Outback, FX2524MT Inverter Charger Grid-Interactive/Off-Grid Renewable Energy System

Outback, FX2524MT Inverter Charger will change the direct current (DC) power from stored energy in batteries, and convert it into alternating current (AC) electricity that home, RV or Marine owners can use to power T.V.s, refrigerators other electronics.

To evaluate your power requirements look at the name plate of the largest electronic appliance you want to run then look at the watt and surge rating of the Outback, FX2524MT. Your inverters consistent power capacity and surge capacity should allow a + 25% calculation safety factor when measured against the highest energy demand of your appliance.

rv FX2524MT inverterIMPORTANT SAFETY INSTRUCTIONS: It is the responsibility of the purchaser to ensure that all products are installed and operated in accordance with local and national building codes as specific by the NEC (National Electric Code), UBC (Uniform Building Code) or IBC (International Building Code) and local utility company policy. This product is designed for indoor or protected compartment installations. DO NOT expose the inverter to rain, snow, moisture or liquids of any type. Use insulated tools to reduce the chance of electrical shock or accidental short circuits. Remove all jewelry such as rings, watches, bracelets, etc. when installing the Outback inverter or any other electronic gear. Always disconnect the batteries or energy source prior to installation or performing maintenance on the Outback, FX2524MT inverter. Live power may be present at more than one point since an inverter utilizes both batteries and AC electricity. Turning off the inverter may not reduce that risk. Always verify proper wiring prior to starting the inverter. Do not operate the inverter if it has been damaged. Always read and follow the manufactures installation and operating instructions for the Outback, FX2524MT inverter charger prior to installation and operation.
