Safest – ZRGP’s Mate (LFP) Passed the UL9540A test

ZRGP is pleased to announce passing UL 9540A test at the cell, module, and system level, which means that Mate, ZRGP’s home energy storage system, has reached the highest international standard level in terms of safety and reliability. The passing of this test will help its business to grow globally.


What Is UL9540A?

Based on high standards of international certification, reliable R&D strength, and scientific technology training, ZRGP is committed to providing customers with the safest, most economical, and most efficient energy storage systems.

The UL9540A test standard is a test method proposed by UL to evaluate the spread of large-scale thermal runaway fires in electrochemical energy storage systems and has become a landmark industry standard.

In doing so, ZRGP has demonstrated that its product meets the industry’s highest standards for safety and fire prevention.

There are 4 stages in the UL9540A test method:


At this level, UL looks at whether a cell can exhibit thermal runaway. It also checks its characteristics and flammability.


In this stage, the main goal is to determine if thermal runaway propagates with the module. They will also find out the heat release and gas composition.


Now they will look at the whole unit and see the following. Firstly, they find out how quickly fire spreads. Then they will look for its heat and gas release rates and other hazards.


Lastly, they do an installation test. This is an optional test, but its goal is to determine how effective the product’s fire protection is.

ZRGP PowerBase X1 = Energy Security + Energy Freedom

Rooftop solar systems enable homeowners to produce affordable and renewable energy to power their homes. However, due to grid safety protocol, a solar system, unfortunately, cannot provide energy to the home during a power outage. That’s where PowerBase X1 comes in.

During a blackout, X1 will enable a rooftop solar system to produce energy for the home during a power outage. Any unused solar energy can be redirected to charge the battery; this energy can then be used when the sun goes down. In this way, X1 gives homeowners true energy security and freedom.

What’s more, X1 can be equipped with 16 mainstream inverters that work together to keep the battery in operation. This is unrivaled in the industry and you don’t have to worry about system defects caused by incompatible inverters.

PowerBase X1 is available in 5.12 kilowatt-hour (kWh) and it can be connected 32 in parallel, which allows flexibility in design and means that you can start small and add more batteries as your energy needs grow. The battery is also wall-mounted, providing an ultra-thin wall hanging and flexible solution to limited installation space, and restricted load-bearing customers.


PowerBase X1 is a high-quality, reliable, and safe battery energy storage system that provides your home with the security and freedom to keep the lights on, whenever you need it.
