Short answer: BLUETTI wins on solar input and UPS speed at 240V, Anker SOLIX wins on output and weight at 2 kWh and on the whole-home size. At 1 kWh the BLUETTI Elite 100 V2 (about $499) takes 1,000 W of solar against 600 W on the Anker SOLIX C1000 Gen 2 (about $500), while the Anker runs 2,000 W against 1,800 W. At 2 kWh the Anker C2000 Gen 2 is 11.7 lb lighter than the Elite 200 V2 and expands. For 240V home backup the Anker F3800 Plus gives 6,000 W and 3,840 Wh against 3,840 W and 2,765 Wh on the BLUETTI Apex 300, which is 53 lb lighter.

Every unit here uses LiFePO4 cells and a pure sine wave inverter. Runtimes use the site formula: capacity x 0.85 for inverter losses, divided by the average draw. A full-size fridge averages about 52 W, so a 1,024 Wh unit gives 1,024 x 0.85 = 870 Wh, and 870 / 52 = about 17 hours of fridge.

1 kWh: C1000 Gen 2 vs Elite 100 V2 vs AC180
Anker SOLIX C1000 Gen 2: 1,024 Wh, 2,000 W (3,000 W surge), 4 AC outlets, 600 W solar, 10 ms UPS, 24.9 lb, about $500. BLUETTI Elite 100 V2: 1,024 Wh, 1,800 W (3,600 W surge), 4 AC outlets, 1,000 W solar, 10 ms UPS, 25.3 lb, about $499. BLUETTI AC180: 1,152 Wh, 1,800 W (2,700 W surge), 4 AC outlets, 500 W solar, 20 ms UPS, 35.3 lb, about $499.
The C1000 Gen 2 and Elite 100 V2 are nearly the same box: same capacity, same outlet count, same 10 ms UPS, 0.4 lb apart. The Anker has 200 W more continuous output. The BLUETTI has 600 W more surge and 400 W more solar input, so it refills in about 1.4 hours of full sun (1,024 / 750) against about 2.3 hours (1,024 / 450). None of the three expands.
The AC180 holds 128 Wh more, about 19 hours of fridge (1,152 x 0.85 = 979 Wh, / 52) against 17. You pay for that in 10 lb more weight and a 20 ms UPS.
BLUETTI Elite 100 V2

2 kWh: C2000 Gen 2 vs Elite 200 V2 vs AC200L
Anker SOLIX C2000 Gen 2: 2,048 Wh, 2,400 W (4,000 W surge), 4 AC outlets plus a TT-30 RV outlet, 800 W solar, 10 ms UPS, 41.7 lb, expands to 4,096 Wh with one BP2000, about $900. BLUETTI Elite 200 V2: 2,074 Wh, 2,600 W (3,900 W surge), 4 AC outlets, 1,000 W solar, 10 ms UPS, rated for 6,000 cycles, 53.4 lb, not expandable, about $899. BLUETTI AC200L: 2,048 Wh, 2,400 W (3,600 W surge), 4 AC outlets plus a 30 A RV outlet, 1,200 W solar, 20 ms UPS, 62.4 lb, about $899.
The Anker is the one to carry: 11.7 lb lighter than the Elite 200 V2 and 20.7 lb lighter than the AC200L, with the highest surge of the three. The Elite 200 V2 has the biggest inverter (2,600 W). The AC200L has the most solar input and the highest expansion ceiling: BLUETTI lists up to 8,192 Wh, and two of the B300K packs we link take it to about 7.6 kWh.
Each runs a 52 W fridge about 33 to 34 hours per charge (2,048 x 0.85 = 1,741 Wh, / 52). Expanded, the C2000 Gen 2 reaches about 67 hours and an AC200L with two B300K packs about 124 hours. Solar refill in full sun: about 3.4 hours for the Anker (2,048 / 600), 2.8 for the Elite 200 V2 and 2.3 for the AC200L.

Whole-home 240V: F3800 Plus vs Apex 300
Anker SOLIX F3800 Plus: 3,840 Wh, 6,000 W (9,000 W surge), 120/240V, 8 AC outlets, 3,200 W solar, 20 ms UPS, 137 lb, expands to 26,880 Wh with up to six BP3800 batteries, about $2,400. BLUETTI Apex 300: 2,765 Wh, 3,840 W (7,680 W surge), 120/240V, 6 AC outlets, 2,400 W solar, 10 ms UPS, 84 lb, expands to 19,354 Wh with up to six B300K packs, about $1,599.
The F3800 Plus runs 56 percent more continuous watts and holds 1,075 Wh more in the base unit: about 63 hours of fridge (3,264 Wh / 52) against about 45 hours (2,350 Wh / 52). The Apex 300 is 53 lb lighter and switches in 10 ms instead of 20. Both surge high enough to start a 1/2 HP 240V well pump.
Expansion adds 3,840 Wh per Anker BP3800 (about $1,800) or 2,765 Wh per BLUETTI B300K (about $1,199). Fully expanded, the Anker reaches about 18 days of fridge alone and the BLUETTI about 13. Anker also sells the Smart Home Power Kit (about $1,200) to switch chosen circuits automatically; plan on a licensed electrician.

