Frequently Asked Questions

Is the Freedom SW3012 an inverter or a charger?
Both. It’s an inverter/charger — a 3000W pure sine wave inverter and a 150A multi-stage battery charger in one unit, with an automatic transfer switch that swaps between shore/generator power and battery power for you.

What size battery bank does the SW3012 need?
A 3000W inverter pulls heavy current, so plan for a substantial 12V LiFePO4 bank (commonly 300Ah or more) with appropriately sized cable and a Class T fuse. Use our Power Station Size Calculator to size the bank to your actual loads.

Can it run an RV air conditioner?
With 3000W continuous and 6000W surge, it can start and run many RV rooftop AC units and other motor-driven loads — provided your battery bank and wiring are sized to support the draw.

How fast does it recharge my batteries?
The built-in 150A multi-stage charger refills your bank quickly whenever you’re connected to shore power or a generator — no separate charger needed.

Does it need a remote panel?
It runs standalone, but the Xantrex SCP remote panel adds at-a-glance status and control from inside your rig.

• Renogy 12V 300Ah Mini Lithium Battery
