Today, GSL ENERGY offers lower cost-effective 240KWH 48VDC 5500AH Lifepo4 battery storage system to Indonesian clients.
The 240kwh lifepo4 battery system is made by 5 sets of 48V 1100AH lifepo4 battery modules together. Each module is made by 15s4p= 60 pcs GSL-LFP275 3.2V 275AH prismatic lifepo4 battery cells and smart BMS together.
GSL ENERGY will offer 10 years warranty on the full storage system.
“It is a big challenge for us, in fact, “said by Mr Jim Deng, CEO of GSL ENERGY, “ and I am very proud of our ESS bms and pack engineer R&D teams. It is really a very difficult project we have met these years because client budget is limited and cannot accept expensive high voltage 264kwh 768VDC solutions at first time. It is not easy to install big 264kwh high voltage ESS storage system, too. At first, we are going to use 5U 48v 100ah light modules but it needs 11 pcs* 5=55 pcs to balance together. That will be not stable to connect so many pcs together and BMS also cannot handle so big huge discharge request to loading, too. We have meetings for 2 days together and finally we decide to use low voltage of 48VDC lifepo4 battery system solution to match GSL hybrid 8kva smart solar inverter with 6 pcs parallel to make ESS264KWH-50KVA input and output finally. “
GSL ENERGY new design 48V 1100AH is just made by just 5pcs 9.6V 1100AH 6U RACK modules connect in series , not like traditional parallel solutions and a central smart BMS to work together. Client can install and connect them very easily.
“ It is for our remote island solar storage system, “said by Mr. Sam, CEO of Indonesian solar company, “ Our budget is limited and we need light weight solutions, too. Furthermore, we have to use low voltage DC solutions for safety during installation. High voltage DC battery system is not familiar with us. We also consult with a lot of Chinese factory suppliers and we are so lucky to find GSL ENERGY partner who can offer our satisfied solutions finally. We bought 3 sets 48V 5000AH from GSL ENERGY for our three remote village in island for thousands of people using green electricity during days and nights. ”
GSL ENERGY use smart BMS ( design for EV BUS ) via big screen to handle 15pcs 3.2V 1100AH cells module balance using EV battery design concept. Each 48v 1100ah lifepo4 battery can communicate with Canbus protocol agreement to balance each other to make full system pack working perfectly and coordinately.
“If the systems are installed and run perfectly, we will buy more sets for our company other projects in other remote islands soon, said by Mr. Sam. “ we will look forward to more cooperation with GSL ENERGY in 2020 for powerwall and rack-design lifepo4 battery storage system in 2020. "
