How long does a fully charged Bull energy storage product last?

Battery life depends on the energy consumption rate and the size of the energy storage system. It can be calculated by dividing the battery capacity (kWh) by the load power (kW). For example, a 30kWh Bull energy storage product lasts approximately 15 hours on a full charge at an average load of 2kW; and over 30 hours on a single charge at an average load of 1kW.

What are the charging methods for Bull energy storage products?

Bull energy storage products can typically be charged via AC adapters, solar chargers, and car chargers. Some models also support generator charging, dual AC charging, or dual solar panel charging. Please consult the product manual or customer service for specific charging methods.

What maintenance is required for Bull energy storage products?

Bull energy storage products require virtually no maintenance. However, users should ensure that the battery charge level never drops below 10%. Before long-term storage, the device should be fully charged and connected to the dedicated maintenance input port, maintaining a constant single-phase AC power supply.

FAQ – Flexi 3.0 3-Phase Hybrid Storage Inverter (20–30 kW)

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 output ranging from 20 to 30 kW, designed for solar energy storage in large residential properties or small commercial businesses with significant energy consumption.

Compared to the Flexi 2.0 Three-Phase (8-12 kVA), the Flexi 3.0 represents a major leap in performance: it handles larger PV arrays, supports multiple MPPT strings, and features advanced functions such as an integrated AI-EMS, which automatically regulates operation based on real-time energy tariffs.

What type of batteries does it support, and what storage capacity is achievable?

It supports high-voltage batteries ranging from 150V to 800V and is compatible with lithium-ion, lead-acid, and sodium chloride chemistries. The maximum charge/discharge current is 50A/60A/60A (corresponding to the 20/25/30 kW models, respectively), with power ratings of 20, 25, and 30 kW. Battery packs are expandable up to 8 units, allowing you to scale capacity according to your specific needs.

How does a bidirectional inverter work in a photovoltaic storage system?

In a photovoltaic system with energy storage, the inverter performs three main functions:
1) DC-AC Conversion: it converts the direct current from the solar panels into alternating current for household use; 2) Battery Management: it charges and discharges the connected battery pack (150–800 V), optimizing the cycles based on electricity tariffs and consumption;

An on-grid/off-grid solar inverter: what does it mean, and when is it needed?

An "on-grid/off-grid inverter" refers to an inverter's ability to operate both while connected to the electrical grid (on-grid) and in complete autonomy (off-grid), without relying on the public utility network.

The Flexi 3.0 Three-Phase features an integrated off-grid switch with a transfer time of less than 10 ms—so rapid that critical loads (refrigerators, servers, medical equipment) do not even detect the disconnection from the grid. The backup mode provides up to 150% peak overload capacity. This functionality is essential in areas with an unstable power grid, for those wishing to maximize their energy autonomy, or in remote applications where grid connection is limited or costly.

What is a three-phase inverter, and when is it necessary?

A three-phase inverter is a device that converts the direct current (DC) produced by solar panels into alternating current (AC) distributed across three electrical phases, rather than just one as in the case of a single-phase system.

It is necessary when the installed power capacity or energy consumption exceeds the capabilities of a single-phase system (generally starting from an installed capacity of approximately 6–10 kW), or when the residence is already equipped with a three-phase connection.
