Schneider Electric Solar Conext XW+ 6848 Battery Inverter Review

When it comes to the newer industry of solar power, you can look to the long-established French company Schneider Electric. Their solar business, Schneider Electric Solar, is moving Schneider Electric into its second century with its latest solar inverter in the form of the Conext™ XW+6848 Battery Inverter.

Where’s Solar Energy headed?

According to Wood Mackenzie Power & Renewables/Solar Energy Industries Association (SEIA), there were more than two million new solar photovoltaic (PV) installations in the U.S. in the first three months of 2019. The SEIA reported that the U.S. installed 2.7 GW of PV with Wood MacKenzie forecasting 25% growth in 2019 over 2018. It expects over 13 GWdc in installations in 2019.

In addition, DNV GL predicted PV capacity will increase to 19,000 Gw in 2050, representing nearly half of all installed electricity globally.

Why the increase?

Efficiency increases from the crystalline structure of panel materials. The less expensive components are driving the growth in PV installations. The cost per kilogram of polysilicon dropped from $17.50 in Q1 of 2018 to $9.30 at the end of Q3. The cost per watt for multi-wafer components also decreased: over the same period, going from $0.13 to $0.06 in this same time period.

Who’s the brains of the outfit?

In the world of solar energy, it’s the inverter.

Beside its main role in converting DC power from the solar array into usable AC power, inverters’ jobs are expanding. They’re now enabling monitoring so you and your customers can see how their particular system is performing.

They can provide you with diagnostics that allow for the identification and repair of system problems, and they’re improving grid stability and efficiency.

Aside from the various types of inverters—string, central, and microinverters—there’s also the battery inverter.

While string inverters, central inverters, and microinverters all have their fans based on price, performance, and maintenance, they do come with some cons that may make the battery inverter a more interesting choice. Let’s take a look:

String inverters

While the least expensive of the inverters, if the string inverter breaks down, the whole solar array will be inoperable, and there will be a significant loss of electricity production. In addition, its scalability for future expansions is limited. They also don’t provide panel-level monitoring.

Central inverters

The downsides of central inverters are their size and the noise generated. However, a more main point is that if one part of an array fails, the whole system can potentially fail.


Microinverters have higher pricing and higher costs to operate per watt. There’s the need to have as many inverters on a roof as there are panels with the need for increased maintenance.They may have issues when subjected to extreme heat.

Battery inverters

A battery inverter can be used in multiple installation types, whether it’s grid-interactive or off-grid. It works with standard residential and commercial solar and backup applications and configurations, and can allow for grid and generator integration.

It’s also scalable up 76.5kW, making it ideal for large application power handling or even when a smaller installation wants to expand.

The battery inverter has built-in functions that allow for monitoring and troubleshooting. This includes fast configuration and system commissioning.

Schneider Electric Solar provides a battery inverter that adapts to the next-generation grid requirements.

Future-ready inverter designed to adapt to next-generation grid requirements

The Schneider Electric Solar Conext™XW+6848 Battery Inverter is an adaptable, modular single-phase and three-phase hybrid battery inverter with grid-tie functionality, handling anywhere from 7.0 kW to 102 kW. It enables solar prioritization, load shifting, peak shaving, and also assists small generators with heavy loads.

Supports the charging of lithium-ion battery packs

This Schneider Electric Solar Battery Inverter has benefits over other inverters in that it stores its power in batteries. This may be the same with other battery inverters, but while it does store its power in batteries, the Conext™XW+6848 supports the charging of lithium-ion battery packs, making it one of the few inverters on the market to do so.

This Schneider Electric Solar is a self-contained unit that converts DC energy into AC energy to the utility grid, drawing upon energy as it’s needed for energy stabilization.

A scalable battery inverter

Schneider Electric Solar Conext™XW+6848 Battery Inverter is highly scalable over its competitors. A single unit scales to clusters up to 76.5 kW, scaling if and when a solar system’s needs increase. Whether it’s a commercial installation or a residential system whose owner wants to add to the current system, this hybrid battery inverter is more than capable of doing the job.

An adaptable battery converter

The Conext™XW+6848 Battery Inverter is highly adaptable in its performance, coming with a range of product applications. It’s ideal for residential grid-tie solar with backup power, off-grid solar and grid interactive, backup power, self-consumption, electrification of communities, and commercial uses, making it an ideal source for a wide range of uses.
