Solplanet Battery Review 2026: Ai-HB, AP-H and AP-L Specs, Price

Solplanet is the Australian brand of AISWEI, a Chinese inverter maker, and its home batteries are modular lithium iron phosphate (LFP) stacks: the Ai-HB G2 and AP-H high-voltage lines for three-phase hybrid inverters, and the AP-L and Ai-LB-G3 low-voltage lines for single-phase hybrids. They are usually quoted by budget-focused installers and online retailers as a cheaper alternative to Sungrow, BYD or Dyness. This review is based on manufacturer documentation, warranty terms, published pricing and owner/installer feedback; Solar Cobber did not test the product and was not paid by the manufacturer. Everything below was checked in November 2026, and it separates what the datasheets and warranty say from what owners report.

What it is and how it works

Solplanet batteries are DC batteries that sit behind a Solplanet hybrid inverter, which also runs your solar panels. They do not have a built-in inverter, so the battery and inverter must come as a matched pair from Solplanet’s compatibility list.

The company (AISWEI Technology Co., Ltd) is headquartered in Shanghai and makes its batteries at Yangzhong in Jiangsu province. In Australia the importer is AISWEI Pty Ltd, ABN 18 635 068 218, at Level 40, 140 William Street, Melbourne, with a service line on 1300 986 964, according to Solplanet’s Australian warranty document. SolarQuotes says AISWEI was previously part of the SMA group through Zeversolar, and that Solplanet-branded string inverters were first approved by the Clean Energy Council in early 2020, with hybrid inverters following in mid-2021.

The batteries come in four lines:

The “A” and “B” Ai-HB series matter. The older A series (CEC certificate BAT-468) uses a 90% depth-of-discharge rule, so a 20.48 kWh nominal stack lists 18.43 kWh usable. The newer B series (BAT-767, approved 29 January 2026) lists usable equal to nominal, so the same eight modules list 20.48 kWh. Ask your installer which series is on the quote, because 11% more usable energy for similar hardware cost changes the price per kWh.

The video above is Solplanet’s own installation walkthrough for the Ai-HB G2 high-voltage battery. It is a manufacturer video of about four minutes, published a few years ago, so treat it as a look at how the modules stack and connect, not as independent evidence of performance.

Specs that matter in Australia

Capacity and the federal discount. The discount is calculated on usable kWh, so the CEC-listed usable number is the one to use, not the nominal label. The chart shows the range each line offers.

	Smallest listed	Largest listed
AP-H	10.24 kWh	51.20 kWh
Ai-HB B series	5.12 kWh	20.48 kWh
Ai-HB A series	6.91 kWh	18.43 kWh
AP-L	13.92 kWh	16.08 kWh
Ai-LB-G3	5.12 kWh	5.12 kWh

The AP-H goes up to 51.2 kWh per tower, far above the other lines, while the Ai-LB-G3 is listed only as a single 5.12 kWh module that installers stack.

Power is the quiet limit. The Ai-HB B datasheet gives 2.56 kW rated power for the 5.12 kWh Ai-HB 050B and 10.24 kW for the 20.48 kWh Ai-HB 200B, with a maximum discharge of 12.29 kW at the top size. That is about 0.5 kW per kWh, which means a small stack cannot deliver much blackout power by itself. Solar Cobber calculation: at the rated 2.56 kW a 5.12 kWh Ai-HB 050B takes 2 hours to move its full capacity, but pairing a 10 kW three-phase inverter with a 7.68 kWh stack limits the battery to about 3.84 kW. Check the battery’s kW, not just the inverter’s.

Heat, cold and weather. The Ai-HB B datasheet rates charging at 0 to 50 °C and discharging at -20 to 55 °C, with IP65 protection and natural convection cooling. The AP-L and Ai-LB-G3 are IP66 with the same passive cooling. These are floor-standing batteries, so put them in shade out of the afternoon sun. Our guide to how long solar batteries last explains why heat matters for LFP.

Single and three phase. The high-voltage Ai-HB and AP-H lines pair with the three-phase H-T2 and H-T3 hybrids (5, 8, 10 and 12 kW). Solplanet’s datasheet says those inverters support 100% unbalanced three-phase output on backup. Single-phase homes use the low-voltage AP-L and Ai-LB-G3 batteries with the H-S2 (3 to 6 kW) or SH-series hybrids; see our guide to single vs three phase power.

Clean Energy Council status. The Clean Energy Council (CEC) approved batteries list on 14 November 2026 showed all five Solplanet certificates. Four expire on 31 December 2027; the older Ai-HB A series (BAT-468) expires on 7 January 2027, so confirm an A-series model is still listed on your install date. We did not check the CEC inverter list.

