What we can tell you

Read from the figures on this page — no review written yet

13.8 kWh sits in the smaller home band (10–15 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: 13.8kWh
Round-trip efficiency How much of the energy you store comes back out: 92%
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

WA Battery Scheme eligibility

Conditional

Synergy SSL inverter pairing, VPP participation and state-rebate qualification for this battery. Rebate and STC amounts are shown in the pricing panel.

AC-coupled system: needs a gateway device on the Synergy SSL (e.g. SMA, Redback), or a same-brand inverter + battery pair (Sungrow or Fronius) for shared compliance. Without one, export is limited to 1.5kW and VPP/DEBS/rebate/loan are unavailable — and third-party gateways can struggle to meet compliance testing. Any later addition to an AC-coupled system triggers whole-of-site compliance, so for many homes replacing toward a hybrid (DC-coupled) inverter is the sounder path. AC vs DC coupling

CSIP-AUS compliant
Inverter must be CSIP-AUS compliant under the current WA framework.
Synergy SSL approved inverter
Needs pairing with a Synergy SSL approved inverter.
VPP activation ready
VPP activation requires a Synergy SSL approved inverter.
WA Battery Scheme rebate
Requires Battery Rewards participation under the current WA framework.
Synergy Battery Rewards
Requires a CSIP-AUS compliant system and reliable internet.
Interest-free loan
Not eligible for interest-free financing.

Under current WA rules, new rebate applications require VPP enrolment and CSIP-AUS compliance. How the scheme works · Estimate VPP earnings

Fault & error codes — iStore IS-BATT

Extracted from the installation manual

6 documented

Showing 6 of 6. The official install manual is the authoritative source — always confirm before acting.

3000criticalCall your installer
Manual (PDF)
Low battery DC input bus voltage
Likely cause
1. The DC bus voltage of the battery is low. 2. The battery DC switch is OFF. 3. The battery cables are not correctly connected.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Check the cable connections to the Battery-1/2 power control module by referring to the quick installation guide. 3. After checking that the battery power cables are correctly connected, turn on the battery DC switch, AC output switch, and inverter DC input switch in sequence. 4. If the alarm persists, contact your dealer or Technical support.

Manual (PDF)
Abnormal battery power control module
Likely cause
A major fault has occurred on the internal circuit of the battery power control module.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Turn on the battery DC switch, inverter AC output switch, and DC input switch. 3. If the alarm persists on the Battery-1/2 power control module (the battery fault indicator is steady on), contact your dealer or Technical support.

Manual (PDF)
Battery power control module fuse blown
Likely cause
The fuse of the battery power control module is blown.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch and wait for 5 minutes. 2. Replace the fuse of the Battery-1/2 power control module. 3. Turn on the battery DC switch, inverter AC output switch, and inverter DC input switch in sequence. If the alarm persists, contact your dealer or Technical support.

Manual (PDF)
Battery power control module reversely connected
Likely cause
The positive and negative terminals are reversely connected when the battery power control module connects to the inverter.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Check the cable connections to the Battery-1/2 power control module by referring to the quick installation guide. 3. After checking that the battery power cables are correctly connected, turn on the battery DC switch, AC output switch, and inverter DC input switch in sequence. 4. If the alarm persists, contact your dealer or Technical support.

Manual (PDF)
Battery power control module overtemperature
Likely cause
1. The installation position of the battery power control module is not well ventilated. 2. The ambient temperature is excessively high. 3. The battery power control module is abnormal.
What to do
1. Check the ventilation and whether the ambient temperature of the Battery-1/2 power control module exceeds the upper threshold. 2. If the ventilation is poor or the ambient temperature is excessively high, improve the ventilation and heat dissipation. 3. If the ventilation and ambient temperature are normal, contact your dealer or Technical support.
3005warning
Manual (PDF)
Battery power control module DC switch OFF
Likely cause
1. The DC switch of the battery power control module is OFF. 2. The DC bus cable to the battery power control module is disconnected.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Check the cable connections to the Battery-1/2 power control module by referring to the quick guide. 3.

Typical installed price, before rebates

WA Battery Scheme: Depends on your inverter
Federal STCs: −$3,711
You’d pay about: $8,709

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.
