ENERGY WITHOUT THE GRID
Off-grid solar systems engineered to keep running
Generation, batteries, starting power and auxiliary backup within an architecture validated to operate without the electricity grid.

MORE THAN PANELS AND A BATTERY
An off-grid system is designed for the worst day, not the annual average
The lowest-resource month, night consumption, motor starts and loads that cannot fail determine the architecture. The aim is not to accumulate equipment: it is to balance energy, power and reserve.
OFF-GRID ARCHITECTURE
From solar resource to critical load
Every block must operate within the limits of the next one. Final selection depends on real data and current documentation.
PV generation
Modules, structure, orientation and critical-month resource.
Conversion and charging
Inverter/charger, MPPT and instantaneous power.
Energy storage
Usable capacity, discharge rate, BMS and reserve.
Protection and control
Panels, isolation, EMS and monitoring.
Critical loads
Priorities, starts and load-shedding sequence.
CONDITIONAL LAYER
Compare AC and DC architecturesAuxiliary source, ATS and coupling
Added when continuity or the load profile requires it; it is not a universal component.
APPLICATIONS
Three scenarios. Three different designs.
The same battery does not solve a pump, a remote station and accommodation with night demand in the same way.
Agriculture and pumping
Motors, schedules, seasonality and water availability shape the power requirement and operating strategy.
Telecoms and remote infrastructure
Continuity, redundancy, maintenance access and monitoring matter as much as daily energy.
Accommodation and off-grid business
Night consumption, HVAC, kitchens and user experience require load prioritisation and backup planning.
Conceptual visuals of off-grid applications; every project requires specific validation.
DATA BEFORE EQUIPMENT
What we need to close the sizing study
The better the load profile, the less uncertainty must be covered by conservative assumptions.

A public off-grid hotel project shows why generation, storage and backup must be designed as one system.

Share consumption, peaks, location and target autonomy. The final BOQ is technically validated before a proposal is prepared.
The importance of quality technical service
Making an isolated installation successful is no easy task, which is why it is essential to have safe, reliable, high-quality equipment in order to avoid problems.
Furthermore, setting up a stand-alone installation is usually more complex than one connected to the grid. However, with good technical equipment and an understandable product, it can even be the opposite.

Preguntas frecuentes sobre instalaciones solares aisladas
Respuestas para profesionales · Información actualizada el 13 de agosto de 2026.
¿Cuándo tiene sentido una instalación solar aislada?
Es adecuada cuando no existe red eléctrica, la red es inestable o el proyecto necesita autonomía. La generación y el almacenamiento deben dimensionarse para los consumos y condiciones más exigentes.
¿Qué datos son necesarios para dimensionarla?
Se necesitan consumos diarios, potencias de arranque, horas de uso, autonomía deseada, ubicación, recurso solar y cargas críticas. También debe definirse si habrá una fuente auxiliar.
¿Por qué no basta con elegir una batería grande?
El sistema debe equilibrar generación, conversión, capacidad útil, potencia instantánea y gestión de cargas. Sobredimensionar un componente no corrige una arquitectura inadecuada.
