Quick answers

Is the Anker SOLIX C2000 Gen 2 better than the Anker SOLIX S2000?: Anker SOLIX C2000 Gen 2 leads by 27 points overall.
Which has more usable capacity, the Anker SOLIX C2000 Gen 2 or Anker SOLIX S2000?: Neither, in any way you would notice: 1,761 Wh against 1,709 Wh is a 3% gap, which is smaller than the swing you get from running the same load on a cold morning. Treat them as the same size and decide on output, weight, or today's price instead. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices.
Which has more AC output, the Anker SOLIX C2000 Gen 2 or Anker SOLIX S2000?: The Anker SOLIX C2000 Gen 2: 2,400 W versus 1,500 W continuous. That gap matters only if a load sits between the two numbers — below 1,500 W both run it, above 2,400 W neither does. Surge headroom follows the same order: 4,000 W against 3,000 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX C2000 Gen 2 and Anker SOLIX S2000?: They run within 3% of each other on the same load — about 28 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
Which is lighter, the Anker SOLIX C2000 Gen 2 or Anker SOLIX S2000?: The Anker SOLIX S2000, by 2.7 kg (16.2 kg versus 18.9 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
Which recharges faster from the wall, the Anker SOLIX C2000 Gen 2 or Anker SOLIX S2000?: The Anker SOLIX C2000 Gen 2: 88 minutes from empty to full against 138 minutes, a difference of 50 minutes. This matters most between outages and during a short grid window — if you only ever recharge overnight, it does not matter at all.
Which model should I buy for my use case?: On the sub-scores that describe each use case: the Anker SOLIX C2000 Gen 2 for home backup; the Anker SOLIX S2000 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
Are the Anker SOLIX C2000 Gen 2 and Anker SOLIX S2000 from the same lineup?: Yes — same manufacturer, so warranty terms, app, accessory ecosystem, and expansion batteries are usually shared. That narrows the decision to the hardware differences above rather than to which company you want to buy into.
