Why We Built a Separate Version for South America: 110V Single-Phase vs 7.2kW Split-Phase

South America is our next growth market, and it needed its own machine. What 110V single-phase and split-phase 110/220V actually mean for your load, why 7.68kWh and 16kWh pair with different systems, and why the green housing and touchscreen are preference, not performance.

Since February 2025, customers have been coming to us asking for machines for the South American market. We've confirmed South America as our next growth region and built a dedicated version. Here's why it was worth doing separately — not because a new housing looks better, but because **the grid configuration is different, and copying our standard machine would cause real problems**.

The Grid First: 110V, and More Than One Kind of 110V

Most of our exports are European-spec machines, built around 220V mains. Much of South America runs on **110V**, and that difference is not "a bit lower voltage" — it changes the whole electrical logic.

More importantly, many South American countries do not use simple 110V single-phase. They use a **split-phase structure where two 110V legs combine into 220V**. One 110V leg serves ordinary sockets; the two combined serve high-power appliances. This structure is common in North America too, which is why the North American split-phase approach transfers directly, while the European 220V approach does not fit.

That is the reason for a dedicated version: **wrong voltage configuration means the unit cannot drive local appliances, and wrong wiring means local installers will not know how to connect it.**

Two Models: 3.6kW Single-Phase and 7.2kW Split-Phase

We built two models for South America, covering two different needs.

Model 1: 3.6kW single-phase 110V

3.6 kilowatts output at 110V single-phase. Battery configurable at 7.68kWh or 8kWh.

This specification maps to **ordinary household use**: lighting, TV, fridge, water pump, small appliances. The 110V single-phase output drives these directly, and 7 to 8kWh covers a day of basic load. If your local grid is single-phase 110V with no split phase, or you only need to run basics, this model is enough.

Model 2: 7.2kW split-phase 110/220V

7.2 kilowatts with split-phase output — **both 110V and 220V available**. Paired with 16kWh of battery.

This model solves the "one system with both high-power appliances and small loads" problem. The 220V leg carries air conditioners, motors and power tools; the 110V leg carries lights, TV and chargers. Each leg does its own job, no compromise. 7.2kW with 16kWh is enough to carry a whole house, or a small workshop or shop from day into evening.

**How to choose**: first check what structure your local grid uses, then check whether your loads include 220V high-power appliances. If both matter, go split-phase.

Two Non-Technical Changes: Green and Touchscreen

Customers ask about these two constantly, so let me be clear.

**The housing is green.** The standard colour for the South America market is green. This is not a technical requirement, it is market preference — green has better local acceptance and stands out outdoors. What actually affects performance is the voltage configuration and the battery capacity, not the colour.

**The split-phase unit gets a touchscreen.** The split-phase model carries more power and more functions, and needs to display two voltage legs, charge and discharge status. Rotary switches are not enough. A touchscreen shows everything and is simpler to operate. This is an experience upgrade, not a performance upgrade.

Keep these two separate from the voltage question — what you should scrutinize is whether the voltage is right and whether the capacity is enough, not what colour the housing is or whether the screen is touch-capable.

Euro Terminals and No-Install: Practical Advantages in South America

The interfaces keep Euro-style terminals, with "foolproof" input and output wiring. For South American customers this is an advantage — the terminals are standard parts, local electricians have seen them before, so wiring is guesswork-free and spares are easy to source.

The install philosophy stays no-install: unbox and use, without a professional team on site. In many parts of South America, construction and after-sales resources are not as dense as in Europe or North America, so a machine the customer can set up themselves is more practical than a few extra features.

Bottom line: the South America version is not "the same machine in a new colour" — it is **a voltage solution rebuilt around the local grid**. Single-phase 110V with 7 to 8kWh for daily use; split-phase 110/220V with 16kWh for whole-home with heavy loads. If you're interested in the South America market, let's talk in the comments.

FAQ

• Why build a separate all-in-one version for South America?
  Grid configuration. Much of South America runs on 110V, and several countries combine two 110V legs into a 220V split-phase supply. A standard 220V European unit cannot drive local appliances correctly and the wiring is wrong, so a dedicated version is needed.
• Single-phase 110V or split-phase 110/220V?
  The 3.6kW single-phase 110V unit suits small systems running ordinary appliances, paired with 7.68 to 8kWh. The 7.2kW split-phase model outputs both 110V and 220V — big loads like air conditioners and motors on the 220V leg, small appliances on 110V — suited to whole-home or light commercial use with 16kWh.
• Why the green housing and touchscreen on the South America models?
  Both are market preference rather than technical necessity. Green has better local acceptance and recognition; the split-phase unit carries more power and functions, so a touchscreen is easier to operate than rotary switches. What actually affects performance is voltage configuration and battery capacity.
