FAQ
What is the Flexi 3.0 Three-Phase 20-30kW and who is it intended for?
What is the Flexi 3.0 Three-Phase 20-30kW and who is it intended for?
The Flexi 3.0 Three-Phase 20-30kW is a three-phase hybrid inverter with a power range of 20 to 30 kW, designed for solar storage in large homes or small commercial businesses with significant consumption.
Compared to the Flexi 2.0 Three-Phase (8-12kVA), the Flexi 3.0 represents a major performance leap: it manages larger PV fields, supports more MPPT strings, and features advanced functions such as integrated AI-EMS, which automatically adjusts operation based on real-time energy tariffs.
What type of batteries does it support and what storage capacity can be achieved?
What type of batteries does it support and what storage capacity can be achieved?
It supports high-voltage batteries from 150V to 800V, compatible with lithium-ion, lead-acid, and sodium-chloride. Maximum charge/discharge current: 50A/60A/60A (respectively for 20/25/30 kW), with power of 20/25/30 kW. Battery packs are expandable up to 8 units, scaling the capacity according to your needs.
How does the bidirectional inverter work in a photovoltaic storage system?
How does the bidirectional inverter work in a photovoltaic storage system?
In a PV system with storage, the inverter performs three main functions:
1) DC-AC conversion: converts the DC current from solar panels into AC current for domestic use.
2) Battery management: charges and discharges the connected battery pack (150-800V), optimizing cycles based on tariffs and consumption.
3) Off-grid backup: in case of a blackout, it automatically switches (<10ms) to island mode, powering critical loads using stored energy or residual PV production.
The Flexi 3.0 Three-Phase integrates all three functions into a single device.
What does a solar inverter "on off grid" mean and when is it needed?
What does a solar inverter "on off grid" mean and when is it needed?
An "on-off grid" inverter refers to the ability of an inverter to operate both connected to the electrical grid (on-grid) and completely autonomously (off-grid), without relying on the public grid.
The Flexi 3.0 Three-Phase integrates an off-grid switch with a transfer time of less than 10ms — so fast that critical loads (refrigerators, servers, medical devices) do not even notice the disconnection from the grid. The backup mode provides up to 150% peak overload capacity. This feature is essential in areas with an unstable grid, for those who want to maximize energy independence, or in remote applications where grid connection is limited or costly.
What is a three-phase inverter and when is it necessary?
What is a three-phase inverter and when is it necessary?
A three-phase inverter is a device that converts DC current from solar panels into AC current distributed across three electrical phases, rather than just one as in single-phase systems.
It is necessary when the installed power or consumption exceeds the capacity of a single-phase system (typically starting from around 6-10kW of installed power), or when the building is already equipped with a three-phase connection.
