What the numbers mean for your home

Up to 20 kW output per unit

High output means the system can run heavy three-phase loads — ducted air conditioning, pumps, workshop equipment — directly from the battery, not just light circuits.

14.7–51.6 kWh, expandable to 154.8 kWh

A single unit covers large homes; paralleling up to three units suits small businesses and farms that need very large, whole-property storage.

Up to 40 kWp solar input

You can connect a very large solar array per unit, capturing more energy across the day and charging the large battery quickly.

Usable energy and the 70% warranty

Bluetti rates the EP2000 by capacity (7.35 kWh per B700 pack) and backs it with a performance warranty: over 10 years, each pack retains at least 70% of its usable energy capacity, or until it reaches its guaranteed throughput, whichever comes first.

VDE-AR-E 2510-50 certification

This is a stringent German standard for home storage systems. Certification to it signals the system meets a high bar for safety and grid compatibility.

Three-phase whole-home backup

In a three-phase home the battery can back up loads across all three phases during an outage, so three-phase appliances keep working — not just single-phase power points.

A deeper look at the technology

Serious power for large homes and business

The EP2000 is built for properties that need real power. A single unit delivers up to 20 kW of output and up to 51.6 kWh of storage with 2–7 B700 packs, and you can parallel up to three units for a maximum of 60 kW and 154.8 kWh. With up to 40 kWp of solar input per unit, it suits large homes, off-grid properties, farms and small businesses.

The HV800 voltage controller manages the high-voltage battery stack, and the system runs on-grid or off-grid for genuine whole-property energy independence.

Three-phase backup that keeps the property running

As a true three-phase system, the EP2000 can back up the whole property across all phases during an outage, with a switchover time under 10 milliseconds. That keeps three-phase appliances — pumps, ducted air conditioning, workshop machinery — running, not just a handful of circuits.

You can monitor and control the system through the Bluetti app over USB, Wi-Fi or Bluetooth, with an integrated EMS coordinating solar, storage and loads.

Safety, certification and warranty

The EP2000 uses LFP (lithium iron phosphate) battery packs — the most thermally stable mainstream lithium chemistry — and is certified to the German VDE-AR-E 2510-50 standard with an IP65 rating.

It is backed by a 10-year warranty that guarantees each B700 pack retains at least 70% of its usable energy capacity over the term, or until it reaches its guaranteed energy throughput, whichever comes first.

Key terms explained

Shopping for a home battery means wading through technical jargon. Here is what the most important terms on this page actually mean.

kW vs kWh

A kilowatt (kW) measures power — how much the system can deliver at any instant. A kilowatt-hour (kWh) measures energy — how much it can store or deliver over time. A 10 kW / 20 kWh system can push 10 kW and hold 20 kWh, roughly enough to run a 10 kW load for two hours.

LFP (LiFePO₄)

Lithium iron phosphate, a lithium battery chemistry prized for thermal stability, safety and long cycle life. It is the preferred chemistry for residential storage.

Hybrid inverter

A single inverter that manages solar panels, the battery and the grid together, rather than needing separate solar and battery inverters.

High-voltage (HV) battery

A battery built from many cells in series to reach a high system voltage (often 400–800 V). Higher voltage means lower current for the same power, which reduces losses and can improve efficiency.

Depth of Discharge (DoD)

How much of a battery’s capacity you can safely use. 95% DoD means 95% of the rated capacity is usable; 100% means all of it.

Usable vs nominal capacity

Nominal capacity is the battery’s total energy on paper; usable capacity is what you can actually draw after the DoD limit. Always compare batteries on usable kWh.

Cycle life

The number of full charge-and-discharge cycles a battery can perform while staying within its warranty performance. Roughly one cycle per day of normal use.

Round-trip efficiency

The share of energy you get back out of the battery compared with what you put in. Higher efficiency means less energy lost as heat during storage.

C-rate (1C)

How fast a battery charges or discharges relative to its capacity. 1C means it can charge or discharge its full capacity in about one hour.

MPPT

Maximum Power Point Tracking — circuitry that constantly tunes each solar string to extract the most power. More MPPTs let panels on different roof faces perform independently.

Three-phase vs single-phase

Single-phase supply has one active wire and suits most smaller homes; three-phase has three and suits larger or all-electric homes with heavier loads. The battery must match your supply type.

Unbalanced load

In a three-phase home, when the three phases draw different amounts of power. A system that supports unbalanced loads can back up appliances even when the phases are uneven.

Backup / anti-islanding

Backup power runs your home during a grid outage. Anti-islanding is the safety function that stops the system feeding the grid during an outage, protecting line workers.

VPP (Virtual Power Plant)

A network of home batteries an energy provider can call on at peak times. Joining a VPP can earn you payments or credits for sharing stored energy back to the grid.

IP rating (e.g. IP65)

An Ingress Protection rating. The first digit is dust protection (6 = dust-tight), the second is water protection. An IP65/IP66 unit can be installed outdoors.

Rebates, payback and savings

Home battery storage can be eligible for government rebates and incentives, which change over time and vary by state and household. For a large system like the EP2000, the right rebate and a correctly sized design can have a significant impact on payback.

Sunbridge handles rebate guidance as part of the quote process: we check current eligibility, factor available incentives into your system design, and show you the expected payback based on your actual usage. See our battery rebate guidance for more, and we will confirm what applies to your address when you request a quote.

Installation and support by Sunbridge

Sunbridge designs every EP2000 system around your property rather than selling a fixed package. We start by analysing your electricity bills and smart-meter usage data to understand how and when you use power, then size the inverter, battery and any paralleled units to match.

Installation is carried out by accredited installers to Australian standards, including three-phase switchboard and backup configuration, commissioning and testing, and a full handover so you know how to use the Bluetti app. We also provide ongoing support and monitoring for the life of the system.

Warranty

The Bluetti EP2000 — including the EP2000 inverter, HV800 voltage controller and B700 battery packs — is covered by Bluetti’s EP2000 Limited Warranty for Australia.

It provides a 10-year product warranty and a performance warranty guaranteeing that, over ten years, each B700 battery pack retains at least 70% of its usable energy capacity, or until it reaches its guaranteed aggregate energy throughput, whichever comes first.

These are the manufacturer’s terms; your guarantees under the Australian Consumer Law apply in addition. Sunbridge confirms the warranty terms for your configuration and registers the warranty on your behalf as part of the installation.
