Sunbridge 3000 Off-Grid Solar Inverter

The Sunbridge 3000 Off-Grid Inverter provides a better solution for the off-grid based solar panel systems. The power inverter has a working capacity of 3000VA (watts). The input voltage required for the efficient working is 230 VAC. The frequency range of Sunbridge 3000 Off-Grid Solar inverter is 50/60 Hz with auto sensing. The selectable range of volts to operate smoothly is;

  • For desktop computers—170-280 VAC
  • For standard home appliance—90-280 VAC

The output regulation is covered with a voltage range of 230 VAC ± 5%. On the other hand, the surge power ratio is greater than 6000 VA. The transfer time for the personal computers is 10 ms and for the standard home appliance usage, it is up to 20 ms. The solar inverter uses the pure sine wave as the output waveform that ensures fully efficient transfer.

Battery Connectivity

The battery voltage required for the operativity is 24 VDC. The floating charge voltage of the solar inverter for the battery is 27 VDC. The solar inverter is integrated with the protection feature to prevent the damage from the over-charging—exceeding at the voltage of 33 VDC.


The solar charger used in the sunbridge 3000 off-grid solar inverter consists of MPPT. The maximum voltage of the PV array open circuit is up to 102 VDC. The full given out potential of the PV array power is up to 1000 Watts. On the other hand, the dc to ac inverter has MPP range) operating voltage) of 30~80 VDC. The maximum solar AC charge current is up to 40 amperes. The power inverter has a charge current potential of 25 amperes. The maximum charge current from the Ac charger is up to 60 Amperes.

Ease in Installation

The Sunbridge 3000 off grid solar inverter has the sleekest design that allows easy installation—the dimensions of the voltage inverter are 100 X 285 X 334 mm (D X W X H). The dc inverter is light to carry, only weighing 14 lbs. (6.5 kgs). The user can set the start up with a communication interface; USB/RS232.


The off-grid inverter is uses selectable high-power current for better performance. It is likewise compatible with mains voltage or generator power. As one of the best solar inverter 2021, the model has auto restart while AC gets recovered. On the other hand, the smart battery charger is designed for optimized battery performance—while being integrated with the cold start function to kick in even if the solar inverter is left in storage for much time.

Note: Maxpower brings the optimal, durable and high performing solar inverters for residential & commercial solar panel systems. Moreover, product listings are not limited by them, we likewise offer;

Suitable Environment

For storage of the PV inverter, the temperature range is -15° to 50° C. The Sunbridge 3000 off-grid power inverter can tolerates the humidity range from 5% to 95% (non-condensing). The optimum temperature for efficient operativity is -10° to 55° C.
