Solar Charging with the BP35-HA and BP35-SR
When charging the battery from solar, the
BP35-HA
and
BP35-SR
applies a multi-
stage charging algorithm.
The
BatteryPlus35 (HA and SR)
will use solar as a charging source is the voltage
generated by the solar panel is greater than 17.5V for at least two minutes.
Battery Health Preservation
The
BatteryPlus35
preserves battery health by preventing the battery from
excessive discharge. The
BatteryPlus35
will start a two-stage shutdown or Low
Voltage Disconnect (LVD), powering down the
BatteryPlus35
outputs. This is to
conserve remaining battery capacity until the battery can be charged.

LVD Mode voltage thresholds
The
BatteryPlus35
will enter the two stages of LVD, ECO Mode and Storage Mode,
when the caravan’s battery voltage falls below the LVD thresholds.
ECO MODE
The
BatteryPlus35
will provide power to the CAN bus. This allows you to continue
to monitor battery consumption from your battery monitor. However, power to the
load terminal block will be turned off (except for terminal 1) and you will not be
able to use your battery monitor to power caravan loads.
To exit ECO Mode, start battery charging. The
BatteryPlus35
will exit ECO Mode
when the battery charges to the Recovery voltage. Upon exit of ECO Mode, the
BatteryPlus35
will automatically return to its previous state of operation.
When in ECO Mode you may temporarily turn on caravan loads for a short time by
cycling the switch connected the
BatteryPlus35’s
RSW input. This feature allows
you to retract slide-outs or electric steps should you need to pack your caravan.
If a battery monitor is connected, this may also be done by pressing the Battery
button.
