4 days ago by MORNSUN

This article introduces MORNSUN's PV200-29Bxx series and LMF150-20Bxx series.

The proportion of solar photovoltaic power generation systems in the Power Grid is gradually increasing. How to ensure the reliability and safety of the power supply draws a big challenge for the Power Grid. In an Energy Storage System(ESS), batteries are generally installed in the Battery Container according to the international standards, which consists of batteries, Battery Series Control Unit(BCU), HVAC, fire suppression system, etc.

MORNSUN is always providing you with the diverse power solutions for the Energy Storage Industry. Check out below the BCU power solution for the Battery Container.

 

Power requirements of BCU in the Battery Container
