Pros & Cons
What We Like
- 9,000W surge rating handles motor startup on well pumps and compressors
- Built-in 80A charger and automatic transfer switch
- 10ms transfer time — faster than most competitors
- Excellent value at ~$200/kW for an inverter-charger
- Programmable charge profiles for different battery types
Watch Out For
- 24V input requires two 12V batteries in series
- 2-year warranty is shorter than Victron's 5-year
- No Bluetooth or Wi-Fi — monitoring requires physical access
- Less established brand compared to Victron or Magnum
- Fan runs loud under sustained high loads
