IP66 protection
Built for Different Environments
The hybrid inverter features IP66 protection, while the battery enclosure is rated IP65, helping protect the system against dust and water exposure when installed in accordance with local requirements. Natural convection cooling also reduces operating noise and avoids the maintenance requirements associated with cooling fans.
From 3.68 kW to 12 kW
Flexible Hybrid Power
R-ESS is available with hybrid inverter power ratings from 3.68 kW to 12 kW, covering smaller residential systems as well as homes with higher electricity demand. Both single-phase and three-phase configurations are available.
Modular & Stackable Design
Scalable Battery Storage
Each battery module provides 5.12 kWh of energy capacity. The modular design allows the storage capacity to be configured according to household electricity consumption, solar generation and backup requirements. Available system configurations can scale up to 40.96 kWh, depending on the inverter model and battery arrangement.
Dual MPPT
Capture More Solar Energy
Two independent MPPT trackers allow R-ESS to manage separate solar arrays more efficiently, even when panels face different directions or receive different levels of sunlight. This gives installers greater design flexibility while helping homeowners capture more energy from their rooftop solar system.

FAQ
What is the R-ESS home energy storage system?
R-ESS is an integrated residential energy system combining a hybrid solar inverter, modular LFP battery storage, backup power capability and intelligent energy management.
It manages how solar energy, battery power and grid electricity are used throughout the home.
How much battery capacity does R-ESS provide?
Each battery module has a total energy capacity of 5.12 kWh and an approximately 4.6 kWh usable capacity.
The total system can be expanded according to the selected inverter and battery configuration, with available configurations reaching up to 40.96 kWh.
How do I know how much battery capacity my home needs?
The right capacity depends on your daily electricity consumption, solar generation, evening usage, backup requirements and electricity tariff.
A smaller system may be suitable for increasing solar self-consumption, while a larger system may be needed for longer backup duration or higher household loads.
Can R-ESS power my home during a blackout?
R-ESS supports backup power operation. During an outage, it can supply selected essential loads connected to the backup circuit.
The available backup duration depends on battery capacity, battery charge level and the power consumption of the connected appliances.
Can R-ESS power the whole house?
This depends on the inverter power rating, battery configuration and maximum household load.
For many projects, installers create a dedicated backup circuit for essential appliances such as lighting, refrigeration, internet equipment and selected sockets. Larger systems may support more loads when designed accordingly.
Can the battery charge from the grid?
Yes. The system can be configured to charge from the grid, which is useful in markets with time-of-use tariffs.
For example, the battery may charge when electricity is cheaper and discharge during more expensive periods.
Can R-ESS reduce my electricity bill?
R-ESS can help reduce grid electricity purchases by storing surplus solar and using it later.
In markets with time-of-use tariffs, it can also shift electricity use from higher-price periods to lower-price periods. Actual savings depend on electricity prices, solar generation, household consumption and system configuration.
