Sunbridge 4000 Off-Grid Solar Inverter

The Sunbridge 4000 solar inverter has a capacity of up to 3000 watts. The off-grid technology keeps the system sustained without any need of excessive energy flow from the grid. Sunbridge power inverters ensure durability with a sleek structure. The input voltage from the PV inverter is up to 230 VAC. Here;

  • The selectable voltage range of dc to ac input is 170-280 V (for personal computers), and 90-280 V (for home appliances).
  • The frequency range of solar power inverter as input; 50/60 Hz.
  • The Sunbridge PV inverter is able to auto sense the preferred frequency with auto sensing feature enabled.

Working Efficiency of Sunbridge 4000 Off-Grid Solar Inverter

The solar panel inverter delivers a DC to AC conversion efficiency of up to 90 to 93%. Likewise, the AC voltage regulation in the battery mode delivered is 230 VAC ± 5%. The surge power as the output of the dc to ac inverter is up to 6K VA. The transfer time for the personal computers is 10 ms and for the home appliances it reaches up to 20 ms. The waveform for the output transfer is pure sine wave that ensures optimal efficiency.

Charger Capacity

The maximum voltage delivered by the PV array open circuit of the solar inverter 2021 is up to 500 VDC. As being one of the best solar inverter 2021, the maximum PV array power is up to 4000 watts. The operating voltage as of the MPP module range is from 120 ~ 450 VDC. Now, getting on to the current ratios—the maximum solar charge current, AC charge current and maximum plain charge current, is 100 Ampere respectively.

Battery Operativity

As the Sunbridge off-grid solar inverter totally makes sure that the power integration is independent—thus, the plain battery voltage is 24 VDC. On the side note, the floating charge voltage can reach up to 27 VDC.

Overcharging Protection in Solar Inverter

The overflow of charge in the batteries is widely reported to damage the battery heath—The solar inverter is integrated with over charging protection, this prevents the decline and any harm to the battery health. The Sunbridge off-grid inverter inhibits the charge flow over 33 VDC.

Frequently Asked Questions

Does solar inverter turn off at night?

The solar panels generate electricity only when the radiations fall on the surface—at night time or in rainy day, the production is interrupted. Thus, no DC power is provided to the batteries, therefore, there will be no need to convert the energy into AC, thus solar inverter are operated less at night time.

How do I choose a good solar inverter?

There are some factors that features in a good quality solar inverter. The sine wave technology is better. The capacity should be according to the load by the solar panels and battery. Here are some other efficient solar inverters;

What are the advantages of solar inverter?

The solar inverters are the core requirement of a proper solar panel system. The fundamentals of using a PV inverter is that they convert DC power (generated by PV plates) to AC power. The energy efficiency is subtly increased while restraining energy loss. The operations by the solar inverter are safe. Likewise, they monitor the output power flow and there is improvement in grid assistance capabilities.
