I first bought a power jack 60000w/15000w inverter. it had a whopping 8 pages half were Chinese girls in bikini, for 600us. After that, you know why ETL UL and CSA are there. . the sma was 235 pages. no girls, true german product over-engineered and leave nothing in detail for the consumer. like there cars for service. what a well-built machine. SMA 08 hate to ask what that goes for> I preferred $1500 for the 6048. along with really poor packaging and ups to drag it around. beat the hell out of it, built like a tank, weight 160lbs like the BYD batteries.
The latest update claims it accepts lithium batteries even has byd in its thumbs up.
