Areswatt, a company specializing in smart solar energy solutions, was present at Intersolar South America 2025 with a full line of new products aimed at both residential and commercial consumers.
2,5 kW Microinverters with 4 MPPTs: High Power and Efficiency
Among the main highlights was the 2,5 kW microinverter, which was characterized by its power higher than the national market average, dominated by models of up to 2,25 kW, and for having four independent MPPTs (Maximum Power Point Tracking), with a wide voltage range (16V–60V).
According to the company, the microinverter already has AFCI and INMETRO certifications, in addition to ensuring optimized performance even in partial shade conditions, as well as greater efficiency in adverse climates.
The model presented has a maximum input current of 20A per MPPT, fully complying with Brazilian standards and eliminating the need for additional rapid shutdown devices. Other features include:
- Efficiency of up to 96,5%;
- Compatibility with latest generation photovoltaic modules;
- IP67 weather protection and multiple AC/DC protections;
- Smart monitoring via Wi-Fi, Bluetooth and Ares Cloud app;
- “Go by ONE CLICK” feature, which facilitated instant activation of photovoltaic energy
With a power density greater than 1kW/L, the microinverter was ideal for projects that required performance in a compact space.
Compact Balcony Storage: Affordable Solar Power in Urban Areas
With urban consumers in mind, Areswatt also introduced its new storage system for balconies. Compact, safe, and easy to install, the device was designed to operate at voltages below 60V, maximizing safety and allowing for plug-and-play installation directly into standard outlets.
With a storage capacity of 2048 Wh and output power of up to 1000 W, the system could receive photovoltaic input of up to 1200 W and was expandable to up to 8 kWh of battery and 4,8 kW of PV input, ideal for those looking for energy autonomy even in apartments.
Other features included:
- IP65 protection rating, allowing outdoor installation;
- Battery heating function for low temperature operation;
- Stackable and modular design;
- Remote monitoring via app with Wi-Fi and Bluetooth support
Compared to traditional residential storage systems, the balcony system offered significant cost-effectiveness advantages.
It allowed users to start with the microinverter and solar panels, and only later add the battery as needed. This modularity facilitated investment in stages, unlike traditional systems that required a full investment at once.
Furthermore, the DIY (do it yourself) project, with direct connection to the socket and without the need for extensive cabling, made it the ideal solution for consumers looking for practicality and savings.
Portable and off-grid solutions for different user profiles
A Areswatt also presented its portable stations and off-grid solutions, focusing on portability, reliability and high power density.
The devices offer high power in a small size, making them ideal for emergency use, travel, or remote locations without access to the electrical grid.
- 03 nominal power supplies (800W, 1200W and 1800W)
- Power capacity up to 1024 Wh
- Possibility of charging with solar panels or connection to the grid
- LiFEPO4 battery
- More than 3500 cycles
Tailor-made energy for the commercial and industrial sector
Focused on expanding its range of energy solutions for the commercial and industrial markets, the company opted for a standardized storage system, but with the flexibility to customize it to meet different consumption demands.
The product is All-in-one and that with it it is possible to connect others of the same in parallel to reach the nominal power required for the project, characterized by its size of 1,4m x 1,35m x 2,35m.
"Our C&I storage product was most likely to be a standard product. The standard version was 261 kWh. We offer this solution ranging from 130 to 261 kWh, fully customizable," the company confirmed.
"The user could also choose additional integrated MPPT modules for photovoltaic capabilities. The effectiveness of this product was obvious: all the inverter, MPPT, and battery modules were intelligently integrated into a single box, measuring approximately 2 x 1 meter. All the user had to do was connect the AC output to their power box and leave the rest," he concluded.
