The Sunbridge 8000 Off-Grid Solar Inverter is finely integrated for larger capacity load and powerful operation—while providing a rated power range of 7200 watts. The voltage input of the solar inverter is 230 VAC. The PV inverter is featured with adjustable voltage range as;

  • 170 – 280 VAC for personal computers
  • 90 – 280 VAC for standard home appliances

Working Efficiency

The Sunbridge PV8000 is a self-sustained PV inverter model integrated as the best solar inverter 2021. The frequency range adhered as input is 50/60 Hz—there is no need to configure the frequency manually as the solar inverter model features automatic sensing. On the other hand, the AC voltage regulator operates at the battery mode while regulating at 230 VAC ± 5%.

  • Surge Power: The surge power ratio by the Sunbridge PV8000 is around 16K VA.
  • Conversion Efficiency: The sustained efficiency reach of DC to AC power conversion is from 90% – 93%.
  • Transfer Time: for the personal computers, the transfer time delivered is up to 15 ms—likewise, it can reach up to 20 ms for standard home appliances.
  • Waveform: The pure sine wave is used as the output waveform that ensures much compact efficiency than the competing solar inverters.


The range of battery voltage used in the DC to AC inverter is up to 48 VDC. On a side note, the floating charge voltage has the highest ratio of 54 VDC.

Overcharge Protection

Most of the cases are noted to be critical, causing massive losses, because of battery to circuit burning—these happen as the overflow of charge through the circuit. In the modern solar technology, it can be inhibited by the help of an overcharge protection feature. The Sunbridge PV8000 restricts the charge flow over 68 VDC, thus ensuring safe circuits.

Solar & AC Charger Operation

The type of solar charge used in the Sunbridge Solar Inverter is MPPT. The maximum open-circuit voltage by the PV array is 500 VDC. Also, the maximum PV array power generated by the DC inverter is 8k Watts (4000 W X 2). The operating voltage range of the MPPT module is 90 ~ 450 VDC. The maximum solar charge current, AC charge current, and plain charge current delivered by the AC inverter are 80 amperes, respectively.


As the solar panel inverter is heavier than the ordinary inverters for household use—the net weight is 41 lbs. The structure of the model is compact, ensuring durability and extended life expectancy. It has enabled a USB/RS232 port for the communication interface.

Environment Suitability

The humidity tolerance of the Sunbridge PV8000 solar inverter is 5% to 95%. Likewise, it can efficiently operate in a temperature range of -10° to 50°C.  For the storage, the range moves from -15° to 60° C.

Frequently Asked Questions

How Off-grid solar inverters work?

The sunlight is captured and converted into DC energy by the PV plates. This DC energy is changed into AC. Here, as the on-grid solar panel feeds the excess energy to the grid, the off-grid does not! No connection to the grid station, so, here the question comes, “where does the excess energy go?” The short answer is “it is fed to the battery packs, to use later”

How do I know if my solar inverter is working?

The simple but viable way is to check the display screen of the solar inverter. The commended models like;

Have green flashing lights that make sure they are working properly. Also, these models are able to notify the user if there is some connection breakage or interruption in conversion.
