Which Inverter Should You Choose?

1. Fortress Power Envy 8K

✅ Best for:

• Smaller homes or businesses (1,500–2,500 sq ft).
• Basic backup needs (essential appliances: fridge, lights, internet).
• Budget-conscious buyers who still want reliability.

❌ Limitations:

• Lower surge capacity than 10K/12KW.
• Only 2 MPPT trackers (less solar flexibility).

2. Fortress Power Envy 10K

✅ Best for:

• Medium-sized homes or businesses (2,500–3,500 sq ft).
• Higher power demand (essential and major appliances: kitchen stoves, AC units).
• Future expansion (15kW PV input).

❌ Limitations:

• Still only 2 MPPT trackers (less optimal for complex solar setups).

3. Fortress Power Envy True 12KW

✅Best for:

• Large homes & light commercial or industrial use (3,500+ sq ft).
• Heavy-duty loads (heavy appliances: multiple ACs, EV charging, water heater).
• Complete solar setups (3 MPPT trackers for max solar efficiency).
• Whole-home backup (200A passthrough for no compromises).

❌ Limitations:

• Most expensive option.

All models support:

✔ Lithium & lead-acid batteries

✔ AC Voltage (120/240 single split-phase, 120/208 three-phase, 127/220 three phase)

✔ Hybrid operation (solar + grid + generator)

✔ Parallel expansion (up to 10 units)

✔ Smart monitoring (Wi-Fi/App control)
