The OffGridBox FLEX is a modular solar power system, each consisting of a 2 or 3kVA inverter, solar charger, 1.6 to 2.4 kWp solar PV, and 2.5-5 kWh lithium battery. It can be scaled up to 4 modules in parallel.
It is ideal for homes in more developed countries, or to power health clinics and schools in the Global South.
So far, we have deployed several of these systems in Tanzania, Rwanda and DRC, as well as in Italy.
A standard 1.6 kWp FLEX system
TECHNICAL SPECIFICATIONS OF A SINGLE FLEX SYSTEM

To maintain the same consumption habits at home, it is recommended to combine two FLEX systems right from the start.
This way you will always have 3200W at your disposal, just like the vast majority of home supplies from the national grid.
FLEX systems can be combined up to a maximum of four, for 8-12 kVA of single-phase power and a maximum of 9.84 kWp of photovoltaics and 40.8 kWh of lithium storage.
Inverter Board
This is the heart of the whole system, it plays the important role of transforming solar energy into usable energy from your home, with the exact same standards as what you use now from your meter.
The FLEX either has a 2kVA or 3kVA Inverter
Solar PV
4 to 6 High-efficiency photovoltaic panels of 410Wp each capturing the sun's energy. Free, clean, independent energy. (Roof mounting system can be provided). Half Cut technology to optimize yield in low light conditions, ultra-dense (209.72 W/ m2). Linear performance for 25 years is guaranteed.
Lithium battery
In order to make the best use of the energy the system produces, it is essential to have high-performance energy storage. By doing so, even at night or at times of low solar irradiation, you can have the energy you need. Battery capacity 2500Wh LiFePO4 technology, cell-level balancing BMS. Built-in Bluetooth monitoring.
