Can you imagine being able to switch from mains power to your backup power system without even the blink of an eye? That's how fast Sigenergy's HomeMax Gateway is, a device designed to switch the power supply in 0 ms, i.e. practically instantaneously. This is vital for installations where power outages result in production losses, or even safety risks.

The HomeMax Gateway is a device that sits between the electrical distribution network and your power generation (or storage) system. Its main function is to take control of the power supply in the event of voltage drops, fluctuations or outages, ensuring that your installation continues to operate without noticeable interruptions.

• 0 ms switching capability: Switching to the backup source is instantaneous.

• Wide range of power ratings: Available in single-phase 24 kW and three-phase versions of 50 kW, 120 kW, 180 kW, 300 kW, 600 kW and 1200 kW.

• Robust design: Intended for high consumption residential environments, as well as industrial and commercial uses where reliability is key.

In most backup systems, even if the switching time is very low (e.g. a few milliseconds), a small ‘cut-off’ is always noticeable. This outage, however small it may be, can generate:

1. Production stoppages: In automated manufacturing lines, even a brief interruption can force process restarts, recalibrate machines or scrap part of the production.
2. Safety risks: Some sensitive medical or process equipment cannot be stopped for a moment without putting people and production at risk.
3. Data loss: Critical computer systems, such as servers or control equipment, can lose data when power is lost, even if only for an instant.

With the Gateway HomeMax, these problems are completely eliminated, as the changeover is so fast that it does not cause voltage drop or affect the operation of the machinery.

The HomeMax Gateway integrates advanced power electronics and an ultra-fast mains sensing control system. As soon as the mains voltage experiences any fluctuation beyond normal parameters, the Gateway:

1. It identifies the anomaly within microseconds.
2. Initiates switching to the backup source (e.g. battery bank or generator).
3. Delivers power to the circuit without appreciable interruption, within 0 ms.

To achieve this, it combines high-speed current and voltage sensing elements with semiconductor switches that can change state almost instantaneously. This makes the difference to systems with mechanical relays or contactors, where the mechanical switching time is inevitably longer.

Key applications: factories and producers

• Automated production lines: Allows to keep the line running without breaks, increasing productivity and reducing waste.
• Agri-food sectors: In packaging or refrigeration processes, a power outage can mean raw material losses or conservation failures.
• Chemical or pharmaceutical processing plants: Energy stability is essential to avoid risks and maintain product quality.
• Audiovisual equipment in production companies: Power outages can ruin expensive and difficult-to-repeat recordings or live broadcasts.

A scalable system for your needs

What is most remarkable is that the Gateway HomeMax is not limited to a fixed output. Its different versions - from 24 kW single-phase to 1200 kW in three-phase systems - cover a very wide range of applications:

• Small residential installations with high consumption.
• Industrial buildings and large production complexes.
• Data centres and office buildings requiring absolute power continuity.​

In addition, its modular and scalable design philosophy facilitates future power upgrades or integration with batteries of different capacities, adapting to the growth of your business or your long-term energy needs.  

This success story demonstrates this: a SigenStor system consisting of a SigenStor EC 6 SP, two SigenStor BAT 8.0 units with 16 kWh of storage and the Sigen Gateway HomeMax, ensuring a continuous energy supply.
