A residence in Indaiatuba, located in the interior of São Paulo, operated completely independently of the electricity grid for a week, demonstrating the effectiveness of a hybrid solar energy system.
The project with the hybrid solution, installed by Renew Energia, includes four 8,3 kW SolaX hybrid inverters, each connected to three 5,8 kWh batteries, totaling 12 units, and a photovoltaic system composed of 44 665 W modules from Canadian Solar.
The investment, with an estimated payback of approximately five years, allows the owner to work from home no power or internet interruptions, resulting in annual savings of over R$50.
Watch the video below to understand in detail how the project works with the hybrid solution.

Dear Sirs, I have no doubt in stating that the future of photovoltaic generation will be the hybrid system with batteries. The world has been researching innovations in this field day and night, not only to serve residential, commercial, industrial and other similar consumers, but also for the automotive sector. As always in this sector, China is the protagonist. It has been investing an astonishing amount of resources. We know that with the advent and rapid expansion of data centers, with the incorporation of AI and the famous cryptocurrencies, the demand and consumption of energy are growing at a rate that challenges the installed energy capacity and its growth. As a digression, meanwhile, our central government is committing a major contradiction in taxing the sector from 9,5% to 25% of imported solar modules. It's easy! As I have said: Brazil, a strange nation! Engineer, professor, master in electrical engineering sciences, designer in photovoltaic generation, energy efficiency and electric vehicle charging station also with solar carpot.
I set up a Hybrid system and the initial investment was this:
– Sumry On/off Grid Hybrid Inverter 6.2kw 48/220v With Wifi R$ 4.883,95
– 12 Canadian Solar Panels 555W Monocrystalline Half-cell – CS6W 555MS R$ 7.234,00
– 4 Freedom DF4100 12V 220Ah Stationary Battery R$ 5.200,00
– Fixed Support Structure for 12-Plate Solar Panel R$ 768,09
– String Box with Clamper and DC Solar Circuit Breakers Grounding Rods R$ 480,00
– Electrical cables, connectors R$ 780,00
I have an on-greedy and the environment is grateful, just because in terms of economy they continue to rob us and charge taxes on what we produce, use of the posts, etc. They turn your energy bill into a Koran! If you are going to invest, get an off-greedy (independent) one right away. Don't fall for the idea of connecting to the grid. Leave the connection only for emergencies. Being independent is the best!
I have a solar system with 6 panels, but it is connected to the grid and if I talk about electricity, there is no electricity in the house either. If I had to use a battery it would be 4 times more expensive than what I paid.
The average price of an inverter like this is 7 thousand, the solar panel is 700, and the battery bank is 10 thousand.
4 inverters = 28 thousand
44 plates = 30.8 thousand
12 Battery Bank = 120 thousand
TOTAL = 178.8 thousand.
With service and installation something around 230 thousand.
The text says that the annual savings are 50 thousand and the payback is 5 years, it can be deduced that the cost is something around 250 thousand.
This, given an annual saving of 50 thousand, estimates an average monthly consumption of 4 thousand reais, which cannot be met for 7 days with this system. Another point is, what is the point of having a system with autonomy for 7 days in Brazil?
I have a hybrid solution in Salto, and the customer opted for Victron + Fronius: 10kVA with two 5kVA Quattros making the microgrid for the Fronius Primo 8.2, and 4 5kWh Dyness batteries, it works very well both in the smart grid function or just as an emergency backup.
But it's certainly not an investment for everyone. In 2021, the client invested more than R$200.
DOES SOLAX X POWER TEACH COURSES?
It would be important for the article to present the costs of implementing a system like this, from design to installation.
I have a solar system with two inverters.
one is on grid that injects into the grid and the other is off grid.
shower and air conditioning my system is weak.
but all the lights, sockets, refrigerators and freezers are connected off grid.
I bought it little by little and assembled it, it's a weak system. If there's a power outage during the day when it's sunny, there's no problem, everything works.
if there is a power outage at night it works for 4 hours. if I turn off the freezer and refrigerators cooling it goes all night.
I can use ceiling lights and fans.
There are 10 solar panels and two inverters, a hybrid system. Investment of R$30.000.
next investment is to replace lead batteries with a lithium battery.
That's right! Brazil has politicians interested in maintaining hydroelectric and even thermoelectric plants, because these companies give them a lot of profits, paid by us, consumers of high monthly electricity bills from these sources. If we adopt solar energy, where will the resources come from to maintain their inexhaustible spending on privileges of all kinds? After all, the people vote for cats and dogs that run for office. That's what matters to them, the powerful, of course, with our money, coming from our daily work, not through swiping at other people's things. We will never be independent in the use of renewable energy. On the contrary, the lobby of this gang that hates Brazilians is trying to pass a law authorizing only 30% of Brazilian homes to have solar energy connected to the distribution network. The rest who want to save the miserable salary to which they are entitled, if they work, will have to buy, pay stratospheric interest and still buy batteries to use at night. Being aware that this is what is being designed for us is all we can do. Let us then buy our Solar Energy System, so that one day we can get rid of the distributors by force, through the struggle that is proper to the worker. Yes, Brazil will be a leader in Renewable Energy, only in the segments of society that have their names in the Federal Single Registry. These will receive free Solar Energy, paid for by us, the workers, with a little study, so that we pay income tax, consumption taxes, and are not in the pyramid line called the miserable. But let us fight, while there is still life! The Brazilian people lack intelligence.
Does the payback include the battery prices? Or do the batteries come for free?
I have a 4.6 kW Ongrid system and yesterday there was a storm and I was without power for five hours. It's a hassle. The hybrid system is now available.
How can I communicate?
Good evening. Do you have a company here in Ceará? I am interested in the quote, I live in the rural area and in the mountains.
The nomenclature used in self-generation systems has been confusing. I have read that hybrid is when there is a combination of solar and wind power (with and without a battery bank), and I have also read that when there is solar power with batteries, it is called hybrid and also “on grid with battery backup”. Which is correct?
In Brazil (always late) it is the future, but abroad it has already existed for more than 7 years. LOL

Here the distributor mafia is blocking the progress of all sources and with the help of Aneel (paid with our taxes but lobbying in favor of the distributors), it is as if the patient were donating blood to the donor. I have already sent the distributor in my area out of my life.
I use 90 liters of diesel every month. I have a generator that is on my terrace and is super quiet. It supports all the appliances in the house.
