RENAC POWER makes its debut at Intersolar South America, seizing new opportunities for growth in the Brazilian market through commercial and industrial energy storage solutions

From 25 to 27 August, Intersolar South America, a highly influential new energy exhibition in Latin America, took place as scheduled in São Paulo, Brazil. Renac Power showcased its core commercial and industrial energy storage solutions, as well as its range of residential photovoltaic and energy storage products.

The stand attracted a steady stream of visitors throughout the event, with local installers and distributors expressing strong interest in collaborating on the energy storage product range. Through face-to-face discussions, we gained a tangible sense of the momentum in Brazil’s energy storage sector, with extensive exchanges taking place on practical issues such as product implementation and project execution.

Market Insight: The Three Practical Considerations for Commercial and Industrial Energy Storage in Brazil

The decision by Brazilian commercial and industrial enterprises to adopt energy storage essentially boils down to three tangible business considerations.

The first is the electricity cost calculation: local evening peak-hour electricity prices can reach 3–5 times the normal rate; coupled with hefty demand-side penalties, many enterprises use energy storage to shave peaks and fill valleys, thereby directly reducing their electricity bills.

The second is the production reliability calculation: grid stability is insufficient in some regions, with some states experiencing over 190 hours of power cuts per year; energy storage has become a reliable safeguard for factories to mitigate the risks of production stoppages caused by power cuts.

The third calculation concerns fuel costs: as the cost of diesel-generated electricity remains at US$0.35–0.45 per kWh, an integrated solar-storage-diesel solution can tangibly help businesses reduce their operational, maintenance and energy consumption costs.

Core Solution: Rena5000, Adapted for Diverse Retrofit Scenarios in Brazil

At this exhibition, the Rena5000 commercial and industrial energy storage solution was the flagship product attracting the most attention. This solution is adaptable to a wide range of scenarios; it supports both the construction of new commercial and industrial solar-storage projects and the retrofitting of Brazil’s vast existing portfolio of solar power stations with energy storage.

The product features a highly integrated, all-in-one design, which reduces the complexity of installation for local teams and lowers overall delivery costs. Based on an AC-coupled architecture, it allows energy storage equipment to be directly retrofitted to existing solar power stations, enabling the efficient modernisation of existing projects.

The coordinated control of PV, energy storage and diesel generators enables automatic grid-connected/off-grid switching within 20 milliseconds, supports 100% off-grid unbalanced loads, and features a transformerless design. This eliminates the need for diesel generators as the primary power source, simultaneously addressing the dual requirements of cost reduction and efficiency improvement whilst ensuring a reliable power supply.

Residential and Commercial Energy Storage: Tailored to Local Grid Conditions in Brazil

Renac Power’s residential PV-storage range features the N1 LV single-phase low-voltage inverter, the N2 split-phase hybrid inverter and the Turbo L2 low-voltage battery.

Both the N1 LV single-phase low-voltage inverter and the N2 split-phase hybrid inverter can be used in conjunction with the Turbo L2 low-voltage battery. They support a maximum PV string input of 20A, achieve grid-connected to off-grid switching in 10 ms, and are compatible with diesel generators and smart loads; They support AC coupling for flexible future expansion; with a maximum charge/discharge current of 190A, they support 2x PV over-provisioning, feature a 10-second 2x overload capacity, and include AFCI functionality. The core difference between the two lies in their positioning for different grid conditions in Brazil:

Localised Team: Bridging the ‘last mile’ to market implementation

Equipment can be shipped across the ocean, but there are no shortcuts when it comes to localised services.

Throughout the exhibition, Renac Power’s local Brazilian team was on hand to provide support, offering technical consultations in Portuguese, project solution design and business negotiation facilitation. From initial site surveys and the delivery of bespoke solutions to subsequent installation, commissioning and online cloud-based operation and maintenance, they have established a comprehensive, full-cycle local service ecosystem. For Renac Power, expanding into the Brazilian market is not merely about securing individual orders; the company aims to cultivate a network of long-term partners.

Market-oriented reforms in Brazil’s electricity sector are progressing steadily, and the growth potential of consumer-side energy storage is gradually becoming apparent. However, market implementation also faces multiple practical challenges, including a complex grid infrastructure, evolving policies and the practicalities of project execution.

The conclusion of Intersolar marks merely the beginning. Moving forward, Renac Power will continue to deepen its presence in Brazil. Leveraging its mature photovoltaic-storage products and localised service capabilities, the company will work hand in hand with its channel partners to jointly explore opportunities in the South American energy storage market, helping local commercial, industrial and residential customers achieve a more economical and reliable supply of renewable energy.
