3 FAQs About Home Battery Storage

ZRGP energy storage system can reduce your fuel bills and carbon emissions, especially if you already have home solar panels. Residential Energy Storage Systems offer considerable energy and cost-saving benefits such as solar battery storage, peak shifting, grid services, and battery storage backup.

Here are some of the most frequently asked questions about energy storage.


 1、How do batteries differ?

There are four main types of batteries namely lithium-ion, lead-acid, flow, and saltwater. Lithium-ion batteries are generally the most suitable for homeowners, as they’re lightweight, compact, and typically have a longer shelf life than other battery technologies. They also have a higher depth of discharge, meaning you can tap into more of your battery’s capacity.

All of ZRGP’s BESS, modules use lithium iron phosphate to ensure the safest, most efficient, and cleanest product to power your life.


 2、What are the benefits of energy storage systems?

Coupled with your home solar system, the ZRGP PowerBase Max-X energy storage system gives you greater control over your energy usage and bills and helps you get the most from your solar investment.

  • Reduce Electricity Bills

Adding an energy storage system to your home can effectively reduce the electricity bill. Installing an energy storage system will keep the total power consumption below a specified value. With on-site storage, you can charge your batteries whenever electricity rates are at their lowest (during off-peak hours or with your free solar energy).

  • Maximize Self-Consumption

The energy storage system can perfectly suit commercial and residential uses. During the daytime, the system can collect and store energy, which can be used at night whenever needed. Property owners are provided with the most efficient use of solar energy at home, including grid independence, increased self-consumption, and reduced electricity bills.

  • Emergency Power Backup

Don’t worry about the sudden power failure. Residential energy storage solutions integrated with solar panels can ensure energy backup. The backup power system is used to provide energy when the primary source fails for the 24/7 power supply.


 3、Can I Go off-grid?

Installing battery storage in your home does not necessarily mean that you can disconnect completely from the electrical grid. While it’s possible to go off the grid, the number of solar panels and the amount of battery storage you may need to invest in could mean it’s not financially viable.

Generally speaking, going off-grid is not practical for the average urban consumer because:

  • It might be difficult to store enough energy to reliably cover your use during cloudy days in winter;
  • You would not be able to sell any surplus energy back to the grid;
  • There are likely to be significant extra costs (e.g. special additional equipment like the installation of an air-conditioning system) for the battery.

Introducing ZRGP PowerBase X1 – Wall Mounted Home Battery System

PowerBase X1 provides an ultra-thin wall hanging and flexible solution to limited installation space, and restricted load-bearing customers.

The battery is a lithium iron phosphate battery system, which can be used to provide safe, reliable, and stable energy for various equipment. And it can be widely used in household energy storage, industrial and commercial energy storage, and other fields.

The flexibility of ZRGP PowerBase X1 can power homes for longer periods, granting access to a greater amount of on-site, clean energy available day and night. Multiple batteries are allowed to be connected in parallel to expand capacity and power to meet the requirements of longer power supporting duration and higher power consumption.

PowerBase X1 features ZRGP’s industry-leading warranty of 8000 times cycle life/10 years as well as compatibility with 16 world-famous inverter brands. The built-in battery management system manages and monitors battery voltage, current, temperature, and other information. In addition, the BMS can help extend cycle life by balancing the battery during charging and discharging.


By communicating with the battery management system, PowerBase X1 with Smart Cloud monitoring and control system enables users to customize system behavior or implement remote firmware updates for easy day-to-day use and maintenance. And equipped with a monitoring LED display, can provide essential data visualization, more convenient for users to observe the operation of the system.

Production of ZRGP PowerBase Mate

​A big day for ZRGP as our PowerBase Mate Energy Storage System was ready to leave the warehouse.


ZRGP PowerBase Mate

As a ZRGP UL9540A – certified BESS home energy storage system, Mate is our most classic product, featuring a modular LV design, LFP cells, 8000 cycle life, and scalability to meet the needs of businesses and homes of all sizes.

• Between 2 to 8 battery modules can be used in a single stack to give 10.24 to 40.96kWh usable capacity;

• Up to 15 stacks can be connected in parallel to give a maximum 614.4kWh usable capacity;

• Additional modules or parallel stacks can be added at any time to increase capacity.


Battery Cell

ZRGP energy storage systems adopt A-Grade LFP Cells featuring high energy density, highest-level safety, longest service life. And the standardized square batteries are easy to stack and splice.


  • Service life: After 8000 times of charge and discharge, it can maintain no less than 80% of the battery capacity
  • High energy density: Can reach more than 135kWh/kg
  • Long service life: The service life of a single cell is up to 8000 charge-discharge cycles
  • Charge and discharge rate: Up to 2c strength
  • Safety: Even if it is forced to cause an internal short circuit or the possibility of rupture or fire is extremely low, the battery has passed the needle penetration test

The laser welding process ensures the battery connection is reliable and the module has high reliability and long service life.


Battery Module

Each module of PowerBase Mate system built-in BMS, and ZRGP energy storage systems are designed as a three-layer energy management system. Your battery system will get strong protection, high reliability, and long cycle life.


Professional BMS:

  • Temperature management: Single-cell temperature control, temperature difference control between cells balance management: maintain the consistency of related parameters between cells
  • Protection function: Overcurrent/overvoltage/undervoltage/overtemperature/communication fault protection
  • Troubleshooting: Determine the type of battery fault and handle it accordingly
  • Communication function: CAN bus, RS485


Aging test on lithium battery pack

The first role is conducive to the stability of the performance of the lithium battery pack. The second is to select the consistency of the lithium battery pack after aging for a period of time.

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.
