Battery Charging Stage
The controller have 3 stages charge mode, Constant Current Charging, Constant Voltage Charging and Floating Charging for rapid, efficient, and safe battery charging.

Constant Current Charging (Bulk Charging)
In this stage, the battery voltage has not yet reached constant voltage (Equalize or Boost Voltage), the controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging).

Constant Voltage Charging( Equalize and Boost Charging)
When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant voltage charging mode, this process the charging current will drop gradually.
The Constant Charging has 2 stages, equalize and boost. These two stages are not carried out constantly in a full charge process, and its boost charging is start at 25th of each month

Floating Charging

After the constant voltage stage, the controller will reduce charging current to maintaining the battery voltage on the Floating Voltage set point. Charging the battery with a smaller current and voltage on Floating Voltage stage, while maintaining full battery storage capacity.In Floating charging stage, loads are able to obtain almost all power from solar panel.If loads exceed the power, the controller will no longer be able to maintain battery voltage in Floating charging stage. If the battery voltage remains below the Recharge Voltage, the system will leave Floating charging stage and return to Bulk charging stage.

Maximum Power Point Tracking Technology

This is a MPPT charge and discharge controller, With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of a photovoltaic array, in order to obtain the maximum solar energy in time, which remarkably improves energy efficiency the maximum conversion efficiency can reach 99.5%; the maximum power point tracking is automatically traced, the charging efficiency is increased by 10% to 30% (compared with the controller without maximum power point tracking), with high efficiency/energy efficiency/intelligence.
