Pylontech FH3X-10K-HY-3P-25

CEC listing: FH3X-10K-HY-3P-25 (AS4777-2 2020)

A 25.6 kWh home battery — medium home size, the 20–30 kWh band.

Installed in Perth, after rebates: ~$17,374; Typical estimate — your own quote will vary
WA Battery Scheme rebate: Depends on your inverter; The scheme needs a Synergy-approved inverter — we don't know yours
Usable capacity: 25.6kWh; Medium home size — the 20–30 kWh band

Also CEC-registered as 3 other configurations

PYLONTECH lists this exact 25.6kWh configuration separately per compatible inverter pairing on the CEC register. These are the same physical battery — grouped here by pairing rather than shown as separate products.

What we can tell you

Read from the figures on this page. No review written yet.

25.6 kWh sits in the medium home band (20–30 kWh).
It is CEC-approved, which is a condition of both the federal STC discount and the WA Battery Scheme.
We can't score it: a value score needs a price and full specs, and without them any number would be guesswork.

Key specs, in plain terms

The numbers that matter for a home. The full datasheet is below.

Usable capacity How much energy it stores for you to use: 25.6kWh
Round-trip efficiency How much of the energy you store comes back out: 98%
Depth of discharge How much of the battery you can actually use: 90%
Warranty 80% of capacity guaranteed at the end of it: 10yr
Battery chemistry Lithium iron phosphate — the long-cycle-life type: LFP

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$5,666
You’d pay about: $17,374

The WA Battery Scheme (up to $1,300) needs a Synergy-approved inverter and VPP enrolment. We don't know which inverter you'd pair this with, so it isn't deducted above — ask your installer. STCs assume about $39.9 a certificate. Estimates only; your quote will vary.
