Usability
3.5 out of 10At 3,500 W continuous it sits on the 3,500 to 4,999 W rung for a 48 V all-in-one, so it scores 3 on capacity.
Better on capacityLiTime 48V 5kW All-in-One Inverter$699.99Scores 5.0LiTime rates its inverter efficiency above 91 percent, which meets the 6 rung, and its normal-mode no-load draw under 50 W is 14.3 W per kW of its 3,500 W rating, which meets the 4 rung (ECO mode under 30 W is 8.6 W per kW), so with one input on each rung it scores 5 on efficiency.
Its 6,000 W surge for 5 seconds is 1.7 times its continuous rating, so it scores 3 on operating range.

No certifier directory lists this unit (Intertek, UL, CSA, LabTest, TÜV, SGS), and LiTime's page and manual name no safety listing, so it scores 2 on verification.
