Introduction
The Lithionics GTX12V630A-E2112-CS200 Victron kit is based on a
GTX12V630A-E2112-CS200 battery (630 amp hours) and a Victron MultiPlus
3000-watt inverter (a 2000-watt inverter/charger may be substituted without
any change in wiring). This combination is capable of providing enough power
to run your AC loads for extended periods of time. The inverter features true
sine wave grid quality power, adaptive charging, Power Assist, and many system
integration features.

Main Diagram
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. Suppose the positive cable supplying the inverter shorts to ground
internally. In that case, the chassis ground cable needs 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 the

MAIN DIAGRAM
Inverter Diagram
The inverter diagram depicts a typical AC installation. The main panel has an output breaker for the non-inverter loads. It is used to power high power loads that are beyond the capacity of the inverter such as a water heater or an electric stove. 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). The inverter has a power assist feature and when enabled can add up to 2kVA (2000 / 120 = 17A) to the output during periods of peak power requirement. Together with a maximum input current of 50A, this means that the output can supply up to 67A (50+17).
Inverter Diagram
An RCD (Residual Current Device) type circuit breaker rated to support the expected load must be included in series with the output, and cable cross- section must be sized accordingly. This breaker should be as close to the inverter as possible. If this breaker is not of the RCD (Residual Current Device) type, GFCI receptacles must be used at all AC outlets. The inverter is provided with a ground relay that automatically connects the neutral output to the chassis if no external AC supply is available. In an RV installation, the inverter chassis must be connected the vehicle chassis ground (via the negative distribution bus). The chassis grounding conductor must be 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. When using an inverter sub panel, the inverter neutrals must return to the inverter sub panel and not the main AC panel. A warning label should be installed at the main AC panel to indicate that there is an inverter in the system.
INVERTER DIAGRAM
Sterling Diagram
The Sterling Battery to Battery charger charges the house battery via the
vehicle’s alternator. This system uses either the Sterling BB1230 charger
(Mercedes recommendation), or the BB1260 charger depending on the size of the
alternator. The charger should be programmed to charge the battery using a
Lithium battery profile. The charger can also be configured to work with
vehicles using regenerative braking.
STERLING DIAGRAM
Solar Diagram
- 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.
SOLAR DIAGRAM
Battery/IonGage Diagram
The Advanced Series BMS includes an integrated SOC Gauge, designed to track the battery state of charge (percent of usable energy left in the battery) as well as other useful data parameters. Tracking the 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.

Parts List
Battery Installation
Check the battery for visible damage including cracks, dents, deformation and other visible abnormalities. The top surface of the battery and terminal connections should be clean, free of dirt and corrosion, and dry. Battery power should be turned off prior to the installation and for storage. Check the LED integrated into the Power button to make sure it is completely off. If the LED is on or blinking, press and hold the Power button for 3 seconds until LED turns off. Lithium batteries do not release gas during normal use. There are no specific ventilation requirements for battery installation, although enough airflow should be provided to prevent excessive heat build-up. The battery should be stored and installed in a clean, cool and dry place, keeping water, oil, and dirt away from the battery. If any of these materials can accumulate on the top surface of the battery, current leakage can occur, resulting in self-discharge and possible short circuits.
The battery is equipped with two flat threaded terminals designed for a 5/16”
or M8 size ring terminal lug and secured by included M8 bolts, flat washers
and lock washers. When using flat washers, it is critical to place the ring
terminal lug in direct contact with the top surface of the power terminal and
then place the washers on top of the lug.
Connect the positive and negative battery cables with correct polarity and
double check the polarity of battery circuit to avoid potential equipment and
battery damage.
DO NOT place any washers between the battery power terminal and the ring
terminal lug, as this could create a high resistance path and cause excessive
heating of the connection which could then lead to permanent battery damage or
fire. If you must attach more than one lug to each terminal, make sure at
least 1/4” or 6mm of thread is available to secure the connection.
Additionally, the ring terminal lugs need to be “clocked” in such a way that
they do not interfere with their flat conducting surfaces. Acquire and use
longer M8x1.25mm bolts if necessary. Tighten both M8 power terminal bolts to a
maximum of 108in- lbs/12.2Nm to ensure there is good contact with the ring
terminal lug. Over tightening terminal connections can cause terminal breakage
and loose connections can result in power terminal meltdown or fire.The
battery cables should be sized to handle the expected load. Refer to NEC Table
310.15(B)16 for the maximum amperage based on the cable gauge size. Cable
lengths in excess of 6 feet may require heavier gauge wire to avoid
unacceptable voltage drop. For more information refer to the National
Electrical Code for correct cable size, which can be located at www.nfpa.org
The battery circuit must be properly fused to handle the expected load and not
to exceed the battery specifications. After installation is complete, turn on
the battery power by a short-press of the Power button. The LED indicator
should come on to confirm the battery’s state.
- DO NOT connect multiple batteries in series to get higher voltage as it will damage the internal BMS.
- DO NOT attempt to disassemble the battery, as it could lead to permanent battery damage and voids your battery warranty!!!
