Blue Line PSHS 3000 is an autonomous Fosera Pico Solar Home System with 3,25 V and over-charge, deep discharge and over-current protection. It is a plug and play device designed to power multiple Fosera lights, the Fosera radio, mobile phones and MP3-players. Multiple Fosera battery boxes can be interconnected to increase the capacity of the system. This product is also available with Pay-As-You-Go functionality.
The device is engineered in Fosera‘s head office located near Ulm in Illerkirchberg, Germany.
Distributors / Implementing Organizations
Fosera's team is formed by engineers, salespeople and operation managers. Apart from the main production facilities in Thailand (in Bahir Dar) and by 2016, there were operating local assembly lines in India, Mozambique, Kenya (in Naivasha), and Ethiopia (in Pathum Thani) all operating under rigorous German Quality Control and with plans to expand to Liberia.
Each of Fosera's battery boxes are meant to be custom-bundled with various appliances (lighting, radio, mobile phone charging) and various size PV solar panels depending on the environment in which they're located. Around 100 battery boxes are produced every month. Interview with the represenative Engineered in Fosera's head office located near Ulm in Illerkirchberg in Germany, Fosera has 5 operating assembly lines on 3 continents. The main production factory is in Thailand (in Pathum Thani), followed by India, Mozambique, Kenya, and Ethiopia all operating under rigorous German Quality Control and with plans to expand to Liberia.

Fosera Blue Line PSHS 3000 is a Lithium Iron Phosphate battery box with 3,25 V of nominal voltage and 3 Ah of system capacity. Its dimensions are 192 x 131 x 45 mm and it weights 0,325 kgs. The recommended module is a crystalline silicon panel with 1,5 Wp of peak power and 0,34 A of module current. The cable from the solar panel to the battery box is 6 m long. Further details about the design specifications in the product datasheet.
This battery box has 3-year warranty covering manufacturing defects. It is easily replaceable with common tools, however, the warranty is void when the product is opened.
Up to 10 years maintenance-free.
Manufacturer Specified Performance Parameters
Fosera is working for bringing power to Africa, Asia and Latin America with clean, sustainable and affordable solar energy systems and solutions what fit users need.
Vetted Performance Status
When connected to the 1,8 Wp polycrystalline silicon module, the battery box powers the 100 Illuminance Fosera lamp for 14 hours and the 50 Illuminance lamp for 32 hours. Per day of solar charging, it is 7,6 hours for the 100 lm lamp and 18 hours for the 50 lm lamp, resulting in a total light output of 97 and 39 lumens, respectively. Total lightning service for this product is 740 lumen-hours/solar-day for high brightness setting (100 lm lamp) and 700 lumen-hours/solar-day for low brightness setting (50 lm lamp). Complete vetted performance in the Lightning Global assessment here.
The battery box is a plug and play device, however, electrical installation and control guidelines provided by Fosera must be followed to avoid electrical shocks.
