As of August 2026, Latin America and the Caribbean had approximately 3.4 GW of BESS systems in operation, more than double the 1.68 GW identified in 2025, according to the Latin American and Caribbean Energy Organization (OLACDE). Chile accounts for nearly two-thirds of the total.
In line with this scenario, GoodWe presented a new architecture for the commercial and industrial (C&I) segment on October 14th, comprised of the ETR line of hybrid inverters from 50 to 125 kW and the BAT-C battery systems of 208.9 and 261.2 kWh . This initiative aims to expand the scale of projects and, at the same time, allow companies to incorporate energy storage gradually.
And the movement won't end there. Andrés Azula , GoodWe 's Solutions Manager for South America—excluding Brazil—announced in an interview with Energía Estratégica that, before the end of 2026, the company will add two more generations of hybrid inverters for the residential and C&I segments.
Energy storage already accounts for approximately 60% of GoodWe's sales in South America , and the company aims to increase its share to nearly 80% of revenue. Furthermore, it is currently developing projects with ETR and BAT-C in Colombia, Chile, and Argentina , ranging from around 500 kW to 2 MW of power, with some projects reaching 4 MW dedicated solely to storage .
A progressive entry into storage
One of ETR's key differentiators is its Battery-Ready architecture. A company can start with photovoltaic generation alone and add batteries later without replacing the inverter , thus reducing the initial investment.
According to Azula, the configuration responds to a recurring situation among industrial clients: there is interest in storage, but the investment cannot always be made from the beginning.
“Many times they want to install their photovoltaic solar plant and generate savings initially, but then they realize the different applications of storage, such as peak shaving or load shifting . They may initially not have the investment capacity for a system with BESS,” he explained.
BAT-C, on the other hand, uses LFP technology and comes in nominal capacities of 208.9 and 261.2 kWh . The battery incorporates liquid cooling, 314 Ah cells, and a declared lifespan of up to 10,000 cycles under the conditions specified by the manufacturer.
But one of the central points of the new proposal is the scale that the whole can reach.
“We can have a system with a 125 kW inverter and a 261 kWh battery, but we can also have 15 units and four batteries per inverter. That gives us more than one MWh per inverter, and we can exceed 15 MWh in a plant ,” he explained.
In C&I, storage is starting to be used not only as backup but also to increase self-consumption, reduce peak demand and shift solar energy produced during the day to nighttime hours .
“There are companies that operate 24 hours a day. That solar generation that during the day could be lost due to clipping or sent to the grid, they can store and deliver at night to their loads,” the executive noted.
Progress, however, remains contingent on the economic conditions of each market. Azula pointed to access to financing as one of the difficulties in Argentina and regulation as one of the outstanding challenges in Peru, while identifying Chile as one of the markets with the most favorable conditions.

A case that is already in its second stage
GoodWe already has regional experience that allows us to observe this logic in operation.
In Cerro Guido, near Torres del Paine, in Chilean Patagonia , the company participated in a project to supply a completely off-grid hotel using a microgrid that combines photovoltaics, batteries and diesel generation.
The first phase added 100 kW of power and 200 kWh of storage . Before the installation, the hotel relied on a diesel generator 24 hours a day.
Following the initial experience, the owner decided to move forward with an expansion that will bring the system to 200 kW of power and 400 kWh of storage .
The case also serves as an example of the phased growth model that GoodWe intends to deepen with its new architecture: starting with a certain capacity and expanding the system according to the evolution of demand.
The company is also monitoring two photovoltaic installations of more than 1 MW in Argentina , a ceramic brick factory in Resistencia, Chaco, and a cassava production plant in Misiones, whose owners are already evaluating incorporating storage into existing projects.
Next up: ES G3 and ET G3
The presentation of ETR and BAT-C will not close GoodWe's release schedule for 2026.
Azula told Energía Estratégica that during the fourth quarter the company will move forward with ES G3 , its new generation of residential hybrid inverters.
Among its new features will be direct coupling with generators . It will initially be available in select South American countries while the company completes certification processes and meets protection requirements for other markets.
ET G3 will also arrive, aimed at everything from small C&I applications to medium-scale projects, with power outputs from 20 to 50 kW .
The new generation will also incorporate direct coupling with diesel generators and improvements in integration, efficiency, and performance. GoodWe anticipates general availability for the South American market during the last quarter of the year.
In addition to the equipment upgrade , CEMS Plus 2.0 , GoodWe's new management and monitoring platform, began operating in August, replacing the previous version of CEMS and also integrating SolarGo functions.
According to the Goodwe representative, the tool centralizes monitoring and commissioning in a single environment, incorporates greater data processing capacity, and allows for remote tasks that previously required on-site intervention. This enables installers and distributors to manage plants located in different parts of the region from their offices.
Thus, the company seeks to cover different levels of a market that is beginning to demand increasingly flexible solutions: from companies that want to prepare today for a future incorporation of batteries to industries that are already evaluating storage systems of several megawatts.
