Bi-directional inverters for solar

What is an optical storage and charging bi-directional inverter (BDI)?

To meet this need, Delta developed an optical storage and charging bi-directional inverter (BDI). This all-in-one solution integrates the conversion and control of AC and DC power for household electricity infrastructure, rooftop solar power, energy storage batteries, and EV charging.

Should I add a bidirectional inverter to my solar power system?

Adding a bidirectional inverter to your solar power system makes it more efficient, provides a higher safety standard, and gives more flexibility for charging options (which comes in handy when sunlight is scarce). But before we tackle those, let’s go through a typical solar plus storage setup to highlight the impact of bidirectional inverters.

Why do you need a bidirectional inverter?

This means your electricity is clean (no harmonics) and won’t cause trouble for your electronics. A bidirectional inverter also allows you to charge your battery via an outlet, which means you can charge your battery using both DC solar and AC outlets. This gives you an alternative way to charge your battery on the road when solar power is scarce.

How does a solar inverter work?

In a typical residential solar setup, electric power flows only in one direction. The process is straightforward: DC Solar power is (1) harvested, (2) stored in the battery, and (3) converted into usable AC power via an inverter. Now, what happens when we replace the inverter with a bidirectional inverter?

Can a battery storage system be connected to a solar inverter?

In installations with a unidirectional inverter – most of the existing installations – the battery storage system could be connected (as an option) on the AC side of the solar inverter. This installation is made easier, but then needs a second, bi-directional inverter for the charge/discharge capability of the battery energy storage system.

What is a Delta solar inverter?

Delta provides solar inverters and monitoring from 3 kW to 80 kW. Our inverters offer exciting and innovative features that make installation easier, and deliver the maximum efficiency over a much wider power range compared to transformerless inverters from competitors.
