Spec by spec

A green arrow marks the better figure on each row. Rows where only one unit publishes a number are shown without a winner rather than guessed.

Metric	F3000 2	Mega 3	What it means
Capacity	3,072 Wh	3,072 Wh	How much energy the unit stores. Sets how long everything else can run.
Continuous AC output	3,600 W	3,600 W	The largest load the inverter will run continuously, not counting surge.
Weight lower is better	91.5 lb	83.3 lb	The spec buyers most often regret ignoring.
List price lower is better	$2,800	$1,199	Vendor list price at the time of collection; street prices move.
Cost per watt-hour lower is better	$0.91	$0.39	Price divided by capacity. The fairest single value metric.
Watt-hours per pound	33.6 Wh/lb	36.9 Wh/lb	Capacity you get per pound carried.
Max solar input	2,400 W	2,100 W	Caps how large an array is useful, and therefore off-grid recharge speed.
Rated cycles	4,000 cycles	3,500 cycles	Vendor claim for charge cycles before capacity degrades to 80%.
UPS switchover lower is better	—	20 ms	How long the unit takes to switch to battery. Under 20 ms keeps a desktop alive.
Max expandable capacity	24,000 Wh	15,360 Wh	How far the system can grow with add-on batteries.
Warranty	60 months	60 months	Stated warranty length from the vendor listing.
