MeritSun-The enterprise who had passed UL 1973 new standard Certification


Underwriters Laboratories (UL), one of the leading safety certification companies in the country, has awarded a certificate to MeritSun.

MeritSun is also one of the China rare companies that have passed the latest version of the UL1973 testing standards.

UL 1973 outlines a series of safety performance tests for energy storage solutions, including electrical tests such as an overcharge test, short circuit test, over-discharge protection test, temperature, and operating limits check test, imbalanced charging test, dielectric voltage test, continuity test, failure of cooling/thermal stability system test, and working voltage measurements. In addition, UL 1973 requires testing of electrical components; including a locked-rotor test for low voltage direct current (DC) fans/motors in secondary circuits, input, leakage current, a strain relief test, and a push-back relief test.

Mechanical tests are also required by UL 1973, including a vibration test, shock test, and crush test, which only apply to LER applications. Other mechanical tests that apply to all systems include a static force test, impact test, drop impact test, wall mount fixture/handle test, mold stress test, pressure release test, and a start-to-discharge test.

Additional environmental tests are also required by UL 1973, including a thermal cycling test, resistance to moisture test, and a salt fog test.

MeritSun cell was proven to be pretty good performance and Superior safety according to the testing status. During module-level testing, the thermal runaway did not spread to all cells. no fire, no splashes, which shows the safety and reliability of the module design.
