The evolution of the photovoltaic sector goes far beyond energy generation. In a scenario marked by unstable grids, constantly changing tariffs, and increased demand for energy autonomy, energy storage is taking on a prominent role. It is in this context that Hoymiles is expanding its operations and presenting the public with a robust portfolio of hybrid inverters, designed to guarantee continuous energy supply, advanced management, and maximum application flexibility.
Hybrid systems allow for the integration of photovoltaic generation, batteries, and the electrical grid into a single solution. In practice, this means:
- Continuity of power supply in case of grid failure;
- Greater use of the generated solar energy;
- Cost reduction through strategies such as peak-shaving and time-of-use;
- More control and predictability for the end consumer.
Hybrid inverters Hoymiles They were developed precisely to meet the most diverse applications and demands, through their intelligent management system, fast switching for backup, and compatibility with different network architectures.
HIS: inverter for single-phase 220 V systems
The HIS-(3–6)L-G3 series is the gateway to smart home storage. Developed for 220V single-phase networks, the HIS combines ultra-thin design, high efficiency, and advanced energy management features.
Among the main distinguishing features of HIS are:
- Power ratings from 3 kW to 6 kW, ideal for residential use;
- Instantaneous switching (0 ms), ensuring continuity for critical loads;
- Integration with lithium or lead-acid batteries;
- Oversizing of 200%;
- Intelligent operating modes such as self-consumption, backup, peak-shaving and time-of-use;
- Input for generator, allowing AC coupling with microinverters.
Furthermore, monitoring via S-Miles Cloud allows for remote tracking, diagnostics, and continuous system optimization.
Ideal application: homes seeking energy independence, quick backup, and greater control over consumption.
HYS: Inverter for 220V two-phase and 127V single-phase networks.
Designed specifically for markets with more complex electrical architectures, the HYS-7.5LV-USG1 caters to split-phase networks, which are very common in 220 V two-phase systems with 127 V single-phase branches.
This hybrid inverter stands out for its versatility and robustness:
- Nominal power of 7,5 kW;
- Instantaneous switching (0 ms), ensuring continuity for critical loads;
- Integrated protections, including AFCI and RSD (Rapid Shutdown);
- Maximum output power of 15 kW for up to 10 seconds;
- Intelligent operating modes such as self-consumption, backup, peak-shaving and time-of-use;
- Input for generator, allowing AC coupling with microinverters.
HYS delivers a complete solution for those who need flexibility without sacrificing security, efficiency, and intelligence.
Ideal application: larger residences and small businesses with two-phase or mixed electrical networks.
HIT: Three-phase inverter for high-power applications (380 V)
For large-scale commercial, industrial, or residential projects, Hoymiles offers the HIT-(5–20)L-G3 series, a line of high-performance three-phase hybrid inverters.
HIT was developed to handle high loads, phase imbalances, and advanced energy management strategies.
- Power ratings from 5 kW to 20 kW;
- 100% unbalanced output, with up to 50% of the power per phase;
- Up to 4 MPPTs, with a maximum current of 20 A, a short-circuit current of 30 A, and a maximum input voltage of 1.000 V.
- Oversizing of 200%;
- Compatibility with peak-shaving and time-of-use;
- Input for generator, allowing AC coupling with microinverters.
The result is a highly scalable solution, prepared for critical demands and environments that require absolute reliability.
Ideal application: commercial establishments, industries, condominiums, and three-phase systems in general.
Generator Gate and AC Coupling
The generator port is a dedicated AC input found on Hoymiles hybrid inverters (HIS, HYS and HIT), originally designed for connecting combustion generators (diesel, gasoline or gas).
From an electrical and functional point of view, this door is:
- An AC input controlled by the EMS (Energy Management System);
- Capable of accepting an external source of alternating current;
- Integrated into the prioritization logic between PV, battery, grid, and external source.
In other words, the inverter doesn't just "receive" energy from the generator: it decides when, how, and how much to use, and can even charge batteries from that source.
In AC coupling, the photovoltaic generation does not enter the hybrid inverter from the DC side (strings), but rather from the AC side, in this case, through the use of microinverters.
This topology is extremely useful in:
- Retrofitting existing systems;
- Projects that combine microinverters and energy storage;
- Systems that require high flexibility and future expansion.
In addition, the generator gate has:
- Current and power measurement;
- Overcurrent and overvoltage protection;
- Full integration with backup mode.
This allows the system to function in both:
- Connected to the network;
- In isolated mode, with active microinverters.
Advantages of AC coupling via generator gate
- Leveraging existing systems;
- High scalability and modularity;
- Compatibility with Hoymiles microinverters;
- Reducing losses in distributed projects;
- Continued generation even during power outages;
- Architecture aligned with the concept of intelligent storage.
The future of storage starts now.
With its HIS, HYS, and HIT portfolio, Hoymiles delivers complete solutions for different consumer profiles and electrical grids, always focusing on uninterrupted power, operational intelligence, and scalability.
Energy storage is no longer an add-on but has become central to energy strategy, and Hoymiles is ready to lead this movement.
