A reliable supply of 240V mains electricity is something many
of us take for granted, but for those in remote or isolated
locations, mains grid electricity may be unreliable, prohibitively
expensive to have connected, or may not be available at all.
In these situations, a DC to AC power inverter is the most
sensible solution to providing 240V mains power, and a Rich
Electric Combi Series interactive inverter-charger is the best
choice offering all the features, performance and flexibiliy
needed to give reliable 240V power in any number of different
off-grid or remote power systems.
Whether power be generated by renewable sources such as
solar, wind or hyrdo, or if it’s provided by a backup generator,
the Combi Series interactive inveters-chargers are more
than capable of managing and controlling power to ensure
stable power delivery with minimal fuss. Even in the harshest
of Australian outback conditions, or the bitter winter cold of
southern New Zealand, the Combi Series interactive inverterchargers will keep on delivering stable, reliable power.

Energy Sources
Live Remote with
Renewable Energy
• Live independently from the electricity grid
• Never have to pay a power bill
• Source green power from renewable sources
• Live remotely with all the comforts you need
When living remotely, either off the grid completely or in a
difficult or expensive location to obtain a grid connection,
there are a few choices for sources of power; connect
to the grid at potentially great expense (if it’s even
available), use a fossil fuel burning generator, or use
renewal energy sources.
The most sensible choice is to source power from
renewable sources, such as solar, wind or hydro power.
By using renewable energy sources, there is no reliance
on a stored supply of fossil fuels, the only reliance is
on the abundance of natural energy. Renewable energy
sources are collected, converted into electrical power,
and stored into a battery bank to be used when required.
By using renewable energy sources in a remote or off-grid
situations, the system can be completely independent
and not require any other external energy sources,
providing completely independent, green living.
Solar Power
Hydro Power
Wind Power
The Combi Series interactive inverter-chargers are a
fantastic solution for harvesting, storing and managing
renewable energy, with the ability to expand to integrate
with a solar array, hydro generator system, or wind
turbine generator. The Combi Series interactive inverterchargers are able to centrally manage and control
whatever renewable source is connected to the power
system to ensure optimal charge is delivered into the
battery bank, and that the stored power is then efficiently
converted back into usable 240V mains power.
Using renewable energy doesn’t mean losing life’s
creature comforts though! Thanks to the big power
capacity of the Rich Electric Combi Series interactive
inverter-chargers, comforts such as air-conditioning,
electric washing machines and other power hungry
appliances can still be used*, ensuring comfortable living
on a remote property.
* inverter size and renewable energy sources must be sized according to the load requirements.

By utilising low frequency inverter design, which employs a very large torroidal transformer with very high electrical
isolation, the Combi Series Interactive inverter-chargers are capable of handling the heavy start up surge load on
moderately sized domestic air-conditioner units, depending on what other 240V appliances are running at the time.
A 1500W unit can happily start and run a 2-3kW inverter type air conditioner, and a 3000W unit can happily start and
run a 5-6kW inverter type air conditioner.
The high current 4-stage battery charger ensures that maximum
charge is delivered into the batteries whilst the backup generator is
running, reducing the necessary run time of the generator.

In many applications, 1500W or 3000W is
simply not enough power to support the
240V loads – or to make matters more
complicated, 3-phase power is required.
3000W
With the Combi Series Interactive inverterchargers, multiple units can be parallel
stacked, or multi-phase stacked, to achieve
bigger output power and provide 2-phase or
3-phase power.
3 Units In 1
Packed inside the Combi Series Interactive
inverter-chargers are three main core elements:
a powerful low frequency pure sinewave
inverter, a high power 4-stage battery charger,
and a fast action automatic AC changeover
switch. By having all three units combined into
the one product saves on space, weight, and
reduces installation complexities.

