Technical FAQ & Sizing Guide
How do I choose between a Portable Power Station and Whole-Home Backup?
Portable stations (RIVER & DELTA series, 256Wh–4kWh) offer plug-and-play power for RVs, camping, and room essentials. Whole-home systems (DELTA Pro Ultra, TITAN 5000, Smart Home Panel 3) scale from 5kWh to 30kWh+ with 240V split-phase output for full household circuits.
How long do LiFePO4 battery cells last?
Our LFP (Lithium Iron Phosphate) battery packs are rated for 3,000 to 4,000+ full cycles before reaching 80% capacity—delivering roughly 10 years of dependable daily use.
Can I charge a power station while running appliances?
Yes. Pass-through charging and dual AC + solar input allow you to power connected appliances while simultaneously recharging from rooftop or portable solar panels.
Is shipping included on heavy battery and solar orders?
Yes—every portable power station, extra battery module, and solar panel order includes free insured delivery directly to your address.
