PRODUCT BENEFITS

1 MAKE A DIFFERENCE. USE SMART ENERGY.

In pure lead acid systems, batteries often fail within 1 to 3 years, as batteries get damaged by continuous operation at low states of charge. Pure lithium systems perform way better and show a longer lifetime but are very expensive. Initial investment costs for hybrid systems are close to the costs of pure lead acid systems and approx. 50% lower than pure lithium systems. As costs per stored kWh are around 60% lower in hybrid systems than in lead acid systems, the hybrid system becomes the most cost-effective option already within the first 3 years.

2 EASY UPGRADE OF LEAD ACID SYSTEMS

In existing lead acid systems the battery capacity can be increased by adding lithium whereas it is technically not recommended to mix old and new lead acid batteries. As BOS hybrid systems feature state of the art lead acid charging, all different kinds of lead acid systems can be upgraded. In existing off-grid systems, the old charge controller simply needs to be replaced by the BOS hybrid system. This improves system performance and decreases power costs immediately. The electrical installation can stay the same, hence efforts and additional costs are minimized.

 

3 CHARGE YOUR SYSTEM FROM THE GRID AND POWER AC LOADS

Hybrid Storage systems can be charged from the grid during hours of available power in order to use the power stored in the hybrid system as backup once power outages occur. To power bigger AC loads such as big-screen TVs or small pumps, an external inverter simply needs to be connected to the lead acid battery. The system needs to be sized properly and the use of high quality inverters is recommended.

1. Standard solar panel power supply as DC input. 2. Optional AC input through AC/DC converter (no feed-in into AC grids possible). The HS hybrid systems have a standard DC input connector for use with standard chargers (similar to notebook chargers). Please ask for recommended chargers. 3. HS hybrid battery system consisting of charge regulator with integrated lithium battery and external lead acid battery. 4. Optional AC output through an DC/AC inverter connected at the lead acid battery. This enables the powering of bigger AC loads such as big screen TVs or small pumps. Please ask for recommendations on inverters. 5. DC loads on the standard load outputs, such as highly efficient LED lamps, DC TVs, DC fans etc.

 

4 EASE OF INSTALLATION

The BOS hybrid battery management systems simply need to be connected to a lead acid battery, the solar generator and to the loads. As the voltages stay in the lower range, the system can be easily installed.

5 INCREASE OF SYSTEM LIFETIME

The lead acid battery is not strained by deep charging cycles, as the lithium battery is used for running daily cycles. During its long hours at full state of charge the lead acid battery is floated. Compared to pure lead acid systems both effects positively impact the lead acid battery lifetime. By preventing harmful sulphation the lifetime can be increased to more than 10 years. This lowers energy storage costs significantly and has a positive impact on the environment. The lithium battery offers enough charging cycles for more than 10 years of daily use.
