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	RIVER 2 Max	E500LFP	What it means
Capacity	512 Wh	576 Wh	How much energy the unit stores. Sets how long everything else can run.
Continuous AC output	500 W	600 W	The largest load the inverter will run continuously, not counting surge.
Weight lower is better	13.4 lb	15.0 lb	The spec buyers most often regret ignoring.
List price lower is better	$249	$269	Vendor list price at the time of collection; street prices move.
Cost per watt-hour lower is better	$0.49	$0.47	Price divided by capacity. The fairest single value metric.
Watt-hours per pound	38.2 Wh/lb	38.4 Wh/lb	Capacity you get per pound carried.
Max solar input	220 W	100 W	Caps how large an array is useful, and therefore off-grid recharge speed.
AC recharge time lower is better	60 min	90 min	Vendor-stated time to full from a wall outlet.
Rated cycles	3,000 cycles	3,500 cycles	Vendor claim for charge cycles before capacity degrades to 80%.
UPS switchover lower is better	30 ms	—	How long the unit takes to switch to battery. Under 20 ms keeps a desktop alive.
Warranty	60 months	12 months	Stated warranty length from the vendor listing.