How to choose between the brands
Charging from solar: BLUETTI at 1 kWh and 2 kWh. Carrying the unit or adding a battery at 2 kWh: Anker. Whole home: count the watts that must run at once. Over 3,840 W, only the F3800 Plus covers it. Under that, the Apex 300 is lighter and quicker on UPS.
Warranty terms change by model and store. Check the current terms on the Anker SOLIX and BLUETTI product pages before you order.

Frequently asked questions
Is Anker SOLIX better than BLUETTI?
At 1 kWh BLUETTI's Elite 100 V2 has more solar input (1,000 W vs 600 W) and surge, while the Anker C1000 Gen 2 has the bigger inverter (2,000 W vs 1,800 W). At 2 kWh the Anker C2000 Gen 2 is the lightest and expands, and the BLUETTI Elite 200 V2 has the bigger inverter. For 240V, the Anker F3800 Plus has more output and battery, and the BLUETTI Apex 300 is lighter with a faster UPS.
Anker SOLIX C1000 Gen 2 vs BLUETTI Elite 100 V2: which should I buy?
Both hold 1,024 Wh with four AC outlets and a 10 ms UPS, at 24.9 lb and 25.3 lb. Buy the Anker (about $500) for 2,000 W continuous. Buy the BLUETTI (about $499) for 1,000 W of solar input and 3,600 W surge.
Anker SOLIX C2000 Gen 2 vs BLUETTI Elite 200 V2: which is better?
The C2000 Gen 2 weighs 41.7 lb against 53.4 lb, has 4,000 W surge and expands to 4,096 Wh. The Elite 200 V2 runs 2,600 W continuous against 2,400 W, takes 1,000 W of solar against 800 W, and is rated for 6,000 cycles, but it does not expand.
Anker SOLIX F3800 Plus vs BLUETTI Apex 300: which is better for home backup?
The F3800 Plus has 6,000 W continuous and 3,840 Wh against 3,840 W and 2,765 Wh, and expands to 26,880 Wh against 19,354 Wh. The Apex 300 weighs 84 lb against 137 lb and switches in 10 ms against 20 ms. Both output 120/240V for a well pump.
How long will an Anker SOLIX or BLUETTI run a refrigerator?
About 17 hours on a 1,024 Wh unit, 19 hours on the BLUETTI AC180, 33 to 34 hours on a 2 kWh unit, 45 hours on the BLUETTI Apex 300 and 63 hours on the Anker F3800 Plus, for a fridge averaging about 52 W. That is capacity x 0.85 / 52.
How long will an Anker SOLIX or BLUETTI run a CPAP?
About 22 hours on a 1,024 Wh unit (C1000 Gen 2 or Elite 100 V2), 24 hours on the AC180 and 43 to 44 hours on a 2 kWh unit, for a 40 W CPAP with the humidifier off. A heated humidifier raises the draw and cuts those hours.
Which charges faster from solar, Anker SOLIX or BLUETTI?
BLUETTI at 1 kWh and 2 kWh. Using Wh / (solar input x 0.75), the Elite 100 V2 refills in about 1.4 hours of full sun against 2.3 for the C1000 Gen 2, and the AC200L in 2.3 hours against 3.4 for the C2000 Gen 2. At 240V they are close: about 1.6 hours for the F3800 Plus and 1.5 for the Apex 300.
Which is lighter, Anker SOLIX or BLUETTI?
Anker at 2 kWh, BLUETTI at 240V. The C2000 Gen 2 is 41.7 lb against 53.4 lb for the Elite 200 V2 and 62.4 lb for the AC200L. The Apex 300 is 84 lb against 137 lb for the F3800 Plus. At 1 kWh they are 0.4 lb apart.
Can an Anker SOLIX or BLUETTI run a well pump?
A 240V well pump needs the Anker F3800 Plus or the BLUETTI Apex 300, both of which output 120/240V and surge to 9,000 W and 7,680 W. The 1 kWh and 2 kWh units are 120V only, so they suit a 120V jet pump at most.
