Every product in our store carries the official datasheet. Here is how to extract the five numbers that matter.
1. Rated Output Power (W/VA)
The continuous AC power the inverter delivers. Your simultaneous household load must stay below this.
2. Max PV Input Power
How much panel wattage you may connect — usually 1.2–1.5× the output rating. Oversizing panels within this limit improves morning/evening output.
3. MPPT Voltage Range
Your panel string voltage must live inside this window across temperature extremes. Wider is more forgiving.
4. Battery Voltage and Charge Current
48V systems dominate. A 60–120A charge rating determines how fast solar can refill your bank.
5. Efficiency and Switchover Time
Look for ≥93% peak efficiency (hybrid) or ≥97% (on-grid) and a ≤20ms transfer time for seamless backup.
