Off-Grid Inverters

Los inversores de aislada trabajan sin red eléctrica y convierten la energía DC de baterías y/o paneles en AC para la vivienda, caseta o embarcación. Son la base de los sistemas solares aislados, con opciones simples o con cargador y regulador integrados.

Disponemos de modelos en 12V, 24V y 48V, con versiones con cargador y con cargador + MPPT para simplificar la instalación. Explora las subcategorías:

What is an off-grid inverter?

An off-grid inverter converts the energy in direct current (DC) stored in batteries or coming from photovoltaic panels into alternating current (AC) to power appliances and equipment without relying on the public grid. It is the heart of off-grid solar systems, whether in rural homes, cabins, caravans, or boats.

Types of off-grid inverters

12V, 24V and 48V: chosen according to power and battery bank size.
With charger (12/24/48V): allow charging batteries from a generator or auxiliary grid.
With charger + MPPT: integrate the MPPT solar charge controller to connect panels directly and simplify the system.
With MPPT: models that incorporate internal photovoltaic regulation.

How to choose the right model

Power (kW): calculate simultaneous loads and allow margin for start-up peaks.
System voltage: 12V for low power; 24V intermediate; 48V for medium/high consumption.
Functions: integrated AC charger, integrated MPPT, source priority, protections, and monitoring.
Efficiency and waveform: prioritize pure sine wave and high performance at partial load.
IP rating: indoor dry installation or demanding environments depending on the model.

Accessories and complements

Complete your system with battery banks (AGM, GEL, stationary, or lithium), MPPT charge controllers when not integrated, battery monitors (shunt), and inverter accessories (wirebox, meters, CTs).

With a properly sized off-grid inverter you will achieve autonomy, safety, and efficiency in your off-grid installation. Explore the subcategories to find the perfect equipment: 12V, 24V, 48V, with charger, and with charger + MPPT.
