System standby power: 22W (31.2% of total draw)
Provides 4× CEE 7/3 (230V), 1× IEC Commando (32A) (120V 60Hz).
Pure sine wave inverter output. Safe for all standard household appliances.
Electronic/resistive load with 1.1× start-up profile (99.3% surge margin).
Wall AC fast charge at up to 1800W (120m to 80%, 150m to 100%).
Safe envelope verified: Starting surge (50W) remains comfortably below the 7200W surge trip line, with steady-state operation settling into the safe continuous zone at 45W.
About 57 hours on AC power, with the home network rack averaging 45 W (Fiber ONT + Wi-Fi 6 router + 4 PoE IP security cameras + NVR recorder (45 W)). The Goal Zero Yeti PRO 4000 then draws about 71 W from its battery, including 22 W for the inverter itself. Best case: about 3.1 days (Fiber ONT optical modem + managed 8-port gigabit switch (30 W)). Worst case: about 39 hours (Managed 16-port PoE switch + 8 cameras + local NAS storage server (75 W)).
Yes. Using the 12V DC Regulated Terminal / Barrel Power Kit on the Goal Zero Yeti PRO 4000's 12 V car socket, the home network rack runs about 3.8 days instead of 57 hours on AC, 62% longer, because it skips the inverter's conversion loss and its 22 W idle draw.
That simple division gives 3.7 days, but the Goal Zero Yeti PRO 4000's inverter draws about 22 W whenever its AC outlets are on. At this light load that's 31% of everything the battery supplies, and inverter conversion losses take a further share. The idle figure comes from Goal Zero.
On wall power: about 120 minutes to 80% and 150 minutes to full (Goal Zero figures). With its maximum 3,000 W of solar input connected, expect about 2,400 W in full sun, so a full recharge takes roughly 1.8 hours of full sun, so it can refill in a single day with 4 peak sun hours.
It can act as a backup supply: with the home network rack plugged into the Goal Zero Yeti PRO 4000 and the Goal Zero Yeti PRO 4000 plugged into the wall, it switches the home network rack to battery in about 10 ms when the grid fails (Goal Zero calls this UPS mode).
