Sofar Solar 8 kVA three-phase hybrid inverter - HYD-KTL-3PH
The HYD 5K...20KTL-3PH is a versatile three-phase hybrid inverter for solar and storage applications. During grid failures, it can provide up to 20 kW of unbalanced three-phase emergency power supply (EPS) in 10 ms thanks to its integrated EPS port.
Two MPPTs and two independent battery ports (on models 10K to 20KTL) enable multiple battery capacity configurations in 2.5 kWh steps.
Up to 10 inverters can be connected in parallel on the EPS and AC port, making this device ideal for microgrid installations (on or off-grid).
The integrated energy management system features several user-friendly modes, optimizing the user experience, including an automatic self-use mode. Users can also define different time and/or date ranges, or rules for the day of the week.
All modes can be easily configured on the large LCD display. In particular, this inverter is compatible with SofarSolar's AMASS Store high-voltage battery unit (GTX 3000-H). A WiFi stick is supplied with the inverter, for easy connection to the Sofar monitoring portal.
The SOFARSOLAR residential energy storage system offers more than just a battery solution: it’s a promise of reliability and performance for the years to come, with a 10-year warranty. With its LiFePO4 batteries and distribution unit, you get a modular capacity ranging from 5 to 40 kWh, perfectly tailored to your growing energy needs.
Unmatched Flexibility: The modular, stackable design of the system allows for easy capacity extension, providing you with an evolving and customizable solution to meet your future energy consumption demands.
Seamless Integration: Fully compatible with the HYD 5K-20KTL battery inverter series, our system ensures a smooth installation and usage experience. Whether you’re in a new build or a renovation project, the integration is seamless.
Efficiency and Simplicity: The BDU + Base distribution unit optimizes the management of the battery pack balance for maximum performance, while offering an intuitive user interface with simplified start/stop functions. You’ll enjoy optimal energy management with minimal effort.
And with the 10-year warranty, you can rest assured knowing your investment is protected in the long term. Take advantage of this advanced technology to maximize your home’s energy efficiency while preserving the environment. Don’t miss this opportunity to choose sustainable, reliable energy!
Investment Bonuses for Self-Consumption
The State encourages the installation of solar panels by offering a bonus adjusted according to the capacity of the installation. However, it is subject to strict criteria, reserving its allocation to eligible households.
The self-consumption bonus is conditioned by photovoltaic self-consumption and the sale of surplus, which is mandatory for designated buyers, with rates revised quarterly. Opt for solar panels on your roof with overlay installation, requiring the intervention of a certified professional and a power limited to 100 kWc. Ground-mounted panels are not eligible.
The photovoltaic self-consumption bonus depends on the size of your installation and varies each quarter. It is determined by four categories based on the peak power of the installations:
In summary: a more powerful installation translates into a lower bonus, hence the importance of optimizing your self-consumption.
Below are the bonus rates for installations (from 1 November 2024 to 31 January 2025):
To estimate your bonus, multiply the rates by your installation's capacity. For example, a 7 kWc installation would be eligible for €1,540 (€220 x 7 kWc).
The Energy Regulation Commission adjusts the self-consumption bonus quarterly based on the number of new requests for connection to the distribution network, such as Enedis. The current rates are accessible here
The self-consumption bonus request is automatically activated after your photovoltaic installation is connected. Once validated, the amount remains fixed despite quarterly rate variations.
The bonus is paid by a designated buyer one year after commissioning, along with the income from surplus sales, except for installations over 9 kWc, which receive 80% immediately and the rest over four years.
Remuneration for Surplus Sale
Owners of self-consumption solar installations with surplus sales provide green electricity to neighboring households by selling the excess to designated buyers like EDF OA. Enedis covers the connection costs, thereby encouraging the energy transition to renewable energy.
The purchase amount for surplus electricity depends on the installed capacity and fluctuates quarterly, defined according to four categories based on the peak power of the installations.
Below are the rates (from 1 November 2024 to 31 January 2025) as follows:
Once the contract is established, this rate remains constant for a period of 20 years, covering the entire duration of the agreement.
To benefit from self-consumption with surplus sales, the solar panels must be installed on a roof and connected to the electrical grid to inject the surplus. Isolated sites are not eligible. The excess electricity produced is sold to a designated buyer in the absence of storage
The application for the self-consumption bonus is activated automatically after your photovoltaic installation is connected. Once validated, the amount remains fixed despite the quarterly tariff variations.
Make an initial work declaration to the town hall.
Seek the services of an expert for the installation of solar panels.
Submit a connection request to the relevant authorities.
Establish a contract with a mandatory buyer.
For invoicing the surplus electricity, the process is quick and simple: once a year, on the anniversary date of the contract's start, take a meter reading.
