Stacking For More Power/Multi-Phase

simply not enough power to support the 240V loads – or to make matters more

With the Combi Series Interactive inverter-chargers, multiple units can be parallel stacked, or multi-phase stacked, to achieve bigger output power and provide 2-phase or

3 Units In 1

inverter-chargers are three main core elements:

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.

All features are seamlessly integrated to give fully automatic operation without any manual

Generator Auto Start

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.

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.

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.

Power Support

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.

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

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.

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:

Applications

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

power output. When the batteries become fully charged, the Combi Series will then tell the Solarworx to shutdown via the Combi-Net communication cable.

The Solarworx grid inverter does need a “grid” supply to synchronise to, which is provided by the Combi Series

some distance from the batteries, for example in a remote home where the solar panels need to be installed on the

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.

Hybrid Grid-Connected Solar System

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 self-sufficient as possible or to maximise solar feed-in tariff to the grid; whatever the application, a Combi Series

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*.

Battery Temperature Sensor

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.
