About ESY SUNHOME
What is the ESY SUNHOME battery?
The ESY SUNHOME HM6 is a single-phase, all-in-one home battery. A 6 kW hybrid inverter sits on top of a stack of 5.12 kWh lithium iron phosphate (LFP) battery modules, on a floor-standing base. One stack takes one to six modules, so capacity runs from 5.12 kWh to 30.72 kWh.
The HM6 is the main ESY model in Sunbridge quotes. Our package uses all six modules: 30.72 kWh nominal, listed at 29.184 kWh usable on the Clean Energy Council approved battery list. It has two solar inputs rated for up to 8 kW of panels, a grid connection, and a separate backup output that can be wired to selected circuits.
ESYsunhome is a Shenzhen company founded in 2018. It grew out of battery management system work its founder started in 2004. The HM6 launched in January 2023, with bulk shipments then heading to its Sydney branch. In Australia, the warranty is provided by ESY SUNHOME AUSTRALIA PTY LTD in Greenacre, NSW.
All-in-one design
Battery, inverter and energy control are combined within a single, streamlined home unit.
Space-efficient format
A compact footprint is designed for homes with limited installation space.
Everyday solar use
The system is positioned around practical solar self-consumption and household backup.

In Sunbridge’s eyes
ESY SUNHOME review: an installer’s view
ESYsunhome was founded in Shenzhen in 2018, growing out of battery management system work its founder began in 2004. The all-in-one HM6 launched in January 2023, and ESY SUNHOME Australia, in Greenacre NSW, provides the local warranty. It’s a newer name here rather than an established one, so the pitch isn’t heritage; it’s an integrated battery-plus-inverter unit that keeps installs tidy and the price sharp.
- True all-in-one stacks , the 6 kW HM6 or 9.9 kW HM10 on single-phase, the HM10-H or HM15 on three-phase.
- Single-phase stacks of 5.12 kWh modules to 30.72 kWh; three-phase high-voltage modules to 94.86 kWh rated.
- A separate backup output for selected circuits, and IP66 enclosures for outdoor sites.
- Value-oriented pricing against the tier-one all-in-ones, with a 10-year Australian warranty that requires the system to stay online.

What size ESY SUNHOME battery do I need?
Start with the energy your home uses between sunset and sunrise. Your retailer bill, smart meter data or solar app shows it in kWh. Choose a battery whose usable capacity covers that, plus any growth you expect from an EV or electric hot water. The site inspection confirms the size before you commit.
Our ESY single-phase package is the HM6 with six 5.12 kWh modules. That is 30.72 kWh nominal and 29.184 kWh usable on the Clean Energy Council list. Six is the most one HM6 stack takes, and ESY's manual says the HM inverter does not support parallel operation, so this is the largest HM6 system. The 6 kW inverter, not the battery size, sets how much power you can draw at once. The full stack measures 600 × 305 × 1,878 mm and weighs 343 kg. ESY's warranty covers 129.0 MWh of throughput at this size. If you need more power on a single-phase supply, we also quote the HM10 with the same six-module stack. Three-phase homes are quoted on the HM10-H or HM15 with ESY's larger high-voltage modules.

| 30.72 kWh | 29.18 kWh | Single-phase or Three-phase | $6,997.53 | View the quote |
Can I add a ESY SUNHOME battery to my existing solar?
It can be. ESY's own support notes describe the HM6 running beside a separate solar inverter, with a current sensor (CT) on that inverter's output cable. Your existing panels and inverter stay in place, and the HM6 adds its own inverter for the battery. We confirm compatibility, switchboard space and network rules at the inspection.
- Your current solar inverter stays connected. A CT clamped on its output cable lets the HM6 see what your panels produce. ESY's CT meter is included in every ESY package we quote.
- The HM6 also has two MPPT solar inputs for new panels, rated for up to 8 kW of solar in total.
- On a three-phase supply, the HM6 connects to one phase, which ESY confirms in its FAQ. For battery power across all three phases, we quote the three-phase HM10-H or HM15 instead.
- Your network's connection rules, including any export limit, apply to the combined solar and battery system. We check them as part of the design.
- If your old inverter is near the end of its life, removal and disposal is a priced option in our quotes.
What does the ESY SUNHOME price include, and what costs extra?

