High-Performance PSI 4.3L Liquid-Cooled Engine

En el núcleo del generador hay un Power Solutions International (PSI) 4.3-liter V6 engine.

This engine delivers several advantages compared with smaller air-cooled systems.

Lower Engine Speed

The engine operates at 1800 RPM, which reduces:

• Mechanical wear

• Heat generation

• Fuel consumption

• Operating noise

Many small standby generators run at 3600 RPM, which leads to faster wear and louder operation.

Funcionamiento silencioso

Despite its high output, the generator produces only 68 dBA sin carga, making it surprisingly quiet for its size.

This makes it suitable for residential neighborhoods where noise restrictions may apply.

Liquid Cooling System

El generador de reserva refrigerado por líquido design maintains stable operating temperatures even under heavy load.

Los beneficios incluyen:

• Mayor vida útil del motor

• Improved reliability

• Better performance in extreme climates

---

Flexible Fuel Options for Reliable Power

The generator operates using two fuel sources:

• Propano (GLP)

• Gas natural (GN)

This flexibility allows installation in a wide range of locations.

Propane Power Output

• 48kW output

• Approx. 6 gallons per hour at full load

Natural Gas Power Output

• 45kW output

• Approx. 511 cubic feet per hour at full load

For many property owners, natural gas is preferred because it provides a continuous supply without refueling. Propane, however, offers greater independence from local utility lines.

Both options make the unit a reliable generador de reserva de propano o generador de reserva de gas natural depending on installation requirements.

Tecnología de gestión de energía Symphony II

One of the most advanced features of this generator is Gestión de energía de Symphony II.

This intelligent system automatically distributes available electricity across selected circuits.

What this means in practice

Without load management, generators can shut down if too many appliances run simultaneously.

The Symphony II system solves this by:

• Monitoring electrical demand

• Prioritizing critical appliances

• Preventing overload conditions

For example, it can temporarily delay non-essential appliances while essential systems continue operating.

This makes the generator far more efficient when used as a generador de respaldo para toda la casa.

---

Durable Automotive-Grade Enclosure

Standby generators operate outdoors year-round, which means they must withstand harsh environmental conditions.

The Fortress series uses acero galvanizado de calidad automotriz for the enclosure.

Los beneficios incluyen:

• Resistencia excepcional a la corrosión

• Durabilidad a largo plazo

• Protection from rain, snow, and humidity

• Improved structural strength

The enclosure design also helps reduce sound levels during operation.

---

Fácil acceso para mantenimiento y servicio.

Una gran ventaja de la Briggs and Stratton generator design is simplified maintenance.

Technicians can access the engine quickly without removing large sections of the enclosure.

This reduces service time and ensures routine maintenance can be completed efficiently.

Maintenance access points include:

• Engine components

• Oil and coolant systems

• Electrical connections

Routine maintenance typically includes:

1. Cambio de aceite y filtro

2. Inspección del refrigerante

3. Battery checks

4. Sustitución del filtro de aire

5. System diagnostics

Proper maintenance significantly extends the generator’s operational lifespan.

---

Smart Monitoring with InfoHub Wireless Technology

Modern standby generators benefit from remote monitoring.

The optional Sistema de monitorización inalámbrica InfoHub allows owners to track generator status from a smartphone or computer.

Capabilities include:

• Generator status monitoring

• Recordatorios de mantenimiento

• System alerts

• Performance tracking

This is especially valuable for businesses that rely on continuous power availability.

---

Installation Flexibility

Another advantage of the Generador Briggs and Stratton Fortress de 48 kW, monofásico, 120/240 V. is its flexible installation capability.

The generator can be installed as close as 18 inches from a building, depending on local codes.

This provides more options for:

• Residential installations

• Commercial facilities

• Limited outdoor spaces

However, installation must follow all electrical and building regulations.

Professional installation by a certified technician is strongly recommended.
