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	DELTA 3	Yeti 1000	What it means
Capacity	1,024 Wh	998 Wh	How much energy the unit stores. Sets how long everything else can run.
Continuous AC output	1,800 W	2,000 W	The largest load the inverter will run continuously, not counting surge.
Weight lower is better	27.6 lb	35.3 lb	The spec buyers most often regret ignoring.
List price lower is better	$629	$1,200	Vendor list price at the time of collection; street prices move.
Cost per watt-hour lower is better	$0.61	$1.20	Price divided by capacity. The fairest single value metric.
Watt-hours per pound	37.1 Wh/lb	28.3 Wh/lb	Capacity you get per pound carried.
Max solar input	500 W	900 W	Caps how large an array is useful, and therefore off-grid recharge speed.
AC recharge time lower is better	56 min	72 min	Vendor-stated time to full from a wall outlet.
Rated cycles	4,000 cycles	4,000 cycles	Vendor claim for charge cycles before capacity degrades to 80%.
UPS switchover lower is better	10 ms	15 ms	How long the unit takes to switch to battery. Under 20 ms keeps a desktop alive.
Max expandable capacity	5,000 Wh	—	How far the system can grow with add-on batteries.
Warranty	60 months	60 months	Stated warranty length from the vendor listing.
