Our cabin is completely off grid. We survive on a 1600 kW solar system with a large battery pack that is hooked to a propane generator when the sky is grey and winter days are short. This inverter is the heart of the system. Mine has been in operation for 7 years without a hitch. I have a back up in the barn. I highly recommend it. ... show more

    • Easy upgrade from a 458 D20

If you're like me and have a recently deceased 22+ year old Freedom Combi 458 (with dual external breakers on your front case) you're stuck considering a replacement. We are full time RVers who primarily boondock, our inverter is heavily used and I wanted an easy upgrade path. The SW3012 went in easy and the only slight modification was the tip I got from Xantrex to jumper the primary AC input 1 to the secondary AC input 2 as my Freedom 458 was single in dual out. This properly activates both outputs and apart from this slight modification the install was no harder than matching wires to their ports. I ended up mounting it horizontal to expose the ports better in my small electrical bay. ... show more

    • NO Customer Service
Style: 3000 Watt Product Packaging: Standard Packaging
Absolutely (0) None customer support. I received the product with no issues and installed it without difficulty - this is my third inverter/charger. The first died of old age. The second lasted six years before it got wet and killed the controller boards. This one should have been a drop-in no-brainer. The problem began when it would not recognize a 'Validated' power source - meaning 110v shore power. Yeh, tell me what that means? The documentation was as clear as MUD and there was absolutely NO trouble shooting instructions other than to "factory reset". This meant it ran in inverter mood, which work perfectly, but I could not charge my batteries. Yes I tested the power all along the path, and at connection points to the inverter I got ~120v ground to hot and hot to neutral and 0v neutral to ground. So I thought, let me call customer support in inquire about what the hell a 'valid' power source is. Fourteen (14) calls over 4 days later I never spoke to a single person. I left call-back a number as instructed and waited for a call-back. NOPE. At one point I was third in the queue at 09:00 and never got a call back. I thought I would out-smart the system and call the Sales department, they will always answer...I was first in the queue but had to leave a call-back number after holding for ~45 minutes. Never got a call-back! I'm sure the product is great and my problem was something simple but not covered in the installation and troubleshooting guide, but...I don't care how good the product is, without customer service it is worthless. Oh, not to mention the almost $700 restocking charge. This was very expensive lesson. I have wasted many days, and dollars, with this product and can't recommend it to anyone for any reason. Before I purchased my second choice inverter/charger from AIMS Power I called their support line and got a technician on the second ring. He is probably still laughing after I told him why I was calling. PS. I did receive a call-back at 21:00 two days after I had shipped the product back. ... show more

Inverter replaced another Xander Freedom inverter we had in our Rv. It’s working great so far! We had it installed by a RV specialist to make sure everything was hooked up properly. Happy with the purchase. We might have been able to install it, but didn’t want to take a chance. As for the value! Yikes, everything has gone up. ... show more

Even after checking the arrival date, and wow to my surprise the inverter arrived today on a Friday instead of the Monday projected delivery date. Great! Thank you. The inverter is not connected yet, but I expect it will work at least as well as the one I'm replacing. I appreciate the seller sending it so quickly. Zantrex is high quality and pricey, but yo get what you pay for. ... show more

This invertor works flawlessly. It's so fast in transfers that you really don't notice it happened. Not like my old one. I'm so happy with it that I know I'd do it again given the choice.
