The main diagram depicts the general layout of the system. The 2/0 AWG battery positive cable is connected to the
main positive distribution bus via a 300A post-mounted fuse and an isolation switch.
The inverter is connected to the positive distribution bus via a 250A class T fuse and an isolation switch. The class T
fuse block should be mounted as close as possible to the positive distribution bus. The inverter switch is required for
inverter isolation and inrush management when first turning on the system. The chassis DC grounding cable (green)
should be sized not less than one size smaller than the DC positive conductor and have a capacity such that the DC
positive fuse has an amperage rating not greater than 135% of the current rating of this ground wire.
If the positive cable supplying the inverter shorts to ground internally, then the chassis ground cable needs to be able
to carry enough current to blow the inverter fuse without melting and possibly causing a fire.

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
page, FAQ Section at this link https://lithionicsbattery.com/support/

A warning label should be installed at the main AC panel to indicate that there is an inverter in the system.
The inverter diagram depicts the Victron Multiplus II configured with a 120/240
VAC split/phase shore power input. The MultiPlus II can also be configured for
single/phase 120VAC input. When an AC source is available, the MultiPlus II will
feed through the AC to its output. The output will therefore mirror the AC input.
When the MultiPlus II is in inverter mode the output is 120V single phase only. In
inverter mode, the MultiPlus II connects both output lines (L1 and L2) together to
provide 120VAC to loads on either line.
Any 240V loads will only be supplied when the MultiPlus II is supplied by a splitphase
AC source. This prevents heavy loads such as water heaters or 240V air conditioners
from discharging the battery.
The AC input must be protected by a magnetic circuit breaker rated at 50A or less,
and the cable cross-section must be sized accordingly. Make all connections using
proper crimp-on connectors (do not use twist on connectors).

LITHIONICS BATTERY, CLEARWATER, FL 33765 USA | PH: 727.726.4204 | FAX: [phone] | WEB: LITHIONICSBATTERY.com 8
The MultiPlus II has two AC outputs AC-1 and AC-2.
AC-1
The MultiPlus II provides power to the AC-1 output (120V only) when the shore power is disconnected. With its
PowerAssist feature the MultiPlus II can add up to 3kVA to the AC-1 output during periods of peak power requirement.
Together with a maximum input current of 50A this means that the output can supply up to 75 A. An earth leakage circuit
breaker rated to support the expected load must be included in series with the output, and cable cross-section must be
sized accordingly. The maximum rating of the circuit breaker is 75A.
AC-2
The auxiliary (AC-2) output is live only when AC is available on the input of the MultiPlus II. Heavy loads that would
discharge the battery can be connected to this output. The maximum rating of the circuit breaker is 35A.
The inverter is provided with a ground relay that automatically connects the neutral output to the chassis ground if no
external AC supply is available. In an RV installation, the inverter chassis must be connected to the vehicle chassis
ground (via the negative distribution bus). The chassis grounding conductor must be sized not less than one size smaller
than the DC positive conductor and have a capacity such that the DC positive fuse has an amperage rating not greater
than 135% of the current rating of this grounding wire.
For a graphical view of the power flow please see the power flow diagrams included in this manual.

The Victron Smart Solar MPPT solar charge controller uses maximum power point
tracking that optimizes the match between the solar array and the battery bank. It
converts the higher voltage DC output from the solar panels down to the lower
voltage needed to charge the batteries. The PV solar array is connected to the MPPT
charger with a circuit breaker (not supplied). 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 charger is connected to the positive distribution bus via a 40A fuse. The fuse
and wire sizes are based on the Victron MPPT 100/30 charge controller, if a larger
controller is used then the fuse and wire sizes should be increased as required.
Using the VictronConnect App on your smartphone you can connect via blue tooth
and remotely control and monitor the Smart Solar MPPT charger.

The Advanced Series BMS includes an integrated SOC Gauge, designed to track battery state of charge (percent of
usable energy left in the battery) as well as other useful data parameters. Tracking state of charge is accomplished by a
Coulomb counter, based on an internal, high sensitivity hall-effect sensor. The SOC Gauge data will only be correct if the
configuration parameters are set correctly, which are pre-set initially by Lithionics Battery, but are user adjustable with
supporting hardware. The SOC Gauge will also track and display live amperage (A), live wattage (W), battery voltage (V),
temperature (F/C), amp hours (Ah), watt hours (Wh), time remaining (d/h), etc. The meter will be most accurate if the
battery is fully charged on a regular basis. If the battery is always partially charged, then the SOC meter reading may drift
in the long term and will become less accurate. When the most accurate measurements are required it is recommended
to perform a full charge at least weekly.
