Showcased at the NeoSolar Booth at Intersolar 2022, SIGFI was developed to integrate government social projects such as the More Light for the Amazon Program. Among various advantages, the system reduces installation costs
NeoSolar, a leader in the Off Grid solar energy market, and HOPPECKE, a German multinational specialized in energy storage, jointly developed an optimized SIGFI (Isolated System with Intermittent Source) to serve locations without access to conventional electricity.
More economical, easy to transport and install with low maintenance costs, the system is the best solution to meet the needs and requirements of government energy access projects such as the Light for All Program and the More Light for the Amazon Program (MLA).
The technological development is credited to NeoSolar and HOPPECKE, which is also the integrator responsible for distributing and installing it in the benefitted locations. With extensive experience in bringing energy to areas without access to the electrical grid, HOPPECKE recently participated in projects that benefited thousands of families on Marajó Island and around Belo Monte — both in Pará.

Among various advantages, SIGFI differs from a conventional Off Grid system by incorporating solutions that maximize equipment lifespan and reduce costs at all stages, whether in installation or in the operation and maintenance phase of the system.
The solution will be presented at the NeoSolar booth during Intersolar South America, the leading fair in South America for the photovoltaic and thermosolar sectors. The event takes place from August 23 to 25 at Expo Center Norte in São Paulo (SP).
Advantages for Installation in Isolated Regions
Following ANEEL guidelines, SIGFI was designed to meet government energy access projects such as the Light for All Program and the More Light for the Amazon Program. Developed by NeoSolar and HOPPECKE, the entire technical engineering of the solution aimed to ensure a prolonged lifespan for the system — in addition to making installation, operation, and maintenance much easier, cheaper, and more efficient in remote areas of the country.
Designed for consumption of up to 60 kWh/month, SIGFI has the autonomy to operate for up to 2.5 days without sunlight and is compactly designed for simpler transportation and installations, as well as reducing the need for maintenance and featuring a data logger to record generation and consumption data.
Another differentiator is the lithium battery sun I power LFP 48-105 from HOPPECKE, which stores the energy and ensures the system’s long autonomy. With a lifespan of 6000 cycles (considering 80% DoD and 25°C), the device offers shorter recharge times and greater safety, ensured by an internal BMS with active balancing.
Thousands Benefited by Government Programs
In Brazil, there are still over 500,000 people without access to energy living in remote locations or isolated communities from the electrical grid, who will be served by these government programs in the coming years. SIGFI from NeoSolar/HOPPECKE represents a significant advance in providing electricity to these populations more effectively and cheaply.
“Every small detail of the project was studied and tested exhaustively. Therefore, it is the ideal solution for bringing solar energy to remote locations not connected to the electrical grid, fully optimized to maximize lifespan and minimize all costs,” emphasizes Pedro Pintão, co-founder of NeoSolar.
“In addition to being a solution that facilitates all logistics, one of our main concerns was to bring extreme reliability to SIGFI. Thus, we incorporated equipment from solid and established manufacturers in this market like Epever and HOPPECKE, ensuring a long lifespan for the system,” he adds.
“Today, with our partners, we are ready to carry out any SIGFI/MIGDI project in a turn-key regime,” comments Antonio No, General Director of HOPPECKE in Brazil. “Projects like the one we carried out on Marajó Island are fully aligned with HOPPECKE’s mission and values, which are to provide energy to people and thereby improve their lives.”
Composition of NeoSolar’s Off Grid System
SIGFI from NeoSolar/HOPPECKE is a complete set, featuring a high-strength aluminum truss structure and reinforced fiberglass-insulated polymer cabinets, containing an inverter-controller set calculated and defined by NeoSolar, which, in partnership with HOPPECKE, also detailed the product engineering and specified half-cell monocrystalline photovoltaic modules.
The system uses lithium batteries from HOPPECKE that have a performance far superior to conventional batteries, with a capacity of 5.04 kWh, sufficient for up to 2.5 days of autonomy without sunlight and a lifespan exceeding 6000 cycles, while also requiring no maintenance.
The inverter and charge controller are from Epever, the largest manufacturer of Off Grid solar energy solutions worldwide, with high reliability. The system and components have also undergone a tropicalization process to meet the most demanding field conditions such as high temperatures, humidity, salinity, and overloads.
All the main components of the system have been extensively tested and the electronics harmonized through testing and analysis. Tropicalized to fit the installation site conditions, SIGFI is a complete product, ready to meet the needs of the Brazilian market, within the requirements of the Amazon soil.
