When professionally hooked up it immediately smoked and burnt up. The return process is very time consuming and you have to jump through 2 different companies to get a refund
I converted my 28-foot travel trailer to a 24 volt lithium battery and Aims 2kW inverter. My design required 2kW of power for appliances and computers, 3Kwh of battery capacity, and user-friendly plug-and-play convenience. The inverter/charger/transfer-switch is the best choice for a simpler low-cost solution, because of these combined functions. At $659, the Aims product is half the cost of those from Victron, Magnum, Xantrex, GoPower, etc. That's important as it's almost half the total cost.
I found this Aims inverter to be good, but with some limitations:
* Changing from AC Priority to Battery Priority requires a dip-switch. While you mostly want AC priority for charging batteries on andn off shore power, you might want Battery Priority if you have good solar panels, and metered electric on a monthly hookup. Must choose one or the other if the inverter is locked away.
* charger is 24V 30A, but I can't get it to push more than 19A. Still don't know why.
* Inverter won't fire up under shore power, with a totally flat battery.
* Inverter is not a hybrid, so won't allow combining 30A shore power and another 80A from the battery.
* cutoff voltage is only configurable at 20 or 21 volts, but i'd rather cut it off higher, like at 23 or 24. Out of luck.
* Support didn't respond to my request for help with transformer buzzing. (I discovered this issue was covered in the excellent user guide, so no issue, but why not respond to my tech-support request? It left me with doubts wheher I could rely on Aims in the long term.
Overall very satisfied with what I got for the price I paid, and FactoryPure had the best price, and fast 2-day delivery direct from the factory. Thanks!
