The inverter is controlled by the
Digital Multi Control
Panel. The front mounted switch is used to turn the system on, off or to charger only
operation. The shore current limit is set by the control knob. Turning the knob to the right or left sets the desired value. The current limit is shown
on the 7-segment display.
The
Lithionics IonGage
monitors battery voltage, current, power, amp-hours consumed and state of charge.
The
Victron Smart Solar
MPPT charger is connected to the positive distribution bus via a 40A Maxi fuse. The PV solar array is connected to
the MPPT charger via a circuit breaker. The specified circuit breaker is only rated at 48VDC; if your PV solar array has an open circuit voltage
that is higher, then another circuit breaker with a higher voltage rating must be substituted. The fuse and wire sizes are based on the
Victron
Smart Solar
MPPT 100/30 charge controller, if a larger controller is used then the fuse and wire sizes should be increased as required.
The
Sterling Battery to Battery
charger is connected to the positive distribution bus via a 50A Maxi fuse (80A for the Sterling BB1260 charger).
It also has a fuse at the starter battery, this fuse must be installed as close to the battery as possible.
Wiring note:
A total DC power circuit resistance between a single Lithionics battery and a 3000W inverter can be as low as 5 mOhm (0.005 Ohm), when
using short wires to connect the battery to the inverter. With a typical battery voltage of 13.5V, this can result in an inrush peak current of 2,700
Amps (!!!) from the battery to the inverter capacitors. This surge only lasts around 1 millisecond but could be enough to damage the Battery
Management System (BMS) or even damage the inverter. The minimum required wire size and length stated in the wiring diagram are provided
to ensure minimum circuit resistance of at least 5.6 mOhm to reduce the inrush under 2,400A. For more information refer to Lithionics Support
