What is an EMS controller?

BWN POWER BP series EMS controller has a powerful and advanced system integrating (MPPT+AC) battery charger and energy management functions. 

It works together with our BP series micro-inverter and will magically create a home solar micro-energy storage system with a maximum output power up to 4KW. 

The micro-energy storage system supports switching between grid-connected, energy storage, and off-grid modes. And it can run with battery alone when the mains power is cut off, so as to ensure continuous power supply at home. 

In addition, the EMS controller has the adaptive function of wide-voltage battery, so that customers can choose batteries of different voltages: (12V/24V/36V/48V) 

And different types of batteries: (lead-acid batteries, lithium batteries, or others). 

The EMS controller adopts a high-performance aluminum alloy die-casting sealed design shell, which can continue to operate in harsh natural environments.

Detailed Description

What are the characteristics of the controller?

1)IP65 natural heat dissipation 

High-strength one-time forming aluminum alloy die-casting outer housing ensures that the entire controller achieves IP65 degree of protection. So as to satisfy customers For use in harsh environments.

2)Dual charging mode 

Integrated MPPT solar charging and AC city electricity charging, let the mains charge as the sun chargeable compensation is possible. Multiple charging and storage to meet different usage needs

3)Adapt to different batteries comes with 12V-48V battery automatic identification function.
Yes. AC charging does not pick the battery, and to achieve a multi-purpose machine, saving additional cost to buy a different charger.

4)Various communication methods 

RS485/CAN communication mode multiple choice, it can be matched with different energy storage batteries. Know the operating status of the battery at any time to ensure the system is more secure and stable.

5)Remote monitoring 

Built-in Bluetooth or WIFI communication module, through the system can be accessed through a mobile phone or a computer real-time monitoring. Make sure users are first to understand the operating status of the system.