Generator Auto Start
In an off-grid application, existing AC power sources typically only
have a limited capacity, for example a generator could be the only
existing source of AC power. By using a Combi Series interactive
inverter-charger you can avoid any problems this could cause.
When paired with a generator with compatible
auto-start functionality, a Combi Series
Interactive inverter-charger can start the
generator automatically. You can program the
generator to start when batteries discharge to
a certain level, the AC load exceeds a certain
level, at certain times of day, or programming
generator run block-out times*, allowing for
better system integration and automation. In
addition, minimum run times and minimum off
times are individually programmable as well.
Simply program the Combi Series Interactive inverter-charger with
the maximum power available from the generator or other AC power
source, and the Combi will not exceed that power limit. When more
power is required than what the generator/other AC source can
provide, the Combi will boost the output power by adding extra
inverter power taken from the batteries. When the load decreases,
any spare AC input power is used to recharge the batteries. This can
eliminate the need to select a generator capable of supplying the peak
power demands, as the Combi Series Interactive inverter-charger can
handle the peak; so a smaller sized generator can be used at a greater
operating efficiency, using less fuel.

Features
Dynamic Power Shifting
As well as being able to boost the output
power, the CombiPlus and SuperCombi
have another special feature that allows
you to run a much smaller generator than
would otherwise be needed. Dynamic Power
Shifting is a feature for heavy startup loads
such as an air-con unit, which places the
heavy startup load on the inverter, and then
once the load has stabilised the Combi slowly
transfers the load across to the generator. So
now, instead of needing a big 3kVA or larger
generator to kick over the air-con unit, it is
possible to use a far smaller unit, running at a
greater efficiency burning less fuel.
Centralised System Control
(Expansion Products)
Temperature Rating and De-Rating
The power output of a Combi Series Interactive
Inverter-Charger has NO DE-RATING.
Combi Series interactive inverter-chargers are
rated at 70ºC, meaning that they are guaranteed
to provide their full rated power output right up
to 70ºC (thermal shutdown at 71ºC). This means
more power in normal operative conditions than
alternative inverters rated at 25ºC!
Power Output
Most inverters on the market are rated at an internal ambient temperature of 25ºC,
and due to a phenomenon known as “de-rating” their output power reduces as
the operating temperature increases. This
temperature is the ambient temperature inside
100%
the inverter, which is often 10-15ºC higher than
the surrounding environment, meaning that an
inverter operating on a typically warm 30ºC day
80%
will actually be running at 40-45ºC inside the case.
This would typically only provide around 70% of
60%
full rated output.
Optional Rich Electric products can be
incorporated into the system and centrally
controlled and monitored through the Combi
Series Interactive inverter-charger. Allows
for full system control and monitoring of all
parts through the one central device.

Combi Series
Applications
Off-Grid Solar System
In most off-grid applications, solar power will be harnessed as DC power and stored into a battery bank to support
the power demands. Since solar is not always able to supply all the power demands, a generator is almost always
incorporated to supplement the energy provided by solar and to provide backup power.
A typical Combi Series off-grid solar system would be something like this:

Hybrid Off-Grid Solar System
For larger systems, or where the majority of daytime loads are using AC power, it is often more efficient to directly
convert solar power into AC, using the Rich Electric Solarworx Grid Inverter. The Solarworx grid inverter supplies AC
power to the 240V loads, and the excess is used to recharge the batteries. When the load exceeds the power delivered
by the Solarworx, the Combi Series Interactive inverter-charger uses the Power Support feature to boost the total
power output. When the batteries become fully charged, the Combi Series will then tell the Solarworx to shutdown via
the Combi-Net communication cable.
In some other applications, grid power may already be available to some extent. This grid power may be unstable,
unreliable, or perhaps the intention of the hybrid system is to minimise use of grid supplied power to be as selfsufficient as possible or to maximise solar feed-in tariff to the grid; whatever the application, a Combi Series
interactive inverter-charger and Solarworx grid inverter can be combined to supply power as required. Furthermore,
since the system is utilising the Solarworx grid inverter, excess power can be put back into the grid, and a “feed-in”
tarrif paid to the household*.
These Hybrid Grid-Connected Solar Systems systems can be configured to:
• Minimise reliance on grid power
• Minimise or eliminate use of grid power
• Provide backup protection where grid power is unreliable
• Maximise the amount of solar power fed back into the grid
• Take maximum advantage of time-of-use metering
The Solarworx grid inverter does need a “grid” supply to synchronise to, which is provided by the Combi Series
inverter output. This system can also be very handy in applications where the solar panels need to be installed quite
some distance from the batteries, for example in a remote home where the solar panels need to be installed on the
roof of the home, and the batteries and Combi Series Interactive inverter-charger are installed in the shed over 50m
away. In these applications, converting the solar directly to AC power eliminates the need to run excessively large DC
cabling a long distance from the solar panels to the batteries.