Price in Australia

We found no published installed price for Solplanet batteries from SolarQuotes, Solar Choice or CHOICE, so there is no independent installed range. The only dated prices we could open are hardware-only listings at PowerBay, an Australian online retailer that sells Solplanet-branded batteries, checked on 14 November 2026. PowerBay does not say whether the listed price already includes the federal discount, and the prices exclude installation, so treat them as hardware prices.

The listings name the older A-series model numbers, so the high-voltage price per usable kWh is higher than it would be for a B-series stack with the same nominal size. The same retailer lists hybrid inverters at A$1,499 (5 kW single phase), A$2,199 (10 kW single phase), A$1,999 (5 kW three phase) and A$2,399 (10 kW three phase), plus a high-voltage battery combiner box at A$489.

HV 9.21	A$586

The low-voltage range costs roughly A$390 to A$420 per usable kWh and the older high-voltage stacks A$540 to A$586, so the cheapest Solplanet hardware is the low-voltage line.

How the federal discount applies

The federal Cheaper Home Batteries Program issues small-scale technology certificates (STCs) for the first 50 kWh of usable capacity, with a 6.8 STC factor for installs from 1 May to 31 December 2026 and 5.7 from 1 January 2027, as in our federal battery rebate guide and state-by-state battery rebates. The first 14 kWh earns 100%, 14 to 28 kWh earns 60% and 28 to 50 kWh earns 15%.

Solar Cobber calculation, assuming A$37 per STC (our other reviews use the same figure) and rounding certificates down:

• May to Dec 2026 (6.8 factor)
• From 1 Jan 2027 (5.7 factor)

	May to Dec 2026 (6.8 factor)	From 1 Jan 2027 (5.7 factor)

20.48 kWh	A$4,477	A$3,737
30.72 kWh	A$5,735	A$4,810

The discount on an 18.43 kWh Ai-HB 200A stack falls by about A$700 on 1 January 2027, so the step-down is worth planning around if you are choosing between a December and a January install. If PowerBay’s A$9,959 is before the discount, the 18.43 kWh stack nets to about A$5,780 for hardware at 2026 rates, before inverter, combiner box and installation. Because we could not confirm that basis, check with the seller.

Warranty: the fine print

Solplanet’s Battery Factory Quality Warranty Terms for Australia, version 1.8 dated 20 September 2026, cover the Ai-LB, Ai-HB, AP-H and AP-L lines. Version 1.8 removed the earlier 5-year standard plus 5-year extended structure and now lists a flat 10 year standard period. The main terms:

• Term: 10 years, starting from the earlier of first installation completion or 6 months after shipment from AISWEI.
• Performance: retains 70% of Usable Energy, or reaches the Minimum Throughput Energy in the model table, whichever comes first, if operated to specification.
• Throughput: 3.0 MWh per usable kWh for the Ai-HB A and B series (for example 61.44 MWh for the 20.48 kWh Ai-HB 200B) and about 2.7 MWh per usable kWh for AP-H, AP-L and Ai-LB-G3 (for example 138.24 MWh for the 51.2 kWh APH5.0-S10).
• Reporting: the warranty conditions list reporting a fault or warning within one week, and the procedure asks for a written defect notice within 14 days.
• Installer: must be a skilled person or third-party installer certified by AISWEI.
• Exclusions: include failure to follow the manuals or standards, including operating-temperature overrange (the document gives “-10 to 50”), modifications, and incompatibility with the rest of the system.
• Remedy: at Solplanet’s discretion: remote help, factory repair, on-site service or a replacement of equivalent value, including a refurbished unit. A repaired or replaced unit gets the remaining warranty, with a minimum of one year.
• Who to call: AISWEI Pty Ltd on 1300 986 964 or service.au@solplanet.net. Solplanet may change the terms by publishing them on its website.

Two points stand out. The “-10 to 50” temperature wording is narrower than the datasheet’s -20 to 55 °C discharge range, so ask which governs on a frosty or very hot site. And the throughput cap bites if you cycle hard: 2.7 MWh per kWh over 10 years is 0.74 full cycles a day, while 3.0 is 0.82.

Solplanet Ai-HB (A and B)	0.82
BYD Battery-Box Premium	0.82
Solplanet AP-H, AP-L, Ai-LB-G3	0.74

For a typical home that cycles once a day on a time-of-use tariff, Solplanet’s AP-H, AP-L and Ai-LB-G3 allowances would run out before year 10 (a cap of 0.74 cycles a day against one cycle), while Dyness and ESY Sunhome allow a daily cycle. Homes that only partly use the battery each day, for example those with small evening usage, are less likely to hit the cap. Our what size solar battery do I need guide can help you size it so it is not cycled hard.

