging the battery from mains, the BatteryPlus35-II applies a multi-stage
charging algorithm. Further details can be found in the
Appendices
.
Solar Charging with the BatteryPlus35-II-SI
When charging the battery from solar, the
BatteryPlus35-II-SI
applies a multi-stage
charging algorithm.
The BatteryPlus35-II-SI will use solar as a charging source if the voltage generated
by the solar panel is greater than the battery voltage.
Solar Charging with the BatteryPlus35-II-HA and BatteryPlus35-II-SR
When charging the battery from solar, the
BatteryPlus35-II-HA
and
BatteryPlus35-
II-SR
applies a multi-stage charging algorithm.
The BatteryPlus35-II-HA and BatteryPlus35-II-SR MPPT regulator is designed to cap
the solar output to 30A. This allows you to utilise 450W or greater on the roof of your
caravan, which will allow you to fully maximise the potential of the MPPT regulator.
The BatteryPlus35-II-HA and BatteryPlus35-II-SR will use solar as a charging source
if the voltage generated by the solar panel is greater than 17.5V for at least two
minutes.
WARNING
Do not attempt to charge non-rechargeable batteries. Charging a non-rechargeable
battery may result in the battery catching fire or a possible explosion.
