C&I Applications Driving the Adoption of Solar + Battery Solutions in Brazil

Energy storage in Brazil is still at an early stage, but commercial and industrial (C&I) applications are emerging as the most promising. While the residential segment faces economic and regulatory barriers that still prevent “revenue stacking,” for C&I the motivation goes far beyond cutting electricity bills: operational continuity is a strategic asset.

Why will the C&I sector lead battery adoption?

Imagine a factory standing still for hours due to a grid failure — the cost can easily surpass the investment in an efficient backup system. In this scenario, hybrid inverters with high-voltage (HV) batteries provide competitive advantages: instant response, voltage stability, protection against micro-interruptions, and seamless integration with sensitive equipment such as data centers, plastic injection molding machines, CNC systems, and laser cutting equipment.

Moreover, hybrid systems are the ultimate solution for “zero grid” installations, a growing reality where energy injection into the grid is not allowed. Instead of wasting surplus PV generation, hybrid inverters store this energy in batteries for later use, maximizing self-consumption.

According to Greener (May 2025), a 50 kW commercial PV system can pay for itself in less than two years. Even if adding batteries extends the payback period, the return on investment remains extremely competitive — especially when compared to the cost of unplanned production downtime.

Solis: leading the new era of energy storage

The outlook is becoming even more favorable with Brazil’s ongoing power sector reform and ANEEL’s upcoming regulation, expected to allow compensation for storage agents. This will open space for new business models and accelerate the market.

Solis, a global leader in solar inverters, is ready to guide the C&I market into this new era.

📌 At Intersolar South America 2025 (August 26–28, São Paulo), Solis will showcase advanced energy storage and “Zero Grid” solutions designed for C&I applications. The highlight will be the exclusive pre-launch of the new 125 kW hybrid inverter — a robust, intelligent solution built for the most demanding industrial needs.
