- 📈 Higher yield across wider hours: 3 MPPTs and broad PV windows capture more energy in mornings/evenings and during hot midday conditions.
- 🧩 Scalable growth: parallel up to 10 units to expand capacity or add redundancy as projects grow.
🏭 Application Scenarios
- 🏠 Homes & villas needing true-UPS behavior with reliable battery storage.
- 🏢 Shops, offices, workshops & warehouses with mixed sources (PV + grid + generator).
- 🏭 Light industrial/agri and off-grid systems across Saudi Arabia, UAE, Oman, Qatar, Bahrain, Kuwait, and Yemen.
❓ FAQs
Does it support parallel operation?
🔸 Yes—up to 10 units on-grid or off-grid to increase capacity and provide operational redundancy.
What are the PV input specs per MPPT?
🔸 Three MPPTs (2/1/1) with usable/Isc currents of 25/34 A, 15/17 A, and 15/17 A; MPPT range 120–500 Vdc; full-power 230–500 Vdc.
What’s the UPS transfer time and waveform?
🔸 < 20 ms with a pure-sine output and THDV < 3%—ideal for sensitive electronics and IT loads.
Can I connect a generator or use AC-Coupling?
🔸 Absolutely—use the dedicated port for auto-start/exercise/boost generator control, Smart-Load, or AC-Coupling as required.
