Bought one on BF for about this price. Added 2 more batteries. It's 9600 watt hours now. I charge it from a Solar array and use it to for my shop. I hoped to also throw it in the rv for silent power but it's just too darn heavy and not really silent. Yes it does have lithium iron phosphate batteries ( and the batteries are really nice).
Pros:
Powerful,
easy to expand capacity,
Price per watt is good
Supports 4400watts of total Solar in 2 separate arrays (2 mppt md4 connectors)
Batteries have built in heaters and communication ports
Cons:
Very heavy (esp with 2 extra batteries sitting on top of the unit),
Loud. When this is charging/discharging the fans in the inverter really get humming (typical with most inverters but way more than say a portable battery pack,
Only can do 120v - no way to add 240v split phase to this
No way to grid-tie and sell back power (if your state and utility co allow it)
Solar pass-through only supports 1500 watts before augmenting with batteries. So if you have >3000 watts of solar available and fully topped up batteries you're still going to discharge and wear cycle the batteries if you run high wattage appliances (or multiple low wattage stuff)
Narrow voltage range for solar panels (60-150v) which means you have to be careful how your series/parallel your arrays)
I like mine, but don't know if I would go the same route if I could do over. Probably would go with the Ecoflow delta pro double voltage pack that's currently on sale at Home Depot.
