The EM2500-24L and EM3500-24L are ideal for family farms, powering tools, lighting, and basic appliances. Native LiFePO4 support ensures long-term, low-maintenance storage. The wide MPPT voltage range (60-500VDC) allows flexible panel configurations in partially shaded agricultural settings.
In the solar-rich Atacama Desert, the EM1500-24L provides ultra-reliable power for remote telemetry and mining camps. Its high efficiency maximizes yield. In the cooler south, the EM3500-24L can power a remote homestead, with its operational range handling temperature variations.
The EM5500-48L serves as a community power hub for schools or health posts. The "No Battery Mode" enables direct solar-powered operations during the day—a simple, cost-effective model for community centers.
For off-grid lodges or farms, the EM6200-48L delivers ample power for guest comforts and operational needs. Its high AC charge current (80A) allows for rapid battery replenishment from a backup generator when solar is insufficient.
Match the model to the terrain and primary load. For motor-driven loads (pumps), emphasize high surge power. The universal 50/60Hz auto-sensing is vital for regions with varying grid standards. The EM5500-48L often represents the best balance for robust off-grid living.
