Anker SOLIX C2000 Gen 2

Buy — 2,400 W continuous / 2,048 Wh LFP at 41.7 lb, expandable to 4,096 Wh; TT-30R rated 20 A; 4,000 W peak ≠ continuous; 120 V only

For a 2 kWh LiFePO₄ station that carries a fridge, network, furnace blower, and lights through a day-long outage, with one battery added later: 2,400 W continuous and 2,048 Wh.

Exact model A1783 (US listing SKU A17831A1, 120 V version). Not the live SOLIX F2000, not the live SOLIX C1000, and not the C1000 Gen 2 (A1763).

What it is

Portable power station: LiFePO₄ pack 2,048 Wh (51.2 V, 40 Ah), pure-sine inverter 2,400 W rated at 120 V / 60 Hz. NEMA 5-20R outlets and one TT-30R share that 2,400 W. Anker rates the TT-30R at 20 A / 2,400 W, not 30 A. Also two 140 W USB-C, one 15 W USB-C, one USB-A, and a 12 V car socket. 41.7 lb (18.9 kg), 18.1 × 9.8 × 10.1 in. Cycle claim 4,000 to 80%.

Recharge: AC 1,800 W max, 100% in 88 min on AC alone. Anker's 58 min figure needs AC plus solar together (2,600 W combined). Solar: one XT-60i port, 11–60 V, 17 A, 800 W max. UPS switchover 10 ms; bypass is limited by the 1,800 W AC input.

Idle draw: Anker claims 9 W. 9 W × 24 h ≈ 216 Wh a day (Outage Stack math).

Expansion: one BP2000 (Gen 2), 2,048 Wh, 15.3 kg (~33.7 lb), for 4,096 Wh total. Anker's UK datasheet also lists a BP3000 path to 5,120 Wh; confirm US compatibility before planning on it.

What it will actually run

Running watts first: 2,400 W continuous. Surge second: 4,000 W peak, not continuous.

Planning assumption (not manufacturer): usable Wh ≈ rated Wh × 0.85. 2,048 × 0.85 ≈ 1,741 Wh. At 500 W: 1,741 ÷ 500 ≈ 3.5 h. With one BP2000: 4,096 × 0.85 ≈ 3,482 Wh, about 7.0 h at 500 W. Trusted Reviews metered 1,763 Wh at a 2,400 W load (86%) and 1,790 Wh at 1,000 W (87%) on its UK test unit, so ×0.85 is slightly conservative.

Will run

A full-size fridge for about a day (check its daily kWh)
Modem, router, and ONT for days
LED lights
A gas furnace blower if its running and start draw fit
A microwave, coffee maker, or 1,500 W space heater in short runs
A sump pump at 120 V if its start draw fits under the peak

Skip, or measure first

240 V well pumps or anything dual-leg
An RV air conditioner plus a microwave on the TT-30R at once
Motor loads near 2,400 W running
A desktop or NAS through a 10 ms switchover
Charging below 32 °F

Specs that matter

Continuous: 2,400 W @ 120 V, shared across all AC outlets
Peak: 4,000 W; not continuous
Capacity: 2,048 Wh LFP; 4,096 Wh with one BP2000 (Gen 2)
RV outlet: TT-30R, rated 20 A
AC charge: 1,800 W, 100% in 88 min
Solar: 800 W max, 11–60 V, one port
UPS: 10 ms; idle 9 W
Weight: 41.7 lb; 120 V only

Who should skip it

You read "4,000 W" as what it runs all night.
You need 240 V for a well pump or dryer circuit.
You need more than 2,400 W continuous or more than one expansion battery.
You expect a full 30 A from the TT-30R. It is a 20 A source with an RV plug.
Your solar plan needs more than 800 W or a second input.

Verdict

Buy. Same 2,400 W continuous and 2,048 Wh as the live F2000, at 41.7 lb against 67.2 lb, with a TT-30R, a 10 ms UPS, a 9 W idle claim, and one-battery expansion to about 3.5 kWh usable. It delivers roughly 1.7 to 1.8 kWh at the outlet in Trusted Reviews' UK test, enough for a fridge, network, and blower through a normal outage. If the label is not A1783, this page does not apply.
