Key Features of the Fortress II: Adaptable to Harsh Environments: Designed for wet and tough conditions, ideal for outdoor use in backyards, boats, docks, and more. Capable of withstanding rain, sleet, snow, mud, and high-pressure washdowns. Waterproof exterior connections perfect for outdoor use. Enhanced Power and Storage: Features larger inverter output sizes ranging from 3000W to 5000W and additional battery space compared to import models, catering to more demanding power needs. Being able to supply your own battery, or use our battery makes this solar generator one of the best and least expensive options on the market. Mobility and Ease of Use: Equipped with wheels and a high-leverage handle for effortless transportation despite its increased weight. Pre-assembled with easy battery connection setup (if ordered with batteries). Innovative Inverter Design: The inverter is strategically mounted on the lid or near the top with stainless/rubber sealing washers, minimizing water exposure. Internal mounting of all electronics, ensuring no exposed wiring and better protection from elements. Advanced MPPT Solar Charge Controller: Utilizes a specially potted solar charge controller for water resistance, shock protection, and efficient heat distribution. Bluetooth and compatible with various battery types, allowing users to supply their own or choose "With Batteries" option. Ventilation with Special Covers: Airflow vents are designed with unique covers to prevent water ingress while allowing necessary ventilation. Temperature-controlled fans for cooling. Weep Holes for Water Escape: Incorporated weep holes facilitate the escape of any water that enters the housing, preventing damage from condensation. Built with Precision in the USA: A Commitment to Quality and Craftsmanship.
