When it matters most.
Power fast, reliable, and ready for anything.
You can easily install up to 6 kWp of solar panels, starting with a minimum of just 4 panels. This flexible system allows you to scale your solar setup according to your energy needs, ensuring efficient and reliable power generation wherever you are.
Barrel Master comes equipped with 4.8 kWh of lithium battery storage, providing reliable energy right from the start. For larger energy needs, you can expand the system by adding Barrel Batteries, each with a capacity of 20 kWh, up to a total of 80 kWh.
Barrel is equipped with a powerful 6 kVA single-phase inverter, providing up to 32 A at 220 V. This capacity allows it to power a wide range of devices and appliances, such as refrigerators, air conditioners, electric ovens, , water pumps, lighting systems, and workshop equipment.
A 6 kWp solar system installed in Ghana can generate an average of 25-30 kWh of energy per day, depending on local solar conditions. This amounts to an annual production of approximately 9,000-11,000 kWh, enough to power a household or small business.
Energy Independence
Barrel is a fully off-grid solution that allows you to generate, store, and use solar energy even without grid access. Our units are perfect for providing power in remote areas or emergency situations.
Continuous Operation
Thanks to the built-in backup system, Barrel ensures continuous power, even during blackouts or grid failures, making it indispensable for healthcare facilities, assistance centers, and critical areas.
Compatible with Generators
Barrel can be connected to a diesel or gas generator as an additional backup source. The system automatically manages the generator startup when needed, optimizing energy resources and ensuring a constant power supply.
Compatible with all Solar Panel
The Barrel system supports the installation of any type of solar panel, both flexible and rigid, up to a maximum of 6,000 watts. You can connect up to 14 panels of 420W in one strings of 7 panels each. The panels are wired in series due to the high-voltage MPPT, ensuring maximum efficiency. The maximum voltage supported per string is 500V (open-circuit voltage - Voc).
Flexible and Scalable Storage
Barrel can be expanded with 20 kWh extensions up to a maximum of 80 kWh, providing incredible flexibility. Moreover, Barrel can be configured as a three-phase system using three combined Barrels and can be paralleled with up to 10 units. With Barrel, creating microgrids becomes easy, enabling autonomous energy solutions for communities or facilities.
Protection and Durability
The Barrel system is housed in a robust steel barrel, making it difficult to tamper with or steal. It can be securely fixed to the ground with strong bolts and left in public areas safely. The system is equipped with heat extraction and protected against rain, ensuring reliable operation in all weather conditions. The standard barrel size, allows for easy transportation anywhere.
Electricity everywhere
Barrel’s versatility provides users with a fast and efficient solution to the lack of electricity from the national grid, alongside smart management of loads, energy needs, and consumption.
In the absence of a grid, Barrel operates seamlessly, ensuring no blackouts. The system is highly advanced, fully programmable, and intelligently integrates all available energy sources (grid, generators, solar panels, batteries, and wind), offering a strategic advantage in terms of reliability, cost efficiency, and environmental impact. Additional energy sources can be connected without modifying the hardware.
Barrel is a professional solar hybrid system featuring a state-of-the-art energy storage solution. It is a plug-and-play system that’s easy to use, transport, and fully modular. A true off-grid solution ideal for small offices, homes, water pumps, humanitarian and emergency interventions, ATMs, and commercial activities.

How is work
Off grid single-line diagram
You can also add a genset. Genset (diesel generator) serves as a backup power source, connected via a DDG (Diesel Generator Disconnect) for switching between power sources. The privileged users receive power from the system via AC output. In essence, this system allows for autonomous power generation and storage without relying on the main grid.
Barrel Wins Pv Magazine Award for Innovative Hybrid Solar Solution Offering Scalable and Flexible Energy Systems
An innovative product designed to allow the quick deployment of systems while maintaining scalability,” says BESS juror Chris Wright. “The hybrid controller that supports integration of solar PV, battery storage, a diesel genset, and flexibility for on-grid or offgrid installations provides substantial flexibility in system configuration and applications.
