Growatt Battery Compatibility (2026): Approved List, Protocols & Setup Codes

Most “Growatt compatible battery” pages you’ll find are a straight copy of Growatt’s own PDF — a brand list, a protocol column, and nothing else. That gets you halfway. The half that decides whether the system actually commissions is the column almost nobody explains: the Lithium Mode setup code the inverter needs for that specific battery. Right battery, right protocol, right wiring — wrong code, and the pack still won’t talk. This guide covers which batteries are approved for Growatt inverters, which protocol each one uses, and the setup code that goes with it.

Quick answer: Growatt runs an open battery ecosystem. Its hybrid inverters work with Growatt’s own Hope, ALP and AXE packs and with third-party LFP batteries from Pylontech, Dyness, Pytes, EG4, Raystech, Zetara, Topband, Enersys and Sacolar, over either CAN or RS485. Each approved battery has a matching Lithium Mode code (00–04) that must be set on the inverter — this is the step that most commissioning failures come down to. Growatt publishes these pairings per inverter model in its Approved Battery List (the matrix below is from version Growatt-LV48-0003, issued against the SPH 10000TL-HU family), and states that if a non-approved battery is used, it won’t be liable for communication faults. Always pull the list for your exact inverter model — brands carry over, codes don’t always.

Growatt Approved Battery List: Brands, Protocols and Setup Codes

Growatt is an open platform: you are not locked to Growatt-branded batteries. What you are locked to is the approved list — the specific model, the protocol, and the setup code that goes with it. The matrix below is Growatt’s official pairing table for the SPH 10000TL-HU family. Treat it as the template for how Growatt structures every list: the same brands recur across the range, but the Lithium Mode codes are assigned per inverter document, so confirm yours against the list issued for your model.

Per the Growatt Approved Battery List, version Growatt-LV48-0003, issued 5 November 2024 by Shenzhen Growatt New Energy, covering SPH 10000TL-HU-US(B) / SPH 10000TL-HU-US / SPH 10000TL-HU. Model coverage and codes change between document revisions — always check the current list for your exact inverter model before ordering.

The 3-Layer Growatt Pairing Check

“Will this battery work with my Growatt?” isn’t one question — it’s three, and they have to pass in order. Most guides answer only the first. Here’s the full check.

Layer 1 — Listed? (the model, not the brand)

Growatt’s approval is granted per model, not per brand. Pylontech is on the list — but that means US2000B, US3000C, US5000, Force L1/L2 and the other named models, not automatically whatever Pylontech released last quarter. The practical consequence sits in Growatt’s own note: the purchaser should confirm compatibility with the battery supplier, and Growatt will not be liable for failures caused by communication issues on batteries it hasn’t approved. If your model isn’t named, you’re carrying that risk yourself.

Layer 2 — Protocol? (CAN or RS485)

Growatt’s approved batteries split across two communication buses, and this decides your hardware. Pylontech, EG4, Raystech, Zetara and Enersys run over CAN. Dyness and Topband run over RS485. Pytes, Sacolar and Growatt’s own Hope packs are listed for either. CAN is generally the faster, more reliable handshake and is what most installers default to; RS485 typically needs more manual configuration. The two use different cable pinouts, so pick the protocol before you crimp anything.

Layer 3 — Setup code? (the one everybody skips)

This is the layer that separates a working system from a two-hour site callback. Every approved battery maps to a Lithium Mode code that has to be entered on the inverter: 00 for Dyness and most RS485 packs, 01 for EG4, Raystech, Zetara and Pytes-over-CAN, 02 for Enersys, 03 for Topband, 04 for Pylontech. Set the Battery Mode to Lithium, then set the Lithium Mode to the code for that specific battery. Get this wrong and the symptom is misleading — the wiring is right, the protocol is right, and the pack still reports no communication.

Supply-side note: the LFP batteries we supply ship with CAN/RS485 BMS for exactly this kind of open inverter. But installers keep telling us the same thing trips up commissioning: the protocol is right and the wiring is right, and the pack still won’t talk — because the Lithium Mode code wasn’t set to match that battery. It’s a two-minute setting that costs a return visit.

“No Communication” on a Listed Battery: How to Triage It

Search the installer forums and you’ll find the same thread over and over: an approved battery, wired to an SPH, refusing to hand off to the inverter. The fault is almost never the battery. Work the three layers in reverse — start with the cheapest thing to check, not the hardest.

Nine times out of ten it stops at line 1 or 2. The reason it feels mysterious is that the failure mode is identical whether the code is wrong, the bus is mismatched, or the pinout is off — the inverter simply reports no battery communication and gives you nothing else to work with.

Which Growatt Inverters Take a Battery?

Not every Growatt inverter manages storage. The hybrid and storage families do; the plain grid-tied string inverters don’t. In broad terms: SPH is the residential hybrid range with the widest battery support (the approved list above is issued against SPH models), SPF is the off-grid range typically paired with low-voltage packs, SPE is storage-focused, and WIT is the commercial hybrid line for larger banks. Growatt’s high-voltage grid-tied models such as the MIN XH-US take a different, much shorter battery list (Growatt’s own APX and ARO high-voltage packs, LG Prime and Enblock) — so a low-voltage 48V LFP pack that pairs happily with an SPH is not a candidate there.

If you’re still choosing the architecture rather than the battery, our low- vs high-voltage battery guide covers which class suits which job, and the hybrid inverter and battery pairing guide walks through the wiring and commissioning sequence. On the pack side, a 5.12 kWh 100Ah unit suits smaller stacks while a 10.24 kWh 200Ah unit is the common building block for whole-home backup.

Open Ecosystem: What Growatt Gives You (and What It Asks in Return)

Growatt sits on the open side of the industry split, and the trade is worth understanding before you commit to a platform.

That’s the honest deal: open platforms hand you leverage on price and choice, and hand you the verification work in exchange. It’s a good trade for anyone specifying more than one system a year. Australian installers have one more list to cross-check before ordering — whichever battery you pair, confirm it appears on the CEC approved battery list if the job needs to qualify for the federal rebate. For how the same split plays out elsewhere, see our guides to GoodWe compatibility (open, with its own 3-check test), Deye compatibility (open, and why the approved list isn’t the whole story), and Sungrow compatibility (closed — useful as the contrast). The inverter–battery compatibility hub explains open vs closed communication in depth.
