Solar Input on the BP35-PM
Connection of solar panels to the
BP35-PM
must always be through an external
regulator. The external regulator may either be a Maximum Power Point Tracker
(MPPT) regulator or Pulse Width Modulator controller.
Always consult with manufacturer’s specifications before choosing an external
regulator to fit between your solar panels and the
BP35-PM
, ensuring that:
1. The solar regulator output does not exceed 30A, and
2. The charging profile of the solar regulator is suitable for the battery in use
Solar Input on the BP35-HA and the BP5-SR
The
BP35-HA
and the
BP35-SR
both feature an in-built MPPT charger. This
enables solar panels to be connected directly to the
BP35-HA
or
BP35-SR
without
the need for an external regulator.
The MPPT charger supports the use of standard 12V solar panels up to a total of
450W.
DO NOT connect solar panels directly to the
BP35-PM
solar input terminals.
BATTERY CHARGING AND MANAGEMENT WITH THE BATTERYPLUS35
The
BatteryPlus35
can deliver up to 35A to simultaneously power loads and
charge the caravan battery, with a maximum charging current of 20A for the
BP35-PM
and
BP35-SR
and 30A for the
BP35-HA
.
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 off non-
essential loads.
Auxiliary Charging
When charging from auxiliary, the
BatteryPlus35
monitors the battery voltage
level and charges as needed. Auxiliary charging is enabled only when the auxiliary
voltage exceeds the battery voltage by at least 0.5V.
Mains Charging
When charging the battery from mains, the
BatteryPlus35
applies a multi-stage
charging algorithm. Further details can be found in the Appendices.
Solar Charging with the BP35-PM
Battery charging depends on the solar regulator used to connect the solar panels
to the
BP35-PM
.