What owners and installers report

Praise. SolarQuotes lists 30 ratings for Solplanet inverters, averaging 4.6 out of 5 (checked 14 November 2026), with 26 five-star ratings. That is an inverter page, not a battery page, and SolarQuotes flags that VoltX Energy offered an incentive for at least one review. The same page lists the IP66 rating and affordability as pros, and no display on the unit and limited app features as cons. It says reviewers report paying A$5,000 to A$9,100 for a 6.6 kW solar system with a Solplanet inverter. We found no SolarQuotes battery rating for Solplanet.

Complaints. The recurring themes in what we could read are about software and support, not cell failures:

• App and firmware. Excerpts from a long Whirlpool Forums thread about VoltX Energy systems with Ai-HB G2 batteries describe the app going offline after a firmware update, battery stacks missing from the app, state of charge showing as 0, and an owner downgrading firmware. We could not open the thread directly, so we are relying on search-engine excerpts and the dates are unclear.
• Support speed. The same excerpts mention emailed replies from the retailer and Solplanet taking several days.
• Local integrations. A GitHub issue for the open-source evcc project reports that newer AI-Dongle firmware broke an existing integration, although the dongle’s local HTTP API itself works.

We found no ACCC product-safety recall for Solplanet batteries, but we could not query the database directly. Independent test coverage is thin: we found no Canberra battery test or CHOICE result for the brand.

Solplanet vs alternatives

Rival figures below come from our reviews of each product, using the same row headings.

These prices are on different bases (retail hardware before discount against SolarQuotes prices after the discount), so do not compare the last row directly; get like-for-like quotes. Choose a Sungrow SBR if you want a bigger local track record and a warranty with no cycle limit for normal home use. Choose a BYD Battery-Box Premium if you want a long-established modular battery that works with several inverter brands. Choose a Dyness if you want a higher throughput allowance and a battery that can run from a Solplanet or other inverter. Choose Solplanet when the quote is meaningfully cheaper and you accept the shorter record.

Questions to ask your installer

• Which Solplanet line and series is quoted (Ai-HB A, Ai-HB B, AP-H, AP-L or Ai-LB-G3), and what is its CEC usable kWh and listing expiry?
• Which exact Solplanet hybrid inverter is on the quote, and is that battery and inverter pair on the July 2026 compatibility list?
• How many kW of backup will the stack deliver at this size, not just the inverter rating?
• How many STCs have you claimed, at what factor, and what happens to my price if installation slips past 1 January 2027?
• Which warranty version applies on my installation date, and will you register the system on the Solplanet app and portal?
• How does the one-week fault reporting rule work in practice, and who do I call when the app goes offline?
• Are you certified by AISWEI to install the battery, as the warranty requires?
• If I join a virtual power plant (VPP), will it count against the throughput cap?

FAQ

Is Solplanet a good battery brand?

Solplanet is a low-cost brand with solid paper specifications and a 10 year warranty, but a short Australian track record. SolarQuotes rates its inverters 4.6 out of 5 from 30 ratings, and we found no independent battery rating or test result.

Where is Solplanet made and who owns it?

Solplanet is the brand of AISWEI, a Shanghai-headquartered company that makes its batteries in Yangzhong, Jiangsu, China. The Australian importer is AISWEI Pty Ltd in Melbourne. SolarQuotes says AISWEI was once part of the SMA group via Zeversolar.

How much does a Solplanet battery cost?

Online hardware prices on 14 November 2026 ranged from about A$390 to A$586 per usable kWh at PowerBay, before installation. We found no published installed range, so get quotes and ask whether the federal discount is included.

What is the Solplanet battery warranty?

The Australian warranty (version 1.8, September 2026) is 10 years, retaining 70% of usable energy or a minimum throughput of about 2.7 to 3.0 MWh per usable kWh, whichever comes first. Solplanet may repair, replace with a refurbished unit or provide on-site service.

Which inverters work with Solplanet batteries?

Solplanet’s own hybrid inverters: the three-phase ASW H-T2 and H-T3 for the high-voltage Ai-HB and AP-H, and single-phase H-S2 or SH models for the low-voltage AP-L and Ai-LB-G3. Solplanet says its batteries must only be used with inverters it names.

Are Solplanet batteries approved for the federal battery discount?

Yes, on 14 November 2026 the Clean Energy Council list showed Solplanet batteries under five certificates. The newer lines run to 31 December 2027, and the older Ai-HB A series (BAT-468) runs to 7 January 2027.

Does Solplanet work with a blackout backup?

Yes, the hybrid inverters offer backup output with a switchover under 10 ms according to Solplanet datasheets, but the usable power depends on battery size and the inverter, so confirm how many kW of backup your configuration supports.
