BATTERY CHARGING AND MANAGEMENT WITH THE J35
Input Power Sources
The J35 may be powered from mains, AUX or solar inputs to provide battery
charging current and power to caravan loads.
If mains and one or more other sources are available to the J35, the J35 will be
powered exclusively by the mains source.
If both AUX and solar inputs are available and the mains is not, the J35 will draw
power from both the AUX and solar inputs. As full charge approaches, one of
these sources may dominate the other as appropriate.
Battery Charging
The J35 can simultaneously deliver up to 20A (J35A) or 35A (J35B-L, J35D) to
the caravan battery and loads from the mains input source, with a maximum
charging current of 15A (J35A) or 30A (J35B-L, J35D).
The maximum charging current will be reduced if loads 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.
When charging the battery from mains, the J35 applies a multi-stage charging
process.
For charging from AUX and/or solar sources, the J35 monitors the battery
voltage level and charges as needed.
Battery Health Preservation
The J35 preserves battery health by preventing the battery from excessive
discharge. The J35 will start a two-stage shutdown or Low Voltage Disconnect
(LVD), powering down all J35 outputs. This is to conserve remaining battery
capacity until the battery can be charged.
