The Black & Blue Series represents the Jarrett Solar mission of integrity and innovation within the global PV market. The core of the unit is a high-speed Single-Chip Microcomputer (SCM) which allows for a precise digital control of the entire charging process.
Optimal Battery Maintenance: High-efficiency PWM charging in our battery controller allows for optimal current management to avoid gassing and overheating of your battery banks. Precise and correct charging of your batteries is at the core of a long lasting solar system, protecting the internal core of the batteries.
Automatic Voltage Recognition: Designed for a “simpler and more convenient” user experience, the controller automatically identifies standard system voltages (12V/24V). This “plug-and-play” capability allows for seamless integration into diverse “industrial, commercial, and residential” energy setups.
As a pragmatic and innovative company we adhere to a business strategy, which for the Black & Blue Series translates into professional control combined with ease of use for every user.
Clear LCD Visualization: The fixed LCD screen provides a real-time window into your system’s operation. Users can instantly monitor battery levels, charging status, and system health through reliable data displays.
Two-Button Operation: The interface to the man-machine interface has been reduced to two simple push buttons. The so-called “humanized browser design” of the system for viewing and editing data in the system makes it superfluous to read through extensive technical descriptions in order to change settings.
Programmable Flexibility: Every energy application is unique. The energy controller is flexible and allows users to set up a variety of parameters for controlling and monitoring the energy system. For example, the controller allows users to choose from up to 3 different battery types (Gel, Sealed, Flooded) and also offers a variety of load control options that can be set up for a specific energy project.
Safety Series provides protection for your electronics and automobile circuits with a comprehensive package of automated safeguards.
Total Protection Suite: Each unit includes advanced protection for over-charging, over-discharging, short-circuits at the output, overloads and reverse polarity.
Unattended Reliability: This functionality allows a system to operate independently and maintain stability and performance in so-called “unpowered areas” and enable operation of remote locations such as border defense posts, island going fishing boats and isolated farms in the forest, without continuous monitoring by an operator.
Rational Energy Conservation: Black & Blue series prevents deep discharge and avoids electrical spikes. Hence, solar power becomes more cost efficient for the end customer and energy is being saved in a rational manner and to an adequate extent through consumption reduction.
The Black & Blue Series is designed for off-grid solar energy application projects. The Series is widely used in several different markets and applications.
Solar Streetlighting: Suitable for public utility projects that need to automatically switch on and off at dusk and dawn.
Solar Panels Residential – Off Grid Power Generation for Home – Lighting, fans, appliances, for homes in rural settings with off grid villas.
Agricultural & Forestry Use: Smaller irrigation systems and also forest monitoring equipment require ‘cleaner, noise-free’ energy.
Mobile Power Solutions: Rugged look and good performance. The battery supplier for maritime solar power and portable power supplies for field service.
