220Vac 50Hz Intelligent Solar UPS PV UPS 3000Va / 2400W Inbuilt 33Amp PV Charger
Model: Solar PV Online UPS Bright Star Series 1K-3Kva ( 1ph in / 1ph out )
Absolute advantages
1: No affexted by nation power regulartion policy
2: Ouput voltage is stable. Zero transfer time between line mode and battery mode.
3: Battery works in normal situation, not frequently discharged and the life time is extended max long.
4: UPS works even in very low AC voltage when PV is also in picture together sharing the load.
Working Principle
1: PV Charges DC CAP with its maximum power and DC-DC booster work with +/- 390Vdc, if load power
is bigger than PV power, the DC CAP voltage will drop and DC-DC booster output voltage will decrease
too, AC-DC booster works with +/-360Vdc, thus it will share the load power automatically between PV
AC. So the DC CAP voltage will reach to a stable value. Battery SCR Q1 stops if line voltage is normal
2: If PV power is bigger than load power, MPPT charger autoatically charges the battery. MPPT charger
works in fload voltage mode, MPPT mode if battery voltage and DC CAP Voltage are high.
3: If AC loose, stop AC-DC booster, switch on batter SCR Q1, make battery and PV works together to
power for the load.
4: If both PV and AC not there, battery works to power the load as the last option.