When the advanced features such as DC
charging control, AC charger timer, remote
generator timer, and DC load control are not
required, the CombiPlus is the best choice.
The CombiPlus still has all the power support
features, remote generator start, temperature
rating and power output that is expected with
an Invertek Combi Series inverter-charger.
Carrying all the features, bells and whilstles you
would expect from the flagship of the Invertek
Combi Series. Carries all the features of the
CombiPlus, but also has ability to auto-start/
run the generator on a timer, run the battery
charger on a timer, control DC charging
sources, as well as control DC load outputs.
A multi-purpose grid-inverter capable of working either directly
from solar panel input, or from a battery input that is charged by
renewable sources - making it suitable for solar, as well as wind
and hydro renewable energy. When matched with a Combi Series
interactive inverter-charger, the Solarworx grid-inverter allows for
hybrid system functionality.
SunStar Solar Charge Controller 45A/60A
True commercial grade PWM (pulse width modulated) solar charge
controllers, rated at either 45A or 60A. Multiple units can also be
"stacked" up to a maximum of 10 units for extra capacity. Can be linked
to the Combi Series models via the CombiNet system for centralised
control and monitoring through the Combi inverter-charger. SunStar
controllers can also be configured as a diversion load controller, which
is particularly handy for use with wind turbine generators.
SunStar MPPT Solar Charge Controller 50A
High grade maximum power point tracking (MPPT) solar charge
controller for maximum battery charging efficiency, providing over 96%
efficiency. Multiple units can be stacked for increased capacity up to a
maximum of 16 units. With MPPT conversion technology, the solar panel
array can have a nominal voltage higher than the battery charge voltage,
reducing the size of DC cabling required on the solar array. Also
features programmable relays outputs and a multitude of other features.
Invertek DC-DC Isolator - 140A
A fully programmable, bi-directional voltage sensitive relay that can be
used in multiple applications. Can be used for dual battery charging
and isolation, or as a controller for a DC charging source or as a DC
load controller with low voltage disconnect/reconnect. The DC-DC
isolator can be used independently, or can be combined with the
SuperCombi to provide centralised control and monitoring of DC
charging and DC loads. Not compatible with CombiPlus.

Invertek ATS - 20A
A fully automatic AC transfer switch, which automatically selects
between a master and a slave AC power source. When used
independently, it can be used to automatically change between mains
and generator power, mains and inverter, or inverter and generator
power. When linked to a Combi Series interactive inverter-charger via
the CombiNet link, the ATS can change the Combi's operating mode
between Mode 1 and Mode2, to instruct the Combi whether the AC
input is coming from a generator, or from mains grid power.

In most installations, the Combi inverter and battery bank will be
installed in a shed, garage, or other location outside the main home/
building, where it is inconvenient to view the current status of the
power system. By using the remote control panel, a complete replica
of the front panel of the SuperCombi or CombiPlus can be installed in
a more convenient location inside the property, giving full control and
monitoring without having to venture out to wherever the Combi unit
is installed.

An absolute must for any installation, and cheap insurance against
damage to the very expensive battery bank. Installing the battery temp
sensor tells the Combi what temperature the battery is operating at, so
that the Combi can adjust charging voltage and current accordingly, to
avoid permanent damage to the batteries. Batteries do get hot under
heave loads, so it is important to adjust charging accordingly.
