Energy Storage Systems
The SF -HVT series household lithium batteries adopt afully automatic thermal management system, CTP no-moduletechnology, high-efficiency heat pump heating technology, andaluminum alloy body design, which will expand the workingtemperature range of the battery,increase the consistencybetween battery cells, and achieve a more flexible appearancedesign. This will achieve a new generation of householdenergy storage lithium batteries with safer, more exquisite, andlonger service life.


SOLARFIRST's self-developed lithium battery thermal management system(BTMS)ismainly alithium battery temperature control technology system that uses circulating liquid as the medium for heat exchange.


The CTP technology(Cell To Pack)of SOLARFIRSTThe CTPhousehold energy storage lithium batteries directly integratesthe battery cells into a battery pack, subtracting the modulelink, forming a non module form, which improves the overallenergy density.The battery thickness is only 18cm,significantly reducing the volume and failure rate compared todomestic high-voltage stacked lithium battery products on themarket, greatly improving safety, and having no wiring harnessand connector connections between modules, making thestructure simpler, Installation is extremely convenient, whilealso reducing the weight of the battery pack.
