What you need to know about 1500-volt inverters. By Chris Crowell February 18, 2016. Seems like just yesterday that large-scale PV systems moved to 1,000 Vdc in the United States, but another sea change to the 1,500-volt system is imminent.

Proof that 1500VDC systems are the new standards for the PV industry is Sungrow’s introduction of a 1500V string inverter. This is the world’s first string inverter with the higher DC input voltage range, but as with other firsts, others.
I provide an overview of the pros and cons of different design approaches to fielding PV power systems with 1,500-volt, 3-phase string inverters.
In this guide, we will break down the components of solar inverter specifications for home and commercial sectors and discuss them in simple terms. 1. Input Specifications. The input specifications of an inverter concern the DC power originating from the solar panels and how effectively the inverter can handle it.
Typically the maximum voltage of the system is either 600V or 1000V (or 1500V in utility-scale systems). Typically residential systems will be 600V and in the U.S. the NEC sets this as the legal limit for dwellings with 1-2 families. See our article on calculating solar PV string size for further information.

6 FAQs about [What does 1500v photovoltaic inverter mean]
Do you need inverters in a solar PV system?
That is why in a normal household, we need to install inverters in a solar PV system to convert the DC into AC. It can then be connected to the existing AC board of the house so it can either be used by the household or exported into the electricity grid. Some off-grid solar PV systems can be set up to only supply and use DC.
Is a solar inverter a converter?
A solar inverter is really a converter, though the rules of physics say otherwise. A solar power inverter converts or inverts the direct current (DC) energy produced by a solar panel into Alternate Current (AC.) Most homes use AC rather than DC energy. DC energy is not safe to use in homes.
Is a 1500 volt Solar System coming?
Regardless, the 1,500-volt system is coming. Now, when 1,000-volt panels came to the U.S., BOS components lagged behind for a few years, but this time around, developers looking to install a 1,500-volt large-scale system shouldn’t worry as much about component supply issues.
What are the different types of solar power inverters?
There are four main types of solar power inverters: Also known as a central inverter. Smaller solar arrays may use a standard string inverter. When they do, a string of solar panels forms a circuit where DC energy flows from each panel into a wiring harness that connects them all to a single inverter.
Why is a 1500 volt inverter so small?
Part of this response is due to the NEC 2017 draft, in which 1,500-volt inverters are expected to be limited to ground-mount only, which does shrink the effective market size of 1,500-volt inverters. Why 1,500 volts? It boils down to longer strings and fewer components.
Is a 1500 volt inverter overstated?
Some inverter/optimizer sources noted that the 1,500-volt value might be slightly overstated, too. Some inverter products on the market work on a fixed string voltage where string lengths are based on power and not voltage.
