Bottom Line

Mega 2 combines 2,048 Wh with 2,500 W continuous output and supports high solar input; its 48.5 lb base unit is intended for a less-mobile setup.

Strengths

Practical advantages

  • High solar inputThe 2,100 W maximum is paired with an 18–140 V, 15 A MPPT range inside a 12–148 V port window.
  • Combined-input capabilityConcurrent AC plus solar input is stated as 3,700 W: 1,600 W AC and 2,100 W solar.

Tradeoffs

Supported limitations

  • Full-charge claim is mode-specificThe approximately 0.6 h claim applies to 1,600 W AC plus 2,100 W solar; AC-only and solar-only times are not published.
  • Weight and UPS limitThe 48.5 lb base weight excludes B2 batteries; UPS is stated as under 20 ms at a 2,500 W rating, not as a measured transfer time.

Evidence gaps

What remains unknown

  • Combined-charge conditionsThe approximately 0.6 h claim does not state its charge endpoint or full input conditions.
