Latest Update: ALL ISSUES RESOLVED!!!!!
The new updated unit arrived today from Aims and it works great out of the box.
My Craftsman Generator at 5500 Watt 6500 Watt peak charges at the 90 amp rate as it should.
The smaller Champion 3500 Watt just can't do it.
I would recommend getting a generator of at least (6000 Watt)the same output as the inverter.
We are 100% off the grid and this unit is working great.
I can say that I would now definitely recommend unit to anyone in the market for a great 240 Volt inverter charger.
The guys at Aims support have gone above and beyond in helping me resolve my issues listed below and I can't say enough good about them. Thanks Sean and Andrew.
It is rare to get that kind of support and I appreciate it greatly.
I am leaving the below posts just for reference as ALL ISSUES HAVE BEEN RESOLVED!!!!!
-----------------------------------------------------------------------------------------------------------------------
I have been in contact with Aims support on 2-25-13.
We have since changed a few parts which did not correct the issue with this particular inverter.
Aims support is and have been excellent throughout this experience and have shipped me a new unit to replace the defective one. I will update my generator testing after I get it installed.
Their comment prompted me to call in to support and inquire about the new upgrade.
They are shipping me a new board which is designed to support a wider input range to support generator AC charging.
I will be posting an update as soon as it is tested.
I have to say the support was great originally and still seems to be.
Thanks Aims Support.
Original post:
Don't be fooled into buying this for an off grid application. UPDATE Below.
This unit came in a box that looked like it was dragged instead of transported inside a truck. (refused to sign for UPS Delivery) Tried to install as no visible damage on the surface.
The manufacturer is filing a claim with UPS and shipping me a replacement. I will update this review as the process evolves.
I spent hours with support (they seemed to be genuinely interested in getting this up and running) to get the inverter connected.
After connected I found out that I was mislead by an uninformed salesman who told me I could charge the batteries with my new Honda EU2000 120 v generator which was incorrect.
I then tried to charge the batteries with my Craftsman 5500 watt generator.
This was also a bust as the inverter was too picky about the power being delivered and would never go to line power to start the charge process. This was a 12 year old generator.
I gave up and went to TSC and bought a 3rd generator a 3500 watt Champion.
This generator would get the inverter to switch to line power and start what was indicated as a fast charge.
This fast charge never put any power in my batteries over two days of trying on gen power.
I am optimistic that will be resolved, but I am initially disappointed with this unit.
The worst part of this is that I spent 6 hours on support on a Friday before a long weekend so I am without it for at least 3 days before I can even get support. 24/7 support would be nice on a $1800 unit.
The manual for the inverter and is poorly written mostly due to a bad translation.
UPDATE:
The new unit was shipped freight.
I got it and hooked it up. Looked promising.
It performs great as an inverter. I have still had issues charging batteries with it.
I have now tried the following.
1. A new EU6500is Honda which outputs too much power to be seen as line power at 253-257 volts. This just shows as abnormal line power and never switches out of inverter mode and never starts a charge. I was able to rent this for a day luckily.
2. A new Champion 3500w which will switch to line power, but falls out of the range for frequency.
3. My 12 year old Craftsman 5500w which with a lot of adjusting will switch to line power and start a charge, but can only charge at the lowest charge setting and takes hours and hours to charge. It also kicks out of line mode if the fridge or well calls for power.
My best charging option up to this point is a 30A 24V charger that I bought at NAPA for an additional $350 and connect to my EU2000 120v Honda generator.
This will at least consistently put power into the system while in use.
I would not recommend this to others.
I would buy a straight inverter and then buy a charger since the input is so picky that it doesn't charge at the rate needed to make it practical.
Aims Tech Support has now confirmed that this unit requires line power not generator power to charge batteries.
That is great since this was purchased for an off grid application based on sales pitch from the inverter store.
Don't be fooled.
Thanks

I purchased this inverter at the advice of a friend who found it online. I was a little hesitant to buy it based on the review on Amazon, as I use it in an off-grid cabin. I took a chance and bought the unit, after Theinverterstore.com Sales team explained that the unit had been upgraded with a new input range to work with most generators.
I am happy that I bought this unit and it is working Great! I am off-grid with a generator and have had no issues; it runs everything in my cabin without issue.
By the way I am using it with a generator and an array of 100 watt solar panels.
I would recommend the unit.
