Anker’s SOLIX line stretches from the compact, towable F2000 up to the whole-home-ready F3800 Plus. Each model targets a different balance of capacity, power delivery, solar recharge speed, and expandability — and choosing the right one depends on whether you need a weekend RV power source, a resilient household backup, or a scalable whole-home system. Below is a practical, vendor-spec driven comparison and a recommendation guide to help you pick.
Quick model snapshots
Anker SOLIX F3800 Plus — Built around whole-home backup and expandability, the F3800 Plus ships as a 3,840 Wh LFP unit that can be stacked with up to six expansion batteries (3.84 kWh each) for a total system capacity up to ~53.8 kWh. It supports dual-voltage 120V/240V output with up to 6,000 W AC (with generator bypass options) and high solar input (up to 3,200 W), and it’s designed to integrate with transfer switches and home power panels. It also carries a 5-year warranty and an LFP battery rated for long life.
Anker SOLIX F3000 — The mid-tier F3000 bridges portable power and heavier home backup. It uses LFP chemistry in a 3,072 Wh pack, delivers up to 3,600 W continuous AC, and accepts up to 2,400 W of solar input for very fast recharge. The F3000 emphasizes rapid solar recharge (<2 hours in ideal sun) and modular pairing (two units can be used for 240 V loads), making it well suited for households that want serious capability without whole-home infrastructure changes.
Anker SOLIX F2000 — The most portable option here, the F2000 is a 2,048 Wh LiFePO4 unit with 2,400 W AC output and 1,000 W maximum solar input. It’s wheel-and-handle portable, recharges quickly (Anker advertises 0→80% in ~1.4 hours under ideal conditions), supports expansion to 4,096 Wh with an add-on battery, and is positioned at a lower price point for RV, tailgate and light backup use.

How to choose — practical guidance
- You want whole-home backup and future scalability: choose the F3800 Plus. Its 120/240 V dual-voltage capability, generator bypass, high solar input and large expansion ceiling make it the right platform for multi-day outages or replacing a home generator.
- You want high-power backup without a full home retrofit: choose the F3000. It delivers 3.6 kW continuous power, very fast solar recharge, and can be paired for 240 V loads — a smart middle ground for most households.
- You need portability and lower cost for RVs / weekend use: choose the F2000. It’s lighter, towable, and still powerful enough (2.4 kW) to run most essentials and RV appliances, with expandability if needs grow.
A clear ladder
Anker SOLIX offers a clear ladder: F2000 for portable, budget-conscious users; F3000 for serious home backup with rapid solar recharge; and F3800 Plus for those who want a scalable, whole-home replacement with generator integration and very high solar input. Match the model to your outage profile (hours vs days), appliance power demands, and whether you plan to expand later — and you’ll get the most value from the SOLIX family.