ESY SUNHOME HM6 pros and cons
What we tell customers before they choose ESY SUNHOME.
Pros
- All-in-one stack. The inverter, battery modules and base form one unit, so there is no separate battery cabinet to mount.
- LFP cells rated for at least 6,000 cycles at 25°C to 70% state of health, according to ESY's datasheet.
- Quiet. The HM6 uses natural cooling, and ESY rates its noise at 25 dB or less at 1 m.
- Built for outdoor sites. The enclosure is IP66 and rated to operate from -25°C to 60°C.
- Quick changeover. ESY rates the switch time to the backup output at 20 ms or less.
- Local warranty support. ESY's Australian company provides a 10-year warranty that guarantees at least 70% of available capacity for 120 months, within a 129.0 MWh throughput limit for the 30.72 kWh stack.
Cons and things to check
- No room to grow. Six modules is the HM6 maximum, so a 30.72 kWh system cannot be expanded. ESY's warranty also only allows added modules within the first year after installation.
- 6 kW is the total output. ESY states the Australian HM6 delivers 6,000 W in total across home and backup loads. Its manual also limits single motor loads on the backup output, such as air conditioners, to 2.2 kVA each.
- The warranty depends on staying online. ESY's Australian terms require a constant internet or 4G connection, and say a lost connection can affect warranty rights. Claims must be lodged within one month of a fault being diagnosed.
- Placement takes planning. The 30.72 kWh stack is 1,878 mm tall and weighs 343 kg. It needs solid, flat ground, clear space around it and shade from direct sun, and ESY's datasheet shows derating above 45°C.
- Newer brand in Australia. The HM6 arrived here in 2023, so its local track record is shorter than longer-established battery brands.

FAQ
Frequently asked questions
Often, yes. The HM6 can run beside your existing solar inverter, using a CT sensor on that inverter's output so it can see your solar production. We check your inverter, switchboard and network rules at the inspection before confirming the design.
Both are single-phase all-in-one systems. They use the same 5.12 kWh modules, stack one to six modules and accept up to 8 kW of solar. The HM5 has a 5 kW inverter and the HM6 has a 6 kW inverter. Sunbridge quotes the HM6.
The Clean Energy Council list shows 29.184 kWh usable for the six-module ESYSUNHOME 30KWH+ battery. ESY's FAQ says the default discharge cutoff is 15% state of charge. After reaching it, the battery recharges to 35% from solar before it discharges again. The cutoff can be changed in the app, so daily usable energy depends on the settings.
Yes. In October 2026 we checked the Clean Energy Council lists published by the Clean Energy Regulator. The HM6 inverter (6 kW) and the ESYSUNHOME 5KWH+ to 30KWH+ batteries were listed. Listings carry expiry dates, so we recheck them for every quote.
Yes. ESY confirms the single-phase HM6 can connect to one phase of a three-phase supply. Its backup output is then single-phase. For battery power across all three phases, we quote ESY's three-phase HM10-H or HM15.
Yes. ESY's Australian warranty terms require the system to stay online by internet or 4G, and say a lost connection can affect warranty rights. The warranty guarantees at least 70% of available capacity for 120 months from installation, within a 129.0 MWh throughput limit for a 30.72 kWh system. Your Australian Consumer Law rights apply as well.
Outdoors is allowed, but ESY's manual says not in direct sunlight. The stack stands on solid, flat ground against a wall, with at least 600 mm clear in front and 800 mm above. Garage installs are an option in our quotes, priced with a bollard and a smoke alarm.
One stack takes one to six 5.12 kWh modules, from 5.12 kWh to 30.72 kWh. Our packages use six modules, which the Clean Energy Council list shows as 29.184 kWh usable.
