Following the successful launch of the EP900 just months ago, BLUETTI is once again making waves in the energy storage sector with the upcoming EP800 model.

While home battery backups have gained popularity for reducing energy costs and carbon footprints, reliance on solar power during daylight hours and grid availability poses limitations. Grid-tied or off-grid solar systems with big batteries allow you to store excess clean energy and maintain power in the case of grid outages or power blackouts. BLUETTI, a top player in the energy storage field, is set to bring out another battery solution–EP800 in September this year. What is it exactly? And how does it differ from its predecessor – the EP900, which uses the same B500 battery packs? Let’s find out.

What is the BLUETTI EP800 & B500?

The BLUETTI EP800 & B500 is a 7,600W modular home energy storage system (ESS), featuring 9,000W PV input and scalable capacity from 9,920Wh to 19,840Wh. Similar to the EP900, it is widely compatible with existing or future solar systems for energy bill saving and blackout preparedness.

Besides their output performances, the main difference between EP800 and EP900 lies in their ability to connect to the utility grid. The former is a pure off-grid system, while the latter also supports on-grid connection, whose installation therefore could take several months with time-consuming paperwork and inspection processes.

With an easy and quick installation of a few hours, the EP800 is a blessing for those in urgent need of complete battery systems to pair with their solar setups.

Key features of the BLUETTI EP800 energy storage system

1. Flexible capacity from 9,920Wh to 19,840Wh
The EP800’s modular design allows users to tailor their energy storage capacity to their specific needs. By choosing two to four B500 battery packs, each providing 4,960Wh, you will have a customised capacity ranging from 9,920Wh to a maximum of 19,840Wh. According to a recent study showing that a small 10kWh solar ESS can meet backup needs for a 3-day outage in nearly all US counties, that energy storage could get you through a blackout lasting almost six days, or two days without solar power.

2. Powerful performance: 7,600W output and 9,000W solar input
The EP800 system delivers up to 7,600W power for the whole household. It can run both your 120V TVs and 240V pumps with ease. With dual MPPT charge controllers inside, the EP800 can maximise solar input at 9,000W, allowing you to easily reach power independence by solar. This also makes it an ideal choice for small businesses, farms and workplaces that are remote from the grid power.

3. Wide compatibility with solar panels
Whether you already have installed solar panels or plan to do so in the future, the EP800 seamlessly integrates into your solar panels with its DC-coupled connectivity. Generally, there are two types of electrical systems to connect a PV system to storage batteries, DC coupled and AC coupled. Rather than converting solar-generated DC power back and forth to AC power with unnecessary energy losses, a DC coupled system converts the DC solar power to AC only once that your home appliances use, making it more energy efficient.

4. Easy and quick installation: Indoor or outdoor
As an off-grid energy storage unit, the BLUETTI EP800 can be set up in a few hours with simple hook and screw steps. Even DIYers or homeowners interested in electricity can handle it. Instead of being mounted on the wall, it can be stacked vertically without damaging the wall or taking up too much space. With a NEMA 4X rating and quiet operation at less than 50dB, you can easily install it indoors or outdoors. Plus, BLUETTI offers an optional global installation team that can handle all the on-site work for you.

5. Durable design with 10 years warranty
Designed to be stylish and long-lasting, the EP800 is encased in a durable and corrosion-resistant aluminum alloy. It boasts a NEMA 4X rating for water, dust, and corrosion resistance. Using the safest LiFePO4 batteries available, the EP800 could have a at least ten-year lifespan. It also comes with an advanced BMS that prevents short circuits, overcharging and other potential hazards. To ensure hassle-free use, BLUETTI also backs it with a ten-year warranty.

6. Intelligent system: smart operation and easy control
The EP800 can adapt to varying weather conditions, regulating its discharging processes based on ambient temperature through its advanced thermal management technology. With the BLUETTI app, you can monitor system performance, track your power consumption and generation, and adjust settings remotely via WiFi or Bluetooth connectivity from anywhere at any time. Moreover, OTA updates are available for added convenience.

How to get the most out of the EP800 energy storage system

Get the power back in 20ms
The BLUETTI EP800 provides a stable and seamless power supply during emergencies and power failures. It takes less than 20ms to switch from grid power to its battery, providing stored power for all your essential appliances, large and small, such as refrigerators, dryers, water pumps, electric stoves, lights and medical equipment. An EP800 with two battery packs can power an average refrigerator for four days, or eight days with four packs. That means you can rest easy knowing that those steaks and ice creams will never again end up in the trash.

Enjoy power freedom
The EP800 could connect to solar panels for a maximum of 9,000W of solar charging. Even during power outages, there will be enough power in reserve to run your entire home. Two B500 packs, 9,920Wh of energy, equivalent to 3.3 hours of use of 2500W air conditioner, 140 hours of lighting (60W), and uninterrupted network connection. If you have a large family or experience a prolonged power cut, four B500 batteries will provide up to 19,840Wh of power, giving you peace of mind that your family will still live comfortably. This stronger battery system could power your 200W freezer for 84 hours, 500W washer for 33.5 hours and 2,000W oven for 8 hours. For others, power failures may mean disaster and hardship, with stinking piles of laundry and limited use of electronics. However, with the EP800 backup system in your home, a blackout is nothing more than a chance to show off your independence from the grid.

Benefit you and the Earth
The BLUETTI EP800 is an eco-friendly and quiet backup power source that runs on renewable energy instead of the fossil fuels of traditional generators. Unlike gas-powered generators that emit harmful gases into the environment when used, it produces no emissions or noise pollution, making it an environmentally friendly option for powering homes or businesses.

The BLUETTI EP800 energy storage system will be available on September 15 with a debut price starting from $5999.
